Biocatalytic racemization of (hetero)aryl-aliphatic α- hydroxycarboxylic acids by Lactobacillus spp. proceeds via an oxidation-reduction sequence

The biocatalytic racemization of a range of (hetero)aryl- and (di)aryl-aliphatic α-hydroxycarboxylic acids has been achieved by using whole resting cells of Lactobacillus spp. The essentially mild (physiological) reaction conditions ensure the suppression of undesired side reactions, such as elimination, decomposition or condensation. Cofactor/inhibitor studies using a cell-free extract of Lactobacillus paracasei DSM 20207 reveal that the addition of redox cofactors (NAD+/NADH) leads to a distinct increase in the racemization rate, while strong inhibition is observed in the presence of Thio-NAD+, which suggests that the racemization proceeds by an oxidation-reduction sequence rather than involvement of a "racemase" enzyme.

Therapeutic substituted indole compounds and compositions thereof

The present invention is concerned with compounds of formula (I) STR1 wherein R, R1 and R2 are independently selected from hydrogen and C1-4 alkyl; R3 and R4 are independently selected from hydrogen, C1-6 alkyl (including cycloalkyl) and aryl (wherein the alkyl or aryl group, which latter includes benzyl, is optionally substituted by one or more atoms or groups independently selected from halogen, C1-4 alkyl and aryl), provided R3 benzyl or substituted benzyl when R4 =H; m is an integer of from 0 to 2; n is an integer of from 0 to 3; (W) is a group of formula (i), (ii), (iii), or (iv) STR2 wherein Y is selected from oxygen, methylene and >N--R5, where R5 is hydrogen, C1-4 alkyl, or benzyl, Z and Z' are independently selected from >C=O, >C=S and methylene, and the chiral center * in formula (i) or (ii) is in its (S) or (R) form or is a mixture thereof in any proportions; X is a group selected from aryl (including heteroaryl) xanthenyl dibenzofuranyl which group is optionally substituted; and salts and solvates thereof, the preparation of these compounds, pharmaceutical formulations containing them and their use in medicine, particularly in the treatment of migraine.
