A systems pharmacology approach to identify the autophagy-inducing effects of Traditional Persian medicinal plants.

Aging is correlated with several complex diseases, including type 2 diabetes, neurodegeneration diseases, and cancer. Identifying the nature of this correlation and treatment of age-related diseases has been a major subject of both modern and traditional medicine. Traditional Persian Medicine (TPM) embodies many prescriptions for the treatment of ARDs. Given that autophagy plays a critical role in antiaging processes, the present study aimed to examine whether the documented effect of plants used in TPM might be relevant to the induction of autophagy? To this end, the TPM-based medicinal herbs used in the treatment of the ARDs were identified from modern and traditional references. The known phytochemicals of these plants were then examined against literature for evidence of having autophagy inducing effects. As a result, several plants were identified to have multiple active ingredients, which indeed regulate the autophagy or its upstream pathways. In addition, gene set enrichment analysis of the identified targets confirmed the collective contribution of the identified targets in autophagy regulating processes. Also, the protein-protein interaction (PPI) network of the targets was reconstructed. Network centrality analysis of the PPI network identified mTOR as the key network hub. Given the well-documented role of mTOR in inhibiting autophagy, our results hence support the hypothesis that the antiaging mechanism of TPM-based medicines might involve autophagy induction. Chemoinformatics study of the phytochemicals using docking and molecular dynamics simulation identified, among other compounds, the cyclo-trijuglone of Juglans regia L. as a potential ATP-competitive inhibitor of mTOR. Our results hence, provide a basis for the study of TPM-based prescriptions using modern tools in the quest for developing synergistic therapies for ARDs.

A panoramic view of chronic liver diseases and natural remedies reported in Traditional Persian Medicine.

Regarding limited effectiveness of many hepatic medical approaches, seeking for novel treatment strategies is crucial to improve outcomes. Hence, the current study aims to compile a concise but critical review over reported liver diseases and related medicinal plants from the Persian medicine perspectives. To this end, five main pharmaceutical manuscripts of Persian medicine from 9th-18th A.D. as well as the latest and largest medical textbook of Persian medicine were studied. By searching through databases such as PubMed and ScienceDirect, mechanisms or pharmacological activities of reported medicinal plants in the field of liver diseases were cited and discussed. In all, seventeen different liver diseases, mainly chronic, were cited in Persian medicine. Ninety three medicinal plants with liver tonic, hepatoprotective and related effectiveness belonging to 49 families were derived and authenticated from these studied manuscripts. More than 75% of the herbs showed related hepatoprotectivity and antioxidant activities. However, none of them have been examined clinically. Besides historical clarification, the current investigation compiled an evidence- based study on reported liver herbal remedies from the standpoints of Persian scholars. Conducting attributable clinical trials against the backdrops of proven in vitro and in vivo studies may result in new treatment discoveries for liver diseases.
