标题 :Compositions and methods of treatment of sympathetically maintained pain
发明人：CAMPBELL JAMES N
权利人:ARCLON THERAPEUTICS INC
摘要:Sympathetically maintained pain is treated topically by administering to the site where sympathetically maintained pain is present an α-1-adrenergic antagonist, α-2-adrenergic agonist, or other drug that depletes or blocks synthesis of sympathetic norepinephrine, known collectively as sympatholytic agents. Chemical formulas for several sympatholytic agents are given.

标题 :Methods for forming saturated (hetero)cyclic borylated hydrocarbons and related compounds
发明人：SMITH III MILTON R; SHANNON TIMOTHY M; MALECZKA JR ROBERT E; FORNWALD RYAN M
权利人:UNIV MICHIGAN STATE
摘要:The disclosure relates to methods for forming at least partially saturated cyclic and heterocyclic borylated hydrocarbons, as well as related compounds, which can be precursor compounds in the synthesis of any of a variety of pharmaceutical or medicinal compounds with a desired structure and/or stereochemistry for drug synthesis or drug candidate evaluation. The methods generally include reduction of an unsaturated cyclic or heterocyclic borylated hydrocarbon having a boron-containing substituent at an sp 2 -carbon, where such reduction converts the sp 2 -carbon to an sp 3 -carbon at the point of attachment of the boron-containing substituent. The methods can exhibit a selectivity for syn-addition during reduction, which can provide stereospecific products, such as when the unsaturated cyclic or heterocyclic reactant is multiply substituted with boron groups and/or other functional groups.
