abstract：:The biological activities of alpha-MSH des-acetyl MSH, gamma-MSH and LPH37-58 were compared using the Anolis rate method of bioassay. Dose-response data showed LPH37-58 to be equipotent with alpha-MSH, but des-acetyl MSH and gamma-MSH were found to be much less active. The effect of LPH37-58 was additive to that of al...
