  2-Arylureidobenzoic Acids:  Selective Noncompetitive Antagonists for the Homomeric Kainate Receptor Subtype GluR5

  摘要：

  A series of 2-arylureidobenzoic acids (AUBAs) was prepared by a short and effective synthesis, and the pharmacological activity at glutamate receptors was evaluated in vitro and in vivo. The compounds showed noncompetitive antagonistic activity at the kainate receptor subtype GluR5. The most potent compounds showed more than 50-fold selectivity for GluR5 compared to GluR6 and the AMPA receptor subtypes GluR1-4. The structure-activity relationships for the AUBAs showed distinct structural requirements for the substituents on the two aromatic ring systems. Only para-substituents were tolerated on the benzoic acid moiety (ring A), whereas ring B tolerated a variety of substituents, but with a preference for lipophilic substituents. The most potent compounds had a 4-chloro substituent on ring A and 3-chlorobenzene (6b), 2-naphthalene (8h), or 2-indole (8k) as ring B and had IC50 values of 1.3, 1.2, and 1.2,muM, respectively, in a functional GluR5 assay. Compound 6c (IC50 = 4.8 muM at GluR5) showed activity in the in vivo ATPA rigidity test, indicating that 6c has better pharmacokinetic properties than 8h, which was inactive in this test. The AUBAs are the first example of a series of noncompetitive GluR5-selective antagonists and may prove to be important pharmacological tools and leads in the search for therapeutic glutamatergic agents.

  The kinetics of the thermal Curtius rearrangement of benzoheteroaroyl azides, i.e., 2-benzofuroyl azide (2), 2-benzothenoyl azide (4), 2-indolecarbonyl azide (6), 2-, 3-, 4-, 5-, 6-, and 7-quinolinecarbonyl azides (8, 10, 12, 13, 14, and 15), and 1- and 2-naphthoyl azides (17 and 18), in toluene were studied by infrared spectrophotometry to determine how the annelation of the benzene ring to side b of 2-furoyl, 2-thenoyl, and 2-pyrrolecarbonyl azides (1, 3, and 5) and 2-, 3-, and 4-pyridinecarbonyl azides (7, 9, and 11) affects the rearrangement and its rate. The annelation effect slightly promotes the rearrangement ; the effect on the thiophene ring and pyrrole ring is greater than that on the furan ring, and the effect on the pyridine ring of 4-pyridinecarbonyl azide (11) is greater than that on the pyridine ring of 2- and 3-pyridinecarbonyl azides (7 and 9).
