Abstract

The present invention relates to a staurosporine preparation method, wherein a molecular formula of the staurosporine is C28H26N4O3, and the staurosporine is prepared through streptomyces scabiei var.xuchangensis CGMCC No.5213 fermentation. According to the present invention, streptomyces scabies fermentation is adopted to produce the staurosporine so as to provide a new way for staurosporine production; and the staurosporine produced from the streptomyces scabiei var.xuchangensis provides strong antagonism for a plurality of plant pathogenic fungi, provides a strong in vitro deactivation effect for TMV, and has development potential as an agricultural antibiotic.

Description

technical field [0001] The invention belongs to the technical field of compound synthesis, and mainly relates to a method for preparing staurosporine by using a fermentation method. Background technique [0002] Pesticide is an important and indispensable material to solve the world's food problem and ensure stable and high yield of crops. It is also an industry that can obtain huge economic and social benefits. However, problems such as environmental pollution, human and animal poisoning, and increased resistance of diseases and insect pests caused by chemical pesticide residues are becoming more and more serious. Vigorous research, development, production and application of biological pesticides have become a new trend in the development of the global agricultural industry. At present, countries around the world are taking practical steps to reduce the use of chemical pesticides. For example, the US Environmental Protection Agency has announced the cancellation of the regi...
