This invention relates to peptidyl compounds of the formulas (I) and (II) active as cathepsin S, a cysteine protease, inhibitors. The compounds are selective, reversible inhibitors of the cathepsin S are therefore useful in the treatment of autoimmune and other diseases. The invention also relates to processes for preparing such compounds and pharmaceutical compositions comprising them.

Barriers to rotation about the central bond of the 1,2,2-trimethylbutyl (triptyl) group, i.e. barriers to rotation of the t-butyl group, are reported for a series of triptyl compounds But–C(CH3)2X, where the atom in X bonded to the triptyl group is an sp2 or sp hybridised carbon. Barriers in some similar compounds are also reported. Results are discussed in terms of the interactions arising during

C elsewhere in the molecule. The compounds of this invention are cholesterol esterase transfer protein inhibitors and possess unique biopharmaceutical and pharmacokinetic properties compared to Compound 1. They may also be used to accurately determine the concentration of Compound 1 in biological fluids and tissues and to determine metabolic patterns of Compound 1 and its isotopologues. The invention further provides compositions comprising these compounds and methods of treating diseases and conditions that are responsive to inhibition of cholesterol esterase transfer protein, alone and in combination with additional agents.
The present invention relates to compounds that modulate various chemokine receptors. These compounds are useful for treating inflammatory and immune diseases.
