The synthesis and biological evaluation of a novel series of indole PDE4 inhibitors I

Bioorg Med Chem Lett. 1998 Jul 21;8(14):1867-72. doi: 10.1016/s0960-894x(98)00324-2.

Abstract

This communication describes the synthesis and in vitro evaluation of a novel potent series of phosphodiesterase type (IV) (PDE4) inhibitors. The compounds described contain an indole moiety which replaces the 'rolipram-like' 3-methoxy-4-cyclopentoxy motif. Several of the compounds presented possess low nanomolar IC50's for PDEIV inhibition. In vivo activities determined from measurement of serum TNF-alpha levels in LPS challenged mice (mouse endotoxemia model) are also reported.
