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.

An Artificial Oxygenase Built from Scratch: Substrate Binding Site Identified Using a Docking Approach
The substrate for an artificial iron monooxygenase was selected by usingdocking calculations. The high catalytic efficiency of the reported enzyme for sulfide oxidation was directly correlated to the predicted substratebinding mode in the protein cavity, thus illustrating the synergetic effect of the substratebindingsite, protein scaffold, and catalytic site.
