Immunopharmacology Comments
5-LOX is included in GtoImmuPdb because of its involvement in eicosanoid turnover and because it is being actively pursued as a molecular target for the development of novel anti-inflammatory therapeutics [17]. 5-LOX inhibitors with dual activity at other targets within the arachadonic acid/eicosanoid metabolic pathway (e.g. COX1/2, soluble epoxide hydrolase, mPGES1) are also being designed as more effective anti-inflammatory agents [1,3,5,7-8,11-12,16].
