ilbene (1a) derivatives resulted in the efficient synthesis of tyrosine amide hydrochloride 9, two tyrosine amide phosphate prodrugs (3a and 6), and sodium aspartate amide 11. Two additional cancer cell growth inhibitors (14 and 16) were synthesized by employing peptide coupling between amine 1a and the Dap unit of dolastatin 10 (4a) to yield amide 14 followed by Dov-Val-Dil (15) to yield peptide 16
对3,4-亚甲二氧基-5,4'-二甲氧基-3'-氨基-Z-二苯乙烯(1a)衍生物的进一步构效关系(SAR)的探索导致酪氨酸酰胺盐酸盐9的有效合成,两种酪氨酸酰胺磷酸盐的合成前药(3a和6)以及天冬氨酸酰胺11。通过在胺1a和dolastatin 10的Dap单元(4a)之间进行肽偶联以合成酰胺14,然后生成Dov,合成了另外两种癌细胞生长抑制剂(14和16)。 -Val-Dil(15)产生肽16。后者代表二苯乙烯1a与强大的微管蛋白组装抑制剂dolastatin 10的des-Doe四肽单元的组合。检查了肽16与长春花和//的微管蛋白的潜在结合。或秋水仙碱区域,并发现其主要用作dolastatin 10的亲戚。酰胺14具有抗隐球菌和抗菌活性。
