Sulfonyl Fluoride Inhibitors of Fatty Acid Amide Hydrolase
摘要:
Sulfonyl fluorides are known to inhibit esterases. Early work, from our laboratory has identified hexadecyl sulfonylfluoride (AM374) as a potent in vitro and in vivo inhibitor of fatty acid amide hydrolase (FAAH). We now report on later generation sulfonyl fluoride analogs that exhibit potent and selective inhibition of FAAH. Using recombinant rat and human FAAH, we show that 5-(4-hydroxyphenyl)pentanesulfonyl fluoride (AM3506) has similar inhibitory activity for both the rat and the human enzyme, while dilution assays and mass spectrometry analysis suggest that the compound is a covalent modifier for FAAH and inhibits its action in an irreversible manner. Our SAR results are highlighted by molecular docking of key analogs.
and 3° alkyl iodides to ethenesulfonyl fluoride, employing Hantzschester as a hydrogen source at room temperature was developed. This method featured a wide substrate scope and great functional group compatibility, providing facile and robust process to alkyl sulfonyl fluorides including enzyme inhibitors, natural products and drugs derivatives in up to 99% yield. Further derivatization of resultant
Radical hydro-fluorosulfonylation of olefins has been successfully achieved by employing FABI as a FSO2-radical precursor and ODA as an organic photocatalyst. With this photocatalytic system, radical hydro-fluorosulfonylation of alkynes can also be realized with a unique, high Z-selectivity. Utilization of this method is further demonstrated in the late-stage modification of natural products and drug
emerging as key structural motifs in organic synthesis, medicinal chemistry, and materials science. Herein we report two efficient and complementary methods for direct decarboxylative fluorosulfonylation of carboxylic acids by the merging of copper catalysis with different N-centered HAT regents. A widerange of structurally diverse sulfonyl fluorides was readily accessed from primary, secondary, and tertiary
磺酰氟正在成为有机合成、药物化学和材料科学中的关键结构基序。在这里,我们报告了两种有效且互补的方法,通过将铜催化与不同的以N为中心的 HAT 试剂相结合,对羧酸进行直接脱羧氟磺酰化。在温和条件下,一步即可从伯、仲和叔羧酸中轻松获得多种结构多样的磺酰氟。
