Abstract
The novel bioactive compound 4-(3,4-dichlorophenyl)-2-(3,4,5-trimethoxy-benzylidene)-3,4-dihydro-naphthalen-1(2 H)-one was synthesised in three different methods, namely, conventional, MW irradiation with solvent and MW irradiation without solvent. The synthesised compound was characterised by spectroscopic techniques and finally confirmed by X-ray crystal structure analysis.

Abstract
Vanol is a member of the vaulted biaryl family of ligands and it has been proven to be very effective in a number of asymmetric catalytic reactions. The previous synthesis of vanol, while effective, is limited by the cost of reagents involved. The present work evaluates three different approaches to the synthesis of 3-phenyl-1-naphthol, a key intermediate in the synthesis of vanol. The first approach has its key step as the Michael addition of a benzyl Grignard to methyl cinnamate. In the second approach the key step is the first step, a Reformatsky reaction of ethyl bromoacetate and deoxybenzoin. The final and most-efficient approach involves a dienone-phenol rearrangement of a 4-aryl-1-tetralenone generated in-situ from the reaction of 4-chloro-1-naphthol with AlCl(3) and benzene, and preliminary results are reported on the extension of this method to substituted vanol derivatives.

QSAR-CoMSIA applied to antipsychotic drugs with their dopamine D2 and serotonine 5HT2A membrane receptors. JOURNAL OF THE SERBIAN CHEMICAL SOCIETY 2011.

Abstract
Antipsychotic drugs are psychiatric medication primarily used to manage
psychosis (e.g., delusions or hallucinations), particularly in schizophrenia
and bipolar disorder. First and second generations of antipshychotics tend to
block receptors in the brain's dopamine pathways, but antipsychotic drugs
encompass a wide range of receptor targets. The inhibition constant, Ki, at
the level of membrane receptors is a major determinant of their
pharmacokinetic behavior and, consequently, it can affect their antipsychotic
activity. Here, predicted inhibition constants, Ki for 71 antipsychotics,
already approved for clinical treatment, as well as representative new
chemical structures which exhibit antipsychotic activity, were evaluated
using 3D-QSAR-CoMSIA models. Significant values of the cross-validated
correlation q2 (higher than 0.70) and the fitted correlation r2 (higher than
0.80) revealed that these models have reasonable power to predict the
biological affinity of the 15 new risperidone and 12 new olanzapine
derivatives in interactions with dopamine D2 and serotonin 5HT2A receptors;
these compounds are suggested for further studies.

Abstract
The present study is part of a long-term research project aiming to gain insight into the mechanism of action of atypical antipsychotics. Here we describe a 3D-QSAR study carried out on a series of butyrophenones with affinity for the serotonin-2A receptor, aligned by docking into the binding site of a receptor model. The series studied has two peculiarities: (i) all the compounds have a chiral center and can be represented by two enantiomeric structures, and (ii) many of the structures can bind the receptor in two alternative orientations, posing the problem of how to select a single representative structure for every compound. We have used an original solution consisting of the simultaneous use of multiple structures, representing different configurations, binding conformations, and positions. The final model showed good statistical quality (n = 426, r2 = 0.84, q2LOO = 0.81) and its interpretation provided useful information, not obtainable from the simple inspection of the ligand-receptor complexes.

Abstract
Four new diaza analogues (14, 15, 23, and 24) of the conformationally constrained aminobutyrophenone derivatives QF0104B (5) and QF0108B (6) were synthesized (Schemes 2 and 3), and evaluated for their binding affinities (Table) towards the serotonin 5-HT2A and 5-HT2C, and the dopamine D2 receptors. Among the new compounds, the quinazoline derivative 15 (= 7-{[4-(4-fluorobenzoyl)piperidin-1-yl]methyl}-5,6,7,8-tetrahydroquinazolin-5-one) exhibited the highest affinities towards the serotonin 5-HT2A and dopamine D2 receptors, and it is in the borderline of potential atypical antipsychotics. The cinnoline derivative 23 (= 7-{[4-(4-fluorobenzoyl)piperidin-1-yl]methyl}-5,6,7,8-tetrahydro-3-methylcinnolin-5-one) displayed high selectivity in its binding profile towards the 5-HT2C compared to both the 5-HT2A and D2 receptors.
