Globally, healthcare is concerned about the rising prevalence of type 2 diabetes. Phytochemicals from medicinal plants have shown great promise in improving human health. The present study aimed to determine the secondary metabolites of Ziziphus oenopolia (L.) fruit extract that contribute to its anti-diabetic activity. The anti-diabetic properties were assessed by in vitro and in silico approaches using α-amylase and α-glucosidase inhibitory assays. Gas chromatography and mass spectroscopy analyses were used to profile Z. oenopolia fruit contents, and a total of four bioactive chemicals and eight phytocompounds were tentatively identified, including flavonoids, terpenoids, phenols, steroids, tannins, and saponins. The Z. oenopolia fruit hydroalcoholic extract inhibits α-amylase and α-glucosidase enzymes in a dose-dependent manner (IC50 = 328.76 and 337.28 µg/mL, R2 = 0.979 and 0.981). Additionally, phytochemicals found in Z. oenopolia fruit exhibit the ability to inhibit anti-diabetic targets, specifically α-amylase and α-glucosidase (2QV4 vs 3A4A; correlation coefficient, r = 0.955), as demonstrated by computational analysis. This establishes the fruit as a promising and environmentally friendly option for treating hyperglycemia, highlighting the positive correlation between anti-diabetic objectives.

In the current work, bis-thiourea derivatives have been synthesized through condensation reaction between isothiocynates and diamines in dry acetone to form SK1 (1,2-bis(N-benzoylthioureido) benzene), SK2 (1,3-bis(N-benzoylthioureido) benzene), and SK3 (1,4-bis(N-benzoylthioureido) benzene). The structures of new synthesized derivatives were confirmed through melting point and spectroscopic technique such as 1HNMR only. The synthesized compounds were assessed for acute toxicity test and are proved free of toxicity. The derivatives were further tested as anti-inflammatory agents by in vitro lipoxygenase enzyme inhibition studies, molecular docking, and in vivo carrageenan-induced paw edema assay, and histamine-induced edema test. The overall observations presented that compounds SK1 and SK3 possess promising anti-inflammatory potential, while compound SK2 is found to be a good anti-inflammatory agent.

The build-up of synthetic dyes in the environment and aquatic ecology is a significant environmental issue due to their inability to break down naturally. The overuse of chemical fungicides also poses a threat to the environment due to their accumulation and fostering of fungal resistance. Hence, the study was conducted to detect the antifungal properties and photocatalytic activity of greenly synthesized iron oxide nanoparticles (IONPs) prepared using the Hibiscus sabdariffa flower extract. The biogenic IONPs showed the highest photocatalytic activity against rhodamine B dye at a concentration of 4.0 mg/ml. The biogenic IONPs also demonstrated effective antifungal properties against Penicillium digitatum and Aspergillus niger strains, with relative inhibition percentages of mycelial growth being higher than those with the metalaxyl + mancozeb fungicide at 800 ppm concentration. The efficient photocatalytic activity of the biogenic IONPs against rhodamine B dye and their effective antifungal properties suggest their potential use as safe substitutes for commercial fungicides.
由于合成染料无法自然分解，它们在环境和水生生态中的积累是一个重大的环境问题。化学杀菌剂的过度使用也对环境造成了威胁，因为它们会累积并产生真菌抗药性。因此，本研究利用木槿花提取物制备了绿色合成氧化铁纳米粒子（IONPs），以检测其抗真菌特性和光催化活性。当浓度为 4.0 毫克/毫升时，生物源 IONPs 对罗丹明 B 染料的光催化活性最高。生物源 IONPs 还对数字青霉和黑曲霉菌株表现出有效的抗真菌特性，对菌丝生长的相对抑制率高于浓度为 800 ppm 的 metalaxyl + mancozeb 杀菌剂。生物源 IONPs 对罗丹明 B 染料的高效光催化活性及其有效的抗真菌特性表明，它们有可能成为安全的商用杀菌剂替代品。

Epibulbar dermoid, benign tumors resulting from the improper function of the pathogenic protein Patched 1 (PTCH1), surgical interventions are employed to mitigate the lethal effects. However, these procedures often lead to complications such as scleral weakening and corneal astigmatism. Due to the absence of effective medical treatments, there is a critical need for novel approaches to prevent the spread of this disease. This study not only fills a key gap in medical therapy for epibulbar dermoid, but it also demonstrates AI’s transformational potential in drug development. Employing an AI drug design service, three efficient de novo therapeutic compounds targeting the PTCH1 protein were crafted with Fisetin. The method included obtaining the PTCH1 protein sequence from NCBI, computing physiochemical parameters with Expasy Protparam, and estimating the 3D structure with SWISS-MODEL. Quality assessment, binding site prediction, drug design with WADDAICA, Lipinski’s Rule of 5, toxicity screening, ADMET evaluation, docking analysis with CB-dock and Patch dock, and MD simulations with IMOD all work together to provide an adequate basis for the development and validation of AI-designed phytochemical medicines for epibulbar dermoid. Comprehensive pharmacokinetic and toxicity assessments demonstrated the outstanding absorbency of AI-designed Fisetin in the blood–brain barrier, emphasizing its non-toxic nature. The AI-designed Fisetin exhibits a notable affinity of approximately −9.2 kcal/mol during docking with the PTCH1 protein, suggesting its potential as a drug. While the in silico results indicate efficiency and safety, the necessity for in vivo testing is acknowledged to validate these promising findings. This research significantly advances the frontier of knowledge by proposing a non-invasive solution to epibulbar dermoid, addressing current limitations, and offering potential alternatives to conventional surgical interventions.

The aim of this work was to improve the quality parameters, functional properties, and sensory attributes of the fino bread using sprouted whole wheat flour (SWWF) at different levels, i.e., 3, 6, and 9%. Results demonstrated that SWWF has two-fold phenolic compounds and antioxidant ability compared to unsprouted wheat. The SWWF was found to be high in protein, minerals, and fat while low in carbohydrates compared to the control sample. Additionally, the microbial loads of SWWF were within processing-acceptable limits. Dough stability and rheological attributes of wheat with SWWF were evaluated to predict the texture of the final bread. There was a positive correlation between stability time and mixed dough and texture parameters of wheat bread with SWWF. The bread made using SWWF was high in protein content. The panelists accepted the bread up to 9% SWWF addition from a sensory perspective. The findings demonstrated that SWWF might be suggested for utilization as an enhancer, particularly up to 9% addition in the bread-making industry.

Here we have shown the novel biosynthesis of silver nanoparticles (Ag NPs) encapsulated by chitosan polymers in the presence of Achillea millefolium aqueous extract (Ag NPs@CHI). The Ag ions were first embedded over the chitosan surface enriched with polar organofunctions like amines (NH2) and hydroxyls, and subsequently the ions were reduced green-metrically by the electron rich phytochemicals of the plant extract. After the synthesis numerous techniques, including the UV-vis spectrum, transmission electron microscopy, FE-SEM, EDS-elemental mapping, and ICP-AES, were used to study the physicochemical characteristics of the nanocomposite biomaterial. Next, we explored the material biologically in the anti-cutaneous squamous cell carcinoma effects against the corresponding cell lines like PM1, MET1, MET 4, SCC T9, SCC IC1MET, SCC IC19, SCC T8, and SCC T11. The related IC50 values of the nanocomposite against them were 182, 158, 177, 178, 177, 99, 62, and 183 µg/mL, respectively. The cytotoxicity in terms of percentage cell viability of cancer cells were decreased with the increase in the nanocomposite doses.

This research aimed to explore the protective and therapeutic properties of safranal in mitigating inflammation and oxidative stress induced by elevated acetaminophen (APAP) doses in a rat model. The protective and therapeutic effects of safranal were determined by histopathologically and examining some biochemical parameters such as aspartate transaminase (AST), alanine transaminase (ALT), glutathione, glutathione peroxidase, catalase, malondialdehyde, interleukin-6, tumor necrosis factor-α, and interleukin-1β. Male Wistar–Albino rats were subject to random allocation, forming five groups, each comprising seven rats (n = 7) in the study. Group 1 was the control group. APAP was administered in Group 2 to induce hepatotoxicity. Rats in Groups 3, 4, and 5 received intraperitoneal injections of safranal at doses of 0.025, 0.05, and 0.1 mL/kg/day for 14 days, respectively. On the 15th day, to induce APAP-induced hepatotoxicity, four groups (Groups 2, 3, 4, and 5) acquired a single intraperitoneal injection of 600 mg/kg APAP. The presence of APAP-induced hepatotoxic effect was proven by elevated AST and ALT levels, which are typical biomarkers of liver function in addition to the demonstration of histopathological changes. The findings suggest that pre-treatment with safranal may offer a protective effect against hepatotoxicity by attenuating oxidative stress and the inflammatory response.

Various analytical techniques were used to characterize the produced CuO-NPs. Transmission electron microscope investigation indicated well-distributed spherical particles in various development phases. The particles’ diameters ranged from 22.15 to 37.01 nm, with an average of 24.8 ± 6.1 nm. Energy dispersive X-ray examination confirmed the presence of nanoscale Cu ions at a high concentration, as seen by the strong signal peak at 1 keV. Fourier transform infrared spectrum revealed various functional groups on the green-produced CuO-NPs, as evidenced by multiple absorption beaks. The bands found at 3,195 and 2,916 cm−1 revealed that phenolic and flavonoid compounds’ alcohols and alkanes were stretching C–H. Also, a band at 1,034 cm−1 is typically attributed to CuO production. CuO-NPs exhibited significant bioactivity against isolated and molecularly identified fungal strains, including Rhizoctonia solani (OR116528), Fusarium oxysporum (OR116508), and Botrytis cinerea (OR116491). Remarkably, the highest inhibition percentages were recorded at 100 µg/mL, with values 81.48, 71.11, and 50.74% for R. solani, F. oxysporum, and B. cinerea, respectively. Molecular docking interactions revealed that the highest binding affinity of CuO-NPs was −5.1 for the oxidoreductase of B. cinerea and −5.2 and −5.4 for the chitin synthase of R. solani and F. oxysporum, respectively. Consequentially, the biosynthesized CuO-NPs could be employed as antifungal biocontrol agents, as well as using H. bacciferum leaf extract for the synthesis of nanoparticles for various sustainable agricultural applications.
在当前的研究中，生物合成氧化铜纳米颗粒（CuO-NPs）的方法是使用黑升麻叶提取物。研究人员使用了多种分析技术对所制备的 CuO-NPs 进行表征。透射电子显微镜研究表明，不同发育阶段的球形颗粒分布均匀。颗粒直径在 22.15 至 37.01 nm 之间，平均直径为 24.8 ± 6.1 nm。能量色散 X 射线检查证实了高浓度纳米级铜离子的存在，从 1 keV 处的强信号峰可见一斑。傅立叶变换红外光谱显示了绿色 CuO-NPs 上的各种官能团，多个吸收峰证明了这一点。在 3 195 和 2 916 cm-1 处发现的波段显示，酚类和黄酮类化合物的醇和烷烃正在伸展 C-H。此外，1,034 cm-1 处的条带通常归因于 CuO 的生成。CuO-NPs 对分离和分子鉴定的真菌菌株具有显著的生物活性，包括根瘤菌（OR116528）、镰刀菌（OR116508）和灰霉病菌（OR116491）。值得注意的是，在 100 µg/mL 浓度下，对 R.solani、F. oxysporum 和 B. cinerea 的抑制率最高，分别为 81.48%、71.11% 和 50.74%。分子对接相互作用显示，CuO-NPs 与 B. cinerea 的氧化还原酶的最高结合亲和力为-5.1，与 R. solani 和 F. oxysporum 的几丁质合成酶的结合亲和力分别为-5.2 和-5.4。因此，生物合成的 CuO-NPs 可用作抗真菌生物控制剂，也可利用 H. bacciferum 叶提取物合成纳米粒子，用于各种可持续农业应用。
