Liu, Dachuan published the artcileDesign, synthesis and biological evaluation of benzo[d]thiazole with dimethylpyrazole derivatives, COA of Formula: C8H6ClF3, the publication is Asian Pacific Journal of Cancer Prevention (2019), 20(11), 3487-3495, database is CAplus and MEDLINE.
A series of new benzothiazole derivatives containing dimethylpyrazole I [R = H, n-pentyl, benzyl, etc.] were synthesized and evaluated for their anticonvulsant activity, neurotoxicity and cytotoxicity by using the maximal electroshock (MES), rotarod neurotoxicity (TOX) and MTT colorimetric assay. Among the compounds studied, four compounds I [R = Bu, n-pentyl, 2-fluorobenzyl, 2,6-dichlorobenzyl] showed better anticonvulsant than the others at 300 mg/kg and they also showed anticonvulsant activity at the dose of 100 mg/kg. All the synthetic compounds I showed lower neurotoxicity and little cytotoxicity, so that the compounds, which with better activities, also had higher protective index. In particular, the compound I [R = 2-fluorobenzyl] showed better activity with an ED50 value of 160.4 mg/kg and higher protective index (PI) values of 2.74 in the MES test than the standard drugs sodium valproate, which used as pos. controls in this study. After that the compound I [R = 2-fluorobenzyl] demonstrated antagonistic activity against seizures induced by pentylenetetrazol, which proved compound I [R = 2-fluorobenzyl] may be exert activity through effecting GABAergic neurotransmission.
