Rottlerin is a principal phenolic compound of the Kamala plant Mallotus philippinensis. It is a widely-used selective inhibitor of PKCδ (protein kinase Cδ) (IC50=3-6 μM). It also inhibits PKCα, PKCβ, PKCγ, PKCε, PKCη, PKCζ and eEF2K (CaMK III) (IC50 = 5.3 μM). In HT1080 human fibrosarcoma cells, rottlerin induces apoptosis and autophagy via a PKCδ-independent pathway. When tested on HERG (human Ether-á-go-go) channels, rottlerin increased both step and tail HERG current by leftward shifting the voltage and dependence of HERG activation and slowing channel deactivation. Rottlerin is an inhibitor of Chk2, MAPKAPK-2, Pim-3, PKCλ, PKCθ, Plk, PRAK, SRPK1 and an activator of AMPK and HERG. There have been a number of studies published with evidence against the role of Rotterlin as a specific PKCδ inhibitor.
