Abstract

Background: The derivatives of Phenytoin conjugated with various anilines were synthesized. The synthesized derivatives were evaluated for different physicochemical parameters along with log P values using different software programs to discover their ability to cross the blood brain barrier. The pharmacological activities such as antianxiety, skeletal muscle relaxant and anticonvulsant were evaluated by using different models.

Objective: The new Phenytoin derivatives were synthesized and evaluated for different properties to predict CNS activity. The drugs synthesized by chloroacetylation and then different aniline were added to it. The compounds were evaluated for their different CNS activity by using different methods.

Methods: The compounds were synthesized by firstly chloroacetylating the phenytoin and then different substituted anilines were added to it. The compounds were evaluated for antianxiety activity, muscle relaxant activity and anticonvulsant activity by using different models.

Results: The number of derivatives of Phenytoin was synthesized and various physicochemical parameters were optimized which revealed that the compound containing chloro groups such as C2 and C5 exhibited significant potential when compared with the standard drug Diazepam.

Conclusion: It was portrayed that the synthesis, computational studies and evaluation of anticonvulsant, antianxiety and skeletal muscle relaxant activity of new Phenytoin derivatives were carried out. The compounds were productively synthesized and portrayed by molecular docking studies. The compounds also exhibit mild to moderate similarity with respect to standard drug. The synthesized drugs have the potential to be optimized further to engender new scaffolds to treat various CNS disorders.

Keywords: Phenytoin, parameters, CNS activity, blood brain barrier, log P, CNS active.
