Ro 31-9790 is a synthetic metalloproteinase ( MMP ) inhibitor. In Vitro Ro 31-9790 inhibits L-selectin shedding from mouse and human lymphocytes, Jurkat T cells, and human monocytes with an IC 50 of 0.3-0.4 μM on these cell types. The IC 50 values obtained for Ro 31-9790 are 4.82 ± 0.75 μM, 1.16 ± 0.27 μM, 0.70 ± 0.06 μM, 4.47± 1.27 μM and 0.38 ± 0.05 μM for mouse lymphocyte L-selectin shedding, Jurkat L-selectin shedding, human lymphocyte L-selectin shedding, human monocyte L-selectin shedding and human monocyte TNF-α shedding. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:MMP
