ALK4290 (AKST4290) is a potent and orally actively CCR3 inhibitor, compound Example 2, with a Ki of 3.2 nM for hCCR3[1]. ALK4290 can be used for the research of neovascular age-related macular degeneration and Parkinsonism[2][3].
AG-13958 monohydrochloride is the HCl salt of AG-13958 --- a VEGFA inhibitor potentially for the treatment of age-related macular degeneration. Neovascular AMD, a subtype characterized by the growth of new, pathologic blood vessels, results in most of the cases of severe and rapid vision loss associated with AMD. A critical activator of angiogenesis in neovascular AMD is VEGF.
