- Development of strategies for the site-specific in vivo incorporation of photoreactive amino acids: p-Azidophenylalanine, p-acetylphenylalanine and benzofuranylalanine
-
A major limitation of conventional site-directed mutagenesis is that substitutions are restricted to the 20 naturally occurring amino acids. While this problem can be circumvented in vitro to allow the site-specific incorporation of non-canonical amino acids, no similar in vivo methodologies yet exist. The main requirement for such a system is an aminoacyl-tRNA synthetase able to exclusively recognize a non-canonical amino acid and a suppressor tRNA. The engineering of such activities in aminoacyl-tRNA synthetases has proven to be problematic due to their high substrate specificity. Here we report progress towards the development of an antibody-based methodology to screen large mutant aminoacyl-tRNA synthetase libraries for specific recognition of the non-canonical photoreactive benzofuran amino acid [3-(5'-benzofuranyl)-alanine]. We also report the chemical synthesis and enantiomeric resolution of this amino acid. (C) 2000 Elsevier Science Ltd.

- The discovery and preparation of disubstituted novel amino-aryl-piperidine- based renin inhibitors
-
Recently, trans-disubstituted oxo-aryl-piperidines have been identified as small molecule nonpeptide renin inhibitors for the modulation of hypertension. Herein, we report on the discovery and preparation of a new class of novel cis-disubstituted amino-aryl-piperidines as a mixture of enantiomers that are potent in vitro renin inhibitors and also, possess in vivo antihypertensive activity in a double transgenic mouse model.
