The echinocandins represent the most recent class of antifungal drugs. Previous structure–activity relationship studies on these lipopeptides have relied mainly upon semisynthetic derivatives due to their complex chemical structures. A successful strategy for the rapid enantioselective synthesis of the branched fatty acid chain of caspofungin and analogues was developed to synthesize several simplified
棘球and素代表了最新的一类抗真菌药。先前有关这些脂肽的结构-活性关系研究由于其复杂的化学结构而主要依赖于半合成衍生物。快速成功地合成卡泊芬净的支链脂肪酸链和类似物的成功策略是合成几种卡泊芬净的简化类似物。确定每个模拟物对一组念珠菌菌株的比最小抑制活性。这种方法使人们能够获得新的全合成衍生的卡泊芬净模拟物,该模拟物对念珠菌具有高选择性的抗真菌活性。株。另外,数据表明羟基脯氨酸残基在大环肽环结构的生物活性构象中具有重要作用。
