Structure–activity relationships in 1,4-benzodioxan-related compounds. 10. Novel α1-adrenoreceptor antagonists related to openphendioxan: Synthesis, biological evaluation, and α1d computational study
摘要:
A series of novel openphendioxan analogues were synthesized and tested at alpha(1)-adrenoreceptor (AR) subtypes by binding and functional assays. The alpha(1d)-AR binding profile was also examined by means of 2D, 3D-QSAR together with docking studies. Multiple regression analysis suggested the relevance of adequate number of heteroatoms in the whole molecule and of passive membrane diffusion to enhance alpha(1d)-AR affinity. Docking simulations against a computational structural model of the biological target further proved this evidence and furnished support for chemiometric analysis, where polar, electrostatic, hydrophobic and shape effects of the ortho substituents in the phenoxy terminal, most likely governing ligand binding, helped the depiction of pharmacophore hypothesis for the examined ligands data set.

Disclosed are novel multi-binding compounds (agents) which bind cellular receptors. The compounds of this invention comprise a plurality of ligands each of which can bind to such cellular receptors thereby modulating the biological processes/functions thereof. Each of the ligands is covalently attached to a linker or linkers which may be the same of different to provide for the multi-binding compound. The linker is selected such that the multi-binding compound so constructed demonstrates increased modulation or disruption of the biological processes/functions of the cell. Also disclosed is a method for identifying such novel multi-binding compounds which bind cellular receptors and a method for generating a mixture of such novel multi-binding compounds.
