resistant-tuberculosis (MDR-TB) are urgently needed at this juncture to save the life of TB-infected patients. In this work, we have synthesized and characterized novel isatin hydrazones 4(a-o) and their thiomorpholine tethered analogues 5(a-o). All the synthesized compounds were initially screened for their anti-mycobacterial activity against the H37Rv strain of Mycobacterium tuberculosis (MTB) under level-I

The docking studies on CDK2 and GSK-3 beta inspired us to synthesis a series of indoline-2,3-dione hydrazones 10a-1. Treatment of indoline-2,3-dione derivatives 7a-d with hydrazine gave 3-hydrazonoindolin-2-ones 8a-d which were reacted with the appropriate aldehydes 9a-c to yield 3-substituted-(methylenehydrazono)indolin-2-ones 10a-1. Compounds 10a-1 showed a significant anticancer activity against human breast cell line MCF-7. Compounds 10c, f, i exhibited the highest activity almost the same of doxorubicin (IC50 = 6.10 mu M) with IC50 = 7.75, 6.75, 6.25 mu M, respectively. (C) 2014 Elsevier Masson SAS.

and C. neoformans) have been evaluated. All the compounds showed potent antibacterialactivity with IC50 ≈ 7.81 µM against H. influenza while the activity against fungal strains was less. Compounds a and c also had IC50 ≈ 7.81 µM against S. Pyogens. Furthermore, the results of total antioxidantactivity of hydrazone derivatives, expressed in terms of the ascorbic acid (mM) equivalents per mg of sample
在目前的研究中,通过靛红腙与醛基的缩合反应合成了五种靛红腙席夫碱连接的乙酰基支架。为了鉴定制备的腙衍生物的结构特征,进行了IR、1 H和13 C NMR光谱、元素分析和X射线晶体学。衍生物对六种细菌菌株(金黄色葡萄球菌、化脓性链球菌、大肠杆菌、霍乱弧菌、单核细胞增生李斯特菌和流感嗜血杆菌)和七种真菌菌株(光滑念珠菌、近平滑念珠菌、近平滑念珠菌、 C. krusei、C. albicans、C.tropicalis、C. keyfer 和 C. neoformans) 进行了评估。所有化合物均显示出有效的抗菌活性,IC 50 ≈ 7.81 µM 对流感嗜血杆菌,而对真菌菌株的活性较低。化合物 a 和 c对化脓性链球菌的IC 50 ≈ 7.81 µM 。此外,腙衍生物的总抗氧化活性的结果,以每毫克样品的抗坏血酸 (mM) 当量表示,表明它们具有优越的生物活性。这些研究表明,腙腙功能化的炔属衍生
