calpain inhibitor xii

(Rac)-Calpain Inhibitor XII is a reversible and selective inhibitor targeting calpain I (μ-calpain) with a Ki value of 19 nM. It exhibits lower affinities for calpain II (m-calpain, Ki=120 nM) and cathepsin B (Ki=750 nM). This compound is potentially useful for investigating calpains' involvement in various processes such as neutrophil chemotaxis, neuronal signaling, and cardiac responses to injury [1].

Calpain Inhibitor-1 (compound 36) is a highly potent and selective inhibitor of Calpain 1 (Cal1), which is a cysteine protease. It exhibits an IC50 value of 100 nM and a Ki value of 2.89 μM.

Calpain Inhibitor XI, a reversible covalent inhibitor of calpain-1, is utilized in the research of neurodegenerative disorders.

Calpain Inhibitor V (Mu-Val-HPh-FMK) is a cell-permeable, irreversible calpain inhibitor with demonstrated anti-chlamydial activity [1].

Calpain Inhibitor-2 is a lipophilic calpain inhibitor, and they showed moderate to good anti-proliferative effects in vitro compared to melanoma cell lines (A-375 and B-16F1) and PC-3 prostate cancer cells. was able to inhibit the invasion of 80% of DU-145 cells.
