wherein R' stands for a lower alkyl group, R 2 stands for an optionally protected carboxyl group and X stands for a halogen or a salt thereof, has excellent anti-asthmatic and antiinflammatory activities and therefore is useful as an antiasthmatic or antiinflammatory agent for a mammalian animal.
摘要:
A compound of the formula wherein R is a lower alkyl group, R 0 is hydrogen or an acyl group, R 1 and R 2 are lower alkyl groups which may optionally be substituted or wherein R 1 and R 2 are combined to form a butadienylene group which may optionally be substituted, R 3 and R 4 are hydrogen or alkyl groups which may 'optionally be substituted or wherein R 3 and R 4 are combined to form a polymethylene group, and R 5 is a lower alkyl, aromatic or heterocyclic group which may optionally be substituted or a pharmaceutically acceptable salt thereof, exerts cardiovascular system improving action and antiallergic action and can be used as pharmaceutics, e.g. antithromotics, antiallergic agents etc.
wherein R' stands for a lower alkyl group, R 2 stands for an optionally protected carboxyl group and X stands for a halogen or a salt thereof, has excellent anti-asthmatic and antiinflammatory activities and therefore is useful as an antiasthmatic or antiinflammatory agent for a mammalian animal.
摘要:
The compound of the formula wherein R 1 is hydrogen, fluorine, methoxy or trifluoromethyl, R 2 is hydrogen or methyl, R 3 is a C 3-8 straight-chain or branched alkyl, and n denotes 0 or 1, or their pharmacologically acceptable salts is novel and useful for prophylaxis and therapy of digestive ulcers (e.g. gastric ulcer, duodenal ulcer) and gastritis.
R is methyl or methoxy and Y is formyl, carboxyl, an alkoxycarbonyl having 2 to 5 carbon atoms, carbamoyl, a mono- or dialkylcarbamoyl whose alkyl moiety has 1 to 4 carbon atoms or carbamoyloxymethyl, or their hydroquinone-form compounds, or pharmaceutically acceptable salts thereof, have useful physiological activities such as antiasthmatic and antiallergic activities.
