Strategies toward improving the brain penetration of macrocyclic tertiary carbinamine BACE-1 inhibitors

This letter describes replacements for the P3 amide moiety present in previously reported tertiary carbinamine macrolactones. Although P-gp efflux issues associated with these amide-macrolactones were solved and full brain penetration was measured in one case, potency was compromised in the process.
