The reactivity of Isothiocyanatoazobenzene 2 towards some nucleophiles was investigated. Thus, reaction of isothiocyanate 2 with aromatic amines gave thioureas 3a–d . The reaction of compound 3a with arylidenemalononitriles 4a,b afforded the corresponding 1,3-pyrimidines 7a , b . Thiosemicarbazide 8 and ethyl thiocarbamate 9 were synthesized by interaction of isothiocyanate 2 with hydrazine hydrate
The phenyl (thio) semicarbazide derivatives of phthalimido pharmacophore were synthesized and evaluated for their anticonvulsant and neurotoxic properties. Initial anticonvulsant screening was performed using intraperitoneal (i.p.), maximal electroshock-induced seizure (MES), subcutaneous pentylenetetrazole (scPTZ) and subcutaneous strychnine (sc STY)-induced seizure threshold tests in mice.
