摘要:
The present invention is concerned with a novel biotransformation process for producing 17.beta.-N-monosubstituted carbamoyl-11-oxo-4-aza-5-.alpha.-androst-3-ones of the formula: ##STR1## These compounds are testosterone 5-.alpha. reductase inhibitors and are produced via a claimed novel biotransformation process using the green algae, Selenastrum capricornutum.
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.
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 process for selectively acylating FK-506 type immunosuppressant macrolides, including immunomycin (FK-520), in the C-32 position, under novel conditions utilizing an immobilized lipase enzyme, an acyl donor, and a dry, non hydroxylic organic solvent. The enzyme is absorbed onto a solid support and the enzyme/support catalyzes the C-32 acylation. The enzyme/support complex can then be filtered from the reaction mixture and, recycled for use.
摘要:
A dipeptide isostere is the biotransformed product after incubation with a culture of Streptomyces. It inhibits HIV protease, and is useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as a compound, pharmaceutically acceptable salt, pharmaceutical composition ingredient, whether or not as a prodrug or as a combination with other antivirals, anti-infectives, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.

摘要:
The present invention relates to novel compounds formed by metabolic conversion of compounds of structural formula (1), pharmaceutical compositions containing such compounds, and their use as &agr;v&bgr;3 integrin receptor antagonists. The compounds of the present invention are useful for inhibiting bone resorption, restenosis, angiogenesis, diabetic retinopathy, macular degeneration, inflammatory arthritis, cancer, and metastatic tumor growth. They are particularly useful for inhibiting bone resorption and for the treatment and prevention of osteoporosis.
摘要:
Described is a new immunosuppressant, L-683,519, a monodemethylated rearranged derivative of L-679,934, (FK-506) produced under fermentation conditions utilizing the microorganism, unidentified Actinomycete (Merck Culture Collection MA 6474) ATCC No. 53828. 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 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 MA6963) ATCC No. 55230. The macrolide immunosuppressant is useful in preventing human host rejection of foreign organ transplants, e.g. bone marrow, liver, lung, kidney and heart transplants.
