Peptides 10-18 complement C3 Homo sapiens 55-58 12871936-7 2003 This variant efficiently mobilizes calcium in response to synthetic C3a agonist peptides, but not to native C3a. Peptides 80-88 complement C3 Homo sapiens 68-71 25982307-3 2015 Cp40, a second-generation compstatin analog in clinical development, is a 14 amino-acid cyclic peptide that selectively inhibits complement activation in humans and non-human primates by binding to C3 and C3b. Peptides 95-102 complement C3 Homo sapiens 205-208 1756717-12 1991 Phosphoamino acid analysis of the synthetic peptides indicated that serine 71 of C3a was phosphorylated by LPK-1. Peptides 44-52 complement C3 Homo sapiens 81-84 6139373-10 1983 A tryptic peptide containing the 3H label was isolated following digestion of [3H]C3b on activated thiol-Sepharose. Peptides 10-17 complement C3 Homo sapiens 82-85 1572104-2 1992 The biological activities of the anaphylatoxin C3a and synthetic C3a analogue peptides were determined in both assays. Peptides 78-86 complement C3 Homo sapiens 65-68 1466288-1 1992 The human saliva of normal subjects containing large amounts of basic carboxypeptidase produces decarboxylated non inflammatory peptides, for instance, kinins and anaphilotoxins C3a, C4a and C5a. Peptides 128-136 complement C3 Homo sapiens 178-181 3486674-3 1986 Longer synthetic C3a analogue peptides, e.g., C3a-57-77 containing the 21 COOH-terminal amino acids, exhibit activity nearly equivalent to that of intact C3a. Peptides 30-38 complement C3 Homo sapiens 17-20 3486674-3 1986 Longer synthetic C3a analogue peptides, e.g., C3a-57-77 containing the 21 COOH-terminal amino acids, exhibit activity nearly equivalent to that of intact C3a. Peptides 30-38 complement C3 Homo sapiens 46-49 3486674-3 1986 Longer synthetic C3a analogue peptides, e.g., C3a-57-77 containing the 21 COOH-terminal amino acids, exhibit activity nearly equivalent to that of intact C3a. Peptides 30-38 complement C3 Homo sapiens 46-49 6333413-4 1984 Studies reported here demonstrate that the spasmogenic action of C3a on guinea pig parenchymal lung tissue is mimicked by synthetic peptides based on the carboxy-terminal sequence of C3a. Peptides 132-140 complement C3 Homo sapiens 65-68 6333413-4 1984 Studies reported here demonstrate that the spasmogenic action of C3a on guinea pig parenchymal lung tissue is mimicked by synthetic peptides based on the carboxy-terminal sequence of C3a. Peptides 132-140 complement C3 Homo sapiens 183-186 6333413-5 1984 Synthetic peptides with sequences corresponding to the 5, 8, 13 and 21 carboxy-terminal residues of C3a all possess spasmogenic activity on lung tissue. Peptides 10-18 complement C3 Homo sapiens 100-103 6333413-8 1984 A 21 residue peptide, C3a 57-77, exhibits activity equivalent to native C3a. Peptides 13-20 complement C3 Homo sapiens 22-25 6333413-8 1984 A 21 residue peptide, C3a 57-77, exhibits activity equivalent to native C3a. Peptides 13-20 complement C3 Homo sapiens 72-75 266705-0 1977 Synthetic peptides with the biological activities and specificity of human C3a anaphylatoxin.
