Cercosporamide (CAS 131436-22-1)

Cercosporamide is a small molecule compound derived from fungi, specifically identified as a secondary metabolite produced by Cercospora species. It is predominantly known for its role as a potent and specific inhibitor of mitogen-activated protein kinase (MAPK) pathways, particularly focusing on the Pkc1 signaling pathway in fungi. This pathway is crucial for various cellular processes including growth, differentiation, and response to external stresses. Scientific research on cercosporamide has primarily explored its potential as a tool for dissecting biochemical pathways in fungal organisms. By inhibiting the MAPK pathway, cercosporamide can disrupt cell wall synthesis and integrity, leading to cell death in susceptible fungi. This action is particularly valuable in studies aiming to understand fungal pathogenicity and resistance mechanisms against environmental stresses. Moreover, cercosporamide has been utilized in biochemical assays to study its inhibitory effects on various kinases, contributing significantly to the understanding of kinase-related signaling pathways. The compound′s ability to selectively inhibit specific kinases while sparing others makes it a useful probe in cellular biology to explain the roles of these enzymes in complex biological systems.
