Biological Activity
Iberin, a sulfoxide analogue of sulforaphane, is a naturally occurring member of isothiocyanate family. It inhibits cell survival with an IC50 of 2.3 μM in HL60 cell.
In Vitro
Iberin inhibits the growth of neuroblastoma cells in a dose- and time-dependent manner. The iberin-induced cell cycle arrest in neuroblastoma cells is associated with inhibition of expression of cyclin-dependent kinase Cdk2, Cdk4, and Cdk6 proteins. There is an increase in apoptotic cell death in iberin treated cells as compared with control cells. The iberin-induced apoptosis is found to be associated with activation of caspase-9, caspase-3, and PARP[2]. Iberin inhibits growth of human glioblastoma cells in cell proliferation assays, enhances cytotoxicity, and induces apoptosis by activation of caspase-3 and caspase-9[3].
In Vivo
Iberin is tested in an in vivo foreign-body infection mouse model, and the results show no significantly difference in bacterial clearance between treated and nontreated miced[4]. Iberin increases tissue levels of the phase II detoxification enzymes quinone reductase and glutathione S-transferase in a variety of rat tissues[5].
