Synthesis and molecular modeling studies of 3-chloro-4-substituted-1-(8-hydroxy-quinolin-5-yl)-azetidin-2-ones as novel anti-filarial agents
摘要:
A series of 3-chloro-4-substituted-1-(8-hydroxy-quinolin-5-yl)-azetidin-2-ones were synthesized and evaluated for their in vitro anti-filarial activity. To pre-assess the anti-filarial behavior of synthesized compounds (Va-f) on a structural basis, automated docking studies were carried out with Molecular Design Suite (MDS v 3.5) into the active site of glutathione-S-transferase (GST) enzyme; scoring functions of these compounds at the active site of the GST enzyme were used for correlation with observed activity. Compounds V-e and V-f have shown good affinity for receptor GST, as well as in vitro anti-filarial potency. (C) 2010 Elsevier Ltd. All rights reserved.

Five newtetranuclearcomplexesbased on an 8-hydroxyquinoline Schiffbase derivative and the β-diketone coligand, [Ln4(acac)4L6(μ3-OH)2]·CH3CN·0.5CH2Cl2 (Ln = Gd (1), Tb (2), Dy (3), Ho (4) and Er (5); HL = 5-(benzylidene)amino-8-hydroxyquinoline; acac = acetylacetonate) have been synthesized, and structurally and magnetically characterized. Complexes 1–5 have similar tetranuclear structures. Each
