In the effort to develop novel quinoline derivatives for the treatment of liver cancer, we synthesized a series of N?-Substituted methylene-4-(quinoline-4-amino) benzoylhydrazides and evaluated their biological activities as anticancer agents. Compounds 5h and 5j were found to be the potent antiproliferative agents against HepG2 cell line with an IC50 value of 12.6 ¡À 0.1 muM and 27.3 ¡À 1.7 muM, respectively. The most effective compound 5h also exhibited potent cytotoxicity against SMMC-7721 and Huh7 cells with IC50 values of 9.6 ¡À 0.7 muM and 6.3 ¡À 0.2 muM, respectively. Inspiringly, both 5h and 5j exhibited lower cytotoxic property in normal cells than hepatic carcinoma cells. Compounds 5h and 5j could down-regulate mRNA level of c-Myc and expression level of c-Myc. Meanwhile, they decreased expression level of anti-apoptotic protein Bcl-2 and increased expression levels of pro-apoptotic protein Bax and cleaved PARP with reference to tubulin. So various assays including cell colony formation, cell cycle distribution, as well as cell apoptosis and migration were performed to understand their antitumor role. It was confirmed that 5h and 5j inhibited the growth of HepG2 cells due to their anti-survival effect, induction of cell cycle arrest and cell apoptosis, and inhibition of cell migration. These results demonstrated that 5h might be as potential lead compounds to develop anticancer agents for the treatment of hepatocellular carcinoma.

Mycobacterial transcriptional repressor EthR controls the expression of EthA, the bacterial monooxygenase activating ethionamide, and is thus largely responsible for the low sensitivity of the human pathogen Mycobacterium tuberculosis to this antibiotic. We recently reported structure-activity relationships of a series of 1,2,4-oxadiazole EthR inhibitors leading to the discovery of potent ethionamide boosters. Despite high metabolic stability, pharmacokinetic evaluation revealed poor mice exposure; therefore, a second phase of optimization was required. Herein a structure-property relationship study is reported according to the replacement of the two aromatic heterocycles: 2-thienyl and 1,2,4-oxadiazolyl moieties. This work was done using a combination of structure-based drug design and in vitro/ex vivo evaluations of ethionamide boosters on the targeted protein EthR and on the human pathogen Mycobacterium tuberculosis. Thanks to this process, we identified compound 42 (BDM41906), which displays improved efficacy in addition to high exposure to mice after oral administration.

(Chemical Equation Presented) 1,3-Dipolar reactions of thiazolium azomethine ylides to enantiopure cyclic and acyclic vinyl sulfoxides provide an efficient access to polyfunctionalized pyrrolo[2,1-b][1,3]thiazoles in a highly regio- and stereoselective manner. Regioselectivity can be inverted by modifying the position of the sulfinyl group at the double bond of the sulfinylfuranones. The sulfoxide is the main controller of the endo selectivity of these processes as well as of the pi-facial selectivity in reactions of (Z)-3-p- tolylsulfinylacrylonitriles. In contrast, the pi-facial selectivity in reactions of 5-alkoxy-3-p-tolylsulfinyl furan-2(5H)-ones is mainly controlled by the configuration at C-5, affording the anti adducts with respect to the alkoxy group as the major or exclusive adducts.

An efficient copper-catalyzed selective cross coupling of imidazo[1,2-a]pyridines with methyl hetarenes has been reported. This transformation opened a new route to synthesize the C-3 carbonyl imidazo[1,2-a]pyridine derivative, which is a common structural motif in natural products and pharmaceuticals. 18O-labeling experiments indicated that the oxygen source of products originated from O2.

Purpose: To evaluate the therapeutic potential of new bi-heterocycles containing a 1,3-thiazole and 1,3,4-oxadiazole in the skeleton against Alzheimer’s disease and diabetes, supported by in-silico study. Methods: The synthesis was initiated by the reaction of 4-methyl-1,3-thiazol-2-amine (1) with bromoacetyl bromide (2) in aqueous basic medium to obtain an electrophile,2-bromo-N-(4-methyl-1,3-thiazol-2-yl)acetamide (3). In parallel reactions, a series of carboxylic acids, 4a-r, were converted through a sequence of three steps, into respective 1,3,4-oxadiazole heterocyclic cores, 7a-r, to utilize as nucleophiles. Finally, the designed molecules, 8a-r, were synthesized by coupling 7a-r individually with 3 in an aprotic polar solvent. The structures of these bi-heterocycles were elucidated by infrared (IR), electron ionization-mass spectrometry (EI-MS), proton nuclear magnetic resonance (1H-NMR) and carbon nuclear magnetic resonance (13C-NMR). To evaluate their enzyme inhibitory potential, 8a-r were screened against acetylcholinesterase (AChE), but brine shrimp lethality bioassay. Results: The most active compound against AChE was 8l with half-maximal inhibitory concentration (IC50) of 17.25 ¡À 0.07 muM. Against BChE, the highest inhibitory effect was shown by 8k (56.23 ¡À 0.09 muM). Compound 8f (161.26 ¡À 0.23muM) was recognized as a fairly good inhibitor of urease. In view of its inhibition of alpha-glucosidase, 8o (57.35 ¡À 0.17muM) was considered a potential therapeutic agent. Conclusion: The results indicate that some of the synthesized products with low toxicity exhibit notable enzyme inhibitory activity against selected enzymes compared with the reference drug, and therefore, are of potential therapeutic interest.
