IC50: 200 nM
SB 290157 is a C3aR antagonist.
The anaphylatoxin C3a, a potent chemotactic peptide and inflammatory mediator, binds to and activates a G-protein-coupled receptor. Molecular cloning of the C3aR has facilitated the identification of the non-peptide C3aR antagonists.
In vitro: SB 290157 was a competitive antagonist of 125I-C3a and binding to rat basophilic leukemia (RBL)-2H3 cells expressing the human C3aR , with an IC50 of 200 nM. SB 290157 could also block the C3a-induced C3aR internalization concentration-dependently and C3a-induced Ca21 mobilization in RBL-C3aR cells and human neutrophils. SB 290157 was founf to be selective for the C3aR in that it did not antagonize the C5aR or six other chemotactic G protein-coupled receptors. In addition, SB 290157 could also inhibit C3a induced Ca21 mobilization of RBL-2H3 cells expressing the mouse and guinea pig C3aRs [1].
In vivo: In animal models, SB 290157 was able to inhibit neutrophil recruitment in a guinea pig LPS-induced airway neutrophilia model and decrease paw edema in a rat adjuvant-induced arthritis model [1].
Clinical trial: So far, no clinical study has been conducted.

师兄说每次一定要两块胶一起跑电泳才能形成回路,但是制胶因为只有一个制胶架,就只能分两次弄
想问一下一般都是这样的吗?还有加了浓缩胶插了梳子之后一定要等2h才能让胶充分凝固吗?
