One of the key elements in the early stages of drug discovery is finding good hits to develop lead compounds. Although HTS has been used as a standardized technology for hit finding, it still bears some challenging drawbacks: expensive and low-quality data. Aiming at the same goal as HTS, virtual screening (VS) has been developed to reduce cost and increase efficiency. Recent studies show that VS can deliver numerous quality hits and a few of them even reach clinical trials. This paper uses HTS as a background to discuss the contributions, limitations and research trends in VS field as these two technologies complement each other. |
