Purity:	≥98%
CAS#:	916232-21-8
Solubility:	DMSO up to 100 mM
Chemical Name:	4-(3-benzyl-4-((5-(2-fluorophenyl)furan-2-yl)methylene)-5-oxo-4,5-dihydro-1H-pyrazol-1-yl)benzoic acid
Storage:	Powder: 4^oC 1 year. DMSO: 4^oC 3 month; -20^oC 1 year.

Biological Activity:

GS143 is selective β-TrCP1 ligase inhibitor, inhibits IκBα ubiquitination with IC50 ~5.2 μM without affecting proteasome activity. It blocks LPS-induced expression of inflammatory cytokines in human myelomonocytic cells. It suppresses antigen-induced NFκB expression, inflammation and mucus production in airways of OVA-sensitized mice.

How to Use:

In vitro: GS143 was used at 10-20 μM final concentration in various assays.
In vivo: OVA-sensitized mice were given intranasally with GS143 (16 or 32 μg) and 2 h later, these mice were challenged with inhaled OVA.
