aryl/heteroaryl hydrazide based analogs merged with thioether moiety. The acrylamide based analogs showed significant hydrophobic interaction within binding pocket in addition to co-ordination with Zn+2 via carbonyl group, however the aryl/heteroaryl hydrazide based analogs showed binding towards Zn+2 via thiol moiety. Two classes (acrylamide and aryl/heteroaryl hydrazide based analogs) were synthesized to be
HDAC抑制剂的开发已成为针对不同类型癌症的最终需求。在计算机上通过支架跳跃策略将虚拟筛选应用于筛选新型支架,以开发不同的丙烯酰胺和与硫醚部分合并的基于芳基/杂芳基酰肼的类似物。基于丙烯酰胺的类似物除通过羰基与Zn +2配位外,在结合口袋中还表现出显着的疏水相互作用,但是基于芳基/杂芳基酰肼的类似物显示与Zn +2的结合通过硫醇部分。合成了两类(基于丙烯酰胺和基于芳基/杂芳基酰肼的类似物)与60个癌细胞系一起进行筛选,以揭示AHM-4和AHM-5均在90℃时对HL-60(白血病细胞系)显示出显着的抑制性生长。 GI 50分别为GI 50的0.37μM和0.42μM的2.87μM和3.20μM的MDA-MB-435(黑素瘤细胞系)细胞系。AHM-4和AHM-5对I类HDAC酶表现出一般的抑制特性,在IC 50时对HDAC 2具有不同的抑制活性与对照相比,除了通过实时PCR抑制I类HDAC酶表
