摘要:
The cyclic amide derivative is defined by the formula (I) or a salt thereof: R1-(CH2)n-Z in which R1 is a group derived from a cyclic amide compound, substituted or unsubstituted, n is zero or an integer of 1 to 10 and Z is ##STR1## R2 being an aryl, a substituted aryl, a cycloalkyl or a heterocyclic group, m being an integer of 1 to 6, R3 being hydrogen or a lower alkyl, R4 being an aryl or a substituted aryl, a cycloalkyl or a heterocyclic group, p being an integer of 1 to 6, provided that the cyclic amide compound is quinazoline-on or quinazoline-dion, R2 and R4 are neither aryl nor substituted aryl. The cyclic amide compound is pharmacologically effective to prevent and treat diseases due to insufficiency of the central choline functions.

摘要:
Process for preparing 3-chloroanthranilic alkyl esters by reacting 3-chloroanthranilic acid, in an inert solvent, with from 0.8 to 5 parts by weight of phosgene, and reacting the 3-chloroisatoic anhydride which is formed with an alkanol, where appropriate in the presence of an esterification catalyst, to give the 3-chloroanthranilic alkyl ester.
摘要:
Pyrazolo[5,1-b]quinazolones are prepared by reacting isatoic anhydrides with pyrazolones at from 100.degree. to 180.degree. C. in an inert organic solvent with simultaneous azeotropic removal of the water formed in the course of the reaction.
摘要:
A 4H-3,1-benzoxazin-4-one compound of the formula (I): ##STR1## wherein R is a hydrogen atom or alkyl radical, A is an amino acid residue or a peptide having 2 to 3 amino acid residues, which amino acid residue may have a side chain thereof protected by a protective radical, X is an alkyl, fluoroalkyl, OR.sup.1 or NHR.sup.1 radical wherein R.sup.1 is an alkyl radical, and Y is a protective radical for an amino radical, and salts thereof, exhibit an excellent inhibitory activity against serine proteases, especially against human leukocyte elastase, and thus are useful as an effective component of a medicine for inhibiting elastase.
摘要:
