SSK1
Based on 3 publication(s) in Google Scholar
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.

Biological Activity
SSK1 (0.5 μM; 12-72 hours) activates the phosphorylation levels of both p38 MAPK and MKK3/MKK6 in senescent cells. SSK1 kills senescent cells through the activation of the p38 MAPK signaling pathway. SSK1 is able to induce mitochondrial DNA damage in senescent cells[1].
?
SSK1 (0.01-1 μM; 3 days) selectively and potently eliminates β-galactosidase-positive senescent cells within a wide therapeutic window[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:Primary mouse fibroblasts
-
Concentration:0.5 µM
-
Incubation Time:12 hours, 24 hours, 36 hours, 48 hours, 72 hours
-
Result:Both p38 MAPK and MKK3/MKK6 were activated by phosphorylation in senescent cells.
? In aged mice (20-month-old), SSK1 (0.5 mg/kg; 3 days every 2 weeks for 8 weeks) effectively clears senescent cells in different tissues, decreases the senescence- and age-associated gene signatures, attenuates low-grade local and systemic inflammation, and restores physical function[1].

Animal Model:Mice (3-6-month-old) were subjected to transtracheal injection of Bleomycin[1]
-
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

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
