  Structure–activity relationships of the ultrapotent vanilloid resiniferatoxin (RTX): The side chain benzylic methylene

  摘要：

  The side chain benzylic methylene is a critical element for the vanilloid activity of resiniferatoxin (2a, RTX), and introduction of branching, oxygen functions, or isosteric substitution at this center proved detrimental, with a decrease of potency of 2-3 orders of magnitude compared to the natural product. Conversely, only a modest erosion of activity was observed upon a-methylation and alpha-methylenation of the side chain. Surprisingly, introduction of an iodine atom in the guaiacyl moiety of the oxygen isoster 2h led to an unexpected and remarkable (> 1000-fold) increase of potency, affording 2i, a compound that outperforms RTX in terms of vanilloid agonism and represents the first one-digit picomolar ligand of a TRP channel discovered to date.

  Compounds of the formula wherein A is specified nitrogen-containing heterocycle; R is H2 halogen, CH3, OCH3 or OC2H5; Ri is C1-C3 alkyl, allyl or propargyl; R2 is X1R8 or OH; X1 is 0 or S; and R8 is an organic group; and their agriculturally suitable salts, exhibit herbicidal activity, especially for the selective control of weeds in rice. The compound may be made by a variety of synthetic routes, e.g. by reacting a haloheterocycle of formula A - Hal with an alkali metal salt of the appropriate 4-hydroxy-benzene- acetate ester.
