Electronic and vibrational optical activity of several peptides related to neurohypophyseal hormones: disulfide group conformation.

Electronic and vibrational optical activity of the set of neurohypophyseal hormones and their analogs was investigated to clarify the S-S bond solution conformation. The selected compounds include oxytocin (I), lysine vasopressin (II), arginine vasopressin (III), and their analogs (IV-IX), differing widely in their pharmacological properties. We have… CONTINUE READING
