Introduction: Psoriasis is a refractory skin disorder,and usually requires a lifetime control.Traditional Chinese medicine(TCM)is effective and safe for this disease.However,the cellular and molecular mechanisms of TCM remedies for psoriasis are still not fully understood.TCM contains numerous natural products.Natural products have historically been invaluable as a resource of therapeutic agents.Yet,there is no integrated information about active compounds of TCM for psoriasis.Method: We use systems pharmacology methods to develop the Psoriasis Database of Traditional Chinese Medicine(PDTCM).The database covered a number of psoriasis-related information(formulas,TCM,compounds,target proteins,diseases and biomarkers).With these data information,a online platform was constucted Results: PDTCM comprises 38 empirical therapeutic formulas,34373 compounds from 1424 medicinal plants,44 psoriasis-related proteins and 76 biomarkers from 111 related diseases.On this platform,users can screen active compounds for a psoriasis-related target and explore molecular mechanisms of TCM.Accordingly,users can also download the retrieved structures and data information with a defined value set.In addition,it helps to get a better understanding of Chinese prescriptions in disease treatment.Conclusion: With the systems pharmacology-based data,PDTCM would become a valueable resource for TCM in psoriasis-related research.
