title: Dual M3 antagonists-PDE4 inhibitors. Part 2: Synthesis and SAR of 3-substituted azetidinyl derivatives.
abstract: Introduction of 3-substituted azetidinyl substituents onto the 4,6-diaminopyrimidine scaffold allowed the improvement of PDE4 inhibiting activities. Preliminary in vivo activity in pulmonary inflammation models is reported.
