Definition
ChEBI: N-(7,8-dimethoxy-2,3-dihydroimidazo[1,2-c]quinazolin-5-yl)-3-pyridinecarboxamide is a member of quinazolines.
Biological Activity
pik-90 is a broad-spectrum pi3k inhibitors that inhibits pi3kα, pi3kγ and pi3kδ with ic50 values of 11, 18 and 58nm, respectively [1].studies showed that pik-90 induced increased levels of secreted ige at 1 μmol/l, while it inhibited ige production at doses of greater than 2 μmol/l [2]. pik-90 has been reported to block akt phosphorylation. pik-90 combined with the cdk2 inhibitor has been demonstrated to induce apoptosis in ln229 ptenwt cells. in addition, pik-90 combined with sirna against both cdk1 and cdk2 has shown to induce cell death, whereas pik-90 combined with sirna against cdk1 or cdk2 had no apoptotic effect [3].
