The present invention relates to novel dihydropyrones with tethered heterocycles having improved pharmacologic properties which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The dihydropyrones are useful in the development of therapies for the treatment of viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of the dihydropyrones and intermediates useful in the preparation of the final compounds.

HIV protease inhibitors

This invention pertains to improved antiviral activity of 6,6-disubstituted-5,6-dihydropyran-2-ones caused by judicious placement of certain polar substituents at the 3 and/or 6 positions. The same substituents which enhance the cellular activity also diminish cytotoxicity further enhancing the desirable properties of these agents as antivirals.

Dihydropyrones with improved antiviral activity

Novel naphthyridine-, and quinolinecarboxylic acids as antibacterial agents are described as well as methods for their manufacture, formulation, and use in treating bacterial infections including the description of certain novel intermediates used in the manufacture of the antibacterial agents.

Antibacterial agents

The present invention relates to novel coumarin derivatives and related compounds which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The coumarin derivatives are useful in the development of therapies for the treatment of viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized coumarins and of related structures.

Coumarin derivatives as protease inhibitors and antiviral agents

Optically pure isomers of 7-[3-(1,1-dialkylmethyl-1-amino)-1-pyrrolidinyl]quinolones and naphthyridones as therapeutically active and safe antibacterial agents are described, as well as pharmaceutical compositions thereof, and a method of treating bacterial infections therewith. Also described is a method of manufacture of the quinolones and naphthyridones as well as the starting materials, the optically pure pyrrolidine moieties for attachment at the 7-position.

Optical isomers of

Optically pure R-enantiomer of alpha,alpha-dilower

Optically pure isomers of 7-[3-(1,1-dialkylmethyl-1-amino)-1 -pyrrolidinyl[quinolones and naphthyridones as therapeutically active and safe antibacterial agents are described, as well as pharmaceutical compositions thereof, and a method of treating bacterial infections therewith. Also described is a method of manufacture of the quinolones and naphthyridones as well as the starting materials, the optically pure pyrrolidine moieties for attachment at the 7-position.

Certain optically active substituted

A novel series of quinoline-, naphthyridine- and benzoxazine-carboxylic acids useful as antibacterial agents is described. Novel methods for preparing the compounds as well as novel intermediates are also described as are methods for their formulation and the use thereof in treating bacterial infections.

Certain optically active substituted 3-pyrraidine acetic acid

The novel series of quinoline-, naphthyridine- and benzoxazine-carboxylic acids useful as antibacterial agents is described. Novel methods for preparing the compounds as well as novel intermediates are also described as are methods for their formulation and the use thereof in treating bacterial infections.

Disubstituted 7-pyrrolidinoquinoline- and -napthylridine-3-carboxylic acids as antibacterial agents are described as well as methods for their manufacture, formulation, and use in treating bacterial infections.

Novel disubstituted-7-pyrrolidinoquinoline antibacterial agents

Novel, orally active antibacterial agents are described and characterized as 7-[[3-(aminomethyl)-3-alkyl]-1-pyrrolidinyl]-6-fluoro-1,4-dihydro-4-oxo -3-quinoline carboxylic acids or corresponding 1,8-naphthyridine derivatives as well as methods for their manufacture.
