Arylamine based cathepsin K inhibitors: Investigating P3 heterocyclic substituents
摘要:
A modification of novel cathepsin K inhibitors I was carried out. The structural design was aimed at reducing the lipophilic character of compounds I for obtaining better pharmacokinetic profiles. This modification afforded several less lipophilic compounds with good inhibitory activities and pharmacokinetic profiles, although the enzyme selectivity over cathepsin S was left at issue.

established the requirement for the all-L stereochemistry of the active inhibitor. The early lead inhibitors were very hydrophobic and, therefore, poorly soluble in aqueous solutions. Using the stereospecific route, new compounds were prepared with polar groups at the C- and N-termini. These modifications resulted in more soluble inhibitors that were still potentinhibitors of calpain. Studies of the stability

T-cells, should, in theory, modulate the immune response. The cysteine protease CathepsinS performs a fundamental step in antigen presentation and therefore represents an attractive target for inhibition. Herein, we report a series of potent and reversibleCathepsinSinhibitors based on dipeptidenitriles. These inhibitors show nanomolar inhibition of the target enzyme as well as cellular potency in
“One-pot” preparation of N-(Carbonylamino)amino acids and half-acid/half-ester urea dipeptides directly from α-amio acids

N-(Carbonylamino)amino acids and half-acid/half ester urea dipeptides can be prepared in a “one-pot” sequence directly from α-amino acids by employing TMS as a “transient” protecting group. The 4-step sequence: selective O-silylation of the α-amino acid, transformation of the amino group to the isocyanate, reaction of the isocyanate with an amine or amino acid ester, and mild deprotection using MeOH
