| Description | CK-636(CK-0944636) is a small molecule inhibitor of Arp2/3 complex; Inhibitor of actin polymerization; Cell permeable inhibitor of human (IC50=4μM), fission yeast (IC50=24μM) and bovine (IC50=32μM) Arp2/3 complex between Arp2 and Arp3. Inhibits actin polymerization (IC50=22μM).
IC50 value: 4/24/32 uM (Human/fission yeast/bovine Arp2/3) [1]
Target: Arp2/3 complex; actin polymerization
CK-636 binds between Arp2 and Arp3, where it appears to block movement of Arp2 and Arp3 into their active conformation. CK-636 inserts into the hydrophobic core of Arp3 and alters its conformation. Both classes of compounds inhibit formation of actin filament comet tails by Listeria and podosomes by monocytes. References: | |||||

CK-636 is an Arp2/3 complex inhibitor with IC50 of 4 μM, 24 μM and 32 μM for inhibition of actin polymerization induced by human, fission yeast and bovine Arp2/3 complex, respectively [1].
The Arp2/3 complex is expected to be involved in morphogenesis and cell adhesion and is essential for epidermal function. It regulates tight junctions and terminal differentiation to promote epidermal barrier formation [2].
CK-636 binds between Arp2 and Arp3 where it appears to block movement of Arp2 and Arp3 into their active conformation and inhibits Arp2/3 complex’s ability to nucleate actin filaments. Using a Listeria motility assay to determine whether CK-636 can inhibit actin polymerization mediated by Arp2/3 complex in live cells. In a concentration dependence way, CK-636 reduced the formation of actin filament comet tails by Listeria with IC50 value of 22 μM in infected SKOV3 cells [1].

Actin-related protein 2/3 complex-based actin polymerization is critical for male fertility.[Pubmed:26223325]
Andrology. 2015 Sep;3(5):937-46.
The actin-related protein 2/3 (Arp2/3) complex is critical for regulation of actin polymerization, which is associated with sperm motility and capacitation status. However, the function of the Arp2/3 complex in male fertility has not yet been fully elucidated. Therefore, this study was designed to investigate the role of the Arp2/3 complex in different processes in spermatozoa and its consequences on fertilization and early embryonic development. In this in vitro study, mouse spermatozoa were incubated with different concentrations (10, 100, and 500 mum) of CK-636, an Arp2/3 complex antagonist. Our results demonstrated that inhibition of the Arp2/3 complex by high concentrations (100 and 500 mum) of CK-636 induced hyper-activated motility and acrosomal reaction, whereas intracellular calcium and tyrosine phosphorylation levels in spermatozoa were inhibited. Moreover, exposure of spermatozoa to the highest concentration of CK-636 reduced fertilization and embryo development. Interestingly, fertilization was significantly increased after treatment with 100 mum CK-636, whereas embryonic development was significantly decreased. Therefore, we conclude that the Arp2/3 complex plays a decisive role in regulation of sperm function and male fertility via actin polymerization. We anticipate that the Arp2/3 complex may have clinical application as marker for male fertility and male contraceptive targeting.
Migration of T cells on surfaces containing complex nanotopography.[Pubmed:24069255]
PLoS One. 2013 Sep 12;8(9):e73960.
T cells navigate complex microenvironments to initiate and modulate antigen-specific immune responses. While recent intravital microscopy study revealed that migration of T cells were guided by various tissue microstructures containing unique nanoscale topographical structures, the effects of complex nanotopographical structures on the migration of T cells have not been systematically studied. In this study, we fabricated surfaces containing nanoscale zigzag structures with various side lengths and turning angles using UV-assisted capillary force lithography and motility of T cells on zigzag patterned surfaces was studied. Motility of T cells was mostly affected by the turning angle, not by the side length, of the zigzag structures. In particular, motility behaviors of T cells near interfaces formed by turning points of zigzag patterns were significantly affected by turning angles. For obtuse turning angles, most of the T cells smoothly crossed the interfaces, but as the turning angle decreased, a substantial fraction of the T cells migrated along the interfaces. When the formation of lamellipodia, thin sheet-like structures typically generated at the leading edges of migrating cells by actin polymerization-driven membrane protrusion, was inhibited by an Arp2/3 inhibitor CK-636, a substantial fraction of T cells on those surfaces containing zigzag patterns with an acute turning angle were trapped at the interfaces formed by the turning points of the zigzag patterns. This result suggests that thin, wide lamellipodia at the leading edges of T cells play critical roles in motility of T cells in complex topographical microenvironments.
