of the bicyclic perhydrofuran core of malayamycin A and two equally active N-nucleoside analogues as fungicides were investigated. Two analogues 10 and 11, representing a THP-truncated and a bicyclic aza-variant, were synthesized and found to be inactive. Molecular dynamics studies on malayamycin A and analogues were performed to highlight the importance of properly orientating the urea and methyl ether
研究了官能团方向的重要性以及马拉雅霉素A和两个同等活性的N-核苷类似物作为杀真菌剂的双环全氢呋喃核的完整性。合成了代表THP截短和双环氮杂变体的两个类似物10和11,发现它们是无活性的。进行了关于马拉雅霉素A及其类似物的分子动力学研究,以突出正确定位尿素和甲基醚基团的重要性。
