concentrations of 439 nM and 753.6 nM for S462 and SNF96.2 cells, respectively. SW106065 remains nontoxic to normally dividing Schwann cells or mouse embryonic fibroblasts.
SW106065 (Cpd21; 0.25-5 µM; 24 hours; sMPNST cells) treatment shows a decreased percentage of cells in S phase, and a corresponding increased percentage in G1/G0 and G2/M.
SW106065 (Cpd21; 0.25-5 µM; 24 hours; sMPNST cells) treatment decreases the levels of cyclin A2, cyclin B1, cyclin D1, cyclin E, cdk4, and cdk6. And increases levels of cdkn1a and cdkn2a mRNA were observed in a dose-dependent manner.
SW106065 (Cpd21; 0.25-5 µM; 24 hours; sMPNST cells) treatment decreases the levels of Cyclin D1 protein.
SW106065 (Cpd21) treatment significant increase in the percentage of apoptotic cells.
