XL-784 free base is a selectivematrix metalloproteinases(MMP)inhibitor, withIC₅₀sof ~1900, 0.81, 120, 10.8, 18, 0.56 nM forMMP-1,MMP-2,MMP-3,MMP-8,MMP-9andMMP-13, respectively^[1][2].

XL-784 is a highly potent, low-molecular-weight (1,122 g/mol) inhibitor of MMPs that has very limited aqueous solubility (20 μg/mL). XL-784 potently inhibits MMP-2, MMP-13, and ADAM10 [TNF-α-converting enzyme (TACE)] activity in vitro, with IC₅₀values in the range of 1-2 nM. XL-784 also inhibits MMP-9 (IC₅₀~20 nM) activity and ADAM17 (IC₅₀~70 nM) also known as TACE. However, it exhibits low potency for inhibition of MMP-1 (IC₅₀~2,000 nM)^[1].

All mice tolerate the treatments similarly. Control mice all developed aneurysms with a mean %△AD of 158.5%±4.3%. Treatment with all doses of XL-784 and doxycycline are effective in inhibiting aortic dilatation. There is a clear dose-response relationship between XL-784 and reductions in aortic dilatation at harvest (50 mg/kg 140.4% ±3.2%; 125 mg/kg 129.3% ±5.1%; 250 mg/kg 119.2%±3.5%; allPs<0.01 compared to control). This continues with the higher doses (375 mg/kg 88.6%±4.4%; 500 mg/kg 76.0%±3.5%). The highest 2 doses of XL-784 tested are more effective than doxycycline (112.2%±2.0%, P<0.05) in inhibiting maximal dilatation of the aorta after elastase perfusion^[2].
