Featured Products:

Herboxidiene | Spliceosome inhibitor

Herboxidiene (142861-00-5) is a novel polyketide fermentation product produced by Streptomyces chromofuscus, originally discovered by screening for herbicidal activity. Potent and selective inhibitor of spliceosome subunit SF3b.2 Specifically targets SAP155, a subunit of SF3b responsible for pre-mRNA splicing.3 Displays anti-angiogenic activity via down-regulation of VEGFR-2 and HIF-1α.4 Spliceosome inhibitors have attracted enormous attention due to their potential use in cancer treatment.5

YM-254890 | Gq inhibitor

YM-254890 (568580-02-9) is a novel Gαq/11 inhibitor.1 U46619-induced platelet aggregation is inhibited but phorbol ester- or ionophore-induced aggregation is not2 (IC50 = 0.1-0.2 μM)1. It blocks Pasteurella multocida toxin-mediated activation of Gαq.3 A highly useful new tool for studying Gαq/11-coupled receptor signaling and resulting cellular events.4

7-Cl-O-Nec1 | RIP1 inhibitor

7-Cl-O-Nec1 (852391-15-2) is a necrostatin-1 (Cat.# 10-1162) analogue with superior potency (IC50 = 206nM vs 494nM), selectivity and metabolic stability in blocking RIP1.1,2 7-Cl-O-Nec1 shows no off-target inhibition of indolamine-2,3-deoxygenase (IDO) in contrast to Necrostatin-1 (Nec-1).3,4 7-Cl-O-Nec1 showed higher activity in inhibiting necroptosis in Jurkat cells than Necrostatin-1 (EC50 = 210 nM vs. EC50 = 490 nM), no non-specific cytotoxicity at high concentrations (100 μM) and reasonable pharmacokinetic characteristics when used in mice.2 7-Cl-O-Nec1 is recommended for cellular and in vivo use over Necrostatin-1.5
