Nitrogen-containing Heterocycles from Metarhizium sp. SC0924 and Their Antifungal Activities against Peronophythora lichii
绿僵菌SC0924含氮杂环类代谢产物及其抗荔枝霜疫霉活性

Twelve nitrogen-containing heterocycles were isolated from the solid cultures of Metarhizium sp.SC0924.On the basis of spectral data,they were identified as cyclo-(Ala-Pro)(1),cyclo-(Pro-Tyr)(2),cyclo-(Val-Leu)(3),cyclo-(Leu-Ile)(4),adenine(5),adenosine(6),uracil(7),thymine(8),thymidine(9),4-acetyl-aminoimidazole(10),n-butyl pyroglumate(11),and lumichrome(12).Compounds 2 and 3 showed weak antifungal activities against Peronophythora litchii by the agar diffusion method with paper disks.
