Q is lower alkyl, especially methyl;
R is H or lower alkyl;
X is imino, oxa or thia;
Y is lower alkyl or, especially, aryl, heteroaryl or unsubstituted or substituted cycloalkyl; and
Z is amino, mono- or di-substituted amino, halogen, alkyl, substituted alkyl, hydroxy, etherified or esterified hydroxy, nitro, cyano, carboxy, esterified carboxy, alkanoyl, carbamoyl, N-mono- or N,N-di-substituted carbamoyl, amidino, guanidino, mercapto, sulfo, phenylthio, phenyl-lower alkylthio, alkylphenylthio, phenylsulfinyl, phenyl-lowe
