The invention relates to a method for preventing or treating a disease or disorder that is associated with the MrgX2 receptor. The invention also relates to MrgX2 antagonists and physiologically acceptable salts thereof. The invention also relates to pharmaceutical compositions and dosage forms comprising an MrgX2 antagonist.
Gas-phase pyrolysis of aminomethylene Meldrum’s acidderivatives gave quinolinones and/or amines depending on the -nature of arylamino moiety. Effect of substituent on reaction rate and nature of pyrolysis products supports the suggested intramolecular nucleophilic substitution reaction via initially formed keteneamine intermediate.
Electron-rich and electron-deficient anilinomethylene derivatives of Meldrum’s acid cyclize equally efficiently to quinolin-4-ones via imidoylketene intermediates under flash vacuum pyrolysis (FVP) conditions.
The present invention relates to an electronic device comprising anode, cathode and at least one organic layer which comprises a compound of the formula (I) to (IV). The invention furthermore encompasses the use of compounds of the formula (I) to (IV) in an electronic device and to a compound of the formula (Ic) to (IVc).
