一系列新颖的钌(II)配合物-cymene(1 - 8)含有取代的吡啶基噻唑配体,的[Ru(η 6 - p -cymene)(L)CL] CL(L = N,N-螯合衍生物),已经使用元素分析,红外,1 H NMR和13 C NMR光谱法和质谱法对这些化合物进行了合成和表征。所有这些复合物不仅在体外显示出明显的细胞毒性对三种不同的人类癌细胞系(HeLa,A549和MDA-MB-231)具有抗性,但在亚细胞毒性浓度下也显示出有希望的抗转移活性。细胞周期分析表明,钌(II)复合物诱导的生长抑制主要是由S期细胞周期停滞引起的。进一步的蛋白质水平分析表明,化合物5可能通过p53独立机制发挥抗肿瘤活性。

on a template approach. Structure-affinityrelationships revealed insights for extended knowledge of the receptor-ligand interaction. We replaced the bicyclic heterocyclic ring system of earlier described isoquinoline and quinazoline adenosine A(3) receptor ligands by several monocyclic rings and investigated the influence thereof on adenosine receptor affinity. The thiazole or thiadiazole derivatives

A series of compounds derived from the 2-amino-4-(2-pyridyl) thiazole scaffold was synthesized and tested for in vitro antimycobacterial activity against the Mycobacterium tuberculosis H37Rv strain, antiplasmodial activity against the chloroquine sensitive NF54 Plasmodium falciparum strain and cytotoxicity on a mammalian cell line. Optimal antimycobacterial activity was found with compounds with a 2-pyridyl ring at position 4 of the thiazole scaffold, a substituted phenyl ring at the 2-amino position, and an amide linker between the scaffold and the substituted phenyl. The antiplasmodial activity was best with compounds that had the phenyl ring substituted with hydrophobic electron withdrawing groups. (C) 2013 Elsevier Ltd. All rights reserved.
