In Vitro	TGFβRI-IN-2 (compound 18) at 1 μM shows a 31% inhibition of MAP3K2 (MEKK2) with an IC50 value of 2.2 μM[1].
In Vivo	TGFβRI-IN-2 (oral administation; 50, 150 and 500 mg/kg; 5 days) induces cardiovascular toxicity characterized by valvular interstitial cell proliferation, neutrophil presence, hemorrhage and fibrin deposition in the heart valves[1]. Animal Model: Rats[1] Dosage: 50, 150 and 500 mg/kg Administration: Oral administation; 50, 150 and 500 mg/kg; 5 days Result: Induced cardiovalvulopathy in both the medium and high dose animal groups.
