| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

| Shipping Condition | Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request. | ||
The roots of Salvia miltiorrhiza Bge.
| Description | 1. Isotanshinone IIA non-competitively inhibits protein tyrosine phosphatase 1B (PTP1B) activity with 50% inhibitory concentration values of 11.4±0.6 μM. (1) PTP1B acts as a negative regulator of insulin signaling, and selective inhibition of PTP1B has served as a potential drug target for the treatment of type 2 diabetes. |

PTP1B inhibitory effect of abietane diterpenes isolated from Salvia miltiorrhiza.[Pubmed:16141564]
Biol Pharm Bull. 2005 Sep;28(9):1795-7.
Protein tyrosine phosphatase 1B (PTP1B) acts as a negative regulator of insulin signaling, and selective inhibition of PTP1B has served as a potential drug target for the treatment of type 2 diabetes. In the course of screening for PTP1B inhibitory natural products, the MeOH extract of the dried root of Salvia miltiorrhiza BUNGE (Labiatae) was found to exhibit significant inhibitory effect. Bioassay-guided fractionation and purification afforded three related abietane-type diterpene metabolites 1-3. Compounds 1-3 were identified as Isotanshinone IIA (1), dihydroisotanshinone I (2), and isocryptotanshinone (3) mainly by analysis of NMR and MS data. Compounds 1-3 non-competitively inhibited PTP1B activity with 50% inhibitory concentration values of 11.4+/-0.6 microM, 22.4+/-0.6 microM and 56.1+/-6.3 microM, respectively.
Isotanshinone IIA, an abietane-type diterpene metabolite, could non-competitively inhibit Protein Tyrosine Phosphatase 1B (PTP1B) activity with an IC50 0f 11.4 μM.
