Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases peak currents at all voltages and stimulates a persistent Na+ current at hNav1.7 channel. Increases hyperpolarization at Nav1.4 and Nav1.6 channels. Induces spontaneous pain in vivo.

Mycophenolate Mofetil(RS 61443) is a non-competitive, selective and reversible inhibitor of inosine monophosphate dehydrogenase I/II with IC50 of 39 nM and 27 nM, respectively.

Rubioncolin C shows good cytotoxicity with IC50 value of 1.53 μM and NF-κB inhibitory activity with IC50 value of 2.97 μM.
