BYL719(cas 1217486-61-7) is a potent and selective PI3Kα inhibitor with IC50 of 5 nM, liitle or no effect on PI3Kβ/γ/δ. BYL719 inhibits the proliferation of breast cancer cell lines harboring PIK3CA mutations, correlating with inhibition of various downstream signaling components of the PI3K/Akt pathway.
SB1317(TG-02) is a novel small molecule potent CDK2/JAK2/FLT3 inhibitor with IC50s of 13/73/56 nM respectively. TG02 is a novel pyrimidine-based multi-kinase inhibitor that inhibits CDKs 1, 2, 7 and 9 together with JAK2 and FLT3. It dose-dependently inhibits signaling pathways downstream of CDKs, JAK2 and FLT3 in cancer cells with the main targets being CDKs. TG02 is anti-proliferative in a broad range of tumor cell lines, inducing G1 cell cycle arrest and apoptosis. In vivo, TG02 exhibits favorable pharmacokinetics after oral dosing in xenograft models and accumulates in tumor tissues, inducing an effective blockade of both CDK and STAT signaling. TG02 induces tumor regression after oral dosing on both daily and intermittent schedules in a murine model of mutant-FLT3 leukemia (MV4-11) and prolongs survival in a disseminated AML model with wild-type FLT3 and JAK2 (HL-60). TG02 is active in various models of leukemia and provide a rationale for the ongoing clinical evaluation of TG02 i...
