Objective To establish a fast and efficient computational approach for reverse target finding of the marine small molecular compounds with antitumor biological activity. Methods This experiment mainly used the method of bioinformatics, through finding proteins related to tumor, to construct a small scale antitumor protein database, and established an accurate computational reverse target finding approach. The accuracy of this method was validated through the known experimental data. Results A computational reverse target finding method was developed based on structural molecular docking. Conclusion The known experimental results showed that this method could fast, accurately and economically predict the probable targets of the marine small molecular compounds for speeding up the search of the antitumor target.
