Applications & references

Synthesis of the pyrazolopyridinone-based p38 mitogen-activated protein kinase inhibitor including a Suzuki coupling reaction. p38 MAP kinases are intercellular serine/threonine kinases which certainly regulate the production and action of several pro-inflammatory mediators. They are also involved in disease states such as rheumatoid arthritis, Crohn’s diseases and psoriasis.
