The chemical class of ACTL11 inhibitors encompasses a diverse range of compounds that primarily target the cytoskeletal network within cells. This network is essential for a multitude of cellular processes, including shape maintenance, intracellular transport, and cell division. The ACTL11 protein, being similar to actin, is likely involved in these processes. Consequently, chemicals that disrupt the cytoskeleton can indirectly affect the function of ACTL11. Compounds such as Cytochalasin D, Latrunculin A, and Swinholide A directly bind to actin or actin-related proteins, thus hindering the polymerization and stability of actin filaments. This can alter the structural integrity of the cytoskeleton, which in turn can interfere with ACTL11's interaction with actin. Jasplakinolide acts conversely, by stabilizing actin filaments, but the resultant disruption of normal cytoskeletal dynamics can also impact ACTL11's function.

Inhibitors like ML-7 and Y-27632 affect the phosphorylation states and activities of proteins that regulate the actin cytoskeleton, such as myosin light chain kinase and Rho-associated protein kinase (ROCK), respectively. By altering these regulatory mechanisms, these compounds can modify the cytoskeletal environment of ACTL11. Blebbistatin and CK-666, targeting myosin II and the Arp2/3 complex, respectively, can also influence the cytoskeletal architecture and thus ACTL11's role within it. Additionally, SMIFH2, which targets formin-mediated actin assembly, can have an impact on the organization of actin structures with which ACTL11 may associate. Lastly, microtubule-affecting agents like Colchicine, Nocodazole, and Paclitaxel, while primarily targeting tubulin dynamics, can create a cellular environment that indirectly affects ACTL11 by altering the interplay between microtubules and actin filaments.
