Two previously synthesized and two structurally novel thiazoline iron chelators are described. N4-Benzyl-N1,N8-bis[[2-(2-hydroxyphenyl)thiazolin-4-yl]carbonyl] homospermidine (5) proved to be the most potent antiproliferative and cytocidal compound in the series with in vitro IC50 values of 3 and 1 microM on L1210 and P388 murine cell lines. The N4-acetyl analogue 7 was considerably less active than
描述了两种先前合成的和两种结构新颖的噻唑啉铁螯合剂。N4-苄基-N1,N8-双[[2-(2-(2-羟基苯基)噻唑啉-4-基]羰基]高嘧啶(5)被证明是该系列中最有效的抗增殖和杀细胞化合物,其体外IC50值为3在L1210和P388鼠细胞系上为1 microM。N4-乙酰基类似物7的活性明显低于5,其IC50和细胞活力值与结构简单的噻唑啉2和3相似。通过将3和7的抗增殖活性传递到细胞悬液中,可以大大降低或消除它们的活性。与FeCl3的摩尔比为1:1的混合物,而活性5不受Fe(III)螯合的影响。不出所料 3诱导了100 microM的G1 / S细胞周期阻滞,与DNA合成的干扰一致,而10 microM 5则不影响L1210细胞周期的分布。ti化胸腺嘧啶核苷掺入研究证实,在浓度低于40 microM的条件下,有5种不能干扰DNA合成。碱性洗脱研究表明,在10 microM的浓度下5不会在体外
