A series of thiazole-based inhibitorsselectivelytargetingDNA-bindingdomain of the androgenreceptor (AR) were synthesized and evaluated, and the SAR data were summarized. We identified a novel compound SKLB-C2807 that effectively inhibited the human prostate cancer cell line LNCaP/AR with the IC50 value of 0.38 μm without significant antiproliferative effects on other cell lines PC-3 (AR-negative)

has made PI3K a consensus target to inhibit as illustrated by more than 15 inhibitors now in clinical trials. Our previous work, built on the early pioneering multikinase inhibitor LY294002, resulted in the only PI3K vascular-targeted PI3K inhibitor prodrug, SF1126, which has now completed Phase I clinical trials. This inhibitor has properties that impart more in vivo activity than should be warranted
磷脂酰肌醇-3-激酶(PI3K)通路在多种肿瘤中的失调使PI3K成为抑制的共识靶标,目前临床试验中已使用15种以上的抑制剂进行了说明。我们先前的工作是建立在早期的首创的多激酶抑制剂LY294002的基础上的,导致了唯一的PI3K血管靶向PI3K抑制剂前药SF1126,该药物现已完成I期临床试验。该抑制剂具有比其酶促效力应赋予的更多的体内活性,该酶促效力通常远低于其他临床阶段的PI3K抑制剂。我们着手探索保留了这些特性并同时展现出对PI3K更高效力的支架。这项工作导致发现了5-morpholino-7 H -thieno [3,2- b] pyran-7-one系统作为潜在的PI3K抑制剂新化合物类别的基础,对PI3K具有增强的效力。这些化合物的合成和基于癌症干细胞的活性在本文中报道。

of amiloride. Reductions in lung metastases were demonstrated for two analogs in a late-stage experimental mouse metastasis model, and one analog completely inhibited formation of liver metastases in an orthotopic xenograft mouse model of pancreatic cancer. The results support further evaluation of 6-substituted HMA derivatives as uPA-targeting anticancer drugs.
the Bcl-2 family. Herein we describe the synthesis of obatoclax derivatives by replacement of the pyrrole and indole ring of obatoclax with thiophene, furan and thiazolidinedione. The in vitro cytotoxicity of the newly synthesized compounds is evaluated against hepatocellular carcinoma cells. Pyrrole and indole substituents of obatoclax analogues exhibited potent inhibition of cell growth. Among the tested
