Human transmissible neurodegenerations including Creutzfeldt-Jakob disease are unique, since they are caused by prions, an infectious agent that replicates without nucleic acids but instead by inducing conversion of a host-resident normal prion protein to a misfolded conformational isoform. For pharmacotherapy of these unusual diseases, tricyclic heterocyclic compounds such as quinacrine have been considered, but with ambiguous success in vivo, so far. On the basis of the synergistic antiprion effects of quinacrine and iminodibenzyl derivatives, we introduce a novel class of potential pharmaceuticals representing structural chimeras of quinacrine and imipramine analogues. We describe the chemical synthesis and bioassays of a focused library of these compounds. The most potent target compound 2a revealed an EC50 value of 20 nM determined with a cell model of prion disease, thus substantially improving the antiprion efficacy of quinacrine.

A series of isoindoline analogues with either an indazole (HMR 2934, HMR 2651) or benzisoxazole (HMR 2543) appendage were prepared for the proposed treatment of psychiatric disorders such as obsessive compulsive disorder and attention deficit disorder. The isoindoline compounds were prepared by reduction of the corresponding phthalimides with LiAlH4. One compound was not chiral, and the other two required an enantioselective synthesis. The key step for these optically active analogues involved the coupling by an SN2 process of either a piperazynyl intermediate or a piperdinyl intermediate with methyl 3-benzyloxy-2-trifluoromethansulfonatopropionate. The products for these two analogues had >98% ee. Process improvements led to the multi-kilogram syntheses of each of these compounds.

Pre-clinical evaluation of a potential antipsychotic agent required a convenient synthesis of 3-(1-piperazinyl)-1H-indazole derivatives. Improvements of the original preparation provided a five-step sequence to an unsubstituted piperazine intermediate, with a 67% overall yield. All intermediates were isolated by filtration.
