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

Bioorg Med Chem Lett. 2007 Nov 1;17(21):5831-5. doi: 10.1016/j.bmcl.2007.08.040. Epub 2007 Aug 23.

Abstract

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.
