rb 3

RB-3, a PRC1 inhibitor, binds to RING1B-BMI1f with a Kd of 2.8 μM.

1. Schisandrol B (Besigomsin) may exert neuroprotective effects by attenuating the microglia-mediated neuroinflammatory response via inhibiting the TLR4-mediated NF-κB and MAPKs signaling pathways. 2. Schisandrol B has anti-inflammatory property, potentially result from the inhibition of COX-2, iNOS, IL-6, TNF-α and NO through the down-regulation of RIP2 and NF-κB activation. 3. Schisandrol B induces marked protective effects against hepatic and renal injury induced by CCl(4) exposure through differential regulation of the MAPK signal transduction pathway. 4. Schisandrol B significantly inhibits cell proliferation in a dose-dependent manner, due to cell cycle arrest in the G1 phase with the downregulation of cyclin D1 expression and Retinoblastoma (RB) phosphorylation.

Ginsenoside Rb3 (Gypenoside IV) is a natural triterpenoid saponin, exhibiting inhibition effect on TNFα-induced NF-κB transcriptional activity. It also inhibits the induction of COX-2 and iNOS mRNA.

Endothelin-3, human, mouse, rabbit, rat TFA is a 21-amino acid vasoactive peptide that specifically interacts with G-protein-linked transmembrane receptors [ET-RA and ET-RB].
