Synthesis and binary QSAR study of antitubercular quinolylhydrazides
摘要:
In continuation with our previous work in anti-TB research area, in the present study we have demonstrated the structural diversity of quinolylhydrazides as potent anti-tuberculars. The compound library was synthesized by molecular hybridization approach and tested in vitro against Mycobacterium tuberculosis H(37)Rv strains. Among the designed conjugates, the most promising molecules were found to exhibit 100% Growth Inhibition (GI) at MIC <6.25 mu g/mL. Moreover, several analogs in the designed series were also turned out as excellent anti-tuberculars. To probe the structural characteristics influencing on the SAR, the classification model was generated using a binary QSAR approach termed recursive partitioning (RP) analysis. The significant features outlined by the RP model act as a guide in order to design the 'lead' compound. (C) 2013 Elsevier Ltd. All rights reserved.

Two pairs of 1 : 2 nickel(ii) and copper(ii) metal-complex dyes showing the same trans configuration and azo–hydrazone transformation but different thermal properties
of 1 : 2 neutral trans mononuclear transition-metal (M = NiII and CuII) complexes of pyridine-2,4-dione and quinoline-2,4-dione based heterocyclic dyes have been structurally and spectrally characterized and compared herein. X-ray single-crystal diffraction analyses of four complexes, namely trans-[Ni(La)2(DMF)2] (1), trans-[Cu(La)2(DMF)2] (2), trans-[Ni(Lb)2(DMF)2] (3) and trans-[Cu(Lb)2(DMF)2] (4)
