Graphics computer-aided receptor mapping as a predictive tool for drug design: development of potent, selective, and stereospecific ligands for the 5-HT1A receptor

Abstract: A conformational study of four 5-HT1A (serotonin) receptor ligands ((R-(-)-methiothepin, spiperone, (S)-(-)-propranolol, and buspirone) led to the definition of a pharmacophore and a three-dimensional map of the 5-HT1A antagonist recognition site. These models were used to design new compounds and successfully predict their potency, stereospecificity, and selectivity. For example, 8-[4-[(1,4-benzodioxan-2-ylmethyl)amino] butyl]-8-azaspiro[4.5]decane-7,9-dione (1, MDL 72832) has nanomolar affinity (pIC50 = 9.14… Show more

“…We focused on the core tetra cyclic structure within the ergot compounds for comparison since this portion of the ligand is believed to be involved in receptor binding [7][8][9]. An interesting structural difference be tween the rat-selective and human-selective ergots is found at the indole nitrogen.…”

“…Considerando o potencial terapêutico dos ligantes de receptores serotoninérgicos 5-HT 1A , particularmente aqueles com propriedades antagonistas, as interações de seus grupos farmacofóricos com o biorreceptor, bem como a influência do grupamento espaçador na afinidade, têm sido descritas em detalhes 48,67,68,78,96,[125][126][127][128][129][130] .…”

“…Este considera, no mínimo, a presença de um átomo de nitrogênio básico à distância de 5,2-5,8 Å a partir do centróide do anel aromático, com variação da fenila em uma faixa de 0,9 a 1,5 Å abaixo e acima do plano do anel piperazínico 132 . Estudos anteriores desenvolvidos por Hibert e colaboradores 78,133 sugerem que o desvio fora do plano entre o anel aromático e o nitrogênio básico da piperazina poderia variar em torno de 1,6 Å para antagonistas e 0,2 Å para agonistas (Figura 10). Este modelo foi referendado pelo trabalho de Agarwal e Taylor 134 que, com base nos resultados de análise comparativa de campo molecular (CoMFA), sugeriram que compostos agonistas tendem a ser mais coplanares que os antagonistas.…”

“…The 1,4-benzodioxane moiety has been widely used in the design of therapeutic agents with α-adrenergic blocking [1][2][3][4][5][6] , antigrastic 7 , spasmolytic 8 , antipsychotic 9 , anxiolytic 10 and hepatoprotective 11 properties. The biological activity of these compounds is, however, considerably influenced by the absolute configuration of the 1,4-benzodioxane unit.…”
