ABSTRACT:
Novel nitrogen-containing heterocyclic compounds shown by the formula ##STR1## wherein Y represents an oxygen atom, a sulfur atom, or a group shown by ##STR2## (wherein m is 1 or 2); n represents 0 or 1; R.sub.1 and R.sub.4, which may be the same or different, each represents a hydrogen atom, a lower alkyl group, or a lower alkenyl group; R.sub.2 and R.sub.3, which may be the same or different, each represents a hydrogen atom, a hydroxyl group, a lower alkanoyloxy group, a lower alkyl group or a lower alkenyl group; said R.sub.2 and R.sub.3 may further form together a double bond; R.sub.5 and R.sub.6, which may be the same or different, each represents a hydrogen atom, a halogen atom, a hydroxyl group, a nitro group, an amino group, a lower alkoxy group, a mono or di lower alkylamino group, or a lower alkyl group; said R.sub.5 and R.sub.6 may further form together a lower alkylenedioxy group; and R.sub.7 represents a hydrogen atom, a halogen atom, a lower alkanoyl group, a phenyl group, a phenyl lower alkyl group, a lower alkyl group, a hydroxy lower alkyl group, a di lower alkylamino lower alkyl group, a pyrrolidino lower alkyl group, a piperidino lower alkyl group, a morpholino lower alkyl group, or a 4-lower alkylpiperazino lower alkyl group;
