The current work describes the synthesis of new series of N-(1-(cyclohexylcarbamoyl) cyclohexyl)-N-phenylarylamides (10 a-h) and 3-cyclohexyl-1,2-diphenyl and 2-(substituted phenyl)-1,3diazaspiro[4.5]decanes (12 a-h).The new compounds were screened for their anticonvulsant and antinociceptive activities using sodium valproate and tramadol hydrochloride, respectively as reference standards. 4-Chloro-N-(1-(cyclohexylcarbamoyl)cyclohexyl)-N-phenylbenzamide (10 b), 3-Cyclohexyl-1,2diphenyl-1,3-diazaspiro[4.5]decane (12 a) and 3-Cyclohexyl-1phenyl-2-(3,4,5-trimethoxyphenyl)-1,3-diazaspiro[4.5]decane (12 d) showed higher anticonvulsant activity than sodium valproate at dose 0.08 mmol/kg. On the other hand, 4-Amino-N- (1-(cyclohexylcarbamoyl) cyclohexyl)-N-phenylbenzamide (10 h) and 3-Cyclohexyl-1-phenyl-2-(3,4,5-trimethoxyphenyl)-1,3-diazaspiro[4.5]decane (12 d) exhibited higher antinociceptive potential in both intensity and duration than tramadol hydrochloride. The pharmacokinetics of the new compounds were calculated in-silico. Additionally, 3D pharmacophoric model was generated.[a] Prof.
