Título: | Peptide-biphenyl hybrids as calpain inhibitors |
Autor: | Montero, Ana CSIC; Mann, Enrique CSIC ORCID; Chana López, Antonio CSIC; Herradón García, Bernardo CSIC ORCID | Fecha de publicación: | 25-mar-2004 | Editor: | John Wiley & Sons | Citación: | Chemistry & Biodiversity 1(3): 442-457 (2004) | Resumen: | Calpain is a cysteine protease that is activated by Ca2+. The over-activation of calpain, which occurs on increasing Ca2+ concentration, causes a variety of diseases. This paper reports experimental results on the inhibition of calpain I (μ-calpain) by peptide-biphenyl hybrids. We have found that some peptide-biphenyl hybrids, with aromatic amino acids in the peptide chains, inhibit calpain with IC50 values in the nanomolar range. Since the peptide-biphenyl hybrids reported in the present paper do not posses a reactive electrophilic functionality, we hypothesize that they interfere with the activation of calpain by Ca2+, and present experimental and computational results on the binding of peptide-biphenyl hybrids to Ca2+. | Descripción: | 16 pages, 7 figures.-- PMID: 17191858 [PubMed].-- Taken in part from the Ph.D. thesis of A.
