β¦ Synopsis
The recent report' that irradiation of phenazine in dilute phosphoric acid solution gives 1-hydroxyphenazine (10) prompts us to record our own observations on the photo-oxidation of phenazine and its derivatives by irradiation (Hanovia CVS 5COA lsmp) in the presence of air.
Ye confirm the conversion of phenazine' to 1-hydrozyphenazine (10) and alao that of the

This study describes the synthesis and some pharmacological properties of eight new analogues of arginine vasopressin (AVP) substituted at position 2 or 3 with cycloleucine (1-aminocyclopentane-1-carboxylic acid, Apc). All new peptides were tested for their pressor, antidiuretic and uterotonic in vi
