摘要:
The invention relates to processes for preparing compounds of the formula 1 and to pharmaceutically acceptable salts, prodrugs and solvates thereof, wherein R1, R3, R4, R6, R11, R13, R14, R15, R16, R17, k, l, and m are as defined herein. The compounds of formula 1 are useful intermediates toward preparing compounds that may be used in treating abnormal cell growth in mammals by administering pharmaceutical compositions.
摘要:
A new route for the preparation of substituted 1,5-naphthyridine-3-carboxyamides, useful in the diagnosis and treatment of anxiety, Downs Syndrome, sleep, cognitive and seizure disorders, and overdose with benzodiazepine drugs and for enhancement of alertness, is provided. These compounds may be readily prepared by heating the corresponding 1,5-naphthyridine-3-carboxylic acid ester with a primary amine in a polar solvent such as dimethylformamide or dimethylsulfoxide.
摘要:
The invention relates to processes for preparing compounds of formula 1 wherein R3 is as defined herein, and to pharmaceutically acceptable salts thereof, as well as intermediates useful in such processes. The compounds of formula 1 are antibacterial agents that may be used to treat various bacterial and protozoa infections. The invention also relates to pharmaceutical compositions containing compounds prepared by the processes of the invention and to methods of treating bacterial protozoa infections by administering such compounds.
