SERP+ Comments:

Only one off-target, MAPK14, has been determined. Structure alert: the compound is a potential metal chelator for e.g., Zn, Cu, Mn, and Fe ions. It has insufficient solubility for animal studies. There are some discrepancies between Figure 9 and Table 5 for cell lysates.

SERP+ Comments:

In terms of selectivity SRPK1, SRPK2 and SRPK3 should be regarded as isoforms, and hence, the inhibitor is expected to be active on all three. Selectivity within family (kinases) has been evaluated well in biochemical assay demonstrating no off-target activity.
