Bioactivity | Phenylbutazone is an efficient reducing cofactor for the peroxidase activity of prostaglandin H synthase (PHS). Phenylbutazone, a hepatotoxin, is a nonsteroidal anti-inflammatory drug (NSAID). Phenylbutazone induces muscle blind-like protein 1 (MBNL1) expression and has the potential for ankylosing spondylitis research[1][2]. | ||||||||||||
Invitro | Phenylbutazone has low inhibition of COX-1 and COX-2[3]. | ||||||||||||
