- Discovery of a novel series of guanidinebenzoates as gut-restricted enteropeptidase and trypsin dual inhibitors for the treatment of metabolic syndrome
-
A novel series of guanidinebenzoate enteropeptidase and trypsin dual inhibitors has been discovered and SAR studies were conducted. Optimization was focused on improving properties for gut restriction, including increased aqueous solubility, lower cellular permeability, and reduced oral bioavailability. Lead compounds were identified with efficacy in a mouse fecal protein excretion study.

- An expeditious synthetic route to proteomimetic foldamers
-
α-Helix proteomimetics such as oligobenzamides have been shown to successfully inhibit a broad array of protein-protein interactions (PPIs) mediated by α-helices. Here we report the synthesis of a protected oligobenzamide intermediate, which can be selectively deprotected and alkylated with desired side chains to rapidly afford a library of α-helix proteomimetics.

- Synthesis of highly functionalized oligobenzamide proteomimetic foldamers by late stage introduction of sensitive groups
-
α-Helix proteomimetics represent an emerging class of ligands that can be used to inhibit an array of helix mediated protein-protein interactions. Within this class of inhibitor, aromatic oligobenzamide foldamers have been widely and successfully used. This manuscript describes alternative syntheses of these compounds that can be used to access mimetics that are challenging to synthesize using previously described methodologies, permitting access to compounds functionalized with multiple sensitive side chains and accelerated library assembly through late stage derivatisation.

- A mild deprotection strategy for allyl-protecting groups and its implications in sequence specific dendrimer synthesis
-
A mild deprotection strategy for allyl ethers under basic conditions in the presence of a palladium catalyst is described. Under these conditions, aryl allyl ethers can be cleaved selectively in the presence of alkyl allyl ethers. These conditions are also effective in the deprotection of allyloxycarbonyl groups. The utility of the current methodology in sequence specific dendrimer synthesis is demonstrated.
