摘要:
A thiol acid and esters thereof of formula (II): ##STR1## wherein R is hydrogen, a salt forming ion or a pharmaceutically acceptable ester-forming radical, have antibacterial and antimycoplasmal activity and are therefore useful in the treatment of human and veterinary bacterial and mycoplasmal infections.
摘要:
The present invention concerns the compounds having the formula (I), N-oxides, salt, stereoisomeric forms, racemic mixtures, prodrugs, esters and metabolites thereof, wherein Haryl is an aromatic monocyclic, bicyclic or tricyclic heterocycle having 3 to 14 ring members which contains one or more heteroatom ring members selected from nitrogen, oxygen and sulfur and which may optionally be substituted on (i) one or more carbon atoms by C1-6alkyl, halogen, hydroxy, optionally mono- or disubstituted amino, nitro, cyano, haloC1-6alkyl, carboxyl, C3-7cycloalkyl, optionally mono- or disubstituted aminocarbonyl, methylthio, methylsulfonyl, aryl, (R7a)n-M-R7b, Het1 and Het2; whereby the optional substituents on any amino function are independently selected from R5 and -A-R6; and on (ii) a nitrogen atom if present by hydroxy or -A-R6. It further relates to their use as broadspectrum HIV protease inhibitors, processes for their preparation as well as pharmaceutical compositions and diagnostic kits comprising them. It also concerns combinations thereof with another anti-retroviral agent, and to their use in assays as reference compounds or as reagents.
摘要:
The present invention provides a process for inversion of the absolute stereochemistry at the .alpha.-carbon atom of a C-6 substituent of a bicyclic carbapenem antibiotic via a phosphorus - azodicarboxylate mediated reaction. Novel azides, amines and formates are described as useful intermediates and as antibacterial agents.
