    摘要: Described is a process for producing a new immunosuppressant, a C-19/C-22 cyclic hemiketal (Compound I) biotransformation analog of FR-900520, under novel fermentation conditions utilizing the novel microorganism, Streptomyces sp. (Merck Culture Collection MA6969) ATCC No. 55280. The macrolide immunosuppressant is useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow, liver, lung, kidney and heart transplants.

    摘要: Described is a process for producing a new immunosuppressant, a C-31 desmethyl, C-19/C-22 cyclic hemiketal biotransformation analog (Compound I) of FR-900520, under novel fermentation conditions utilizing the novel microorganism, Streptomyces, lavendulae ATCC No. 55209. Also disclosed is the C-31 methylated derivative (Compound II) of Compound I produced by enzymatic methylation using 31-O-desmethylimmunomycin O-methyl transferase, (DIMT), a methyl transferase enzyme. The macrolide immunosuppressants are useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow, liver, lung, kidney and heart transplants.

    摘要: Described is a new microorganism, Actinoplanacete sp., (Merck Culture Collection MA 6559) ATCC No. 53771. The microorganism acts as a demethylating agent and can produce the new immunosuppressants, "demethomycin" (L-682,993) a C-31 demethylated analog of L-679,934, and "demethimmunomycin" (L-683,742) a C-31 demethylated analog of L-683,590, under novel fermentation conditions. These macrolide immunosuppressants are useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow and heart transplants.
