[ 1 ] - Novel derivatives of phthalimide with potent anticonvulsant activity in PTZ and MES seizure models

Objective(s): Phthalimide-based derivatives have anticonvulsant activity like as phenytoin by inhibition of sodium channel. In our previously research we mentioned about some phthalimide derivatives as potent anticonvulsant agents. Materials and Methods: Fourteen analogs of 2-substituted phthalimide pharmacophore were synthesized and then were evaluated for the anticonvulsant activities in pent...

[ 2 ] - Docking Studies of Phthalimide Pharmacophore as a Sodium Channel Blocker

Objective(s): Recently, phthalimide derivatives were designed based on ameltolide and thalidomide as they possess a similar degree of anticonvulsant potency due to their phenytoin-like profile. The ability of phthalimide pharmacophore to interact with neuronal voltage-dependent sodium channels was studied in the batrachotoxin affinity assay. Therefore, in the present study, a series of 19 com...

[ 4 ] - Docking, Synthesis and anticonvulsant activity of N-substituted isoindoline-1,3-dione

A series of compounds related to ameltolide were studied for anticonvulsant potential in the subcutaneous pentylenetetrazol (sc Ptz) test in mice. These compounds were synthesized and characterized by TLC followed by IR and H1NMR. In vivo screening data acquired indicate that most of analogs have the ability to protect against PTZ-induced seizure. Phenytoin (PHT) was employed as the reference p...

[ 5 ] - Design, Synthesis and Anti-Tubercular Activity of Novel 1, 4-Dihydropyrine-3, 5-Dicarboxamide Containing 4(5)-Chloro-2-Ethyl-5(4)-Imidazolyl Moiety

Current researches have showed that N3, N5-diaryl-2, 6-dimethyl -1, 4-dihydropyrine-3, 5- dicarboxamide analogues demonstrate notable anti-tubercular activity. In this study, Hantzsch condensation was used to design and synthesize new analogues of dihydropyridine (DHP). Different diary carboxamides were inserted at positions 3 and 5 of the DHP ring. 4(5)-chloro-2-ethyl-5(4)-imidazolyl moiety wa...

[ 6 ] - Application of Taguchi Method to Investigate the Effects of Process Factors on the Production of Industrial Piroxicam Polymorphs and Optimization of Dissolution Rate of Powder

Piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. In the current research, using Taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. The variables include type of solvent,...

[ 7 ] - Design, Synthesis and Evaluation of Antitubercular Activity of Novel Dihydropyridine Containing Imidazolyl Substituent

Recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. In this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using Hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at C-3 and C-5 positions of the DHP ring.In addition, 4 (5)-chloro-2-methyl-5 (...

[ 8 ] - Computational Study of Quinolone Derivatives to Improve their Therapeutic Index as Anti-malaria Agents: QSAR and QSTR

Malaria is a parasitic disease with limited chemotherapy options. Chemotherapy options are limited; moreover, drug resistant frequently occurs. The speed of drug development should be faster to overcome the emerging drug resistance. In the current study, a series of quinolone derivatives were subjected to quantitative structure activity relationship to identify the ideal physicochemical charact...
