A small molecule is a low molecular weight organic compound. Most drugs are small organic molecules. The upper molecular weight for a small molecule is approximately 900 Daltons. Small molecules, often with molecular weights of 500 or below, have proven to be extremely important to researchers to explore function at the molecular, cellular, and in vivo level. Such molecules have also been proven to be valuable for treating diseases, and most medicines marketed today are from this class. A key challenge is to identify small molecules effective at modulating a given biological process or disease state.
