Calcitonin gene-related peptide (CGRP) has been implicated in the pathogenesis of migraine. Early chemistry leads suffered from modest potency, significant CYP3A4 inhibition, and poor aqueous solubility. Herein, we describe the optimization of these leads to give 4 (BMS-694153), a molecule with outstanding potency, a favorable predictive toxicology profile, and remarkable aqueous solubility. Compound 4 has good intranasal bioavailablity in rabbits and shows dose-dependent activity in validated in vivo and ex vivo migraine models.
Synthesis of regiospecifically substituted quinolines from anilines

A protocol for the synthesis of quinolines substituted on both pyridine and benzo-fused rings is reported. The method is based on the formylation of a substituted N-(tert-butoxycarbonyl)aniline followed by direct cyclisation and aromatisation of the inter
Chiral 5-(diphenylphosphanyl)-1,2,3,4-tetrahydroacridines: New N,P-ligands for asymmetric catalysis

Three chiral 5-(diphenylphosphanyl)-1,2,3,4-tetrahydroacridines, as first representative examples of a new class of chiral N,P-ligands were prepared from (+)-nopinone, (+)-camphor and 5α-androst-2-en-17-one. These ligands have been assessed in the enantioselective palladium-catalysed allylic substitution of 1,3-diphenylprop-2-enyl acetate with dimethyl malonate. Enantioselectivity up to 74% has been obtained.
