These volumes present data on 1000 synthetic analogs of oxytocin and vasopressin in comprehensive tables, retrieivng data from many inaccessible sources. The accompanying text covers synthesis; physicochemical, biochemical, and pharmacological properties; enzymatic clearage; immunochemistry; and interactions with neurophysin and receptors. Relationships between chemical structure and biological activities are stressed. The set will be valuable to peptide chemists in particular, as well as to biochemists pharmacologists, and physicians and veterinarians.
