Cathepsin B (CtsB) is a lysosomal cysteine proteinase that is specifically translocated to the extracellular milieu during cancer progression. The development of a lipidated CtsB inhibitor incorporated into the envelope of a liposomal nanocarrier (LNC-NS-629) is described. Ex vivo and in vivo studies confirmed selective targeting and internalization of(More)
Cathepsin C is a papain-like cysteine protease with dipeptidyl aminopeptidase activity that is thought to activate various granule-associated serine proteases. Its exopeptidase activity is structurally explained by the so-called exclusion domain, which blocks the active-site cleft beyond the S2 site and, with its Asp 1 residue, provides an anchoring point(More)
An extensive structure-activity relationship study with the template of 2-(4-phenoxyphenylsulfonylmethyl)thiirane (1), a potent and highly selective inhibitor for human gelatinases, is reported herein. Syntheses of 65 new analogs, each in multistep processes, allowed for exploration of key structural components of the molecular template. This study reveals(More)
