Studies directed toward the design of orally active renin inhibitors. 1. Some factors influencing the absorption of small peptides
摘要:
A systematic evaluation of structure-absorption relationships using a high throughput intraduodenal rat screening model has led to the delineation of a set of structural parameters that appear to govern bioavailability in a series of peptide-based renin inhibitors. Optimum structures, exemplified by 25 and 41, incorporated a single, solubilizing substituent at the C- or N-terminus combined with a lipophilic P2-site residue. Both inhibitors gave unprecedented plasma drug levels upon intraduodenal administration to monkeys, and the calculated bioavailability for 41 (14 +/- 4%) is the highest reported for any peptidic renin inhibitor.

Totalsynthesis of the originally proposed structure of coibamide A, a highly N- and O-methylated cytotoxic marine cyclodepsipeptide, has been accomplished by using a [(4+1)+3+3]-peptide fragment-coupling strategy and careful examination and optimization of the multiple dense N-methylated amide-bond formations. The synthetic sample of the proposed coibamide A could not match the natural product in
