Pulchinenoside E2
Based on 1 Customer Validation
Pulchinenoside E2 is a triterpenoid saponin. Pulchinenoside E2 inhibits the phosphorylation of STAT3 and JAK2, blocks the nuclear translocation and transcriptional activity of STAT3, and suppresses STAT3-dependent mitochondrial oxidative phosphorylation. Pulchinenoside E2 inhibits invasion, migration and autophagy of triple-negative breast cancer cells. Pulchinenoside E2 can be used in research related to triple-negative breast cancer.

Pulchinenoside E2 (0.75-1.5 μM; 24 h) induces lysosomal dysfunction in HS-578T and MDA-MB-231 TNBC cells, characterized by suppressed proteolytic activity, time-dependent degradation of mature CTSD, and lysosomal alkalinization[1].
Pulchinenoside E2 (0.75-1.5 μM; 24 h) dose-dependently increases GFP-LC3B puncta formation and impairs autophagic flux in HS-578T and MDA-MB-231 TNBC cells[1].

Cell Line:HS-578T, MDA-MB-231 TNBC cells
-
Concentration:0.75, 1.5 μM
-
Incubation Time:24 h
-
Result:Dose-dependently increased the number of autophagic puncta and fluorescence intensity of GFP-LC3B in both cell lines.
Dose-dependently increased the LC3II/LC3I ratio and accumulation of the autophagy substrate p62.

Animal Model:M-NSG mice (female, 4-6 weeks old, tail vein injection of MDA-MB-231 cells to induce metastases)[2]
-
Dosage:5 mg/kg; 10 mg/kg
-
Administration:i.p.; alternate days; 30 days
-
Result:Markedly reduced pulmonary and hepatic metastatic lesion numbers and tumor volumes in mice treated with 10 mg/kg compared to controls.
Significantly decreased phosphorylated STAT3 (Tyr705/Ser727) expression in metastatic tumors via immunohistochemical staining.
Accumulated LC3B and p62 in metastatic tumors, consistent with autophagic flux blockade.
Maintained serum AST, ALT, CRE, and BUN levels comparable to controls.
Showed no significant histopathological damage in heart and kidney tissues.
Maintained stable body weight throughout treatment, indicating no overt toxicity.
