A cell-permeable quinazoline derivative that blocks PMA/PHA-induced NF-kB activation in Jurkat cells (IC50=11nM), but has no effect on PKC kinase, and exhibits an anti-inflammatory effect on carrageenin-induced paw edema in rats (1mg/kg, i.p.). In addition, it is shown to inhibit the store-operated calcium entry (SOC) pathway possibly by targeting TRPC1 containing heteromeric channels in Huntington Disease (HD) neurons (SK-N-SH cells transfected with mutant Huntingtin Htt-138Q) at 300nM. It displays neuroprotective effects in YAC128 MSN mice neurons from glutamate toxicity dose-dependently from 30nM to 3uM, which is consistent with TRPC1 knocown effects, and attenuates the progressive decline in the climbing speed of the HD Drosophila, dose-dependently from 100uM to 400uM. Formula: C22H20N4O Molecular Weight: 356.4 Solubility: DMSO (100mg/ml clear, yellow solution) Storage and Stability: Lyophilized powder may be stored at -20C. Stable for 12 months at -20C.
