45 results about "Staurosporine" patented technology

Staurosporine (antibiotic AM-2282 or STS) is a natural product originally isolated in 1977 from the bacterium Streptomyces staurosporeus. It was the first of over 50 alkaloids to be isolated with this type of bis-indole chemical structure. The chemical structure of staurosporine was elucidated by X-ray analysis of a single crystal and the absolute stereochemical configuration by the same method in 1994.

Staurosporine preparation method

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.

Phylum porifera symbiosis streptomycete, method for producing staurosporine by fermenting phylum porifera symbiosis streptomycete and application of phylum porifera symbiosis streptomycete

The invention relates to phylum porifera symbiosis streptomycete SP6206, belonging to the field of phylum porifera symbiosis streptomycete fermentation. The preservation number of the phylum poriferasymbiosis streptomycete SP6206 is CCTCCM2017451. The invention also discloses a method for producing staurosporine by fermenting the phylum porifera symbiosis streptomycete SP6206, which comprises thefollowing steps: (1) culturing a seed solution of the SP6206; (2) inoculating the cultured seed solution of the SP6206 to a fermenting culture substrate, and carrying out fermented culture, thereby obtaining a fermentation solution; and (3) separating staurosporine from the fermentation solution. According to the phylum porifera symbiosis streptomycete SP6206, the highest yield of the staurosporine reaches 320mg/L and is greatly increased compared with that of the common wild streptomycete staurosporine in the prior art. The staurosporine can be used for preventing and treating the colletotrichum gloeosporioides of Chinese yams, the minimal inhibitory concentration of the staurosporine for preventing and treating the colletotrichum gloeosporioides of the Chinese yams is 8 microg/ml, and the minimal inhibitory concentration of the staurosporine is 1/4 that of the positive drug cycloheximide.
