The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.
中药金振口服液(JZOL)与西药在治疗急性支气管炎(AB)患儿方面的比较结果令人鼓舞。这项试验评估了金樱子口服液改善急性支气管炎患儿咳嗽和排痰的疗效和安全性。480名儿童被随机分配服用JZOL或盐酸氨溴索和盐酸克仑特罗口服溶液7天。主要结果是咳嗽缓解时间。两组咳嗽缓解时间的中位数均为 5.0 天,而止咳药起效时间的中位数仅为 1 天。这项随机对照试验表明,在治疗咳嗽、咳痰方面,JZOL的疗效并不亚于止咳化痰的西药,而且可以综合治疗呼吸道和全身不适症状。结合临床试验,通过网络靶点分析揭示了JZOL抗AB的机制,发现IL-1/IL1R/TRPV1/TRPA1、NGF/TrkA/TRPV1/TRPA1、PGE2/EP/PKA/TRPV1/TRPA1等TRP通道中的通路可能发挥了重要作用。动物实验进一步证实,JZOL治疗AB的炎症和免疫调节作用至关重要,而TRP通道是其关键的作用机制。

Alcoholic steatohepatitis (ASH) is a liver disease characterized by steatosis, inflammation, and necrosis of the liver tissue as a result of excessive alcohol consumption. Pregnane X receptor (PXR) is a xenobiotic nuclear receptor best known for its function in the transcriptional regulation of drug metabolism and disposition. Clinical reports suggested that the antibiotic rifampicin, a potent human PXR activator, is a contraindication in alcoholics, but the mechanism was unclear. In this study, we showed that the hepatic expression of fatty acid binding protein 4 (FABP4) was uniquely elevated in ASH patients and a mouse model of ASH. Pharmacological inhibiting FABP4 attenuated ASH in mice. Furthermore, treatment of mice with the mouse PXR agonist pregnenolon-16-carbonitrile (PCN) induced the hepatic and circulating levels of FABP4 and exacerbated ASH in a PXR-dependent manner. Our mechanism study established FABP4 as a transcriptional target of PXR. Treatment with andrographolide, a natural compound and dual inhibitor of PXR and FABP4, alleviated mice from ASH. In summary, our results showed that the PXR–FABP4 gene regulatory axis plays an important role in the progression of ASH, which may have accounted for the contraindication of Rifampicin in patients of alcoholic liver disease. Pharmacological inhibition of PXR and/or FABP4 may have its promise in the clinical management of ASH.
酒精性脂肪性肝炎(ASH)是一种肝脏疾病,其特征是由于过量饮酒导致的肝组织脂肪变性、发炎和坏死。孕烷 X 受体(PXR)是一种异种生物核受体,因其对药物代谢和处置的转录调控功能而最为人熟知。临床报告显示,抗生素利福平(一种强效的人类 PXR 激活剂)是酗酒者的禁忌药物,但其机制尚不清楚。在这项研究中,我们发现在 ASH 患者和 ASH 小鼠模型中,脂肪酸结合蛋白 4(FABP4)的肝脏表达独特地升高。药物抑制 FABP4 可减轻小鼠的 ASH。此外,用小鼠 PXR 激动剂孕烯诺龙-16-甲腈(PCN)处理小鼠会诱导肝脏和循环中的 FABP4 水平,并以 PXR 依赖性方式加剧 ASH。我们的机制研究确定了 FABP4 是 PXR 的转录靶标。穿心莲内酯是一种天然化合物,也是 PXR 和 FABP4 的双重抑制剂。总之,我们的研究结果表明,PXR-FABP4基因调控轴在ASH的进展中起着重要作用,这可能是酒精性肝病患者禁用利福平的原因。药物抑制PXR和/或FABP4可能有望用于ASH的临床治疗。

Oxaliplatin (OXA), a platinum-based chemotherapeutic agent, remains a mainstay in first-line treatments for advanced colorectal cancer (CRC). However, the eventual development of OXA resistance represents a significant clinical challenge. In the present study, we demonstrate that the aldo-keto reductase 1C1 (AKR1C1) is overexpressed in CRC cells upon acquisition of OXA resistance, evident in OXA-resistant CRC cell lines. We employed genetic silencing and pharmacological inhibition strategies to establish that suppression of AKR1C1 restores OXA sensitivity. Mechanistically, AKR1C1 interacts with and activates the transcription factor STAT3, which upregulates the glutamate transporter EAAT3, thereby elevating intracellular glutathione levels and conferring OXA resistance. Alantolactone, a potent natural product inhibitor of AKR1C1, effectively reverses this chemoresistance, restricting the growth of OXA-resistant CRC cells both and . Our findings uncover a critical AKR1C1-dependent mechanism behind OXA resistance and propose a promising combinatorial therapeutic strategy to overcome this resistance in CRC.
奥沙利铂(OXA)是一种铂类化疗药,目前仍是晚期结直肠癌(CRC)一线治疗的主要药物。然而,OXA 最终产生耐药性是一项重大的临床挑战。在本研究中,我们证明了醛酮还原酶 1C1 (AKR1C1) 在获得 OXA 耐药性后会在 CRC 细胞中过表达,这在 OXA 耐药性 CRC 细胞系中非常明显。我们采用基因沉默和药物抑制策略,证实抑制 AKR1C1 可恢复对 OXA 的敏感性。从机理上讲,AKR1C1 与转录因子 STAT3 相互作用并激活其上调谷氨酸转运体 EAAT3,从而提高细胞内谷胱甘肽水平并赋予 OXA 抗性。金刚烷内酯是一种强效的 AKR1C1 天然产物抑制剂,它能有效逆转这种化疗耐药性,同时限制对 OXA 具有耐药性的 CRC 细胞的生长。我们的研究结果揭示了 OXA 耐药性背后一个关键的 AKR1C1 依赖性机制,并提出了一种很有前景的组合治疗策略来克服 CRC 中的这种耐药性。

Currently, about 40% of approved drugs and nearly 90% of drug candidates are poorly water-soluble drugs. Low solubility reduces the likelihood that these drugs can be effectively used clinically. Effectively improving the solubility and bioavailability of poorly water-soluble drugs is a critical issue that needs to be urgently addressed in drug development and application. This review briefly introduces the conventional solubilization techniques such as solubilizers, hydrotropes, cosolvents, prodrugs, salt modification, micronization, cyclodextrin inclusion, solid dispersions, and details the crystallization strategies, ionic liquids, and polymer-based, lipid-based, and inorganic-based carriers in improving solubility and bioavailability. Some of the most commonly used approved carrier materials for solubilization techniques are presented, and some approved poorly water-soluble drugs using solubilization techniques are summarized. Furthermore, this review describes in detail the solubilization mechanism of each solubilization technique, reviews the latest research advances and challenges, and evaluates the potential for clinical translation. This review could guide the selection of a solubilization approach, dosage form, and administration route for poorly water-soluble drugs. Moreover, we discuss several promising solubilization techniques attracting increasing attention worldwide.

The underlying cause of low response rates to existing immunotherapies is that tumor cells dominate tumor immune escape through surface antigen deficiency and inducing tumor immunosuppressive microenvironment (TIME). Here, we proposed an tumor cell engineering strategy to disrupt tumor immune escape at the root by restoring tumor cell MHC-I/tumor-specific antigen complex (MHC-I/TSA) expression to promote T-cell recognition and by silencing tumor cell CD55 to increase the ICOSL B-cell proportion and reverse the TIME. A doxorubicin (DOX) and dual-gene plasmid (MAC pDNA, encoding both MHC-I/ASMTNMELM and CD55-shRNA) coloaded drug delivery system (LCPN@ACD) with tumor targeting and charge/size dual–conversion properties was prepared. LCPN@ACD-induced ICD promoted DC maturation and enhanced T-cell activation and infiltration. LCPN@ACD enabled effective expression of MHC-I/TSA on tumor cells, increasing the ability of tumor cell recognition and killing. LCPN@ACD downregulated tumor cell CD55 expression, increased the proportion of ICOSL B cells and CTLs, and reversed the TIME, thus greatly improving the efficacy of PD-1 and CAR-T therapies. The application of this tumor cell engineering strategy eliminated the source of tumor immune escape, providing new ideas for solving the challenges of clinical immunotherapy.
现有免疫疗法反应率低的根本原因是肿瘤细胞通过表面抗原缺乏和诱导肿瘤免疫抑制微环境(TIME)主导了肿瘤免疫逃逸。在此,我们提出了一种肿瘤细胞工程策略,通过恢复肿瘤细胞MHC-I/肿瘤特异性抗原复合物(MHC-I/TSA)表达以促进T细胞识别,以及沉默肿瘤细胞CD55以增加ICOSL B细胞比例并逆转TIME,从根本上破坏肿瘤免疫逃逸。研究人员制备了具有肿瘤靶向和电荷/大小双转换特性的多柔比星(DOX)和双基因质粒(MAC pDNA,同时编码MHC-I/ASMTNMELM和CD55-shRNA)共载给药系统(LCPN@ACD)。LCPN@ACD诱导的ICD促进了DC的成熟,增强了T细胞的活化和浸润。LCPN@ACD能使肿瘤细胞上的MHC-I/TSA有效表达,从而提高识别和杀伤肿瘤细胞的能力。LCPN@ACD 下调了肿瘤细胞 CD55 的表达,增加了 ICOSL B 细胞和 CTL 的比例,逆转了 TIME,从而大大提高了 PD-1 和 CAR-T 疗法的疗效。这种肿瘤细胞工程策略的应用消除了肿瘤免疫逃逸的源头,为解决临床免疫治疗难题提供了新思路。

LCPN@ACD downregulated tumor cell CD55 expression, increased the proportion of ICOSL B cells and CTLs, and reversed the TIME, thus greatly improving the efficacy of PD-1 and CAR-T therapies. The application of this tumor cell engineering strategy eliminated the source of tumor immune escape, providing new ideas for solving the challenges of clinical immunotherapy.","PeriodicalId":6906,"journal":{"name":"Acta Pharmaceutica Sinica.

encodes a DNA methyltransferase involved in development, cell differentiation, and gene transcription, which is mutated and aberrant-expressed in cancers. Here, we revealed that loss of promotes malignant phenotypes in lung cancer. Based on the epigenetic inhibitor library synthetic lethal screening, we found that small-molecule HDAC6 inhibitors selectively killed -defective NSCLC cells. Knockdown of by siRNAs reduced cell growth and induced apoptosis in -defective NSCLC cells. However, sensitive cells became resistant when was rescued. Furthermore, the selectivity to HDAC6 inhibition was recapitulated in mice, where an HDAC6 inhibitor retarded tumor growth established from -defective but not parental NSCLC cells. Mechanistically, loss resulted in the upregulation of through decreasing its promoter CpG methylation and enhancing transcription factor RUNX1 binding. Notably, our results indicated that HIF-1 pathway was activated in -defective cells whereas inactivated by HDAC6 inhibition. Knockout of contributed to the elimination of synthetic lethality between and . Interestingly, HIF-1 pathway inhibitors could mimic the selective efficacy of HDAC6 inhibition in -defective cells. These results demonstrated as an HIF-1-dependent vulnerability of -defective cancers. Together, our findings identify as a potential HIF-1-dependent therapeutic target for the treatment of -defective cancers like NSCLC.
编码一种 DNA 甲基转移酶,参与发育、细胞分化和基因转录,在癌症中会发生突变和异常表达。在这里,我们发现该基因的缺失会促进肺癌的恶性表型。基于表观遗传抑制剂库的合成致死筛选,我们发现小分子 HDAC6 抑制剂能选择性地杀死缺失的 NSCLC 细胞。通过 siRNAs 敲除 HDAC6 抑制剂可降低细胞生长,并诱导-缺陷 NSCLC 细胞凋亡。然而,敏感细胞在被挽救后会变得耐药。此外,HDAC6抑制剂对HDAC6抑制的选择性在小鼠中得到了再现,HDAC6抑制剂能延缓由-缺陷NSCLC细胞而非亲代NSCLC细胞所形成的肿瘤生长。从机理上讲,HDAC6的缺失通过降低其启动子CpG甲基化和增强转录因子RUNX1的结合而导致其上调。值得注意的是,我们的研究结果表明,HIF-1通路在-缺陷细胞中被激活,而HDAC6抑制则使其失活。有趣的是,HIF-1 通路抑制剂可以模拟 HDAC6 抑制剂在-缺陷细胞中的选择性功效。这些结果表明,-缺陷癌症具有依赖于 HIF-1 的脆弱性。总之,我们的研究结果确定了治疗 NSCLC 等-缺陷癌症的潜在 HIF-1 依赖性治疗靶点。
