Just shared a PAINS Map & Filter component on the Protocol Exchange on ScienceCloud.

Wikipedia: Pan-assay interference compounds (PAINS) are chemical compounds that often give false positive results in high-throughput screens. 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.

Thanks @MH for the original protocol, and @MS for the advice :)
