Tryptamine and homotryptamine-based sulfonamides as potent and selective inhibitors of 15-lipoxygenase
摘要:
A series of inhibitors of mammalian 15-lipoxygenase based on tryptamine and homotryptamine scaffolds is described. Compounds with aryl substituents at C-2 of the indole core of tryptamine and homotryptamine sulfonamides (e.g., 37a-p) proved to be potent inhibitors of the isolated enzyme. Selected compounds also demonstrated desirable inhibition selectivities over isozymes 5- and P-12-LO. (c) 2005 Elsevier Ltd. All rights reserved.

The free amine-directed C–H functionalization reactions are challenging and mainly restricted to bulky amines. In this work, we report the nonsteric NH2-directed Pd(II)-catalyzed intramolecular C(sp2)–H arylation of tryptamines, which enables the efficient, gram-scale, and regioselective synthesis of versatile 2-aryltryptamines (35 examples, up to 98% yield). This approach broadens the substrate scope
