Antiandrogenic, Maspin Induction, and Antiprostate Cancer Activities of Tanshinone IIA and Its Novel Derivatives with Modification in Ring A
摘要:
Expression of metastatic suppressor maspin is lost in advanced prostate cancer. Clinically relevant mutations in androgen receptor (AR) convert antiandrogens into AR agonists, promoting prostate tumor growth. We discovered tanshinone IIA (TS-IIA) is a potent antagonist of mutated ARs and induces maspin expression through AR. TS-IIA suppressed AR expression and induced apoptosis in LNCaP cells. Syntheses of TS-IIA derivatives (1-9) revealed that the 4,4-dimethyl group at ring A is important for TS-IIA's antiandrogenic and maspin induction activities.

A method for disaggregating amyloid peptide aggregates the method comprising administering a tanshinone or a tanshinone derivatives to an amyloid peptide aggregate. The method may be useful for disaggregating amyloid peptide aggregates in a patient in need of such treatment, such as patients with Alzheimer's disease.
