  • Patent number: 9353133
    Abstract: This invention relates to compounds useful for treating fungal infections, more specifically topical treatment of onychomycosis and/or cutaneous fungal infections. This invention is directed to compounds that are active against fungi and have properties that allow the compound, when placed in contact with a patient, to reach the particular part of the skin, nail, hair, claw or hoof infected by the fungus. In particular the present compounds have physiochemical properties that facilitate penetration of the nail plate.

  • Patent number: 6653501
    Abstract: A method is provided for processing a solution having optical isomers to obtain a (2R,3S) target isomer: wherein P1 is H or a hydroxyl protecting group, R1 is H, an alkyl group, an olefinic group or an aromatic group, and R2 is H or R3CO, where R3 is an alkyl group, an olefinic group, an aromatic group, an O-alkyl group, an O-olefinic group or an O-aromatic group, provided that R1 is not H when R3 is Ph and P1 is H. The method includes passing the solution through a chromatographic stationary phase, such as S,S Whelk-O, that has a greater affinity for one of the target isomer and an optical isomer thereof. A portion of the solution with the target isomer is then collected. The solution may be a racemic mixture of (±)-N-CBZ-3-phenylisoserine ethyl ester.
