Chemistry:Pan-assay interference compounds

From HandWiki

File:PAINS Figure.tif Pan-assay interference compounds (PAINS) are chemical compounds that often give false positive results in high-throughput screens.[1] PAINS tend to react nonspecifically with numerous biological targets rather than specifically affecting one desired target.[2] A number of disruptive functional groups are shared by many PAINS.[2][3][4]

While a number of filters have been proposed and are used in virtual screening and computer-aided drug design,[5] the accuracy of filters with regard to compounds they flag and don't flag has been criticized.[6]

Common PAINS include toxoflavin, isothiazolones, hydroxyphenyl hydrazones, curcumin, phenol-sulfonamides, rhodanines, enones, quinones, and catechols.[7]
