Zaloglanstat (ISC-27864) is a potent inhibitor of microsomal prostaglandin E synthase-1 (mPGES-1). It is utilized in the research of various conditions, including asthma, osteoarthritis, rheumatoid arthritis, acute or chronic pain, and neurodegenerative diseases.
AF3442 is a potent and selective mPGES-1 inhibitor (microsomal prostaglandin (PG) E synthase-1). AF3442 caused a concentration-dependent inhibition of PGE(2) in human recombinant mPGES-1 with an IC(50) of 0.06microM. AF3442 is a selective mPGES-1 inhibitor which reduced monocyte PGE(2) generation also in the presence of plasma proteins. Pharmacological inhibition of mPGES-1 did not translate into redirection of PGH(2) metabolism towards other terminal PG synthases in monocytes. The functional relevance of this observation deserves to be investigated in vivo.
