CPYPP bound to DOCK2 DHR-2 domain (DOCK2DHR-2) in a reversible manner and inhibited its catalytic activity[1].
CPYPP inhibited the guanine nucleotide exchange factor (GEF) activity of DOCK2DHR-2 for Rac1 in a dose-dependent manner, with a half-maximal inhibitory concentration (IC50) of 22.8 ± 2.4 µM. This inhibitory activity was independent on length of preincubation time, ranging from 2 min to 30 min. In addition, CPYPP was nontoxic when applied to spleen cells or thymoma cells (BW5147α-β-) at 100 µM for 3 hr or 3 days, respectively [1]. Pre-treatment of human neutrophils with CPYPP, a small molecule inhibitor of the DHR-2 domain of DOCK proteins and thus of the Rac GEF activity of human DOCK2 and DOCK5, significantly impaired neutrophil chemotaxis and ROS production [2].
CPYPP effectively decreased the secretion and gene expression of TNF-α, IL-1β and IL-6 in the lungs, suggested effects of DOCK2 on endotoxemia-induced inflammatory responses in mice. CPYPP remarkably inhibited the infiltration of total cells, macrophages and neutrophils into the bronchoalveolar lavage fluid [3]. A reseach found out that a joint usage of both CPYPP and C25-140 revealed a better consequence compared to monotherapy against hepatic I/R injury [4].
