Specific fluorogenic substrates for neprilysin (neutral endopeptidase, EC 3.4.24.11) which are highly resistant to serine- and metalloproteases
(Associação Brasileira de Divulgação Científica, 1997-10-01)
Two intramolecularly quenched fluorogenic peptides containing o-aminobenzoyl (Abz) and ethylenediamine 2,4-dinitrophenyl (EDDnp) groups at amino- and carboxyl-terminal amino acid residues, Abz-<!-- $MVD$:face(Times) ...
Vias metabólicas na degradação da bradicinina e influência de inibidores de cininases
(Universidade Federal de São Paulo (UNIFESP), 1997)
A contribuicao de diferentes atividades cininasicas no metabolismo da bradicinina na circulacao arterial foi avaliada na preparacao de leito vascular mesenterico de rato. Os peptideos bradicinina (BK1-9), BK1-8 e BK1-7 ...
A liver metalloendopeptidase which degrades the circulating hypotensive peptide hormones bradykinin and atrial natriuretic peptide
(Associação Brasileira de Divulgação Científica, 1999-01-01)
A new metalloendopeptidase was purified to apparent homogeneity from a homogenate of normal human liver using successive steps of chromatography on DEAE-cellulose, hydroxyapatite and Sephacryl S-200. The purified enzyme ...
Immune complexes (IC) down-regulate the basal and interferon-γ-induced expression of MHC class II on human monocytes
(Wiley Blackwell Publishing, Inc, 2001-08)
The interaction of Fc receptors for IgG (FcγRs) on monocytes/macrophages with immune complexes (IC) triggers regulatory and effector functions. Previous studies have shown that FcγR-IC interactions inhibit the IFN-γ-induced ...
Isolation and characterization of synergistic hemorrhagins from the venom of the snake Bothrops asper
(1993-09)
Three hemorrhagic factors (BaH1, BH2 and BH3) were isolated from the venom of Bothrops asper by gel filtration on Sephacryl S-200, DEAE-Sepharose chromatography, metal chelate affinity chromatography and hydrophobic ...
