Description
Curator's Comment: description was created based on several sources, including http://www.4sc.de/wp-content/uploads/160621__4SC_CompanyPres_Citi.pdf

4SC-202 is an epigenetic oncology compound with a unique therapeutic profile, which was developed by biotechnology company: 4SC. 4SC-202 works as a selective inhibitor of LSD1 (lysine-specific demethylase 1) and HDAC (histone deacetylase) 1, 2 and 3. 4SC-202 also strengthens the endogenous immune response to cancer tissue. This compound demonstrated successfully completed Phase I of the clinical study, where it was proved safe and well tolerated in patients with advanced hematologic cancer. In addition, 4SC-202 shows substantial anti-tumor activity in a broad range of cancer cell lines including hepatocellular carcinoma, Urothelial Carcinoma Cell Lines and colorectal cancer.

Curator's Comment: 4SC-202 treatment induced potent cytotoxic and proliferation-inhibitory activities against established hepatocellular carcinoma (HCC) cell lines (HepG2, HepB3, SMMC-7721) and patient-derived primary HCC cells. Further, adding 4SC-202 in HCC cells activated mitochondrial apoptosis pathway, which was evidenced by mitochondrial permeability transition pore (mPTP) opening, cytochrome C cytosol release and caspase-3/-9 activation. 4SC-202 induced apoptosis signal-regulating kinase 1 (ASK1) activation, causing it translocation to mitochondria and physical association with Cyp-D. This mitochondrial ASK1-Cyp-D complexation appeared required for mediating 4SC-202-induced apoptosis activation. ASK1 stable knockdown by targeted-shRNAs largely inhibited 4SC-202-induced mPTP opening, cytochrome C release, and following HCC cell apoptotic death.
