NSC 23766 trihydrochloride is an inhibitor of Rac1 activation.

NSC 23766 (100 μM) treatment effectively inhibits polar body emission in a dose-dependent manner. NSC 23766 (200 μM) increases the percentage of morphologically abnormal spindles of oocytes. In NSC 23766-treated oocytes, the p-MAPK protein expression is significantly decreased^[2]. NSC23766 (50 μM) plus 100 ng/mL Jagged1, GDF9 and BMP15, reduces the number of germLine cell cysts and increases the number of primordial follicles^[3]. NSC23766 significantly inhibits GTP-Rac1 activity and phosphorylation of Rac1-PAK, ERKs and p38 MAPK in the spinal dorsal horn neurons^[4].

NSC23766 (2.5 mg/kg/day, i.p.) significantly attenuates the onset of spontaneous diabetes in NOD mice, without significant effects on the growth (body weights) of the mice. NSC23766 significantly increases the expression of Rac1 and CHOP, a marker for ER-stress, in islets from NOD mice^[1].

Briefly, fresh spinal cord tissue of the lumbar enlargement is homogenised in the presence of protease and phosphatase inhibitors and lysed with buffer. After being centrifuged at 12,000× g for 5 min at 4°C, the supernatants are collected and incubated with PAK-PBD beads at 4°C on a rotator for 1 h and then the beads are pelleted through centrifugation at 5000× g for 3 min at 4°C. The resulting pellet is resuspended in LaemmLi buffer and boiled for 2 min. The bead samples are subjected to Western blot analysis. Total Rac1 in each sample is also determined by Western blot analysis.

Balb/c control and NOD mice are at 7 weeks of age and are divided into four groups (n=8/group). At 8 weeks of age two groups of experimental animals (Balb/c and NOD) receive NSC23766 (2.5 mg/kg/day, i.p./daily) and other two groups, which serve as control Balb/c and NOD mice and receive equal volume of saline. The body weights and blood glucose are monitored every week for 34 weeks.
