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:
Described is a new L-679,934 (FK-506) antagonist, L-686,292, a C-15, C-31 bisdemethylated, derivative of L-683,590, produced under fermentation conditions utilizing the microorganism, Actinoplanacete sp. (Merck Culture Collection MA 6559) ATCC No. 53771. The macrolide reverses the immunosuppressant action of L-679,934 (FK-506), and can be used diagnostically as a tool to determine the presence of FK-506 macrolide type immunosuppressants in natural product broths, distinguishing such immunosuppressants from other chemical families such as the cycloporins.

摘要:
Biotransformation products of a fermentation with culture MA7074 are potent HIV protease inhibitors. These products are useful in the prevention or treatment of infection by HIV and in the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
