生物活性:
SSK1, a senescence-specific killing compound, is a β-galactosidase-targeted proagent attenuates inflammation. SSK1 is activated by lysosomal β-galactosidase and selectively killed senescent cells through the activation of p38 MAPK and induction of apoptosis.

体内研究:
SSK1 (0.5 mg/kg;腹腔注射;每周两天;持续 4 周) 可消除肺损伤小鼠的衰老细胞并降低衰老相关标记物。小鼠 (20 个月大),SSK1 (0.5 mg/kg;每 2 周 3 天,持续 8 周) 有效清除不同组织中的衰老细胞,减少衰老和年龄相关基因特征,减弱低级别局部和全身炎症,恢复身体机能。Animal Model:Mice (3-6-month-old) were subjected to transtracheal injection of Bleomycin
Dosage:0.5 mg/kg
Administration:Intraperitoneally injection; two days every week; for four weeks
Result:SSK1 significantly reduced the percentage of SA-β-gal-positive cells in lung by 3.8-fold compared with that in vehicle-treated lung-injured mice

体外研究:
SSK1 (0.5 μM;12-72 小时) 激活衰老细胞中 p38 MAPK 和 MKK3/MKK6 的磷酸化水平。SSK1 通过激活 p38 MAPK 信号通路杀死衰老细胞。SSK1 能够在衰老细胞中诱导线粒体 DNA 损伤。 SSK1 (0.01-1 μM;3 天) 选择性并有效地消除广泛范围内的 β-半乳糖苷酶阳性衰老细胞处理窗。
