thiazolidines and pyrimidin-4(3H)-ones, and we tested the whole library existing in our lab against human p300 and PCAF HAT enzymes. Some compounds (1x, 1c', 1d', 1i' and 2m) were more efficient than CPTH2 and CPTH6 in inhibiting the p300 HAT enzyme. When tested in human leukemia U937 and colon carcinoma HCT116 cells (100 μM, 30 h), 1x, 1i' and 2m gave higher (U937 cells) or similar (HCT116 cells) apoptosis
最近,我们描述了一些(噻唑-2-基)azo作为抗原生动物,抗真菌和抗MAO试剂以及Gcn5 HAT抑制剂。在这些最后的化合物中,CPTH2和CPTH6在细胞中显示出HAT抑制作用和广泛的抗癌特性。为了鉴定比两个原型更有效的HAT抑制剂,我们合成了几种新的(噻唑-2-基)azo酮,包括一些相关的噻唑烷和嘧啶4(3 H)-酮,并测试了我们现有的整个文库针对人p300和PCAF HAT酶的实验室。某些化合物(1x,1c ',1d ',1i '和2m)在抑制p300 HAT酶方面比CPTH2和CPTH6更有效。在人白血病U937和结肠癌HCT116细胞(100μM,30小时)中进行测试时,1x,1i '和2m产生的凋亡(U937细胞)或类似细胞(HCT116细胞)高于CPTH6,并且在诱导细胞分化方面比CPTH6更有效(U937细胞)。
