A Monte Carlo pharmacophore generation procedure: Application to the human PAF receptor

Abstract: A novel pharmacophore definition procedure is described, which uses a Monte Carlo method to superimpose molecules. Pharmacophore space is searched by a technique similar to high temperature annealing. Subsequent refinement of candidate pharmacophores by energy minimization produces low-energy conformations that may be involved in receptor binding. The method has been applied to compounds that bind to the human platelet-activating factor (PAF) receptor. Alternative binding site models for the PAF receptor are p… Show more

“…The construction of pharmacophore models (a pharmacophore is a spatial arrangement of atoms that may give rise to a biological activity) is a key process in computer assisted drug design (28)(29)(30). In pharmacophore mapping techniques (2,(31)(32)(33) the assumptions are often made that (i) there exists a commonality between isolated structures of ligands (2) and (ii) their low energy solution structures are similar to the conformations they adopt in the receptor binding site. The importance of this similarity extends beyond the scope of computer assisted drug design to questions related to the physics of binding.…”

“…Tentativas foram feitas para modelar o PAFr 74,75 , mas os modelos resultantes ainda são muito imprecisos para explicar as sutis exigências estruturais que resultam em elevada afinidade de seus agonistas e antagonistas 76 . Um modelo mais específico de receptor 76 77 para antagonistas de 17 (Fig.…”

“…Over the years, a variety of techniques have been developed for this purpose including the active analogue approach [47][48][49][50] and ensemble distance geometry [51]. More recently, methods based on clique detection [46,52] and genetic algorithms [54] have emerged together with other novel techniques [53,55,56].…”
