Abstract

The invention relates to a method for predicating novel curative effects of a medicament based on a biological process, which is disease-oriented and used to predicate a potential novel treating function of the medicament based on a medicament-disease relevance of a biological process spectrum. The method comprises the following steps of: (1) constructing a disease biological process spectrum and a medicament biological process spectrum; (2) calculating medicament-disease relevance scores on the layer of the biological process spectrum; (3) judging the significance of the relevance scores; and (4) screening a medicament-disease relation with the significance and carrying out further experimental demonstration on functions of the medicament by a user according to a sequencing result of the relevance scores. The invention further relates to an application of the method to the predication of the novel curative effects of the medicament. The predication method provided by the invention is ingenious in design, can be used for more comprehensively evaluating the medicament-disease relation, has important meanings of looking for novel medicaments for treating diseases, finding potential toxic or side effects of the medicaments, expanding a treating function space of the traditional medicaments, developing new uses for approved medicaments and the like, and is suitable for being popularized and applied on a large scale.

Description

technical field [0001] The present invention relates to the technical field of drug curative effect, in particular to the technical field of discovery of new drug curative effect, and specifically refers to a method and application for predicting new drug curative effect based on biological processes, re-evaluating the function of existing drugs, so as to discover new therapeutic functions or Potential side effects, guiding clinical medication and new drug development. Background technique [0002] New drug development is an extremely time-consuming, labor-intensive and high-risk process. From an active small molecule to its approval for marketing, an average of 800 million US dollars is required, and the cycle is 15 years. Nearly 90% of active small molecules may be eliminated in phase 1 clinical trials. Generally speaking, the main reasons for the elimination of drugs are due to poor efficacy and toxic side effects. After some drugs are approved for marketing, the market...
