features of geiparvarin (1) that account for its cytostatic activity in vitro, a series of geiparvarin analogues (4a-g) modified in the 3(2H)-furanone moiety have been designed and synthesized. The preparation of 4a-g was achieved through a new approach to the 3(2H)-furanone ring based on the elaboration of isoxazole derivatives. Among these synthetic analogues, 4b, the 5-methyl-5-ethyl derivative, proved
为了尝试确定geeparvarin(1)在体外具有细胞抑制活性的某些结构特征,已设计并合成了在3(2H)-呋喃酮部分修饰的一系列geiparvarin类似物(4a-g)。4a-g的制备是通过基于异恶唑衍生物的精细合成的3(2H)-呋喃酮环实现的。在这些合成类似物中,5b(5-甲基-5-乙基)衍生物在体外抑制鼠和人肿瘤细胞系的增殖中具有1的活性。通常,在1的3(2H)-呋喃酮部分的C5原子处取代会略微降低geiparvarin的细胞抑制活性。这项研究中描述的几种吉巴伐林类似物(即5-甲基-5-乙基衍生物4b,3(2H)-呋喃胺4c,5-甲基衍生物4f,
