Compounds of formula I: ##STR1## wherein, ring C, A-B, R.sup.1, n, R.sup.2, and R.sup.3 have any of the meanings given in the specification, and their pharmaceutically acceptable salts are useful in the treatment of urinary incontinence. Also disclosed are pharmaceutical compositions, processes for preparing the compounds of formula I and intermediates.
摘要:
Compounds of formula ##STR1## where R.sup.1 and R.sup.2 are independently hydrogen or optionally-substituted C.sub.1-4 alkyl or aryl, or R.sup.1 and R.sup.2 are joined together to form a monocyclic or bicyclic ring system, are HIV protease inhibitors. These compounds are useful in the 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 treating infection by HIV are also described.
