The present invention belongs to the field of natural medicine and pharmaceutical chemistry, and specifically relates to novel 2-alkyl- or 2-aromatic-substituted tanshinone I derivatives of formula (I) or a pharmaceutically acceptable salt thereof, to a process for the preparation of these compounds, compositions containing such compounds and their use in preparing antineoplastic medicaments. When Z═R, said derivative is 2-alkyl-substituted tanshinone I; when Z═Ar, said derivative is 2-aryl-substituted tanshinone I; when Z=Het, said derivative is 2-heteroaryl- or 2-heterocyclyl-substituted tanshinone I.
core of the natural product salviadione (5), a series of furan-fused BCD hybrids of 5 with 2 was rationally designed with the aim to improve both PK properties and the anti-inflammatory activity. A biomimetic synthetic approach featuring one-pot tandem N-heterocyclization was first developed for convenient assembly of salviadione (56% overall yield over 2 steps) and the designed hybrids (35–85% yields
