Synthesis, characterization and interaction mechanism of new oxadiazolo-phthalimides as peripheral analgesics. IV
摘要:
The synthesis, characterization and spectroscopic studies of compounds 6a-g with analgesic activity is described. A new model of interaction between the drug and the enzyme is suggested. Application of the Resonance Valence Bond theory led us to propose. for the first time, an entirely new mechanism involving an electron transfer from the amino acid residue of the enzyme to the drug. Theoretical studies of various transition states involved in the interaction mechanism employing the semi-empirical molecular orbital calculations (AMI method) have been carried out. This article also deals with an extensive study of the structure-activity relationships of seven oxadiazolo-phthalimides 6a-g. (C) 2003 Elsevier B.V. All rights reserved.

Seven new phthalimide derivatives (9a-g) with 1,2,4-oxadiazol-5-yl methyl group attached to nitrogen have been synthesized from N-phthaloylglycine 6 and arylamidoximes 7a-g. All of these showed potentanalgesic effect with acetic acid induced "writhing" test in mice. One of the better compounds (ID50 = 2.2 mg/Kg i.p.) has been found to be 9a which also demonstrates analgesic activity against inflammatory
由N-邻苯二甲酰基甘氨酸6和芳酰胺基肟7a-g合成了七个新的具有与氮相连的1,2,4-恶二唑-5-基甲基的邻苯二甲酰亚胺衍生物(9a-g)。所有这些都显示了乙酸引起的小鼠“扭体”试验的有效镇痛作用。发现更好的化合物之一(ID50 = 2.2 mg / Kg ip)为9a,它也显示出抗炎性疼痛的镇痛活性。
