Stromelysin is secreted as an inactive zymogen that is activated in the extracellular space by cleavage of the His81-Phe82 bond with the release of the 81-amino acid propeptide domain. This segment contains a 12-amino acid sequence (MRKPRC75GVPDVG) that is highly conserved in all matrix metalloproteinases. Previous studies have shown that the hexapeptide,… (More)
The Asp-Pro sequence of the cyclic peptide Ac-HN-Tyr-Cys*-Asp-Pro-Cys*-OH (1) could be replaced with the achiral dipeptide mimetic 1-(2-aminoethyl)cyclpentylcarboxylic acid with retention of potent inhibition of the VCAM-VLA-4 interaction.
We have identified a series of low molecular weight (Mr < 500) N-acylphenylalanines that are effective inhibitors of the VCAM-VLA-4 interaction. Investigation of the SAR of the N-acyl moiety led to the identification of N-benzylpyroglutamyl derivatives as being particularly potent.
The tissue inhibitors of metalloproteinases (TIMPs) represent a family of naturally occurring protein inhibitors of stromelysin and other members of the family of matrix metalloproteinases. A series of peptides based on the N-terminal sequence of natural TIMP-1 was synthesized and assessed for inhibitory activity against purified human stromelysin.… (More)
Proliferative responses to the T-cell mitogen, Con A, were markedly suppressed in spleen cells isolated from rats 12-16 days following induction of adjuvant-induced arthritis (AA). These responses were only partially restored following removal of plastic-adherent cells (AC-depleted). Prophylactic treatment of AA rats with a novel anti-inflammatory… (More)
