Iberin (NSC 321801), a sulfoxide analogue of sulforaphane, is a naturally occurring member of isothiocyanate family. Iberin inhibits cell survival with anIC₅₀of 2.3 μM in HL60 cell. Iberin inducesapoptosis.

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].

Iberin is tested in anin vivoforeign-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].
