Calpeptin 是一种有效的、具有细胞穿透性的calpain抑制剂,其对人血小板 Calpain I 的ID50值为40 nM。Calpeptin 也是cathepsin K的抑制剂。
生物活性 | Calpeptin is a potent, cell penetratingcalpaininhibitor, with anID50of 40 nM for Calpain I in human platelets[1]. Calpeptin is also an inhibitor ofcathepsin K[2]. |
IC50& Target | ID50: 40 nM (Calpain I in human platelets)[1]. Cthepsin K[2] |
体外研究 (In Vitro) | Calpeptin (0-100 nM, 24 hours) treatment suppresses the proliferation of both WI38 VA13 and IMR90 cells in a dose-dependent manner. Calpeptin (1000 pg/ml, 24 hours) inhibits IL-6-induced cell proliferation of lung fibroblasts[3].
Cell Proliferation Assay[3] Cell Line: | WI38 VA13 and IMR90 cells | Concentration: | 0-100 nM | Incubation Time: | 24 hours | Result: | Suppressed the proliferation in a dose-dependent manner. |

体内研究 (In Vivo) | Calpeptin with Bleo (0.04 mg/mouse, i.p., 3 times weekly, 28 days) administration significantly inhibits the collagen deposition and increases of calpain activity in the NSC-125066 treated mouse lung tissues[3].
Animal Model: | C57BL/6 female mice (Eight-week-old)[3]. | Dosage: | 0.04 mg/mouse. | Administration: | Intraperitoneally three times weekly for 28 days (together with Bleo). | Result: | Inhibited the collagen deposition and increase of calpain activity in the NSC-125066 treated mouse lung tissues. |
