摘要
The biosynthesis of pyralomicin la (1) was studied by feeding of C-13 and N-15 labeled compounds to the culture of Microtetraspora spiralis MI178-34F18. The result indicated that the benzopyranopyrrole unit of 1 was derived from two units of acetate, one unit of propionate and one unit of proline, and that the cyclitol unit of 1 was derived from glucose metabolites. And 4'-O-CH3 was derived from the S-CH3 group of methionine.
