Description

SBI-581 is an orally active and potent selective serine-threonine kinase TAO3 inhibitor, with an IC50 of 42 nM. SBI-581 promotes TKS5α accumulation at RAB11-positive vesicles. SBI-581 inhibits invadopodia formation. SBI-581 shows reasonable pharmacokinetics in mice using IP injection. SBI-581 shows antitumor activity[1].

SBI-581 shows moderate selectivity (> 5-10x) against the majority of a broad panel of kinases[1].

SBI-581 (10 mg/kg, IP, once) displays reasonable pharmacokinetics (t1/2=1.5 hr; AUC= 1202 hr*ng/mL; Cmax= ~2 μM)[1].
