  • Patent number: 6610866
    Abstract: A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.

  • Patent number: 5646316
    Abstract: The present invention relates to a bile acid derivative, which comprises a bile acid derivatized at the carboxyl group with a hydroxamic acid or hydroxamate ester. The carboxyl group in the bile acid compound can also be derivatized with an amino acid or oligopeptide, whose C-terminus is derivatized with a hydroxamic acid or a hydroxamate ester. The present invention also relates to a method of use of a bile acid or a bile acid derivative to inhibit a metalloproteinase enzyme, comprising contacting a metalloproteinase with an effective amount of a bile acid or bile acid derivative. In another embodiment, the present invention further relates to a method of use of a bile acid or bile acid derivative to therapeutically treat a disease, which is ameliorated by inhibiting a metalloproteinase enzyme. In this method, a therapeutically effective amount of a bile acid, a bile acid derivative or physiologically acceptable salts thereof, is administered to a human or other mammal.
