SSK1 is a compound that selectively kills senescent cells and is a precursor for β-galactosidase, which can reduce the inflammatory response of the body. SSK1 can activate the phosphorylation of p38 MAPK and MKK3/MKK6 in senescent cells, and promote mitochondrial DNA damage in senescent cells.

Desoxo-narchinol A exhibits protective effects against LPS-induced endotoxin shock and inflammation through p38 deactivation, it shows inhibitory activity against LPS-induced NO production. Desoxo-narchinol A shows cytotoxic activity against P-388 cells.

ARRY-797 (ARRY-371797) is a potent and selective p38α inhibitor and inhibits LPS-Induced IL-6.

Agrimonolide, a compound derived from isocoumarins and found mainly in the herb Agrimonia pilosa Ledeb, has significant biological activity. agrimonolide exerts anti-inflammatory effects by inhibiting lipopolysaccharide (LPS)-induced activation of JAK-STATs and p38 MAPKs signaling pathways. Agrimonolide and its derivative, desmethyl agonolide, have been shown to be effective in increasing insulin-mediated glycogen levels in hepatocytes and may play a key role in regulating insulin-resistant HepG2 cells. agrimonolide exhibits inhibitory effects on cancer progression and induction of cell death and apoptosis by targeting SCD1 in ovarian cancer cells. In particular, Agrimonolide exhibited a dose-dependent inhibition of proliferation, migration and invasion of A2780 and SKOV-3 cells, while promoting apoptosis. The compound was also found to induce iron-mediated cell death while increasing reactive oxygen species (ROS) and total iron levels.Agrimonolide readily crosses the blood-brain barrier, suggesting its potential for therapeutic applications in neurological disorders.

Scio-323 is an orally available p38 mitogen-activated protein (MAPK) kinase inhibitor.
