Tenidap was a COX/5-LOX inhibitor and cytokine-modulating anti-inflammatory drug candidate[1] that was under development by Pfizer as a promising potential treatment for rheumatoid arthritis,[2] but Pfizer halted development after marketing approval was rejected by the FDA in 1996[3] due to liver and kidney toxicity, which was attributed to metabolites of the drug with a thiophene moiety that caused oxidative damage.[4]
