Novel furano analogues of duocarmycin C1 and C2: design, synthesis, and biological evaluation of seco-iso-Cyclopropylfurano[2,3-e]indoline (seco-iso-CFI) and seco-Cyclopropyltetrahydrofurano[2,3-f]quinoline (seco-CFQ) analogues

compounds exhibited a high level of activity against selected solid tumors. At a concentration of 0.0084 microM (based on the IC(50) of compound 17 (seco-CBI-TMI) against the growth L1210 cells), while compounds 4 and 17 were toxic against murine bone marrow cells as judged by a colony forming study of freshly isolated murine progenitor hematopoeitic cells, compound 5, a seco-CFQ compound, was significantly
新型癸二酸-异-环丙基呋喃并[2,3-e]二氢吲哚(seco-iso-CFI)和癸二酸-环丙基四氢呋喃[2,3-f]喹啉(seco-CFQ)类似物的设计,合成和生物学评价描述了杜卡霉素。设计这些新颖的类似物(4-7),前提是呋喃氧原子上的孤对电子可以与由HCl损失形成的异环丙基呋喃并[e]吲哚酮(iso-CFI)烷基化部分偶联在化合物4-7中。通过使用氯乙烯的5-exo-trig芳基自由基环化的先验方法合成了seco-iso-CFI DNA烷基化药效团。在我们的研究中,除了形成顺式-异-CFI产物外,在自由基环化反应过程中还产生了等量的不可预期的顺式-CFQ产物。像CC-1065和adozelesin,使用Taq DNA聚合酶终止和热裂解分析,显示seco-iso-CFI化合物(4和6)和seco-CFQ化合物(5和7)优先使长片段小沟中的腺嘌呤-N3位置烷基化A残基。化合物6与DNA 1
