Antimicrobial Activity of Stereoisomers of Morinols A and B, Tetrahydropyran Sesquineolignans
摘要:
测试了吗啉醇 A 和 B 的所有立体异构体的抗菌活性。吗啉醇 A 和 B 的所有立体异构体都对交替孢霉具有抗真菌活性,尤其是 (-)- 吗啉醇 B 的活性最强。天然成分(+)-吗啉醇 A 和非天然立体异构体(7S,7′S,8R,8′R)-吗啉醇 B 对革兰氏阳性菌枯草杆菌和反硝化李斯特菌具有抗菌活性。
Determination of the Stereochemistry of the Tetrahydropyran Sesquineolignans Morinols A and B
摘要:
The 7',8'-stereochemistry of the tetrahydropyran sesquineolignans morinols A and B was determined as threo via synthetic studies and by comparison of NMR data of 7',8'-threo-morinol and 7',8'-erythro-morinol. This study also confirmed that the biosynthetic process produces enantiomeric mixtures of morinols A and B. This was ascertained by comparing the specific rotations of synthesized morinols A and B with those of naturally occurring morinols A and B.
