【摘要】 从绿僵菌(Metarhizium sp. SC0924)固体发酵物中分离得到12个含氮杂环类化合物,通过波谱分析,分别鉴定为环(丙氨酸-脯氨酸)(1)、环(脯氨酸-酪氨酸)(2)、环(缬氨酸-亮氨酸)(3)、环(亮氨酸-异亮氨酸)(4)、腺嘌呤(5)、腺嘌呤核苷(6)、尿嘧啶(7)、胸腺嘧啶(8)、胸腺嘧啶脱氧核苷(9)、4-乙酰氨基咪唑(10)、焦谷氨酸正丁酯(11)和光敏素(12)。滤纸片琼脂扩散法试验表明化合物2和3具有较弱的抗荔枝霜疫霉活性。更多还原

【Abstract】 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.更多还原
