Synthesis and biological activity of new series of N-modified analogues of the N/OFQ(1–13)NH2 with aminophosphonate moiety
摘要:
New series of N-modified analogues of the N/OFQ(1-13)NH2 with aminophosphonate moiety have been synthesized and investigated for biological activity. These peptides were prepared by solid-phase peptide synthesis-Fmoc-strategy. The N/OFQ(1-13)NH2 analogues were tested for agonistic activity in vitro on electrically stimulated rat vas deferens smooth-muscle preparations isolated from Wistar albino rats. Our study has shown that the selectivity of the peptides containing 1-[(methoxyphosphono)methylamino]cycloalkanecarboxylic acids to the N-side of Phe is not changed-they remain selective agonists of NOP receptors. The derivative with the largest ring (NOC-6) demonstrated efficacy similar to that of N/OFQ(1-13)NH2, but in a 10-fold higher concentration. The agonistic activity of newly synthesized N-modified analogues of N/OFQ(1-13)NH2 with aminophosphonate moiety was investigated for the first time.
Novel N-(phosphonomethyl) glycine derivatives: Design, characterization and biological activity
摘要:
A series of C alpha,alpha-disubstituted cyclic derivatives of N-(phosphonomethyl) glycine have been synthesized and characterized. They exhibited moderate clastogenicity, low antiproliferative activity on mice bone marrow cells and well expressed cytotoxicity against human tumor cell lines. The 8- and 12-membered cyclic analogs proved superior to the remaining compounds and were found to trigger apoptotic cell death in DOHH-2 cells. The latter compound caused 50% inhibition of the viability of hemobastose-derived cell lines at concentrations ranging from 20 to 67 mu M. (c) 2007 Elsevier Masson SAS. All rights reserved.
