The Scottish Government believes in the new strategy of phenotypic screening rather than target screening since they invest £8 million for university of Dundee and as they said: “Phenotypic screening is thought to be a powerful method for drug discovery because it offers the opportunity to go beyond the focus on single drug targets, 
which has traditionally been the most widely adopted approach for drug discovery.

Current systems have been plagued by low success rates in early development, as well as expensive late-stage failure of many new drugs in second or third phase trials, insiders said.”
