Synthesis, structure-activity relationships, and pharmacological profile of 9-amino-4-oxo-1-phenyl-3,4,6,7-tetrahydro[1,4]diazepino[6,7,1-hi]indoles: Discovery of potent, selective phosphodiesterase type 4 inhibitors

The synthesis, structure-activity relationships, and biological properties of a novel series of potent and selective phosphodiesterase type 4 (PDE4) inhibitors are described. These new aminodiazepinoindoles displayed in vitro PDE4 activity with submicromo

Diazepinoindoles as phosphodiesterase 4 inhibitors

Diazepinoindoles of formula (I), STR1 wherein A is mono- to trisubstituted aryl or heteroaryl, and B is an --OR1 or --NR2 R3 group where R1, R2 and R3 are particularly hydrogen, and racemic
