  • Patent number: 11779548
    Abstract: 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.

  • Patent number: 10800749
    Abstract: In alternative embodiments, the invention provides nucleophilic hydroxyimino-acetamido alkylamine antidotes that cross the blood-brain barrier (BBB) to catalyze the hydrolysis of organophosphate (OP)-inhibited human acetylcholinesterase (hAChE) in the central nerve system (CNS). The hydroxyimino-acetamido alkylamines of the invention are designed to fit within AChE active center gorge dimensions, bind with reasonable affinity, and react with the conjugated phosphate atom in the gorge. The hydroxyimino-acetamido alkylamines of the invention are also designed to possess ionization states that govern affinity and reactivity for the two linked hAChE re-activation steps.
