Synthesis and initial results for MAO-B inhibition by new N-propargyl-3-pyrrol-1-ylindanamine derivatives, analogues of rasagiline.

The syntthesis of new N-propargyl-3-pyrrol-1-ylindanamine derivatives, analogues of rasagiline, is described in ten steps starting from the corresponding arylaldehydes via the corresponding cis-3-pyrrol-1-ylindanamines. The cis-configuration of some intermediates has been established using X-ray analysis and NOE experiments. The new N-propargyl-3-pyrrol-1-ylindanamine derivatives were evaluated for their potential MAO-B inhibitor activity in an in vivo model of MPTP-induced Parkinsonism in mice with respect to the potent MAO-B inhibitor rasagiline.
