The retinoic acid receptor-related orphan receptor γt (RORγt) is an important nuclear receptor that regulates the differentiation of Th17 cells and production of interleukin 17(IL-17). RORγt agonists increase basal activity of RORγt and could provide a potential approach to cancer immunotherapy. Herein, hit compound 1 was identified as a weak RORγt agonist during in-house library screening. Changes in LHS core of 1 led to the identification of tetrahydroquinoline compound 6 as a partial RORγt agonist (max. act. = 39.3%). Detailed structure-activity relationship on substituent of the LHS core, amide linker and RHS arylsulfonyl moiety was explored and a novel series of tetrahydroquinolines and benzomorpholines was discovered as potent RORγt agonists. Tetrahydroquinoline compound 8g (EC50 = 8.9 ± 0.4 nM, max. act. = 104.5%) and benzomorpholine compound 9g (EC50 = 7.5 ± 0.6 nM, max. act. = 105.8%) were representative compounds with high RORγt agonistic activity in dual FRET assay, and they showed good activity in cell-based Gal4 reporter gene assay and Th17 cell differentiation assay (104.5% activation at 300 nM of 8g; 59.4% activation at 300 nM of 9g). The binding modes of 8g and 9g as well as the two RORγt inverse agonists accidentally discovered were also discussed.

3-Mercapto-(4H)-1,2,4-triazole has been synthesized from 1-formylthiosemicarbazide. Different N-substituted β-chloropropionamides have been prepared by reacting substituted amines with β- chloropropionylchloride. Different Nsubstituted β-chloropropionamides have been condensed with 3-mercapto-(4H)-1,2,4-triazole in basic medium to obtain various 3-(N-substituted carboxamidoethylthio)-(4H)-1,2,4-triazoles. The structure of the synthesized compounds are confirmed by IR, 1H NMR spectra and elemental analysis. All the compounds have been screened for their analgesic, anti-inflammatory and anxiolytic activity.

In this study, by combining anilide and N', N'-phthaloylglycinamide pharmacophores which are known to produce potent anticonvulsant compounds, sixteen omega-phthalimido-N-phenylacetamide and propionamide derivatives bearing substituents at positions 2 or 2, 6 on N-phenyl ring have been synthesized. The structural confirmation of the title compounds was achieved by interpretation of spectral and analytical data. The anticonvulsant activity of the title compounds was determined against maximal electroshock seizure at 100 mg/kg dose level in mice. The preliminary screening results indicated that omega-phthalimido-N-phenylacetamide and propionamide nuclei have pronounced anticonvulsant activity against maximal electroshock seizure.
