MedKoo Cat#: 407873 | Name: PQR530
Featured

Description:

WARNING: This product is for research use only, not for human or veterinary use.

PQR530 is a highly potent dual pan-PI3K/mTORC1/2 inhibitor. PQR530 inhibited protein kinase B (PKB, pSer473) and ribosomal protein S6 (pS6, pSer235/236) phosphorylation with IC50 values of 0.07 µM. PQR530 showed excellent selectivity over a wide panel of kinases, as well as excellent selectivity versus unrelated receptor enzymes and ion channels. Moreover, PQR530 displayed potency in a panel of 44 cancer cell lines (NTRC OncolinesTM) to prevent cancer cell growth (mean value for GI50 of 426 nM). Oral application of PQR530 to mice resulted in a dose-proportional PK and demonstrated good oral bioavailability and excellent brain penetration.

More Info
The PI3K/AKT/mTOR signaling pathway plays a fundamental role in cell proliferation, growth and survival and aberrant activation of this signaling pathway has been shown to drive the progression of malignant tumors. Drugs targeting the pathway at multiple points, such as dual PI3K/mTOR inhibitors appear to have the broadest activity profile to address cancer therapeutic strategies and are currently being explored in numerous clinical studies

Biological target:
PQR530 is a potent, ATP-competitive, orally bioavailable and brain-penetrant dual pan-PI3K/mTORC1/2 inhibitor, with a subnanomolar Kd toward PI3Kα and mTOR (0.84 and 0.33 nM, respectively).
In vitro activity:
Here, this study reports a structure-activity relationship study, which led to the discovery of a drug-like adenosine 5'-triphosphate-site PI3K/mTOR kinase inhibitor: (S)-4-(difluoromethyl)-5-(4-(3-methylmorpholino)-6-morpholino-1,3,5-triazin-2-yl)pyridin-2-amine (PQR530, compound 6), which qualifies as a clinical candidate due to its potency and specificity for PI3K and mTOR kinases, and its pharmacokinetic properties, including brain penetration. Compound 6 showed excellent selectivity over a wide panel of kinases and an excellent selectivity against unrelated receptor enzymes and ion channels. Moreover, compound 6 prevented cell growth in a cancer cell line panel. The preclinical in vivo characterization of compound 6 in an OVCAR-3 xenograft model demonstrated good oral bioavailability, excellent brain penetration, and efficacy. Initial toxicity studies in rats and dogs qualify 6 for further development as a therapeutic agent in oncology.
