- Inhibiting neurotransmitter reuptake(United States Patent and Trademark Office, 2018-04-17)This document relates to compounds as well as methods and materials involved in modulating neurotransmitter reuptake. For example, compounds, methods for synthesizing compounds, and methods for inhibiting neurotransmitter reuptake are provided. Specifically gamma-amino alcohol derivatives that inhibit the reuptake of neurotransmitters such as dopamine, serotonin, epinephrine or norepinephrine are provided as therapeutic agents for the treatment of depression or anxiety in a mammalian subject.
- Method for the conversion of cephalomannine to taxol and for the preparation of n-acyl analogs of taxol(United States Patent and Trademark Office, 1995-11-28)The natural product cephalomannine can be converted to the important anticancer natural product taxol by a simple process involving the steps of dihydroxylation to give cephalomannine-diols, diol cleavage, benzoylation at the 2'-position and reaction with a 1,2-diamine. The same process when applied to mixtures of taxol and cephalomannine makes it possible to separate taxol from cephalomannine-diols by simple flash-chromatography after the dihydroxylation step. If the benzoylation step is avoided in the above sequence of conversions, the process leads to the free amine (N-debenzoyltaxol). In addition, the selection of an acylating reagent other than that with the benzoyl group for acylation of the free amine (N-debenzoyltaxol), allows the preparation of taxol analogs with other N-acyl substituents.
