## Abstract The study of 16, 17, 18, 19, 28, 29โhexahydrorifamycin S by ^1^HโNMR. spectroscopy using INDOR at 100 MHz and homodecoupling at 270 MHz has shown that the conformation of the ansa fragment C(20)โC(27) and the position of this fragment relative to the naphthoquinone chromophore are pract
## Abstract The ^1^Hโ and ^13^CโNMR. spectra of cycloโtetraglycyl show that the four peptide groups are magnetically equivalent, and different from either a standard __trans__ or a standard __cis__ peptide group. It is suggested that the observed NMR. features correspond to a nonโplanar form of the
## Synopsis We report the solid-phase synthesis and conformational analysis of a 14-membered, cyclic enkephalin analog, H-Tyr-~$-~-A,bu-Gly-Phe-~-Leu-] (where A,bu represents a,ydiaminobutyric acid). The results from the guinea pig ileum (GPI) and mouse vas deferens (MVD) assays show that the anal
