生物活性
Cryptotanshinone是一种STAT3抑制剂，在DU145细胞中能显着阻断STAT3 Tyr705磷酸化，但不能阻断STAT3 Ser727磷酸化，并显着抑制JAK2磷酸化，IC50为?5μM，而不影响上游激酶c的磷酸化。

溶解度
| In vitro (25°C) | DMSO | Warmed: 5 mg/mL (16.87 mM) |
| Water | Insoluble |
| Ethanol | Warmed: 1 mg/mL (3.37 mM) |
| In vivo | 5% DMSO+40%PEG 300+5% Tween80 +ddH2O | 1.18 mg/mL |
*<1 mg/ml means slightly soluble or insoluble.
*Please note that Adooq tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. |
