In silico comparative molecular docking analysis and analysis of the anti-inflammatory mechanisms of action of tanshinone from Salvia miltiorrhiza

Tanshinones are a class of abietane diterpene compounds extracted from Salvia miltiorrhiza, and have been used for medical purposes in traditional Chinese medicinal practices. This herb has been used in the treatment of chronic obstructive pulmonary disease (COPD), breast cancer and inflammatory disorders. This study examined the anti-inflammatory properties of tanshinones. In addition, lipid-soluble compounds which were specific to Tanshinone class were also highlighted, out of which two compounds, dihydrotanshinone I and cryptotanshinone were selected with the aim of creating a new research perspective in order to further elucidate the mechanisms of the pathogenesis of inflammatory diseases. Moreover, interaction analyses were carried out successfully to determine the interactions formed between both dihdrotanshinone I and cryptotanshinone, and target proteins. The bioactivity properties and various other pharmacokinetic and pharmacodynamic analyses discerned that crytptotanshinone was more effective dihydrotanshinone and more ‘drug-like’ than its counterpart. It was found to have a better solubility and permeability, and thus has potential for use as an anti-inflammatory agent.
