Papyracillic acid (1), an antibiotic isolated from the ascomycete Lachnum papyraceum, owes its bioactivities to its reactivity towards nucleophiles. When reacted with cysteine and cysteine methyl ester, it exclusively added the thiol groups to the exomethylene double bond. Both papyracillic acid (1) and its analogue penicillic acid (2) react with pyridine to indolizine derivatives during acetylation
药草酸(Papyracillic acid)(1)是一种从子囊菌Lachnum papyraceum中分离出来的抗生素,其生物活性归因于其对亲核试剂的反应性。当与半胱氨酸和半胱氨酸甲酯反应时,它仅将硫醇基团添加到外亚甲基双键上。在乙酰化条件下,草吡咯酸(1)及其类似青霉酸(2)均与吡啶反应生成吲哚嗪衍生物。©1997爱思唯尔科学有限公司。
