General description

A cell-permeable, allosteric, trisubstituted dihydropyrazolyl compound that acts as a potent, selective, reversible and non-competitive inhibitor of Cdc42 GTPases (IC50 = 0.2, 2.6 and 5.4 µM against nucleotide depleted Cdc42-wt, Cdc42-wt and Cdc42 activated mutant, respectively) with excellent selectivity over Rho family GTPases (IC50 >100 µM for Ras-wt, Ras activated mutant, Rab7-wt, Rab2a-wt, Rac1-wt and Rac1 activated mutant). Shown to efficiently block Cdc42 association with GTPγS and PAK-PBD, and decrease GTP-Cdc42 (>95%) and GTP-Rac1 (≥40%) contents in EGF-stimulated 3T3 cells, and inhibit Bradykinin (Cat. No. 05-23-0500)-induced filopodia formation in 3T3 cells at 10 µM.

3D in vitro tumor models have recently been investigated as they can recapitulate key features in the tumor microenvironment. Reconstruction of a biomimetic scaffold is critical in these models. However, most current methods focus on modulating local properties, e.g. micro-

The number of neutrophils is significantly reduced in myelodysplastic syndrome (MDS), but the molecular basis remains unclear. We recently found that miR-34a was significantly increased in MDS neutrophils. Therefore, this study aims to clarify the effects of aberrant miR-34a expression

Previous studies showed that Cdc42, a member of the prototypical Rho family of small GTPases and a regulator of the actin cytoskeleton, is critical for the normal development and health of podocytes. However, upstream regulatory mechanisms for Cdc42 activity in
