This research reports the synthesis of new benzimidazole-derived N-acylhydrazones (NAH), their characterization using various spectroscopic methods, and in vitro evaluation as potent carbonic anhydrase-II inhibitors. Among the target compounds, few showed higher inhibition than the standard acetazolamide (IC50: 18.6 ± 0.43μM). Mol. docking was performed on the most active compounds, which revealed their binding interactions with the active site of the enzyme, thus supporting the exptl. findings.

Liu, Jun published the artcileNovel 2-Substituted 3-Hydroxy-1,6-dimethylpyridin-4(1H)-ones as Dual-Acting Biofilm Inhibitors of Pseudomonas aeruginosa, Application of 4-Methoxyphenylacetic acid, the main research area is hydroxy dimethylpyridinone synthesis drug design Pseudomonas aeruginosa biofilm inhibitor.

2-Heptyl-3-hydroxy-4(1H)-quinolone (PQS), a compound from P. aeruginosa, functions as both a quorum sensing (QS) regulator and a potent iron chelator to induce expression of pyoverdine and pyochelin which are involved in high-affinity iron transport systems. A potential dual-acting antibiofilm strategy requires mols. designed to interfere with iron uptake and the QS system of P. aeruginosa. A series of 2-substituted 3-hydroxy-1,6-dimethylpyridin-4-ones have been designed, synthesized, and tested as biofilm inhibitors of P. aeruginosa. One compound, N-((1,3,6-trimethyl-4-oxo-1,4-dihydropyridin-2-yl)methyl)hexanamide, I, exhibits 68.67% biofilm inhibitory activity at 20μM. Further mechanistic studies have confirmed that this compound not only inhibits the QS systems of P. aeruginosa but also acts as an iron chelator to compete strongly with pyoverdine, causing iron deficiency in bacteria. The pyoverdine receptor FpvA was revealed as the target of I by the Pvds mutant strain, fpvA-overexpressed strain, and in silico studies.

Luo, Guolin published the artcileDesign, synthesis and antitumor evaluation of novel 5-methylpyrazolo[1,5-a]pyrimidine derivatives as potential c-Met inhibitors, Product Details of C9H10O3, the main research area is methyl pyrazolopyrimidine preparation antitumor cMet kinase inhibitor docking SAR; Antitumor activity; Molecular docking; Pyrazolo[1,5-a]pyrimidine derivatives; Synthesis; c-Met kinase inhibitor.

A series of novel 5-methylpyrazolo[1,5-a]pyrimidine derivatives I (R = pyrazin-2-yl, 4-chlorophenyl, 2-fluorobenzyl, etc.; R1 = H, Me) were designed, synthesized, and evaluated for their in vitro inhibitory activities against c-Met kinase and antiproliferative activities against the SH-SY5Y, MDA-MB-231, A549, and HepG2 cell lines. Most of the compounds remarkably inhibited c-Met kinase and showed moderate to good cytotoxicity and selectivity toward the four cancer cell lines. Among them, compounds I (R = pyrazin-2-yl, 4-fluorophenyl; R1 = H) were the two most potent selective c-Met inhibitors with half-maximal inhibitory concentration (IC50) values of 5.17 ± 0.48 nM and 5.62 ± 0.78 nM, resp., and suppression abilities comparable with the pos. control cabozantinib. Cell proliferation assay further demonstrated that the two most promising compounds I (R = 3,5,6-trimethylpyrazin-2-yl, pyrazin-2-yl, ; R1 = H) also showed good cytotoxicity and selectivity toward MDA-MB-231 cells, with IC50 values of 26.67 ± 2.56μM and 26.83 ± 2.41μM, resp. Compounds I (R = 4-fluorophenyl, 4-methoxy-3-fluorophenyl; R1 = H) showed cytotoxicity and selectivity toward A549 cells, with IC50 values of 20.20 ± 2.04μM and 21.65 ± 1.58μM, resp. All antiproliferative activities were within the range of those of cabozantinib. Notably, these compounds I presented relatively low hepatotoxicity compared with reference drugs. Moreover, the preliminary structure-activity relationship and docking studies revealed that replacement of a nitrogen-containing heterocycle on the R (block A) group might improve the c-Met kinase inhibitory and antiproliferative effects in MDA-MB-231 cells, whereas displacement by a substituted benzene ring, especially for the p-fluorophenyl or 4-fluoro-3-methoxyphenyl moiety, on the R group enhanced cytotoxicity toward A549 cells. Together, these results suggest that I (R = pyrazin-2-yl, 4-fluorophenyl; R1 = H) are promising compounds and provide a basis for their development as new antitumor agents.

Li, Qing published the artcileSynthesis of (1,3,4-thiadiazol-2-yl)-acrylamide derivatives as potential antitumor agents against acute leukemia cells, Related Products of isoquinoline, the main research area is thiadiazole acrylamide preparation antitumor leukemia caspase dependent apoptosis; (1,3,4-thiadiazol-2-yl)-acrylamide; Acute leukemia; Antitumor agents; Cell apoptosis; Cytotoxicity.

A lead compound with the (1,3,4-thiadiazol-2-yl)-acrylamide scaffold was discovered to have significant cytotoxicity on several tumor cell lines in an inhouse cell-based screening. A total of 60 derivative compounds were then synthesized and tested in a CCK-8 cell viability assay. Some of them exhibited improved cytotoxic activities. The most potent compounds had IC50 values of 1-5μM on two acute leukemia tumor cell lines, i.e. RS4;11 and HL-60. Flow cytometry anal. of several active compounds and detection of caspase activation indicated that they induced caspase-dependent apoptosis. It was also encouraging to observe that these compounds did not have obvious cytotoxicity on normal cells, i.e. IC50 > 50μM on HEK-293T cells. Although the mol. targets of this class of compound are yet to be revealed, our current results suggest that this class of compound represents a new possibility for developing drug candidates against acute leukemia.

In the presence of a highly oxidizing acridinium tetrafluoroborate, aryl Me ethers and an aryl benzyl ether underwent chemoselective nucleophilic aromatic substitution reactions with cyanide generated in situ from acetone cyanohydrin and NaHCO3 in 1,2-dichloroethane/2,2,2-trifluoroethanol to yield aryl nitriles. The observed selectivities for nucleophilic aromatic substitution over direct cyanation correlated with the sites with the largest increases in pos. charge between the ethers and their radical cations; the transition state structures and activation barriers for cyanation of veratrole and Me 3,4-dimethoxybenzoate and cyanation kinetics and lack of linear free energy relationships were determined
