MrgB13 Inhibitors

The chemical class of MrgB13 inhibitors comprises a diverse group of compounds that can interfere with the signaling and trafficking of the MAS-related GPR, member B13 receptor. Inhibitors in this class operate through various mechanisms affecting receptor function. Some function by impeding the internalization or recycling of the receptor, such as Substance P, which can lead to receptor desensitization, Chloroquine, which affects intracellular vesicle pH and receptor recycling, and Dynasore, which disrupts dynamin-mediated endocytosis. Other compounds like ML-141 and SecinH3 interfere with GTPases that regulate cytoskeletal dynamics and membrane trafficking, which are crucial for receptor signaling. Brefeldin A and Monensin can disrupt cellular organelles and ion gradients, respectively, which are vital for proper receptor localization and function.

Additional inhibitors affect the cytoskeleton directly, such as Cytochalasin D and Latrunculin A, which inhibit actin polymerization, and Nocodazole, which disrupts microtubules, all leading to potential alterations in MrgB13 receptor distribution and downstream signaling. Lastly, compounds like Gö6976 and Wiskostatin modulate signaling pathways, with Gö6976 targeting protein kinase C, thereby influencing MrgB13 indirectly, and Wiskostatin affecting the N-WASP-Arp2/3 complex involved in actin remodeling, which can impact receptor trafficking. These inhibitors can alter the signaling of MrgB13 by modifying the cellular environment and machinery that control receptor activity and expression.
