4-quinolinone metabolites were isolated fromPseudomonascepacia PC II, along with the known 2-(2-heptenyl)-3-methyl-4-quinolinone (HMQ) and 3-methyl-2-(2-nonenyl)-4-quinolinone, and their structures were established as 3-methyl-2-pentyl-4-quinolinone, 2-heptyl-3-methyl-4-quinolinone and 3-methyl-2-nonyl-4-quinolinone. HMQ showed antifungal and red pepper growthpromoting activities.
从洋葱假单胞菌 PC II 中分离出三种新的 4-喹啉酮代谢物,以及已知的 2-(2-heptenyl)-3-methyl-4-quinolinone (HMQ) 和 3-methyl-2-(2-nonenyl)-4 -喹啉酮,它们的结构被确定为 3-甲基-2-戊基-4-喹啉酮、2-庚基-3-甲基-4-喹啉酮和 3-甲基-2-壬基-4-喹啉酮。HMQ 显示出抗真菌和红辣椒生长促进活性。
