Spirocitromycetin, an antiosteoporotic polyketide bearing a unique spirocycle, was characterized from a human mucus sputum-derived Penicillium velutinum. Its structure and absolute configuration were elucidated spectrally, with its biosynthetic pathway likely mediated via polivione, a reported heptaketide. Spirocitromycetin was shown to be antiosteoporotic at 0.1 μM in the prednisolone-induced osteoporotic
Spirocitromycetin 是一种具有独特螺旋环的抗骨质疏松聚酮化合物,其特征在于源自人类粘液痰的Penicillium velutinum 。它的结构和绝对构型被光谱阐明,其生物合成途径可能通过 polivione 介导,一种已报道的七肽。在泼尼松龙诱导的骨质疏松斑马鱼模型中,Spirocitromycetin 在 0.1 μM 时显示出抗骨质疏松作用。螺菌素变体合成和生物测定的组合已确定 5'-methyl-3' H -spiro[chromane-3,2'-furan]-3',4-dione 是一种未报道的抗骨质疏松药效团。总的来说,这项工作提供了新的起始(子)结构,可能对抗骨质疏松药物的发现具有重要意义。
