CIR inhibitors are a group of compounds that focus on modulating the activity or the influence of the Cytoplasmic inhibitor of R7, also known as CIR1. Since direct inhibitors are not extensively documented for this protein, the inhibitors listed above act indirectly by targeting associated pathways or cellular processes. Proteasome inhibitors like MG-132 can impact CIR1 by preventing the degradation of proteins it interacts with or modulating its stability.
Similarly, compounds like LY294002 and Wortmannin, which inhibit the phosphatidylinositol 3-kinase (PI3K), can modulate broader cellular processes and pathways that CIR1 might be a part of, given the PI3K's extensive involvement in cell survival, growth, and proliferation. Other inhibitors, like PD98059 and U0126, target the MEK-ERK pathway, affecting cell differentiation, proliferation, and survival. Additionally, broader kinase inhibitors, such as Staurosporine, offer a wide-ranging impact on cellular pathways, including any processes involving CIR1.
