SAR development of lysine-based irreversible inhibitors of transglutaminase 2 for huntington's disease

We report a series of irreversible transglutaminase 2 inhibitors starting from a known lysine dipeptide bearing an acrylamide warhead. We established new SARs resulting in compounds demonstrating improved potency and better physical and calculated properties. Transglutaminase selectivity profiling and in vitro ADME properties of selected compounds are also reported.

Dipeptidyl aspartyl fluoromethylketones as potent caspase inhibitors: SAR of the N-protecting group

The synthesis and biological evaluation of a group of N-protected Val-Asp-fmk as caspase inhibitors is reported. This article describes the synthesis and biological evaluation of a group of N-protected Val-Asp-fmk as caspase inhibitors. The protecting group was found to contribute to caspase-3 inhibiting activity, and compounds with a large group such as Cbz are more active than compounds with a small group such as Ac. Compounds with more hydrophobic protecting groups were found to be more active in cell apoptosis protection assays, probably due to increased cell permeability. MX1122, 2,4-di-Cl-Cbz-Val-Asp-fmk, is identified as a potent broad-spectrum caspase inhibitor and is selective for caspases versus other proteases, with good activity in the cell apoptosis protection assays as well as good efficacy in the mouse liver apoptosis model.

Non-phosgene synthesis of benzyl chloroformate (CbzCl)

A novel synthetic method for benzyl chloroformate (CbzCl) using carbon monoxide or carbonyl sulfide as a carbonyl source was established. Benzyl chloroformate was successfully synthesized by the chlorination using sulfuryl chloride of S-methyl O-benzyl carbonothioate, which was prepared by the carbonylation of benzyl alcohol with carbon monoxide and sulfur (or carbonyl sulfide) in the presence of DBU (1,8-diazabicyclo[5.4.0]undec-7-ene) followed by esterification using methyl iodide.
