SGK Inhibitors

SGK Inhibitors form a specialized chemical class of compounds designed to selectively target and modulate the activity of SGK, or Serum and Glucocorticoid-regulated Kinase. SGK is a serine/threonine protein kinase that belongs to the AGC kinase family and shares structural and functional similarities with other kinases like AKT and protein kinase C. Structurally, SGK possesses a kinase domain responsible for its catalytic activity and regulatory domains that control its activation. SGK is an essential regulator of various cellular processes, including ion transport, cell proliferation, and cell survival, and is a key player in intracellular signaling pathways.One of the primary functions of SGK is its involvement in the regulation of ion transport across cell membranes. SGK can phosphorylate and modulate the activity of various ion channels and transporters, such as the epithelial sodium channel (ENaC) and the sodium-chloride cotransporter (NCC), which play critical roles in maintaining electrolyte balance and blood pressure regulation. Additionally, SGK participates in cell survival pathways by influencing the activity of proapoptotic and antiapoptotic proteins. Its role in cell proliferation and survival is mediated through the phosphorylation of downstream effectors like FOXO transcription factors and GSK-3β. SGK Inhibitors are typically designed as small molecules or compounds engineered to interfere with SGK's kinase activity or its interactions with upstream regulators.
