analogues were tested against T. brucei rhodesiense STIB900 and L6 rat myoblast cells (for cytotoxicity) in vitro. Forty-four derivatives were more potent than 1, including eight with IC50 values below 100 nM. The most potent and most selective for the parasite was the urea analogue 2-(2-piperidin-1-ylamido)ethyl-4-(3-fluorophenyl)thiazole (70, IC50 = 9 nM, SI > 18,000). None of 33 compounds tested were able
2-(2-Benzamido)ethyl-4-phenylthiazole(1)是1035个分子(分为115个不同的支架)之一,被发现可抑制布氏锥虫(引起人类非洲锥虫病的病原体),浓度低于3.6μM,且非在由诺华研究基金会(GNF)的基因组学研究所进行的700,000种化合物库的表型高通量筛选中,对哺乳动物(Huh7)细胞具有毒性。在本实验室中,化合物1和72类似物是通过两种通用途径之一合成的。这些加10代市售的类似物进行了对所测试的T.布氏罗得西亚STIB900和体外大鼠L6成肌细胞(细胞毒性)。四十四个导数的强于一,其中八个IC 50值低于100 nM。对该寄生虫最有效和最具选择性的是尿素类似物2-(2-哌啶-1--1-基氨基)乙基-4-(3-氟苯基)噻唑(70,IC 50 = 9 nM,SI> 18,000)。测试的33种化合物中没有一种能够治愈被寄生虫感染的小鼠。但是,有7种化合
