PKF 242-484
PKF 242-484 (TNF484) is an orally active dual inhibitor of TACE/MMPs, with Ki values of 3.6, 0.1, 0.9, 1, and 4.5 nM against hMMP-1, hMMP-2, hMMP-3, hMMP-9, and hMMP-13, respectively. PKF 242-484 inhibits the enzymatic activities of MMPs and ADAM17, reduces the release of TNF-α, suppresses the proliferation, migration and invasion of cancer cells, and regulates inflammatory cell infiltration and cytokine production. PKF 242-484 can be used in studies related to airway inflammatory diseases such as asthma and chronic obstructive pulmonary disease, intestinal ischemia-reperfusion injury, epilepsy-induced neuronal damage, and hepatocellular carcinoma.

Single administration of PKF 242-484 (10 mg/kg; p.o.) via oral gavage or intranasal instillation exerts comparable inhibitory effects on inflammatory cell infiltration and TNF-α levels[1].
PKF 242-484 (1-10 mg/kg; p.o., intranasal; administered twice daily before and after each cigarette smoke exposure; for 3 consecutive days) dose-dependently reduces bronchoalveolar neutrophilia in BALB/c mice when given via p.o., with a 46% reduction at 10 mg/kg, but shows no definite neutrophil-lowering effect in C57BL/6 mice. When administered intranasally, it dose-dependently reduces bronchoalveolar neutrophilia in BALB/c mice, with a 62% reduction at 10 mg/kg, and decreases macrophage counts at this dose; its neutrophil inhibitory effects in C57BL/6 mice are inconsistent.[4]
PKF 242-484 (1-10 mg/kg; intranasal administration; administered once 15 minutes before and 3 hours after Ovalbumins (HY-W250978) challenge) causes a significant dose-dependent reduction in ovalbumin-induced accumulation of neutrophils, eosinophils and lymphocytes in bronchoalveolar lavage fluid of C57BL/6 mice, without affecting IL-5 levels[1].
PKF 242-484 (0.1-10 mg/kg; intravenous injection; single administration 10 minutes before reperfusion) dose-dependently inhibits the production of TNF-α in serum and tissues, alleviates local and distal tissue damage, and partially reduces mortality in a mouse model of intestinal ischemia-reperfusion injury; the maximum efficacy is observed at the dose of 10 mg/kg, with 20% of treated mice surviving until 120 min after reperfusion[2].
