摘要:
Condensation of 1- and 3-hydroxy-7,8,9,10-tetrahydrobenzo[c]chromen-6-ones with substituted 1,1diaminomethanes produced Mannich bases containing a dialkylaminomethyl group in the 2- and 4-positions of 7,8,9,10-tetrahydrobenzo[c]chromen-6-one. Pharmacological screening of 2-chloro-3-hydroxy-4-(1-pyrrolidinylmethyl)-7,8,9,10-tetrahydro-6H-benzo[c]chromen-6-one in Wistar rats showed that it possesses low toxicity and acts as a stimulant of the central and peripheral nervous systems with indications of neuroleptic and tranquilizing activities.
