p50RhoGAP or Cdc42GAP Assay | Inorganic phosphate produced as a result of GTPase activity was measured by using a p50RhoGAP or Cdc42GAP assay and absorbance-based detection method. Briefly, Cdc42 was preloaded with GTP or ZCL278 and incubated in the reaction buffer for 20 mins at 37 ℃. GAP was then added for an additional 20 mins at 37 ℃. Following a 10-min incubation in CytoPhos reagent, inorganic phosphate was detected at 650 nm. |
Cell lines | Cortical neurons |
Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20 ℃ for several months. |
Reaction Conditions | 50 μM; 5 and 10 mins or 2, 4, 6, 8 and 10 mins |
Applications | In ZCL278-treated neurons, neuronal branching was significantly suppressed over the time course. In addition, ZCL278 markedly inhibited Cdc42-mediated growth cone motility. |
产品描述 | ZCL278 is a selective inhibitor of Cdc42 with Kd value of 11.4 μM [1]. Cell division control protein 42 homolog (Cdc42) is a small GTPase that belongs to the Rho family and plays an important role in regulating diverse cellular functions including cell morphology, endocytosis, migration, and cell cycle progression [2]. ZCL278 is a potent Cdc42 inhibitor and has a different selectivity with the reported Cdc42 inhibitor ML141. When tested with human metastatic prostate cancer PC-3 cells, ZCL278 showed inhibitory function on Rac/Cdc42 phosphorylation and the function increasing as the more-treated time. In cortical neurons, ZCL278 treatment suppressed neuronal branch number and inhibited growth cone motility at the dose of 50 μM for 5 or 10 min. Treated serum-starved Swiss 3T3 fibroblasts Cdc42 activator following administration of ZCL278 at the dose of 50 μM for 1 h exhibited a significant decrease (nearly 80%) in GTP-Cdc42 and disrupted perinuclear distribution of active Cdc42. [1]. When tested with rat cerebellar granule neurons (CGNs), pre-treated with ZCL278 before exposed to NaAsO2 increased cell viability in a dose-dependent manner (20, 50 and 100μM) [3]. References: |
