Design, synthesis and molecular docking of substituted 3-hydrazinyl-3-oxo-propanamides as anti-tubercular agents
摘要:
Based on the anti-mycobacterial activity of various acid hydrazides, a series of substituted 3-hydrazinyl-3-oxo-propanamides has been designed. The target compounds have been synthesized from diethylmalonate using substituted amines and hydrazine hydrate in ethanol. Computational studies and anti-tubercular activity screenings were undertaken to test their inhibitory effect on protein kinase PknB from Mycobacterium tuberculosis. Binding poses of the compounds were energetically favorable and showed good interactions with active site residues. Designed molecules obey the Lipinski's rule of 5 and gave moderate to good drug likeness score. Among the sixteen compounds (1-16) taken for in silico and in vitro studies, 3 compounds (11, 12 and 15) have shown good binding energies along with exhibiting good anti-tubercular activity and thus may be considered as a good inhibitors of PknB.

Michael addition of ethyl N-arylmalonamates to ethyl2-(ethoxymethylidene)-3-oxobutanoate in ethanol in the presence of triethylamine at room temperature afforded the corresponding adducts which underwent cyclization to diethyl 1-aryl-6-methyl-2-oxo-1,2-dihydropyridine-3,5-dicarboxylates in 17–65% yield. N-Alkylmalonamic acid esters failed to react with ethyl2-(ethoxymethylidene)-3-oxobutanoate under

A series of 3-(1H -imidazo[4,5- c ]pyridin-2-yl)-1,5-diarylpyridin-2(1H )-onederivatives were designed and synthesized as potential anticoagulant agents. The 1,5-diarylpyridin-2(1H )-ones, key intermediates of these anticoagulants, were synthesized by a simple reaction of 2-aryl vinamidinium salts with ethyl 3-oxo-3-(arylamino)propanoate derivatives. The prothrombin time in canine blood showed
设计并合成了一系列3-(1 H- 咪唑并[4,5- c ]吡啶-2-基)-1,5-二芳基吡啶-2(1 H )-一衍生物,作为潜在的抗凝剂。这些抗凝血剂的关键中间体1,5-二芳基吡啶2-2 (1 H )-是通过2-芳基乙烯基盐与3-氧代-3-(芳基氨基)丙酸乙酯衍生物的简单反应合成的。犬血中凝血酶原时间表明,其中的氨基和羟甲基衍生物具有明显的抗凝能力(PT = 17.07 s)。
