Condensation of 2-methylbenzoxazole with aromatic aldehydes bearing acidic protons. A convenient coupling in the synthesis of the HIV-reverse transcriptase inhibitor L-696,229
Novel aminopyridones inhibit HIV reverse transcriptase, and are useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in 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.

A new series of potent specific 2-pyridinonereversetranscriptase (RT) inhibitors was developed based on the preliminary development lead 3-[(phthalmido)ethyl]-5-ethyl-6-methylpyridin-2(1H)-one (3), a non-nucleoside derivative which exhibited weak antiviral activity in cell culture against HIV-1 strain IIIB. One compound, 3-[(benzoxazol-2-yl)ethyl]-5-ethyl-6-methylpyridin-2(1H)-one (9,L-696,229),
The combination of certain aminopyridones and anti-HIV nucleoside analogs has been found to synergistically inhibit HIV reverse transcriptase. This combination is useful in the prevention or treatment of infection by HIV and the treatment of AIDS, either as a combination of compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in further 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.
Incubation of ##STR1## with a preparation from mammalian organ yields as biotransformation product the compound 3-[2-(benzoxazol-2-yl)ethyl]-5-(1-hydroxyethyl)-6-methyl-2-(1H)-pyridinone . This product is useful in the prevention or treatment of infection by HIV and the treatment of AIDS.

Fermentation of the microorganism Actinoplanacete sp. (MA6559), ATTC No. 53771, in the presence of the HIV reverse transcriptase inhibitor ##STR1## yields 3-[2-(benzoxazol-2-yl)ethyl]-5-(1-hydroxyethyl)-6-methyl-2(1H)-pyridinone and 3-[2-(benzoxazol-2-yl)ethyl]-5-ethyl-6-hydroxymethyl-2(1H)-pyridinone, both of which are useful in the prevention or treatment of infection by HIV and the treatment of AIDS.
