The alkylation of amines with either alcohols or carboxylic acids represents a mild and safe alternative to the use of genotoxic alkyl halides and sulfonate esters. Here we report two complementary one-pot systems in which the reductive aminase (RedAm) from Aspergillus oryzae is combined with either (i) a 1° alcohol/alcohol oxidase (AO) or (ii) carboxylic acid/carboxylic acid reductase (CAR) to affect
A pharmaceutical combination or composition containing a lipase inhibitor, preferably orlistat, and a bile acid sequestrant is useful for treating obesity.
A process for purifying alkenyl compounds having a divalent or trivalent heteroatom in the &agr;-position relative to the double bond by distillation comprises carrying out at least two distillations in which the purified alkenyl compounds are obtained from the gas phase by condensation, where the time between the first distillation after the synthesis of the alkenyl compounds and at least one further distillation is at least one day and the purified alkenyl compounds have an APHA color number of <30.
Disclosed herein are pharmaceutical compositions comprising wet granulated bile acid sequestrants having the general Formula I shown, and their process of preparation. The present invention also discloses process for preparation of Colesevelam hydrochloride, an antilipemic agent.
A method for treating a microbial infection in a mammal, such as a human, comprising treating the mammal with a therapeutically effective amount of a polymer comprising an amino group or an ammonium group attached to the polymer backbone via an aliphatic spacer group. The polymer can be a homopolymer or a copolymer. In one embodiment, the polymer is a copolymer comprising a monomer having a pendant ammonium group and a hydrophobic monomer.
