P38 α MAPK is the main subtype of the p38 MAPK family, encoded by the MAPK14 gene. When cells are exposed to stimuli such as ultraviolet radiation, cytokines, oxidative stress, etc., p38 α MAPK is activated through a three-level kinase cascade reaction (MAPKKK → MAPKK → MAPK). Activated p38 α MAPK can phosphorylate downstream transcription factors such as AP-1 and ATF-2, regulate the expression of inflammatory factors (TNF - α, IL-6, etc.) and cell cycle related proteins, and participate in physiological processes such as inflammation, cell proliferation, differentiation, and apoptosis.

P38 α MAPK inhibitors mainly exert anti-inflammatory and anti-tumor effects by inhibiting the activity of p38 α MAPK and blocking its signaling pathway. According to their different mechanisms of action, p38 α MAPK inhibitors can be divided into ATP competitive inhibitors and allosteric inhibitors. ATP competitive inhibitors occupy the ATP binding pocket of p38 α MAPK, preventing ATP from binding to p38 α MAPK and thus inhibiting its phosphorylation activity;

Identifying the active fragments in this substance is a key step in developing novel p38 α MAPK inhibitors. Common methods for identifying active fragments include structure based drug design (SBDD), fragment based drug design (FBDD), and virtual screening. The SBDD method analyzes the three-dimensional structure of p38 α MAPK to determine its active sites and key interaction sites, and then designs compound fragments that can bind to p38 α MAPK based on this information.

To verify whether the identified active fragments have inhibitory activity against p38 α MAPK, a series of experiments are needed for validation. Common experimental methods include kinase activity assay, cell experiments, and animal experiments. The kinase activity assay is a direct method to verify the inhibition of p38 α MAPK activity by active fragments. By measuring the inhibitory effect of active fragments on p38 α MAPK catalyzed substrate phosphorylation, the half maximal inhibitory concentration (IC ₅₀) is calculated to evaluate their inhibitory activity.

Taking SB203580 as an example, it is a classic p38 α MAPK ATP competitive inhibitor with a pyridine imidazole aryl heterocyclic structure in its molecular structure. Research has shown that the pyridine ring plays an important role in the binding of SB203580 to p38 α MAPK, and can form hydrogen bonds and hydrophobic interactions with specific amino acid residues in the ATP binding pocket of p38 α MAPK, thereby stabilizing the binding.
