Patent number: 11779548Abstract: A high-throughput screening methods for identifying candidate anticancer medicinal agents is described herein. The candidate anticancer medicinal agents are arylfluorosulfate compounds derived from phenolic compounds. The method involves in situ generation of the arylfluorosulfate compounds in multi-well plates by reaction of phenolic compounds in DMSO with a saturated solution of SO2F2 dissolved in a solvent such as acetonitrile, in the presence of an organic base, followed by reaction of generated fluoride ion with trimethylsilanol to form volatile trimethylsilyl fluoride. Solvents, organic base, and silyl compounds are then removed, in vacuo, to afford the arylfluorosulfate compounds suitable for biological screening in cancer cell lines without further purification.Type: GrantFiled: May 11, 2020Date of Patent: October 10, 2023Assignee: THE SCRIPPS RESEARCH INSTITUTEInventors: Jie Li, Zilei Liu, Suhua Li, Peng Wu, K.
