Asymmetric synthesis of phenanthroindolizidine alkaloids with hydroxyl group at the C14 position and evaluation of their antitumor activities
摘要:
The asymmetric total synthesis of the strongly cytotoxic phenanthroindolizidine alkaloid 3 was achieved. Using the same route, various derivatives were also synthesized. Cytotoxicity of those synthetic compounds was evaluated and compounds 19, 23, and 27 demonstrated potent cytotoxicities similar to that of 3. The in vivo antitumor efficacy of selected compounds was also evaluated and 23 demonstrated moderate antitumor efficacy. (C) 2010 Elsevier Ltd. All rights reserved.
New analogues of cryptopleurine with different aromatic methoxyl and chloro substituents have been synthesized. Intermediate isomeric 1-hydroxyphenanthro[9.10b]quinolizidines have been isolated and characterized. Yields in the Pschorr reaction have been improved by the novel use of sulphite ion. Some of the compounds have been found to have antifungal activity.
已经合成了具有不同的芳族甲氧基和氯取代基的隐叶嘌呤的新类似物。中间异构体1-羟基菲[9.10 b ]喹啉z已被分离和表征。通过新使用亚硫酸根离子可以提高Pschorr反应的收率。已经发现一些化合物具有抗真菌活性。
