In Vitro

Tanshinone I inhibits PGE₂ formation from LPS-induced RAW macrophages (IC₅₀=38 μM). When Tanshinone I is added simultaneously with LPS, this compound clearly inhibits PGE2 production (IC₅₀=38 μM) at 10-100 μM. Tanshinone I also reduces PGE2 production (IC₅₀=46 μM) when added after COX-2 is fully induced. The fact that Tanshinone I inhibits PGE2 production by pre-induced COX-2 strongly suggests that this compound may directly inhibit COX-2 activity and/or affect PLA₂ activity. When Tanshinone I is incubated with two different forms of phospholipase A₂ (PLA₂), it clearly inhibits sPLA₂ (IC₅₀=11 μM) in a concentration-dependent manner. Although being less potent, Tanshinone I also inhibits cPLA₂ (IC₅₀=82 μM)^[1].

In Vivo

Tanshinone I shows antiinflammatory activity in rat carrageenan-induced paw oedema and adjuvant-induced arthritis. In order to establish the anti-inflammatory activity of Tanshinone I, the classical animal models of acute and chronic inflammation [rat carrageenan (CGN)-induced paw oedema and rat adjuvant-induced arthritis (AIA)] are employed. When Tanshinone I is orally administered, it shows significant anti-inflammatory activity against CGN-induced paw oedema (47% inhibition at 160 mg/kg), while the IC₅₀ of indomethacin is 7.1 mg/kg. In AIA, Tanshinone I gives 27% inhibition of secondary inflammation at 18 day with an oral dose of 50 mg/kg/day, whereas prednisolone (5 mg/kg/day) shows potent inhibition (65%)^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
