Objective: This study aims to determine the prevalence of Occult Hepatitis B and C Infections among Egyptian injection drug users (IDUs) and identify key risk factors contributing to their occurrence within this high-risk group.

Methods: In this cross-sectional study, 200 Egyptian IDUs were assessed. Participants were negative for Hepatitis B surface antigen and hepatitis C virus (HCV) RNA, with anti-HCV positive patients who achieved sustained virologic response after treatment included. Quantitative polymerase chain reaction (PCR) was used to detect HCV RNA in plasma and peripheral blood mononuclear cells, while HBV DNA was identified via nested PCR. Comparisons were made between Occult Hepatitis B infection (OBI) positive and OBI negative subgroups, as well as between other comprehensive income (OCI) positive and OCI negative subgroups. A significance level of 0.05 was set, with P-values below this indicating statistical significance. Statistical comparisons between OBI and OCI-positive and negative groups were performed using the Mann-Whitney U test and Chi-square test.

Results: OBI was found in 32% of IDUs, while OCI was detected in 42% of IDUs, and was present in 53.6% of seropositive individuals. All OBI patients showed a significant increase in all liver function tests, while OCI patients had significant elevations in alanine transaminase and aspartate transaminase values. HIV coinfection was identified in 39.1% and 26.1% of OBI and OCI cases respectively. OBI and OCI coinfection were detected in 31 patients.

Conclusion: Hidden infections such as OBI and OCI remain an overlooked public health issue in Egypt's IDU population. These findings highlight the need for targeted strategies to address these reservoirs of infection and could inform similar approaches in countries with comparable HBV/HCV epidemiology.

目的:本研究旨在确定埃及注射吸毒者(IDUs)中隐性乙型和丙型肝炎感染的流行情况,并确定在这一高危人群中导致其发生的关键危险因素。方法:在本横断面研究中,对200名埃及IDUs进行了评估。参与者乙型肝炎表面抗原和丙型肝炎病毒(HCV) RNA呈阴性,治疗后获得持续病毒学应答的抗HCV阳性患者包括在内。采用定量聚合酶链反应(PCR)检测血浆和外周血单个核细胞中的HCV RNA,采用巢式PCR检测HBV DNA。比较隐匿性乙型肝炎感染(OBI)阳性和OBI阴性亚组之间以及其他综合收入(OCI)阳性和OCI阴性亚组之间的差异。设置显著性水平为0.05,p值低于0.05表示具有统计学意义。采用Mann-Whitney U检验和卡方检验对OBI、oci阳性组和阴性组进行统计学比较。结果:32%的注射吸毒者检出OBI, 42%的注射吸毒者检出OCI, 53.6%的血清阳性个体检出OCI。所有OBI患者的所有肝功能检查均显著升高,而OCI患者的丙氨酸转氨酶和天冬氨酸转氨酶值均显著升高。合并感染HIV的OBI和OCI病例分别为39.1%和26.1%。31例患者检测到OBI和OCI合并感染。结论:在埃及IDU人群中,OBI和OCI等隐性感染仍然是一个被忽视的公共卫生问题。这些发现强调需要有针对性的战略来解决这些感染库,并可以为具有可比HBV/HCV流行病学的国家提供类似的方法。

Objective: The current study was conducted to investigate the effect of intermittent fasting (IF) with a low-carbohydrate-high-protein (LCHP) diet on blood glucose control in streptozotocin (STZ)-nicotinamide-induced type 2 diabetic rats (DR).

Methods: Thirty male Wistar rats were divided into six groups (n = 5) including a group of normal rats (NR) that received a control diet (CD) (50% carbohydrates, 17% protein, and 33% fat) with ad libitum (AL) feeding. The remaining 5 groups were DR injected with STZ and fed on CD or LCHP diet (40% carbohydrates, 30% protein, and 30% fat) for 6 weeks, either AL or IF (with a time-restricted feeding of 16 h followed by 8 h feeding period). There was a standard control group treated with metformin and fed on CD with AL feeding. A random blood glucose was measured. Changes in body weight and feed intake (FI) were monitored weekly.

Results: Feeding rats on LCHP and IF and their combination significantly reduced FI, body weight gain, blood glucose (P < 0.001), and improved insulin resistance (P < 0.05) with no effect on the insulin levels (P > 0.05). LCHP and IF decreased the levels of triglycerides and very-low-density lipoprotein and showed a possible protection against atherosclerosis by reducing the atherogenic index (P < 0.01). Furthermore, LCHP+IF greatly alleviates the pancreatic histopathological changes induced by STZ and showed the normal histological structure of the Langerhans islets.

Conclusion: IF with a LCHP diet could be effectively used in improving the indicators of glucose control, and reversing pancreatic histopathological alterations in type 2 diabetes.

目的:研究低碳水化合物高蛋白(LCHP)间歇禁食(IF)对链脲佐菌素(STZ)-烟酰胺诱导的2型糖尿病大鼠(DR)血糖控制的影响。方法:将30只雄性Wistar大鼠分为6组(n = 5),其中正常大鼠(NR)饲喂对照日粮(CD)(50%碳水化合物,17%蛋白质,33%脂肪),随意饲喂(AL)。其余5组均DR注射STZ,分别饲喂乳清或低脂低碳(碳水化合物40%、蛋白质30%、脂肪30%)饲粮(AL或IF) 6周(限时饲喂16 h,饲喂期8 h)。标准对照组给予二甲双胍治疗,以CD加AL喂养。随机测量血糖。每周监测体重和采食量的变化。结果:LCHP和IF及其联合喂养大鼠可显著降低FI、体重增加、血糖(P < 0.001),改善胰岛素抵抗(P < 0.05),但对胰岛素水平无影响(P < 0.05)。LCHP和IF降低了甘油三酯和极低密度脂蛋白水平,并可能通过降低动脉粥样硬化指数来预防动脉粥样硬化(P < 0.01)。LCHP+IF显著减轻STZ诱导的胰腺组织病理改变,使朗格汉斯胰岛的组织结构恢复正常。结论:低脂低糖饮食可有效改善2型糖尿病患者血糖控制指标,逆转胰腺组织病理学改变。

Objective: Gastrointestinal stromal tumor (GIST) is the most common type of mesenchymal tumor accounting for 2.2% of all malignant gastric tumors. Mesenchymal stem cells (MSCs) play crucial roles in gastric carcinogenesis. In addition, Helicobacter pylori has been linked to GIST as it induces an epithelial response that can home MSCs to the stomach mucosa. This study aimed to investigate the relationship between H. pylori-infected gastric mucosa and the development of CD117-positive GIST and evaluate the prognosis of H. pylori-infected gastric mucosa of GIST patients that received anti-CD117 therapy.

Methods: This is a retrospective study conducted on H. pylori-infected GIST patients diagnosed between 2015 and 2021. The follow-up period was performed for a minimum of 2 years. Clinicopathological factors for each patient were collected from cases selected from the Registry of Pathology and Surgery Departments at Assiut University Hospitals.

Results: There was a statistically significant difference between our study population regarding the overall survival of studied patients, disease-free survival of studied patients, and the relationship between H. pylori-infected gastric mucosa and development, grading, therapy response, and overall survival of GIST except in status at last follow-up.

Conclusions: Our study is the first to reveal that H. pylori infection is linked to a worse prognosis for GIST patients. H. pylori has the potential to be used as a strong predictive biomarker for GIST individuals in the future. Clinical research with large samples as well as prospective designs are needed to confirm this connection.

目的:胃肠道间质瘤(GIST)是最常见的间质肿瘤类型,占胃恶性肿瘤的2.2%。间充质干细胞(MSCs)在胃癌发生中起着至关重要的作用。此外,幽门螺杆菌与胃肠道间质瘤有关,因为它能诱导上皮反应,使间充质干细胞转移到胃粘膜。本研究旨在探讨幽门螺杆菌感染胃黏膜与cd117阳性胃肠道间质瘤发展的关系,并评价经抗cd117治疗的幽门螺杆菌感染胃肠道间质瘤患者的预后。方法:回顾性研究2015 - 2021年间诊断为幽门螺杆菌感染的GIST患者。随访期至少为2年。每位患者的临床病理因素从阿西尤特大学附属医院病理学和外科登记处选择的病例中收集。结果:我们的研究人群在研究患者的总生存期、无病生存期以及幽门螺杆菌感染的胃粘膜与GIST的发展、分级、治疗反应和总生存期的关系方面,除末次随访状态外,差异均有统计学意义。结论:我们的研究首次揭示了幽门螺杆菌感染与胃肠道间质瘤患者预后较差有关。幽门螺杆菌有潜力在未来作为胃肠道间质瘤个体的强有力的预测生物标志物。需要大样本的临床研究以及前瞻性设计来证实这种联系。

Objective: Dasatinib (DTB) is a second-generation tyrosine kinase inhibitor that was found it could help with lung cancer treatment. However, DTB has low aqueous solubility and poor bioavailability due to its incomplete absorption and high first-pass effect. The objective of this study was to improve DTB's solubility, delivery, and efficacy as a potential lung cancer treatment by developing an inhalable DTB-nanoemulsion (DNE) formulation.

Methods: The DNE formulation was prepared by the spontaneous emulsification method, using oleic acid as the oil phase and a mixture of Kolliphor RH 40 and dipropylene glycol as surfactant. Compared with free DTB, the DNE formulation enhanced the aqueous solubility, flow property, and delivery of DTB to the lungs with a good fine-particle dose, fine-particle fraction, and mass median aerodynamic diameter.

Results: The DNE formulation was safe on lung cancer cells when the cell viability and toxicity were evaluated and IC50 values were found to be 0.0431 μg/mL and 0.0443 μg/mL on A549 and Calu-3 cells, respectively. Moreover, DNE formulation significantly increased its anti-cancer effectiveness against A549 and Calu-3 lung cancer cells by interfering with cell cycle progression through apoptosis or cell cycle arrest.

Conclusion: The nanoemulsion formulation has the potential to be an effective carrier for DTB, which could possibly be used to treat lung cancer.

目的:达沙替尼(DTB)是一种第二代酪氨酸激酶抑制剂,被发现可以帮助治疗肺癌。但DTB的溶解度低,生物利用度差,吸收不完全,首过效应高。本研究的目的是通过开发一种可吸入的DTB纳米乳(DNE)配方来改善DTB的溶解度、递送和作为潜在肺癌治疗的疗效。方法:以油酸为油相,以Kolliphor RH 40和二丙二醇的混合物为表面活性剂,采用自发乳化法制备DNE配方。与游离DTB相比,DNE配方以良好的细颗粒剂量、细颗粒分数和质量中位气动直径增强了DTB的水溶性、流动性和向肺部的输送。结果:经细胞活力和毒性评价,DNE制剂对肺癌细胞是安全的,对A549和Calu-3细胞的IC50值分别为0.0431 μg/mL和0.0443 μg/mL。此外,DNE配方通过凋亡或细胞周期阻滞干扰细胞周期进程,显著提高了其对A549和Calu-3肺癌细胞的抗癌效果。结论:该纳米乳制剂具有作为DTB有效载体的潜力,有可能用于治疗肺癌。

Objective: In spite of great advance in the management of hepatocellular carcinoma (HCC), the prognostic factors are still obviously not understood. The role of tumor budding (TB) and tumor-infiltrating lymphocytes (TILs) in HCC as pathological parameters affecting prognosis stands principally unknown.

Methods: Seventy-four surgical resection pathology specimens of HCC patients were used. Assessment of TB and TILs were performed using hematoxylin-eosin-stained slides. Follow-up data were collected over a 5-year period to determine disease-free survival rates, overall survival (OS) rates, and how they related to TB, TILs, and other clinicopathological factors.

Results: There was a significant statistical association between high-grade TB and lymphovascular embolization (LVE), tumor necrosis, and grade of HCC with P = 0.003, 0.036, and 0.017, respectively. The positive TILs group showed a statistically significant correlation with histological grade, LVE, and serum alpha-fetoprotein (AFP) level with P = 0.002, 0.006, and 0.043, respectively. Multivariate analysis using the Cox proportional hazard model revealed that TILs are not an independent pathological factor for disease-free and OS, although TB is an independent pathological factor for both.

Conclusions: In all HCC patients, TB was seen, and there was a significant link between the grade of the HCC and the presence of tumor necrosis, LVE, and high-grade TB. The majority (92%) of HCC patients had TILs, and there was a strong relationship between the histological grade, LVE, and serum AFP level. While TILs show variation of the immunologic reaction to the tumor, TB tends to suggest a hostile biologic nature and a bad prognosis.

目的:尽管肝细胞癌(HCC)的治疗取得了很大进展,但预后因素仍明显不明。HCC中的肿瘤萌芽(TB)和肿瘤浸润淋巴细胞(TILs)作为影响预后的病理参数,其作用尚不明确:方法:采用74例HCC患者的手术切除病理标本。方法:采用 74 例 HCC 患者的手术切除病理标本,使用苏木精-伊红染色的切片对 TB 和 TIL 进行评估。收集了5年的随访数据,以确定无病生存率、总生存率(OS)以及它们与TB、TIL和其他临床病理因素的关系:高级别结核与淋巴管栓塞(LVE)、肿瘤坏死和HCC分级之间存在明显的统计学关联,P分别为0.003、0.036和0.017。TILs阳性组与组织学分级、LVE和血清甲胎蛋白(AFP)水平有统计学意义的相关性,P=0.002、0.006和0.043。使用Cox比例危险模型进行的多变量分析表明,TILs不是影响无病生存率和OS的独立病理因素,但TB是影响无病生存率和OS的独立病理因素:结论:在所有 HCC 患者中均可见 TB,HCC 的分级与肿瘤坏死、LVE 和高级别 TB 的存在之间存在显著联系。大多数(92%)HCC 患者有 TILs,组织学分级、LVE 和血清 AFP 水平之间存在密切联系。TILs显示了肿瘤免疫反应的变化,而TB则倾向于提示肿瘤的敌对生物性质和不良预后。

Objective: The differentiation between reactive atypical changes and dysplasia/carcinoma in the daily cases of cholecystectomies is a routine histopathological challenge. Up to our knowledge, no immunohistochemical marker can definitely differentiate between these two changes. Many promising markers have been proposed to be helpful tools in this situation. One of them is B-cell lymphoma-2 (BCL-2) immunohistochemical stain. Therefore, this study aims to evaluate its usefulness as a marker that might be helpful in such challenging cases.

Methods: From the archive of the histopathology laboratories of Qassim University Medical City and King Fahad Specialist Hospital in Qassim, five dysplastic/neoplastic gallbladder cases were collected (in the shape of formalin-fixed, paraffin-embedded blocks) as well as five cholecystitis with reactive atypical changes cases. Two slides from each block were prepared: One was stained with H&E and the other was stained immunohistochemically with BCL-2. The slides were evaluated by two histopathologist consultants in the same sitting using multiheaded microscope to confirm the original diagnosis and to evaluate the BCL-2 staining.

Results: Five dysplastic/carcinoma cases and five cholecystitis with reactive atypia were collected. The original diagnoses were confirmed by two pathologists. They also confirmed that all the BCL-2 stained slides (with the exception of one reactive case) were negative for BCL-2 immunohistochemical stain.

Conclusion: BCL-2 immunohistochemical stain is not a promising marker in the differentiation between reactive epithelium and dysplasia/carcinoma in the gallbladder.

目的:在日常的胆囊切除术中,如何区分反应性不典型改变和发育不良/癌是一项常规的组织病理学挑战。据我们所知,还没有一种免疫组化标记物能明确区分这两种病变。在这种情况下,许多有前途的标记物被认为是有用的工具。其中之一就是 B 细胞淋巴瘤-2(BCL-2)免疫组化染色。因此,本研究旨在评估BCL-2作为一种标记物在这类具有挑战性的病例中的实用性:从卡西姆大学医学城和卡西姆法赫德国王专科医院组织病理学实验室的档案中收集了五例发育不良/肿瘤性胆囊病例(福尔马林固定、石蜡包埋切片)和五例伴有反应性非典型改变的胆囊炎病例。每个切片块均制备了两张切片:一张用 H&E 染色,另一张用 BCL-2 进行免疫组化染色。切片由两名组织病理学家顾问使用多头显微镜进行评估,以确认最初的诊断并评估 BCL-2 染色结果:结果:共收集到五例发育不良/癌病例和五例伴有反应性不典型性的胆囊炎病例。两名病理学家确认了最初的诊断。他们还证实,所有经 BCL-2 染色的切片(一例反应性病例除外)BCL-2 免疫组化染色均为阴性:结论:BCL-2免疫组化染色不是区分胆囊反应性上皮和发育不良/癌的有效标志物。

Objective: The alarming increase in vitamin D deficiency (VDD) has been shown to result in compounded risks of major health problems globally. As sickle cell disease (SCD) children are already health compromised, the co-morbidities escalate early in life, demanding an early detection, to minimize the adverse effects. This study determined vitamin D levels in children with SCD without a crisis to check for probable associations with inflammation and infections if any.

Methods: SCD children aged 5-16 years, in a steady state, were enrolled in the study after taking necessary consent and ethical clearance. Hb, serum calcium, vitamin D, and high-sensitivity C-reactive protein (hsCRP) levels were analyzed.

Results: VDD was seen in most of the children with SCD irrespective of gender and age. Males aged 5-10 years showed significance (P = 0.0375) with vitamin D and white blood cell (WBC) (P = 0.0015) but males aged 11-16-year age group exhibited a very strong-positive correlation with vitamin D (r = 0.9862) and a very strong-negative correlation with Hb (r = -0.9819) and hsCRP (r = -0.9907). Among females, the 11-16-year age group patients exhibited a significant association with vitamin D (P = 0.0487), Ca (P = 0.0118), Hb (P = 0.0007), and hsCRP (P = 0.0001) levels. Correlation "r" values in this age group show a strong-negative correlation with WBC levels (r = -0.6525) as well as hsCRP (r = - 0.6550).

Conclusion: The increased deficiency of vitamin D in SCD children should be addressed at early ages of life, to reduce the occurrence and severity of associated comorbidities.

目的:维生素 D 缺乏症(VDD)的惊人增长已在全球范围内导致重大健康问题的复合风险。由于镰状细胞病(SCD)患儿的健康状况已经受到损害,其并发症在生命早期就会增加,因此需要及早发现,以尽量减少不良影响。本研究测定了未发生危机的 SCD 儿童的维生素 D 水平,以检查是否可能与炎症和感染有关:方法:在征得必要的同意并通过伦理审查后,将 5-16 岁处于稳定状态的 SCD 儿童纳入研究。对血红蛋白、血清钙、维生素 D 和高敏 C 反应蛋白(hsCRP)水平进行了分析:结果:大多数 SCD 患儿都出现了 VDD,与性别和年龄无关。5-10 岁的男性与维生素 D 和白细胞(WBC)(P = 0.0015)呈显著相关(P = 0.0375),但 11-16 岁年龄组的男性与维生素 D 呈极强的正相关(r = 0.9862),而与血红蛋白(r = -0.9819)和高敏 C 反应蛋白(hsCRP)(r = -0.9907)呈极强的负相关。在女性患者中,11-16 岁年龄组患者与维生素 D(P = 0.0487)、Ca(P = 0.0118)、Hb(P = 0.0007)和 hsCRP(P = 0.0001)水平有显著相关性。该年龄组的相关 "r "值与白细胞水平(r = -0.6525)和 hsCRP(r = - 0.6550)呈强负相关:结论:SCD 儿童维生素 D 缺乏症的增加应在生命早期得到解决,以减少相关并发症的发生和严重程度。

MicroRNA-183-5p negatively regulates interleukin-8 expression in cervical cancer cells. MicroRNA-183-5p 负向调节宫颈癌细胞中白细胞介素-8 的表达。
IF 2 Q2 MEDICINE, GENERAL & INTERNAL Pub Date : 2024-11-01

Objectives: Interleukin-8 (IL-8) and microRNA-183-5p (hsa-miR-183-5p) have been implicated in the development of cervical cancer, yet their relationship has not been explored. This study aims to determine whether phorbol 12-myristate 13-acetate (PMA)-induced IL-8 expression is regulated by hsa-miR-183-5p in cervical cancer cells.

Methods: Bioinformatics algorithms were employed to predict the potential binding of hsa-miR-183-5p to the 3'UTR of IL-8 mRNA. CaSKi cervical cancer cells were used as a model to investigate this regulation. The expression levels of hsa-miR-183-5p and IL-8 were measured using Taqman assays through real-time polymerase chain reaction, while IL-8 protein levels were quantified in culture media through IL-8 specific Sandwich enzyme-linked immunosorbent assays. Luciferase reporter assays and transfections with pre- or anti-miR-183-5p were conducted to validate the binding of hsa-miR-183-5p to IL-8 mRNA's 3'UTR.

Results: The bioinformatics tool TargetScan identified a seed-matched sequence for hsa-miR-183-5p in the 3'UTR of IL-8 mRNA. PMA-induced IL-8 expression was inversely correlated with hsa-miR-183-5p down regulation in cervical cancer cells. hsa-miR-183-5p significantly reduced luciferase activity in the 3'UTR-IL-8 reporter assay. Transfection with pre-miR-183-5p led to a notable decrease in IL-8 mRNA and protein secretion, while anti-miR-183-5p transfection caused a significant increase in IL-8 mRNA and protein levels in PMA-treated cells.

Conclusion: This study is the first to demonstrate that hsa-miR-183-5p directly regulates IL-8 expression in cervical cancer cells. Both IL-8 and hsa-miR-183-5p could serve as potential therapeutic targets in the treatment of cervical cancer.

研究目的白细胞介素-8(IL-8)和microRNA-183-5p(hsa-miR-183-5p)被认为与宫颈癌的发展有关,但它们之间的关系尚未得到探讨。本研究旨在确定在宫颈癌细胞中,光稳定剂 12-肉豆蔻酸 13-乙酸酯(PMA)诱导的 IL-8 表达是否受 hsa-miR-183-5p 的调控:方法:采用生物信息学算法预测 hsa-miR-183-5p 与 IL-8 mRNA 3'UTR 的潜在结合。以 CaSKi 宫颈癌细胞为模型研究这种调控。通过实时聚合酶链式反应,使用 Taqman 法测定 hsa-miR-183-5p 和 IL-8 的表达水平;通过 IL-8 特异性 Sandwich 酶联免疫吸附试验,定量检测培养基中 IL-8 蛋白水平。为了验证 hsa-miR-183-5p 与 IL-8 mRNA 的 3'UTR 的结合情况,进行了荧光素酶报告实验和转染前或抗 miR-183-5p:结果:生物信息学工具 TargetScan 在 IL-8 mRNA 的 3'UTR 中发现了 hsa-miR-183-5p 的种子匹配序列。在宫颈癌细胞中,PMA 诱导的 IL-8 表达与 hsa-miR-183-5p 的下调成反比。转染pre-miR-183-5p后,IL-8 mRNA和蛋白分泌明显减少,而转染anti-miR-183-5p后,PMA处理细胞中IL-8 mRNA和蛋白水平明显增加:结论:本研究首次证明了 hsa-miR-183-5p 直接调控宫颈癌细胞中 IL-8 的表达。IL-8和hsa-miR-183-5p都可以作为治疗宫颈癌的潜在靶点。

Objective: Schiff bases are versatile chemical compounds extensively used in various applications, including as catalysts, polymer stabilizers, pigments, dyes, and building blocks for organic synthesis. In addition, they exhibit a wide range of biological activities, such as antifungal, antibacterial, antiviral, antiproliferative, anti-inflammatory, and antipyretic effects.

Methods: A novel Schiff base ligand (HL) was synthesized by condensing isatin with 2,6-diaminopyridine and isoleucine, followed by the preparation of transition metal complexes. The ligand and complexes were characterized using techniques such as elemental analysis, IR, 1H-NMR, UV-vis spectroscopy, mass spectrometry, and thermal analysis. Antimicrobial, antiproliferative activities, and structural investigations through X-ray diffraction and scanning electron microscopy were also evaluated.

Results: The complexes were identified as [Cr(L)Cl(H2O)]Cl·2H2O, [Fe(L)Cl2], [M(L)]Cl·nH2O, and [M(L)(H2O)2]Cl, where M represents Mn(II), Cu(II), Cd(II), Co(II), Zn(II), and Ni(II). Thermogravimetric analysis showed initial water loss, followed by decomposition of anionic compounds and ligands. The ligand forms a uninegative-tetradentate bond with the metal ions, and all complexes, except Fe(III), exhibit electrolytic behavior. Most complexes displayed tetrahedral geometry, while Ni(II), Co(II), and Zn(II) had octahedral geometry. The metal complexes showed enhanced antibacterial, antifungal, and antiproliferative activity against MCF-7 breast cancer cells compared to the free ligand. Molecular docking studies indicated inhibitory potential against receptors 1GS4, 2HQ6, 3DJD, and 5JPE.

Conclusion: These newly synthesized ligands and complexes show promise as therapeutic agents against infections and cancer, though further studies are needed to understand their mechanisms.

目的:希夫碱是一种用途广泛的化合物,被广泛应用于各种领域,包括用作催化剂、聚合物稳定剂、颜料、染料和有机合成的基质。此外,它们还具有广泛的生物活性,如抗真菌、抗细菌、抗病毒、抗增殖、抗炎和解热作用:方法:通过将靛红与 2,6-二氨基吡啶和异亮氨酸缩合,合成了一种新型希夫碱配体(HL),然后制备了过渡金属配合物。使用元素分析、红外光谱、1H-NMR、紫外-可见光谱、质谱分析和热分析等技术对配体和配合物进行了表征。此外,还通过 X 射线衍射和扫描电子显微镜对抗菌、抗增殖活性和结构进行了评估:这些配合物被鉴定为 [Cr(L)Cl(H2O)]Cl-2H2O、[Fe(L)Cl2]、[M(L)]Cl-nH2O 和 [M(L)(H2O)2]Cl,其中 M 代表 Mn(II)、Cu(II)、Cd(II)、Co(II)、Zn(II) 和 Ni(II)。热重分析表明,初始失水,随后阴离子化合物和配体分解。配体与金属离子之间形成了一个无负四价键,除铁(III)外,所有络合物都表现出电解行为。大多数配合物呈四面体几何形状,而 Ni(II)、Co(II) 和 Zn(II) 则呈八面体几何形状。与游离配体相比,金属配合物对 MCF-7 乳腺癌细胞具有更强的抗菌、抗真菌和抗增殖活性。分子对接研究表明,它们对 1GS4、2HQ6、3DJD 和 5JPE 受体具有抑制潜力:这些新合成的配体和复合物有望成为抗感染和癌症的治疗药物,但还需要进一步的研究来了解它们的作用机制。
