Abstract

Natriuretic peptides (NP) are a family of structurally related but genetically distinct hormones/paracrine factors that regulate blood volume, blood pressure, ventricular hypertrophy, pulmonary hypertension, fat metabolism, and long bone growth. In this work we present computational structural analysis of the three human NP in solution, the synthesis and preliminary biological assays of a short fragment of CNP, I(14)GSM(17), together with one small mimetic, GGSM. Synthetic peptides IGSM, GGSM, and full length CNP were preliminary tested for their ability to influence cell growth of three human osteosarcoma cell lines. Synthetic peptides were shown to successfully mimic the biological activity of the full length natural peptide: their effects, although different upon the cell types used, are in accordance with the current literature, designating a possible role for CNP, and its derivatives, in skeletogenesis.
