GEA 3162 is an orally active compound that acts as a NO/ONOO⁻ donor. GEA 3162 significantly inhibits the activation of human polymorphonuclear leukocytes (PMNs) through the cGMP pathway, inhibits the release of inflammatory mediators, and exerts anti-inflammatory and protective effects. GEA 3162 induces apoptosis of neutrophils and bone marrow cells by activating caspase-2/3/8/9 through the ONOO⁻ pathway. GEA 3162 has a bidirectional effect in the rat gastric ulcer model: at low doses, it significantly reduces gastric mucosal damage, while at high doses, it aggravates the ulcer area. GEA 3162 can be used for research on inflammatory conditions such as gastric ulcers .

Leukotriene B5 (LTB5) is a leukotriene with diverse biological activities. It is a metabolite of eicosapentaenoic acid formed through the 5-lipoxygenase (5-LO) pathway. LTB5 increases contraction of bullfrog lung strips ex vivo in a concentration-dependent manner. In vivo, LTB5 (100 nM) reduces tumor volume in mice injected with Tm1 murine melanoma cells. LTB5 also elicits chemokinesis and lysosomal enzyme release from polymorphonuclear leukocytes (PMNLs) 20- to 30-fold less, and induces platelet aggregation 8-fold less, potently than LTB4.
