Satratoxin H
Based on 1 Customer Validation
Satratoxin H is a toxic metabolite of Stachybotrys atra. Satratoxin H induces caspase-3 and PARP cleavage via p38 MAPK and JNK pathways, stimulates JNK, ERK, and p38 MAPK phosphorylation, and activates JNK and p38 MAPK in a glutathione-sensitive manner. Satratoxin H induces DNA double-stranded breaks, apoptotic body formation, intracellular reactive oxygen species generation, and endoplasmic reticulum stress via ATF6, PERK, and IRE1 pathways. Satratoxin H can be used for the research of central nervous system disorders and melanoma.

Satratoxin H (50 nM; 0.5-24 hr) induces apoptosis in PC12 cells via p38 MAPK/JNK-mediated cleavage of caspase-3 and subsequent PARP cleavage[1].
Satratoxin H (5-20 nM; 24 hr) induces chromosome damage in PC12 cells[1].
Satratoxin H (5-50 nM; 12-24 hr) induces DNA double-stranded breaks in PC12 cells, as indicated by increased γH2AX staining at 50 nM (12 and 24 hours) and 5, 10, and 20 nM (24 hours)[1].
Satratoxin H (5-20 nM; 24 hr) does not induce DNA single-stranded breaks in PC12 cells at concentrations of 5, 10, and 20 nM after 24-hour exposure[1].
Satratoxin H (10-100 nM; 6-48 h) induces time- and concentration-dependent cytotoxicity in undifferentiated PC12 cells[2].
Satratoxin H (50 nM; 24 h) induces apoptotic morphological changes (condensed chromatin, nuclear fragmentation, apoptotic bodies) in undifferentiated PC12 cells after 24 h, with some concurrent necrosis[2].
Satratoxin H (50 nM; 18-24 h) increases the percentage of apoptotic undifferentiated PC12 cells to 4.85% after 18 h and 13.25% after 24 h, as measured by flow cytometric subdiploid DNA content analysis[2].
Satratoxin H (5-100 nM; 0.5-6 h) induces time- and concentration-dependent phosphorylation of p38 MAPK, ERK1/2, and JNK in undifferentiated PC12 cells, and co-treatment with antioxidants reduces satratoxin H-induced p38 MAPK phosphorylation[2].
Satratoxin H (1-100 nM; 6-48 h) reduces PC12 cell viability in a concentration- and time-dependent manner[3].
Satratoxin H (1 nM-50 nM; 24 h) inhibits B16F10 mouse melanoma cell proliferation with an IC50 of approximately 20 nM and completely suppresses colony formation at 50 nM[4].
Satratoxin H (1 nM-50 nM; 24 h) induces caspase-dependent apoptosis in B16F10 mouse melanoma cells by upregulating pro-apoptotic Bax and cleaved caspase-3, and downregulating anti-apoptotic Bcl-2, in a concentration-dependent manner[4].
Satratoxin H (1 nM-50 nM; 24 h) induces concentration-dependent activation of endoplasmic reticulum stress pathways (IRE1, PERK, ATF6) and upregulates pro-apoptotic Bim and CHOP mRNA levels in B16F10 mouse melanoma cells[4].
Satratoxin H (1 nM-50 nM; 2 h) induces concentration-dependent intracellular ROS production in B16F10 mouse melanoma cells, and this ROS generation is essential for its cytotoxic effects[4].
Satratoxin H (50 nM; 10 min) induces mitochondrial ROS production in B16F10 mouse melanoma cells, and this effect is dependent on endoplasmic reticulum stress[4].
