An experiment is conducted to determine the effect of magnetic water on the production performance and blood characteristics of common quail, Coturnix coturnix (Linnaeus, 1758). The experimental treatments included T1 = control treatment, T2 = drinking water magnetization at1000 gauss, T3 = drinking water magnetization at 1500 gauss, T4 = diet sprayed with magnetized water 1000 gauss, T5 = diet sprayed with magnetized water 1500 gauss, each treatment with three replicates. The results showed significant superiority of control group in the body weight, weight gain and feed intake compared with treated groups. The egg shell thickness of T2 showed a significant decrease compared to other groups. The third treatment showed a significant superiority in red blood cell count compared with T1, T4 and T5, while T5 appeared significant reduction in white blood cell count compared with other treatments. There was significant reduction in blood glucose, total protein, cholesterol, and triglyceride in T4 compared with control.

The development of anticancer compounds targeting the colchicine-binding site of tubulin, termed colchicine-binding site inhibitors (CBSIs) is a promising research area for pharmaceutical companies and research institutes. A series of 3,5-disubstituted 1,2,4-oxadiazoles, sharing common structural features with colchicine and combretastatins, was designed and synthesized for screening as antiproliferative CBSIs. All targets were submitted to National Cancer Institute (NCI), USA for screening at 10 mM in full NCI 60 cell panel. In addition, molecular docking studies were performed for the newly synthesized oxadiazole derivatives as CBSIs in β-tubulin against the β-tubulin pocket of colchicine. Also, 5a – as the most active member – was evaluated for its ability to inhibit β-tubulin polymerization against colchicine 6 as a reference standard. The targets showed significant antiproliferative activities. Amongst the series, target 5a demonstrated the broadest and most potent antiproliferative activity (positive cytotoxic effect (PCE) = 33/60 and the mean growth inhibition (MGI) for the most sensitive cell lines (33) is 24.9%. In addition, targets (5a–k) showed selective potency towards renal cancer in particular the A498 cell line. The order of potency of the three most potent targets and the standard colchicine (retrieved from NCI database) against A498 is: colchicine (GI = 84.5%) > 5a (GI = 78%) > 5d (GI = 51%) > 5f (32%). Compound 5a achieved superior binding affinity (−8.06 kcal mol−1) compared with that of colchicine 6 itself, which achieved (−7.40 kcal mol−1). Also, 5a showed a two-fold potent inhibitory activity of tubulin polymerization (IC50: 1.18 μM) compared with that of colchicine (IC50: 2.37 μM). Thus, target 5a represents a promising selective anticancer CBSI.

Three sets of isatin-based Schiff bases were synthesized utilizing the molecular hybridization approach. Some of the synthesized Schiff bases show significant to moderate antiproliferative properties against MCF7 (breast), HCT116 (colon), and PaCa2 (pancreatic) cancer cell lines with potency compared to reference drugs 5-fluorouracil (5-FU) and Sunitinib. Among all, compound 17 f (3-((1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino)-1-((1-(2-methoxyphenyl)-1H-1,2,3-triazol-4-yl)methyl)-5-methylindolin-2-one) exhibits promising antiproliferative properties against the MCF7 cancer cell line with 2.1-fold more potency than Sunitinib. However, among all the synthesized compounds, three (5-methylisatin derivatives) were the most effective against HCT116 in comparison to 5-FU. Compound 17 f exhibited the highest anti-angiogenic effect on the vasculature as it significantly reduced BV from 43 mm to 2 mm in comparison to 5.7 mm for Sunitinib and flow cytometry supports the arrest of the cell cycle at G1/S phases. In addition, compound 17 f also showed high VEGFR-2 inhibition properties against breast cancer cell lines. Robust 2D-QSAR studies supported the biological data.

Cisplatin (CP) is an effective chemotherapeutic agent for treatment of various types of cancer, however efforts are needed to reduce its toxic side effect. Previous studies revealed promising effect of peptides in decreasing CP induced nephrotoxicity. Herein, novel Met-based peptidomimetics were synthesized using N-acylbenzotriazole as acylating agent in high yield. Evaluation of renoprotective effect of the synthesized targets on CP treated kidney cell line (LLC-PK1) revealed that pretreatment with 1/3 IC50 of targets II, IIIa-g attenuated CP induced cell death where the IC50 of CP was raised from 3.28 µM to 9.25-41.1 µM. The most potent compounds IIIg, II and IIIb exhibited antioxidative stress in CP-treated LLC-PK1 cells as confirmed by raising GSH/GSSG ratio and SOD concentration as well as decreasing ROS and MDA. Additionally, in vivo experiments using Sprague Dawley rats showed renoprotective effect of IIIg against CP-induced nephrotoxicity as evidenced by improved results of renal function tests and attenuated CP-induced renal structural injury. Moreover, antioxidant activity of IIIg was demonstrated via its ability to reduce renal MDA level and up-regulate renal antioxidant element GSH level. Further, immunohistochemistry of renal specimens showed the ability of IIIg to restore CP-induced suppression of Nrf2. Interestingly, in vivo and in vitro studies demonstrated that IIIg had no effect on CP antiproliferative activity. An assessment of the ADMET properties revealed that targets IIIg, II and IIIb showed good drug-likeness in terms of their physicochemical, pharmacokinetic properties. The findings presented here showcase that IIIg is a promising renoprotective candidate with antioxidative stress potential.

Graphical abstract A series of quinolone-triazole conjugates synthesized as potential antiviral agents for SARS-CoV2. Some of the conjugates are more potent than the standards., At present therapeutic options for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) are very limited. We designed and synthesized three sets of small molecules using quinoline scaffolds. A series of quinoline conjugates (10a-l, 11a-c, and 12a-e) by incorporating 1,2,3-triazole were synthesized via a modified microwave-assisted click chemistry technique. Among the synthesized conjugates, 4-((1-(2-chlorophenyl)-1H-1,2,3-triazol-4-yl)methoxy)-6-fluoro-2-(trifluoromethyl)quinoline (10g) and 6-fluoro-4-(2-(1-(4-methoxyphenyl)-1H-1,2,3-triazol-4-yl)ethoxy)-2-(trifluoromethyl)quinoline (12c) show high potency against SARS-CoV-2. The selectivity index (SI) of compounds 10g and 12c also indicates the significant efficacy compared to the reference drugs.

A novel series of quinoline derivatives of combretastatin A-4 incorporating rigid hydrazone and a cyclic oxadiazole linkers were synthesized and have demonstrated potent tubulin polymerization inhibitory properties. Many of these novel derivatives have shown significant antiproliferative activities in the submicromolar range. The most potent compound, 19h, demonstrated superior IC50 values ranging from 0.02 to 0.04 &micro, M against four cancer cell lines while maintaining low cytotoxicity in MCF-10A non-cancer cells, thereby suggesting 19h&rsquo, s selectivity towards proliferating cancer cells. In addition to tubulin polymerization inhibition, 19h caused cell cycle arrest in MCF-7 cells at the G2/M phase and induced apoptosis. Collectively, these findings indicate that 19h holds potential for further investigation as a potent chemotherapeutic agent targeting tubulin.

The environmentally friendly synthesis, short reaction time, simple workup, high yields, mild conditions and free of racemization are the key advantages of this protocol.

In an attempt to counteract bacterial pathogenicity, a set of novel imidazolidine-2,4-dione and 2-thioxoimidazolidin-4-one derivatives was synthesized and evaluated as inhibitors of bacterial virulence. The new compounds were characterized and screened for their effects on the expression of virulence factors of Pseudomonas aeruginosa, including protease, hemolysin, and pyocyanin. Imidazolidine-2,4-diones 4c, 4j, and 12a showed complete inhibition of the protease enzyme, and they almost completely inhibited the production of hemolysin at 1/4 MIC (1/4 minimum inhibitory concentration; 1, 0.5, and 0.5 mg/ml, respectively). 2-Thioxoimidazolidin-4-one derivative 7a exhibited the best inhibitory activity (96.4%) against pyocyanin production at 1 mg/ml (1/4 MIC). A docking study was preformed to explore the potential binding interactions with quorum-sensing receptors (LasR and RhlR), which are responsible for the expression of virulence genes.

A series of new 2‐arylbenzimidazole‐N‐1 acetamido conjugates have been synthesized and characterized. Their antifungal activities were evaluated against fluconazole‐resistant C. albicans and A. fumigatus by the inhibition zone technique and were compared with the standard amphotericin B. Minimum inhibitory concentrations were determined for the most potent compounds, after preliminary structure‐activity analysis. Based upon these results a sub‐set of twelve ethylglycinyl ester conjugates bearing fluoro, chloro or bromo substituents on the 2‐phenyl moiety were examined for structure‐activity relationships using an agarose diffusion method employing a hypersensitive Sacharomyces cerevisiae strain. None of these compounds however showed significant activity at the concentrations tested. Single‐crystal X‐ray determinations were conducted on two of the newly synthesized compounds and were compared with DFT computational analysis.
