摘要:
Fermentation of the microorganism Streptomyces sp. (MA6750) ATCC No. 55042 in the presence of the Angiotensin II (A II) receptor antagonist of the following structure: ##STR1## yields an analog having a shikimate sugar-like moiety attached to the tetrazole, the said analog which is also an A II antagonist useful in the treatment of hypertension and congestive heart failure and other indications known to respond to A II angatonists.
摘要:
Incubation of 13.beta.-hydroxy ivermectin aglycone with a species of Bacillus subtilis or the incubation of 13-deoxy ivermectin aglycone with a mixed culture of a species of Bacillus subtilis and of Streptomyces griseus results in the production of 13-.beta. ivermectin monoglucopyranoside as the major product and of 5-.beta. ivermectin monoglucopyranoside as the minor product.
摘要:
Described is a process for producing an immunosuppressant, "demethimmunomycin" (L-683,7411) a C-31 demethylated analog of L-683,590 under fermentation conditions utilizing the microorganism, Actinoplanacete sp, (Merck Culture Collection MA 6559) ATCC No. 53771. The macrolide immunosuppressant is useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow 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.
