CLIK-148
CLIK-148 is a highly selective, irreversible and orally active cysteine protease inhibitor, primarily targeting Cathepsin L. CLIK-148 effectively inhibits the Cathepsin L-dependent degradation of HMG-CoA reductase in the endoplasmic reticulum (ER) membrane. CLIK-148 inhibits the processing of proCCK by Cathepsin L, thereby reducing the production of CCK8 (HY-P0093). CLIK-148 inhibits the degradation of type I collagen by osteoclasts' secreted Cathepsin L, reducing tumor-induced bone metastasis and malignant hypercalcemia. CLIK-148 can be used for the studies of bone metabolism disorders and regulation of neuropeptide processing.

cathepsin L |
CLIK-148 (100 nM-10 μM) at a concentration of 100 nM in rat liver, potently and specifically inhibits Cathepsin L activity, while exhibits almost no inhibition against Cathepsin B and C at 1 μM, and demonstrates only weak inhibition towards Cathepsin S and K at a concentration of 10 μM[1].
CLIK-148 (50 μM, 24 h) inhibits the activity of Cathepsin L, thereby blocking the generation of CCK9 from proCCK and ultimately reducing the production of CCK8 in pituitary AtT-20 cells[2].
CLIK-148 (1-10 nM, 72 h) effectively inhibit the degradation of bone collagen mediated by human and mouse osteoclasts activated by TNF-α[3].
CLIK-148 (100 μM) effectively protects HMG-CoA reductase from pathological degradation in the context of C100 cell necrotic injury[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CLIK-148 (50 mg/kg, p.o., once daily for 7 days) effectively prevents and treats malignant hypercalcemia caused by tumors in mice[3].
CLIK-148 (32-128 mg/kg, p.o. or i.v., once daily for 7 days) effectively inhibit the direct bone metastasis and local bone destruction of colon cancer cells[3].
CLIK-148 (100-200 mg/kg, p.o., once daily for 14 days) specifically inhibits the process by which cancer cells metastasize through the bloodstream to the bones in mice[3].
