Synthesis and Anticonvulsant Activity Evaluation of Some 1-alkoxy-4-(1H-1,2,4-triazol-1-yl)phthalazines

A series of 1-alkoxy-4-(1H-1,2,4-triazol-1-yl)phthalazine derivatives were synthesized using 2,3-dihydrophthalazine-1,4-dione as starting material. The structures of the compounds were characterized by elemental analysis, IR, H-1-NMR and MS data. Anticonvulsant activities of these compounds were evaluated by maximal electroshock (MES) test following intraperitoneal injection in mice. Among the synthesized compounds 3a-3t, compound 3e was the most active compound with an ED50 of 28.9 mg/kg, TD50 of 173.6 mg/kg and protective index (PI) of 6.0.

Quinazoline and phthalazine derivatives as novel melatonin receptor ligands analogues of agomelatine

For further development of successors of Agomelatine through modulation of its pharmacokinetic properties, we report herein the design, synthesis and pharmacological results of a new family of melatonin receptor ligands. Issued from the introduction of quinazoline and phthalazine scaffolds carrying an ethyl amide lateral chain and a methoxy group as bioisosteric ligands analogues of previously developed Agomelatine. The biological activity of the prepared analogues was compared with that of Agomelatine. Quinazoline and phthalazine rings proved to be a versatile scaffold for easy feasible MT1 and MT2 ligands. Potent agonists with sub-micromolar binding affinity were obtained. However, the presence of two nitrogen atoms resulted in compounds with lower affinity for both MT1 and MT2, in comparison with the parent compound, balanced by the exhibition of good pharmacokinetic properties.

Enantioselective Fluorocyclizations Mediated by Amino-Acid-Derived Phthalazine

Novel amino-acid-derived phthalazine reagents have been designed and synthesized for the enantioselective fluorocyclizations of prochiral indoles. The scope of reaction is evidenced by 28 examples of fluorinated furoindole and pyrroloindole heterocycles bearing various functionalities with up to 99% ee. The resulting enantioenriched fluorinated products are found to be potent AChE inhibitors. Advantages of the current new chiral reagents include ease in the synthesis of analogues and readily tunable steric/electronic demands.

Tropical and Subtropical Parasitic Diseases: Targets for a New Approach to Virtual Screening

Computational techniques are widely used to reduce costs associated with new drug development with the ability to bind a specific molecular target. These studies need a Brookhaven protein data bank structure sample of the enzyme interaction with an inhibitor of adequate size. In this context, a new computational methodology is postulated to be used when there are no published samples fulfilling this requirements. In this study, 7 compounds, which showed anti-T. cruzi, L. donovani and L. infantum properties, and proved to be inhibitors of their Fe-SOD enzymes, have been theoretically evaluated against related parasites Fe-SOD enzymes, which have been proposed as targets for antiparasitic drugs. This methodology may be applied to similar cases and also to generate starting structures to be used with different CADD methods

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 89-86-1, in my other articles.

Deep eutectic solvent an efficient reaction medium for the synthesis of chromeno pyrazolo and indazolo phthalazine derivatives

The volatile, harmful and hazardous solvents have impact on human health, all organisms and environment. To reduce the use of hazardous volatile solvents, there is need to develop the alternative green reaction medium for organic transformations and is the main goal of green chemistry. The green solvent should be nonvolatile, nontoxic, biodegradable and biorenewable. Considering these parameters, herein, we have reported an efficient and environmentally benign green synthesis of chromeno pyrazolo and indazolo phthalazine derivatives in deep eutectic solvent.
