[ 1 ] - Evaluation of Anxiolytic, Sedative-hypnotic and Amnesic Effects of Novel 2-phenoxy phenyl-1,3,4-oxadizole Derivatives Using Experimental Models
Benzodiazepines (BZDs) are widely used in clinical practice as anxiolytics, hypnotics, anticonvulsants, and muscle relaxants. However, they have some undesired effects including memory problems. In continuing our research on novel benzodiazepine ligands, we are looking for ligands with less adverse effects. Previously, 4 novel derivatives of 2-phenoxy phenyl-1,3,4-oxadiazole were synthesized as...
[ 2 ] - Design, Synthesis and Biological Evaluation of 4-Benzamidobenzoic Acid Hydrazide Derivatives as Novel Soluble Epoxide Hydrolase Inhibitors
Inhibitors of soluble epoxide hydrolase (sEH) represent one of the novel pharmaceutical approaches for treating hypertension, vascular inflammation, pain and other cardiovascular related diseases. Most of the potent sEH inhibitors reported in literature often suffer from poor solubility and bioavailability. Toward improving pharmacokinetic profile beside favorable potency, two series of 4-benza...
[ 3 ] - Optimum Conditions of Radioligand Receptor Binding Assay of Ligands of Benzodiazepine Receptors
To obtain drugs which are more selective at benzodiazepine (BZD) receptors, design and synthesis of functionally selective ligands for BZD receptors is the current strategy of our pharmaceutical chemistry department. The affinity of newly synthesized ligands is assessed by radioligand receptor binding assays. Based on our previous studies, 2-phenyl-5-oxo-7-methyl-1,3,4-oxadiazolo[a,2,3]-pyrimid...
[ 4 ] - Design, Synthesis and Anticonvulsant Activity of 2-(2-Phenoxy) phenyl-1,3,4-oxadiazole Derivatives
Benzodiazepines are useful drugs for treatment of sleep disorders, anxiety, seizure cases and skeletal muscle cramps. Some derivatives of 2-(2-Phenoxy) phenyl-1, 3, 4-oxadiazole were synthesized as benzodiazepine receptor agonists. Conformational analysis and superimposition of energy minima conformers of the compounds on estazolam, a known benzodiazepine agonist, reveal that the main proposed ...
[ 5 ] - Application of Narrow-Bore HPLC Columns in Rapid Determination of Sildenafil Citrate in Its Pharmaceutical Dosage Forms
A special type of silica-based columns has been recently introduced into the market which is called narrow-bore columns. They have lower internal volume than the standard high-performance liquid chromatography (HPLC) columns and thus reduce the solvent consumption by almost 80%. A simple, accurate and environmentally friendly reversed phase- HPLC (RP-HPLC method) which could be used in ...

[ 11 ] - Design, Synthesis, Molecular Modeling Study and Biological Evaluation of New N'-arylidene-pyrido[2,3-d]pyrimidine-5-carbohydrazide Derivatives as Anti-HIV-1 Agents
In an attempt to identify potential new agents that are active against HIV-1, a series of novel pyridopyrimidine-5-carbohydrazide derivatives featuring a substituted benzylidene fragment were designed and synthesized based on the general pharmacophore of HIV-1 integrase inhibitors. The cytotoxicity profiles of these compounds showed no significant toxicity to human cells and they exhibited anti...
