Storage
2 years -20 centigrade Powder; 2 weeks 4 centigrade in DMSO; 6 months -80 centigrade in DMSO.
Molecular Formula
C23H28N8O4
Chemical Name
5-Pyrimidinecarboxamide, 2-amino-N-[2,3-dihydro-7-methoxy-8-[3-(4-morpholinyl)propoxy]imidazo[1,2-c]quinazolin-5-yl]-
Solubility
DMSO 0.002 mg/mL; Water 0.002 mg/mL; Ethanol 0.01 mg/mL
In vitro
BAY 80-6946 is a phosphoinositide 3-kinase (PI3K) inhibitor with potential antineoplastic activity. BAY 86-9766 inhibits proliferation with IC50 of 147 nM in HuCCT-1 (KRASG12D ) and 137 nM in EGI-1 (KRASG12D ) cell lines.
In vivo
BAY 80-6946 is generally well tolerated through the MTD (maximum tolerated dose) of 0.8 mg/kg. PK (pharmacokinetics) results support weekly dosing. Grade 2/3 hyperglycemia in the first 24 hrs after receiving a dose is common at the MTD. PK, clinical SD and FDG-PET data are consistent with effective exposure and PI3K pathway inhibition.
