摘要:
Described is a process for producing a new FK-506 antagonist agent, a C-21 hydroxylated analog of FR-900520 under novel fermentation conditions utilizing the novel microorganism, Streptomyces hygroscopicus (Merck Culture Collection MA 6832) ATCC No. 55166. The macrolide antagonist is useful in preventing and/or counteracting accidental or inadvertent FK-506 overdosage in an FK-506 therapeutic program designed to prevent autoimmune diseases or human host rejection of foreign organ transplants, e.g. bone marrow, liver, lung, kidney and heart transplants.

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.
