The present invention relates to novel heterocyclically fused diaryldihydropyrimidine derivatives, to processes for their preparation, to their use alone or in combination for the treatment and/or prevention of diseases and also to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of disorders of the lung and the cardiovascular system.
Novel 4-arylpyrimidine derivatives were synthesized by the oxidation of 4-aryl-1, 4-dyhydropyrimidines, and their effects on anti-anoxic (AA) activity in mice and anti-lipid peroxidation (ALP) activity in rat mitochondria were investigated. Among these compounds, ethyl 6-methyl-2-phenyl-4-(4-pyridyl)-5-pyrimidinecarboxylate (4b) has AA activity (10mg/kg, i.p.) and ethyl 6-methyl-4-(3-nitrophenyl)-2-phenyl-5-pyrimidinecarboxylate (4f) has ALP activity (73% inhibition at 10<-5>g/ml). The latter compound (100mg/kg, i.p.) was also effective on arachidonate-induced cerebral edema in rats with comparable potency to that of vitamin E.

Humanneutrophilelastase (HNE) is a key driver of inflammation in many cardiopulmonary and systemic inflammatory and autoimmune conditions. Overshooting high HNE activity is the consequence of a disrupted protease–antiprotease balance. Accordingly, there has been an intensive search for potent and selective HNE inhibitors with suitable pharmacokinetics that would allowing oral administration in patients
