Expansion/bioisosteric replacements/scaffold hopping of an early lead JAG-UCB-a3ef7265-20. Simple alkyl replacements for the c-Pr group to help inform the design of triazole replacements for which the corresponding c-Pr monomers may not be available. Hydroxy ethyl analog may assist solubility and by H-bond to Glu 166 or Asn 142.
