Although the rate of progress in preclinical biomedical science is high, it remains difficult to translate these findings into potential drug discovery. The major cause of attrition in the pharmaceutical industry is the lack of efficacy in phase II and III clinical trials, which may be due to insufficient target validation. Systems pharmacology is a recently introduced term that refers to the area dealing with the representation of therapeutics mechanisms of action and to improve the efficiency of innovative drug discovery and development. Previously, we reported that heme oxygenase-1 and heat shock protein 72 as potential drug targets by using rat model of cerebral vasospasm. However, there is serious problems of throughput in mammalian target validation system. In recent years in vivo chemical and genetic screening in zebrafish has emerged as a rapid and efficient method to identify drug target that modulate specific human disease processes. By performing primary screening of drug in vivo, the bioactivity, toxicity, and off-target side effects are determined from the onset of drug development. We would like to present our rencent data which suggest that zebrafish-based systems pharmacology will be powerful next generation strategy for therapeutic target validation.

UK-Japan Workshop programme

How do we identify new targets for new medicines?
