Abstract

A novel plant growth regulator, pironetin was isolated from the culture broth of Streptomyces sp. NK10958. The structure of pironetin was determined to be (5R, 6R)-5-ethyl-5, 6-dihydro-6-[(E)-(2R, 3S, 4R, 5S)-2-hydroxy-4-methoxy-3, 5-dimethyl-7-nonenyl]-2H-pyran-2-one by FAB-MS, ¹H and ¹³C NMR, COSY, COLOC, DEPT, IR, X-ray crystallographic analyses and adapted MOSHER'S method.
