A novel antifungal antibiotic, FR901469, was isolated from an unidentified fungus No. 11243. It is a water-soluble 40-membered macrocyclic lipopeptidolactone, consisting of D-Ala, L-Tyr, L-Val, trans-4OH-L-Pro, trans-3OH-L-Pro, threo-3OH-L-Gln, Gly, L-Orn, L-Thr, three residues of D-alloThr and a (3R)-hydroxypalmitic acid. Its structure, including absolute configurations, was unequivocally determined
从未知的真菌编号11243中分离出一种新型的抗真菌抗生素FR901469。它是一种水溶性40元大环脂肽内酯,由D-Ala,L-Tyr,L-Val,trans-4OH-L-Pro组成,反式-3OH-L-Pro,苏式-3OH-L-Gln,Gly,L-Orn,L-Thr,D-alloThr的三个残基和(3R)-羟基棕榈酸。根据化学和光谱学证据,其结构(包括绝对构型)明确确定为1。
