SYNTHESIS AND STRUCTURE-ACTIVITY RELATIONSHIP OF 1-ALLYL-3-(2-CHLOROBENZOYL) THIOUREA AS ANALGESIC
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2016, Vol 8, Issue 6
Abstract
Objective: The research was aimed to synthesize 1-allyl-3-(2-chlorobenzoyl) thiourea and determine its analgesic activity in mice (Mus musculus).Methods: The synthesis was carried out by modified Schotten-Baumann reaction, via nucleophilic substitution reaction of allylthiourea on 2-chlorobenzoyl chloride. The analgesic test was done by writhing test on mice (Mus musculus).Results: Pure 1-allyl-3-(2-chlorobenzoyl) thiourea was obtained, confirmed by means of UV, IR, 1H-NMR, 13C-NMR, and MS spectroscopy. The compound showed better pain inhibition activity compared to diclofenac sodium, with ED50 = 15.440 mg/kg BW.Conclusion: The compound 1-allyl-3-(2-chlorobenzoyl) thiourea can be synthesized by one-step modified Schotten-Baumann reaction, and showed a good analgesic activity. The compound needs further investigation as a potential analgesic drug candidate.Keywords: 1-allyl-3-(2-chlorobenzoyl)thiourea, Modified Schotten-Baumann, Analgesic activityÂ
