Chemical Structure
Ro 106-9920
- CAS No.: 62645-28-7
- Formula:C10H7N5OS
- Molecular Weight:245.26
IUPAC Name: 6-(phenylsulfinyl)tetrazolo[1,5-b]pyridazine
InChIKey: JFSXSNSCPNFCDM-UHFFFAOYSA-N
SMILES: O=S(C1=CC=CC=C1)C2=NN3N=NN=C3C=C2
Biological Activity: Ro 106-9920 is an orally active NF-κB inhibitor. Ro 106-9920 prevents ubiquitination of IκBα, blocks nuclear translocation of NF-κB, and inhibits NF-κB activation. Ro 106-9920 suppresses TNF-α-induced tissue factor expression and procoagulant activity, enhances TNF-α-mediated cytotoxicity against cancer cells, and eliminates the formation of neutrophil extracellular traps. Ro 106-9920 inhibits NLRP3 inflammasome activation, reduces inflammatory cytokine secretion, decreases myeloperoxidase activity, attenuates renal cell apoptosis, and improves renal function. Ro 106-9920 blocks ANG II (Angiotensin II human) (HY-13948)-induced nuclear localization of p65, internalization of AT1A receptor, colocalization of β-arrestin-2, and expression of COX-2, and alters the formation of β-arrestin endosomes. Ro 106-9920 can be used in research related to non-small cell lung cancer, acute kidney injury, diabetes mellitus, and osteoporosis[1][2][3][4][5][6].
