| abstract | Novel compound of the general formula: <CHEM> wherein R<1> stands for a hydrogen atom, an optionally substituted lower alkyl group or a halogen atom; R<2> and R<3> respectively stand for a hydrogen atom or an optionally substituted lower alkyl group, provided that either R<2> or R<3> is a hydrogen atom, the other being an optionally substituted lower alkyl group, or R<2> and R<3> may, taken together with the adjacent -C=C- group, form a 5- to 7-membered ring; X stands for an oxygen atom or S(O)p (p stands for an integer from 0 to 2; Y stands for a group of the formula: <CHEM> (R<4> and R<5> respectively stand for a hydrogen atom or an optionally substituted lower alkyl group) or a divalent group derived from an optionally substituted 3- to 7-membered homocyclic or heterocyclic ring; R<6> and R<7> each stands for a hydrogen atom, an optionally substituted lower lakyl group, an optionally substituted cycloalkyl group or an optionally substituted aryl group, or R<6> and R<7> may, taken together with the adjacent nitrogen atom, form an optionally substituted nitrogen-containing heterocyclic group; m stands for an integer from 0 to 4; and n stands for an integer from 0 to 4, or a salt thereof, which has excellent anti-.PAF activities, and is of value as an antiasthmatic agent, and their production, intermediates and pharmaceutical compositions. |
