Ophiopogonin D (OPD) is the chief pharmacological active component of the traditional Chinese herbal prescription drug-Shenmai injection (SMI), which has been used to prevent and treat cardiovascular diseases. In the present study, we investigated whether OPD protectively relieve cardiac hypertrophy against inflammation via inhibiting the expression of NF-κB and examined whether cytochrome P450 2J3 (CYP2J3)was involved in this pathway. H9c2 cells were treated with Angiotensin II (Ang II). Hypertrophy in rat was induced by administration of Ang II infusion. To evaluate the effect of OPD on disease progression and the role of CYP2J3 in this way, inflammatory mediators (NF-κB), specific hypertrophic factors and pathological change were determined in this experiment. Ang II induced hypertrophy with the elevated expression of specific hypertrophy genes and NF-κB signaling molecules. However, these inductive effects were reversed by OPD in conjunction with Ang II. Overexpression of CYP2J3 prevented the excessive expression of NF-κB. In vivo, partial pathological cardiac hypertrophy injuries were relieved after OPD treatment. OPD exerts a positive effect on alleviating cardiac hypertrophy. The mechanism is probably through inhibiting the expression of NF-κB by upregulating CYP2J3 to suppress inflammation.
