Kobusin, a Calmodulin inhibitor, shows mild antiplasmodial,anti-inflammatory, and cytotoxic activities; it may be beneficial for the treatment of neuro-inflammatory diseases through the inhibition of iNOS expression and peroxynitrite scavenging potential. Kobusin can mildly reduce gastrointestinal motility in mice, it activates CFTR and CaCCgie chloride channel activities in mouse colonic epithelia and shows inhibitory effects toward ANO1/CaCC-mediated short-circuit currents in ANO1/CaCC-expressing FRT cells.

In this study, we identified major volatile constituents present in different solvent fractions of Z. rhetsa bark using GC-MS analysis and isolated two tetrahydrofuran lignans (yangambin and Kobusin), a berberine alkaloid (columbamine) and a triterpenoid (lupeol) from the bioactive chloroform fraction. The solvent fractions and purified compounds were tested for their cytotoxic potential against human dermal fibroblasts (HDF) and mouse melanoma (B16-F10) cells, using the MTT assay. All the solvent fractions and purified compounds were found to be non-cytotoxic to HDF cells. However, the chloroform fraction and Kobusin exhibited cytotoxic effect against B16-F10 melanoma cells[1]
