Quinazolinones, 13.Comm. Synthesis of 3-[2-(2,3-Dihydro-5-phenyl-4-substituted-3H-1,2,4-triazole-3-thione-2-yl)-acetylamino]-2-methyl-4(3H)-quinazolinones and their pharmacological activities
Some 2‐methyl‐3‐triazole‐substituted‐4(3H)‐quinazolinones 3a–f were prepared and tested for their H1‐ and H2‐ antihistaminic activities. In addition these compounds are central nervous system depressants and anticonvulsants. 3e shows highly significant decrease of locomotor activity.
