It is unlikely that a perfect drug candidate will emerge from these early screening runs. One of the first steps is to screen for compounds that are unlikely to be developed into drugs; for example compounds that are hits in almost every assay, classified by medicinal chemists as "pan-assay interference compounds", are removed at this stage, if ...

In 1963, its improved version, Valium, was released and became astonishingly popular: between 1969 and 1982, it was the most prescribed drug in America, with over 2.3 billion doses sold in its peak year of 1978. With Moses Wolf Goldberg, Sternbach also developed "the first commercially applicable" method for synthesizing biotin. [6]
