hexacyclic antiviral and anti-tumor acridine alkaloids such as dercitin, cyclodercitin and kuanoniamine led to the identification of the thiazo[5,4-b]acridine or the isomeric thiazolo[4,5-b]acridine nucleus as the putative pharmacophore. Synthetic approaches towards these tetracyclic ring systems and regiochemistry of the thiazole ring in cyclodehydration reactions are discussed.
五环和六环抗病毒和抗肿瘤a啶生物碱(如dercitin,cyclodercitin和kuanoniamine)的结构简化导致鉴定了噻唑并[5,4- b ] ac啶或异构体噻唑并[4,5- b ] ac啶核推定药效团。讨论了这些四环系统的合成方法以及噻唑环在环脱水反应中的区域化学。
