deacetylases, we have designed and synthesized a series of novel hydroxamic acids incorporating indole moiety as a cap group (3a–l). Biological evaluation showed that these hydroxamic acids potently inhibited HDAC2 with IC50 values in submicromolar range and up to tenfold (compound 3j) better than that of SAHA (also known as suberoylanilide hydroxamic acid). In four human cancer cell lines [SW620 (colon), PC-3
在寻找针对组蛋白脱乙酰基酶的新型小分子时,我们设计并合成了一系列以吲哚部分为帽基的新型异羟肟酸(3a - 1)。生物学评估表明,这些异羟肟酸有效抑制HDAC2,IC 50值在亚微摩尔范围内,比SAHA(也称为辛二酰苯胺异羟肟酸)的IC 50值高十倍(化合物3j)。在四种人类癌细胞系中[SW620(结肠),PC-3(前列腺),AsPC-1(胰腺),NCI-H23(肺)],这些合成的化合物对几种化合物(3k,3l)被发现比SAHA的细胞毒性高12到77倍。对接实验表明该化合物在活性结合位点与HDAC2紧密结合,结合亲和力远高于SAHA。我们目前的结果表明,这些新型异羟肟酸作为抗癌剂具有进一步开发的潜力。
