The present invention is directed to synthetic cytoskeletal active compounds that are inhibitors of rho-associated protein kinase. The present invention is also directed to pharmaceutical compositions comprising such compounds and a pharmaceutically acceptable carrier. The invention is additionally directed to a method of preventing or treating diseases or conditions associated with cytoskeletal reorganization. In one embodiment of the invention, the method treats increased intraocular pressure, such as primary open-angle glaucoma. The method comprises administering to a subject a therapeutically effective amount of a cytoskeletal active compound of Formula I or Formula II, wherein said amount is effective to influence the actomyosin interactions, for example by leading to cellular relaxation and alterations in cell-substratum adhesions.
