    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.

    摘要: Fermentation of the microorganism Streptomyces sp. (MA6750) ATTC No. 55042 in the presence of the Angiotensin II (A II) receptor antagonist ##STR1## yields three analogs, each having a shikimate sugar-like moiety attached to the tetrazole, which are also A II antagonists useful in the treatment of hypertension and congestive heart failure and other indications known to respond to A II antagonists.
