Class II HDACs, HDAC8 is one of the essential epigenetic players in cancer progression. Therefore, we designed, synthesized, purified, and structurally characterized novel compounds containing N-substituted TZD (P1-P25). Cell viability assay of all compounds on leukemic cell lines (CEM, K562, and KCL22) showed the cytotoxic potential of P8, P9, P10, P12, P19, and P25. In-vitro screening of different
表观遗传学在癌症进展中起着根本性的作用,而调节表观遗传学的开发剂对癌症的治疗至关重要。在I类和II类HDAC中,HDAC8是癌症进展中必不可少的表观遗传参与者之一。因此,我们设计,合成,纯化和结构表征了包含N-取代的TZD(P1-P25)的新型化合物。所有化合物在白血病细胞系(CEM,K562和KCL22)上的细胞活力分析均显示了P8,P9,P10,P12,P19和P25的细胞毒性潜力。体外筛选不同的HDAC亚型显示P19是HDAC8(IC50-9.3μM)的最有效和选择性抑制剂。热移分析(TSA)证实了P19与HDAC8的结合。体外筛选所有化合物对GLUT1,GLUT4,GLUT5表示P19抑制GLUT1(IC50-28.2μM)。P10和P19诱导CEM细胞凋亡(分别为55.19%和60.97%),并且P19对正常WBC(CC50-104.2μM)和人成纤维细胞(HS27)(CC50-105
