Cryptotanshinone is a quinoid diterpene isolated from the root of the Asian medicinal plant, Salvia miotiorrhiza bunge. Recently it was discovered that the compound is a potent STAT3 inhibitor. Cryptotanshinone rapidly inhibited STAT3 Tyr705 phosphorylation through a JAK2-independent mechanism. Cryptotanshinone selectively inhibits STAT3-activated cell lines through binding to monomer STAT3, subsequently blocking the dimerization and inhibiting STAT3 transcriptional regulatory activity. Previously, it was reported that the compound counteracts inflammation through the inhibition of cyclooxygenase II activity and endothelin-1 expression. In traditional oriental medicine dried roots of Salvia Miltiorrhiza Bunge (Danshen) have commonly been used for the treatment of circulatory disorders, liver disease, coronary heart disease, hepatitis, and chronic renal failure.

Dampening tumor growth by converting tumor-associated macrophages (TAMs) from M2/repair-types to M1/kill-types is of high interest. Here, we show that cryptotanshinone (CPT) can function as an antitumor immune modulator that switches TAMs from an M2 to an M1 phenotype, leading

Coronary microembolization (CME) is a prevalent cardiovascular disease, especially nowadays when percutaneous coronary intervention is widely applied. However, neither cardio-protective agents nor devices for distal protection could effectively prevent the occurrence of CME. Therefore, we aimed to develop a new
