Synthesis and evaluation of potent pyrrolidine H(3) antagonists.

The synthesis and biological evaluation of novel antagonists of the rat H(3) receptor are described. These compounds differ from prototypical H(3) antagonists in that they do not contain an imidazole moiety, but rather a substituted aminopyrrolidine moiety. A systematic modification of the substituents on the aminopyrrolidine ring was performed using pre-formatted precursor sets, where applicable, to afford several compounds with high affinity and selectivity for the H(3) receptor.

Standardization protocols and optimized precursor sets for the efficient application of automated parallel synthesis to lead optimization: a Mitsunobu example.

A strategy has been developed for the efficient application of automated parallel synthesis to specific aspects of the lead optimization processes employed in drug discovery. The method involves the synthesis of collections of compounds using sets of precursors designed to encompass established medicinal chemistry principles and that have been concurrently optimized with respect to a specific chemical transformation. The strategy is illustrated using an automated Mitsunobu protocol employing sets of aliphatic alcohols and phenols as precursors. The former has been formatted to perform simple alkyl homologation exercises, with the latter being designed for use in diversity-based studies.
