As a natural quinone compound, the medicinal value of cryptotanshinone (CT) has received increasing attentions, but there is no systematic literature review that describes the pharmacological activity of CT. This paper reviewed the pharmacology research of CT, with a primary focus on its anti-tumor activity. We also discussed the underlying molecular mechanisms, and proposed future outlooks. In addition to anti-tumor activity, CT was found to have anti-inflammatory, neuroprotective, cardioprotective, visceral protective, anti-metabolic disorders and other abilities. Furthermore, the potential molecular mechanisms contributing to the anti-tumor effect of CT likely involve the following aspects: the induction of apoptosis, targeting of ER and AR, reversion of MDR, combined pharmacotherapy, and the inhibition of cell proliferation, migration, and invasion. We also found that different pharmacological effects involved various signaling pathways. Among them, STAT3-related signaling pathways played a vital role in the CT-mediated induction of tumor cell apoptosis and proliferation, while NF-κB signal pathway also was essential for inhibition of inflammation by CT. Furthermore, CT could significantly enhance the activities of several anticancer drugs and reverse their resistances in tumors. Therefore, we proposed suggestions for future studies of CT, including enhancing anti-tumor activity by targeting STAT3-related receptors, targeting NF-κB-related pathways to inhibit inflammatory responses, enhancing anti-tumor efficacy by combining with anti-tumor drugs, and further studying the dose-effect relationship to ensure safer and more effective applications of CT.
