    Abstract: Methods and compositions are disclosed utilizing the optically pure S(-) isomer of felodipine. This compound is a potent drug for the treatment of hypertension while avoiding the concomitant liability of adverse effects associated with the racemic mixture of felodipine. The S(-) isomer of felodipine is also useful for the treatment of angina and such other conditions as may be related to the activity of S(-) felodipine as a calcium channel antagonist such as cerebral ischemia, cerebral disorders, arrhythmias, cardiac hypertrophy, coronary vasospasm, myocardial infarction, renal impairment and acute renal failure, without the concomitant liability of adverse effects associated with the administration of the racemic mixture of felodipine.

    Abstract: A method for identifying, in vitro, distinct, drug-resistant, biologically-active mutants of a protein that may emerge in vivo in response to a drug targeted against the protein is disclosed. The method involves preparing, by heterologous expression of a library of nucleotide sequences, a complete library of mutant proteins accessible in a single generation. The mutant proteins from the library that are drug resistant are identified. When all the first generation mutants have been identified in the above manner, a combination of drugs can be identified that will block the development of resistance. The same technique allows evaluation of the ultimate clinical efficacy of a drug targeted against the protein by comparing the number of resistant first generation mutants. A preferred protein is an HIV protease.

    Abstract: A process for the preparation of taxol and derivatives of taxol ##STR1## is disclosed. The process involves reacting a .beta.-alkoxycarbonylamino-phenylpropionic acid with a 13-hydroxy taxane to produce an ester of the taxane at C-13; and then deprotecting the .beta.-alkoxycarbonylamino-phenylpropionic ester to produce a .beta.-amido-.alpha.-hydroxybenzenepropanoic ester of the taxane. Intermediates useful in the process are also disclosed.

    Abstract: Methods and compositions are disclosed utilizing the optically pure R(+) isomer of ondansetron. This compound is a potent drug for the treatment of nausea and vomiting associated with chemotherapy and radiation therapy, while avoiding the concomitant liability of adverse effects associated with the racemic mixture of ondansetron. The R(+) isomer of ondansetron is also useful for the treatment of behavioral disorders such as mood anxiety and schizophrenia, and such other conditions as may be related to R(+) ondansetron's activity as a competitive antagonist of serotonin receptor subtype 5-HT.sub.3 such as disorders of gastrointestinal motility, depression, migraine, and as an aid for alcohol withdrawal, nicotine withdrawal, and drug (benzodiazepine et al.) withdrawal, without the concomitant liability of adverse effects associated with the racemic mixture of ondansetron. Furthermore, the R(+) isomer of ondansetron is also useful for the treatment of cognitive disorders such as dementia or age-associated memory impairment, while avoiding the concomitant liability of adverse effects associated with the racemic mixture of ondansetron.
