Several series of compounds containing the 1,4-dioxo-2-butenyl moiety have been prepared as candidate cytotoxins, including the methyl N-arylmaleamates, methyl N-arylfumaramates, and N-arylmaleimides. In addition, the N-arylisomaleimides were synthesized which are the structural isomers of N-arylmaleimides. These compounds were evaluated against human Molt 4/C8 and CEM T-lymphocytes as well as murine
已制备了若干系列含有 1,4-二氧-2-丁烯基部分的化合物作为候选细胞毒素,包括N-芳基马来酸甲酯、N-芳基富马酸甲酯和N-芳基马来酰亚胺。此外,合成了N-芳基异马来酰亚胺,它是N-芳基马来酰亚胺的结构异构体。这些化合物针对人 Molt 4/C8 和 CEM T 淋巴细胞以及鼠 L1210 细胞进行了评估。N-芳基富马酸甲酯显示出最高的细胞毒性效力,尤其是甲基N-(3,4-二氯苯基)富马酸盐对 L1210 细胞的作用是马法兰的六倍,在 Molt 4/C8 试验中与该药物等效。通过使用模型苄基硫醇对代表性化合物进行硫醇化来证明所研究化合物的亲电性。甲基ñ - (3,4-二氯苯基)fumaramate和甲基ñ - (4-氯苯基)马来酰胺酸抑制人Ñ -myristoyltransferase,可能的分子靶标,在高微摩尔范围。QSAR 和分子建模揭示了许多分子的不同结构特征与细胞毒性效力之间的一些

Starting from maleanitic and maleamic acids, a facile general approach to kinetically controlled isomaleimides has been described for the first time using cyanuric chloride as a dehydrating agent with 85-98% yields. The effect of a variety of substituents present on the aromatic ring in amine and maleic anhydride moiety, on these kinetic/thermodynamic dehydration processes of anilic acids has been also described. Under the same set of reaction conditions the phthalanilic acid gave kinetically controlled product, isoplitalimide in 91% yield, while the corresponding succinanilic acid furnished the thermodynamically more stable succinimide in high yield.
