• PubMed Abstract: 
  

To study P1-P3 macrocyclizations of previously reported tertiary-alcohol-comprising HIV-1 protease inhibitors (PIs), three new 14- and 15-member macrocyclic PIs were designed, synthesized by ring-closing metathesis, and evaluated alongside with 10 novel linear PIs. Cocrystallized complexes of the macrocyclic PIs and the HIV-1 protease are presented, analyzed, and discussed. The macrocyclic structures exhibited higher activities than the linear precursors with Ki and EC50 values down to 3.1 nM and 0.37 μM, respectively.
