Abstract:
A method for treating urinary incontinence, such as incontinence resulting from bladder detrusor muscle instability, using enantiomerically enriched (R,S)-glycopyrrolate. The method comprises administering a therapeutically effective amount of enantiomerically enriched (R,S)-glycopyrrolate, or a pharmaceutically acceptable salt thereof, substantially free of the (S,R)-glycopyrrolate enantiomer. Pharmaceutical compositions for the treatment of urinary incontinence comprising enantiomerically enriched (R,S)-glycopyrrolate, or a pharmaceutically acceptable salt thereof, and an acceptable carrier are also disclosed.

Abstract:
Methods and compositions are disclosed utilizing optically pure (-)-fotemustine for the treatment of various malignancies, while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of fotemustine.

Methods and compositions are disclosed utilizing optically pure (+)-fotemustine for the treatment of various malignancies, while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of fotemustine.
Abstract:
A method for treating urinary incontinence while avoiding concomitant liability of adverse effects associated with racemic oxybutynin is disclosed. The method comprises administering a therapeutically effective amount of (S)-oxybutynin, (S)-desethyloxybutynin or a pharmaceutically acceptable salt thereof, substantially free of the corresponding R enantiomer. Pharmaceutical compositions in the form of tablets and transdermal devices comprising (S)-oxybutynin or (S)-desethyloxybutynin and an acceptable carrier are also disclosed, as is a synthesis of desethyloxybutynin.
Abstract:
Methods and compositions are disclosed utilizing optically pure (-)-liarozole for the treatment of conditions supported by estrogen or caused by elevated estrogen levels such as estrogen-dependent breast cancer, gynecomastia, systemic lupus erythematosus and premature labor while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of liarozole. Methods and compositions are also disclosed utilizing optically pure (-)-liarozole for the treatment of conditions supported by or caused by elevated testosterone levels, such as hormone dependent prostate cancer. Further disclosed are methods and compositions utilizing pure (-)-liarozole in combination with retinoic acid for enhancing therapy with retinoic acid, such as in the treatment of neuroectodermal and neuroepithelial malignancies, including glioma, promyelocytic leukemia and hormone-independent prostate cancer.
Abstract:
Methods and compositions are disclosed utilizing optically pure (-)-zileuton for the treatment of asthma, rheumatoid arthritis and ulcerative colitis in humans while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of zileuton. (-)-Zileuton is an inhibitor of 5-lipoxygenase and is therefore useful in the treatment of other conditions related to elevated leukotriene levels. (-)-Zileuton is also an antioxidant and is therefore useful in treating or preventing atherosclerosis.
Abstract:
Methods and compositions are disclosed utilizing optically pure (+) pantoprazole for the treatment of ulcers in humans while substantially reducing the concomitant liability of adverse effects associated with the racemic mixture of pantoprazole. The optically pure (+) isomer is also useful for the treatment of gastroesophageal reflux. (+) Pantoprazole is an inhibitor of H release and is therefore useful in the treatment of other conditions related to gastric hypersecretion such as Zollinger-Ellison Syndrome.
Abstract:
A process for producing substantially pure R-ketoprofen by the enantioselective hydrolysis of racemic ketoprofen choline ester is disclosed. The process utilizes either intact Beauveria bassiana hyphae or an R-specific ester hydrolase isolated therefrom. The ester hydrolase has an approximate molecular weight of 17,800 daltons and an N-terminal sequence of Ala-Pro-Asp-W-Ile-Ile-Gln-Gly-Leu-Ser-Arg-Ala-X-Asp-Gly-Gln-Asp.
Abstract:
A process for enantioselectively converting an aldehyde, a bisulfite adduct of an aldehyde or a glycidate to a chiral carboxylic acid is disclosed. The process utilizes a microorganism or an enzyme preparation from a microorganism and is particularly useful for producing NSAIDs of the profen class from readily available precursors. Bacteria, yeasts and fungi are exemplified as capable of transforming precursors to profens.
