摘要:
This invention relates to novel biologically active polyene oxazoles of Formula (I), their pharmaceutically acceptable salts and derivatives, and to methods of obtaining them. One method for obtaining the compounds is by cultivation of Streptomyces sparsogenes NRRL 2940 or a mutant or variant thereof. The pharmaceutical composition comprising a compound of the invention is useful as a cytotoxic agent and for inhibiting the growth of cancer cells.
摘要:
Novel polyene polyketides, their pharmaceutically acceptable salts, prodrugs and derivatives have been found to have antibiotic activity. Formula (I) One method for obtaining the compounds is by cultivation of Amycolatopsis orientalis ATCC™ 43491 or a mutant or variant such as the strain IDAC-220604-1. Another method for obtaining the compounds is post-biosynthesis chemical modification of the compounds obtained by cultivation. Novel polynucleotide sequences and encoded proteins for the biosynthesis of the polyene polyketides are also presented.

This invention relates to a new class of polyene polyketides, their pharmaceutically acceptable salts and derivatives, and to methods for obtaining the compounds. One method of obtaining these compounds is by cultivation of novel strains of Streptomyces aizunensis; another method involves expression of biosynthetic pathway genes in transformed host cells. The present invention further relates to the novel strains of Streptomyces aizunensis used to produce these compounds, to the use of these compounds and their pharmaceutically acceptable salts and derivatives as pharmaceuticals, in particular to their use as inhibitors of fungal cell growth and cancer cell growth. The invention also relates to pharmaceutical compositions comprising these novel polyketides or a pharmaceutically acceptable salts or derivatives thereof. Finally, the invention relates to novel polynucleotide sequences and their encoded proteins, which are involved in the biosynthesis of these novel polyketides.
摘要:
The invention relates to a method and system for identifying a secondary metabolite synthesized by a target gene cluster within a microorganism. A putative or confirmed function is attributed to a gene within the gene cluster, and an extract from the microorganism is obtained which is suspected to contain the secondary metabolite synthesized by the gene cluster. The extract is then assessed for chemical, physical or biological properties, and the metabolite is identified and optionally isolated. Further, the invention provides a knowledge repository in which gene cluster information is linked to secondary metabolite production data. The invention further relates to a graphical user interface for accessing the knowledge repository, and a memory for storing data, having a data structure that is stored in the memory.
