The invention discloses a network pharmacology method used for finding active ingredients of traditional Chinese medicine and effect targets thereof. The network pharmacology method comprises the steps as follows: chemical compounds and proteins that can build training sets are collected, and characteristic descriptors are calculated according to molecular structures of the chemical compounds and amino acid sequences of the proteins; the training sets are built based on the characteristic descriptors of the chemical compounds and the proteins, predictive models relative to the interaction of the chemical compounds and the proteins are built according to a machine learning method; the known chemical compound ingredients of the traditional Chinese medicine needing to be forecasted, the characteristic descriptors are calculated, and forecast sets are built; the built predictive models are utilized to forecast the forecast sets, and the chemical compounds and the proteins with the forecasted interaction results greater than a given threshold are used for building a network; and the chemical compounds and the proteins with larger network node connection number are the potential active ingredients and the potential effect targets. The network pharmacology method can improve the finding accuracy rate and finding efficiency of the active ingredients of the traditional Chinese medicine and the effect targets.

The invention provides a method of exploring a new indication of a drug. The method comprises the steps of searching, based on a drug name, drug-related molecules (genes or proteins) in a database; building an interaction network of the drug-related molecules (genes or proteins) or the drug-related molecules (genes or proteins) and first-order neighbors thereof; performing module identification on the interaction network, building a weighted or unweighted module interaction network, and performing key module identification so as to analyze functions, or directly performing function analysis of the drug-related molecules (genes or proteins) on the interaction network; and comparing a function analysis result with a known indication in a specification of the drug so as to obtain the new indication of the drug. The method uses a network pharmacology method and starts with characteristics of multiple targets and multiple paths of the drug go explore the new indication of the drug in multiple aspects such as drug-related molecules, modules and network. Compared with research of a brand-new drug, the method saves much manpower, financial and time costs, lowers the research risks, and uses existing drug resources more reasonably.
