The role of methoxy group substitution in various positions in both the rings of chalcones on cytotoxicity profile was studied using various synthesized chalcones. The fluorine containing acetophenones when reacted with various methoxy-substituted benzaldehydes in the presence of 10&nbsp;% sodium hydroxide solution gave the functionalized chalcones. All the synthesized chalcones were confirmed by spectral techniques like FTIR, 1H NMR, 13C NMR, and HRMS studies. All the synthesized compounds were screened for their cytotoxicity against various cell lines. The promising compounds were analyzed for cell cycle analysis.

A series of indazol-2-yl(pyridin-4-yl)methanones, 4 were acquired from 2,6-bisbenzylidene cyclohexanones, 3 and anti-tubercular drug (isoniazid), and their anti-tubercular impacts were screened. Among the test compounds used against Mycobacterium tuberculosis H37 Ra cell line in the microplate alamar blue assay, the compounds 4g-j revealed moderate anti-tubercular activity with MIC 12.5 μg/mL, comparable to standard drugs (streptomycin, MIC, 6.25 μg/mL, pyrazinamide, isoniazid and ciprofloxacin with MICs of 3.125 μg/mL). © 2015 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.

An efficient copper-free Pd(OAc)2/Ruphos-catalyzed Sonogashira coupling of 1-chloroisoquinolines in the formation of 1-alkynyl-3-substituted isoquinolines

In the title molecule, C20H13N3S, the triazoloisoquinoline ring system is approximately planar, with an r.m.s. deviation of 0.045 Å and a maximum deviation of 0.090 (2) Å from the mean plane for the triazole ring C atom which is bonded to the thio-phene ring. The phenyl ring is twisted by 52.0 (1)° with respect to the mean plane of the triazoloisoquinoline ring system. The thio-phene ring is rotationally disordered by approximately 180° over two sites, the ratio of refined occupancies being 0.73 (1):0.27 (1).
