Saxagliptin (BMS-477118)

Calpeptin^New

Calpeptin is a potent, cell-permeable calpain inhibitor with ID50 of 52 nM, 34 nM, 138 nM, and 40 nM for Calpain I (porcine erythrocytes), Calpain II (porcine kidney), Papainb, and Calpain I (human platelets), respectively. Calpeptin attenuates apoptosis and intracellular inflammatory changes in muscle cells.

Marimastat (BB-2516)^New

Marimastat (BB-2516, TA2516) is a broad spectrum matrix metalloprotease (MMP) inhibitor for MMP-9, MMP-1, MMP-2, MMP-14 and MMP-7 with IC50 of 3 nM, 5 nM, 6 nM, 9 nM and 13 nM, respectively. Phase 3.

Ledipasvir (GS5885)^New

Ledipasvir (GS5885) is a HCV NS5A polymerase inhibitor, used for the treatment of hepatitis C virus infection.

Sitagliptin phosphate monohydrate

Sitagliptin phosphate monohydrate (MK-0431) is a potent inhibitor of DPP-IV with IC50 of 19 nM in Caco-2 cell extracts.

Linagliptin (BI-1356)

Linagliptin (BI-1356) is a highly potent, selective DPP-4 inhibitor with IC50 of 1 nM and exhibits a 10,000-fold higher selectivity for DPP-4 than for other dipeptidyl peptidases such as DPP-2, DPP-8, and DPP-9. Linagliptin activates glomerular autophagy in a model of type 2 diabetes. DPP4 mediates ferroptosis in TP53-deficient CRC cells.

Vildagliptin (LAF-237)

Vildagliptin (LAF-237) inhibits DPP−4 with IC50 of 2.3 nM.

Alogliptin (SYR-322) benzoate

Alogliptin (SYR-322) benzoate is a potent, selective inhibitor of DPP-4 with IC50 of <10 nM, exhibits greater than 10,000-fold selectivity over DPP-8 and DPP-9.

Trelagliptin

Trelagliptin (SYR-472) is a highly selective, long-acting DPP-4 inhibitor. Phase 3.

MG-132

MG132 (Z-Leu-Leu-Leu-al) is a potent cell-permeable proteasome and calpain inhibitor with IC50s of 0.1 μM and 1.2 μM for the inhibition of proteasome and calpain, respectively. MG132 activates autophagy and induces apoptosis in tumor cells.

Bortezomib (PS-341)

Bortezomib (PS-341, Velcade, LDP-341, MLM341, NSC 681239) is a potent 20S proteasome inhibitor with K_i of 0.6 nM. It exhibits favorable selectivity towards tumor cells over normal cells. Bortezomib (PS-341) inhibits NF-κB and induces ERK phosphorylation to suppress cathepsin B and inhibit the catalytic process of autophagy in ovarian cancer and other solid tumors.
