Biochem/physiol Actions

AT9283 has also been shown to accelerate growth arrest in various xenograft models.
AT9283 is an ATP site-targeting pyrazole-benzimidazole-based molecule with inhibitory potency against multiple kinases, most notably Aurora A/B (IC50 ≤3.0 nM), JAK2/3 (IC50 = 1.2/1.1 nM), Abl T315I (IC50 = 4 nM), GSK3β, FGFR2, VEGFR3 (Flt4), Mer, Ret, Rsk2/3, Tyk2, Yes (IC50 = 1-10 nM). AT9283 also inhibits 72 other kinases/mutations at a reduced potency (IC50 = 10-30 nM against 14, 30-100 nM against 21, 100-300 against 37 targets), while displaying an IC50 >300 nM toward 144 other kinase targets. AT9283 inhibits the growth/survival of multiple solid tumor cell lines in vitro (IC50 = 7.7-20 nM) and shows anti-cancer efficacy in mice via i.p. injection in vivo (67% and 76%HCT116 tumor growth inhibition on day 16, respectively, with 15 and 20 mg/kg b.i.d., two-day on and two-day off; >95% inhibition of Ba/F3 ETV6-JAK2 leukemia proliferation on day 12 with 10 mg/kg b.i.d. on days 2–5 and 8–12).

Constitutive activation of Janus kinase (Jak) 2 is the most prevalent pathogenic event observed in the myeloproliferative disorders (MPD), suggesting that inhibitors of Jak2 may prove valuable in their management. Inhibition of the Aurora kinases has also proven to be

Despite promising clinical results from imatinib mesylate and second-generation ABL tyrosine kinase inhibitors (TKIs) for most BCR-ABL(+) leukemia, BCR-ABL harboring the mutation of threonine 315 to isoleucine (BCR-ABL/T315I) is not targeted by any of these agents. We describe the in

The accumulation of unfolded proteins under endoplasmic reticulum (ER) stress leads to the activation of the multidomain protein sensor IRE1α as part of the unfolded protein response (UPR). Clustering of IRE1α lumenal domains in the presence of unfolded proteins promotes
