IL-17RC Inhibitors

IL-17RC inhibitors encompass a group of compounds that interfere with the signaling or expression of the IL-17 receptor C subunit (IL-17RC). This receptor is a critical component of the inflammatory response, and the inhibitors work by disrupting the processes that lead to its activation or expression. The chemical inhibitors operate through different mechanisms, such as blocking key kinases in the signaling pathway, inhibiting transcription factors like NF-kB, or by preventing the nuclear translocation of molecules that induce IL-17RC gene expression. Some of the inhibitors target the upstream kinase pathways, such as PIKfyve, IKK, and p38 MAPK, which are essential for activating the transcription factors that control IL-17RC expression. Others act by inhibiting proteasome function, which affects the stability and nuclear translocation of the NF-kB complex, directly impacting the receptor's expression levels.

Moreover, this class of inhibitors includes molecules that modify the activity of specific transcription factors involved in the IL-17RC signaling cascade. The transcription factor NF-kB, for example, is targeted by a number of these inhibitors in different ways. Some compounds prevent the phosphorylation and subsequent degradation of the inhibitor of kB (IkB), which sequesters NF-kB in the cytoplasm, while others directly block NF-kB's ability to translocate to the nucleus or bind DNA, thereby preventing the transcription of IL-17RC. STAT3, another transcription factor associated with IL-17 signaling, is also a target, with inhibitors like Stattic obstructing its phosphorylation and activation. These various modes of action contribute to the overall effect of suppressing IL-17RC-associated signaling pathways, impacting the protein's involvement in inflammatory processes.
