16-Hydroxycleroda-3,13-dien-15,16-olide (16ξ-Hydroxycleroda-3,13-dien-15,16-olide; HCD), a clerodane diterpene, is a potent serine protease dipeptidyl peptidase 4 (DPP-4) inhibitor. 16-Hydroxycleroda-3,13-dien-15,16-olide down-regulates LPS-induced ERK phosphorylation in myocyte but blocks GLP-1 induced PKA expression. 16-Hydroxycleroda-3,13-dien-15,16-olide exhibits hypolipidemic, hepatoprotective, hypoglycemic efficacy[1].
