SC13
Based on 1 publication(s) in Google Scholar
SC13 is an orally active, selective Flap structure-specific endonuclease 1 (FEN1) inhibitor and mu opioid receptor (MOR) activator. SC13 impairs DNA damage repair and induces apoptosis in cancer cells. SC13 activates cGAS-STING signaling, increases chemokine secretion, and promotes CAR-T cell infiltration at solid tumour sites. SC13 can be used for the research of solid tumours and pain.

SC13 (20 μM; 48 h) induces DNA double-strand break accumulation and cytoplasmic dsDNA leakage in HeLa, MCF-7, and SKOV-3 human cancer cells[1].
SC13 (20 μM; 48 h) activates the cGAS-STING pathway and increases chemokine (CCL5, CXCL10) and IFN-β expression in HeLa, MCF-7, and SKOV-3 human cancer cells, dependent on STING signalling[1].
SC13 (20 μM; 48 h) induces HeLa, MCF-7, and SKOV-3 cells to secrete chemokines that promote MSLN CAR-T cell migration via a TBK1-dependent mechanism[1].
SC13 (20 μM; 48 h) induces mild DNA damage but does not impair proliferation, CAR expression, or cytotoxic function of MSLN CAR-T cells[1].
SC13 potently inhibits cAMP production in human mu-opioid receptor-expressing HEK-T cells with an EC50 of 7.25 nM and maximum efficacy[2].
SC13 recruits β-arrestin2 in human mu-opioid receptor-expressing HTLA cells with low potency (EC50 = 11000 nM) and moderate efficacy[2].
SC13 acts as a partial agonist for Gi-1 G-protein activation in human mu-opioid receptor-expressing cells, with high selectivity for MOR over DOR and KOR[2].

Cell Line:MSLN CAR-T cells, HeLa, MCF-7, SKOV-3 human cancer cell lines
-
Concentration:20 μM

Result:Significantly increased the number of migrating MSLN CAR-T cells compared to medium from vehicle-treated tumour cells; this effect was blocked by pre-treatment of tumour cells with the TBK1 inhibitor Amlexanox.
Increased secretion of CCL5 and CXCL10 in the supernatant of SC13-treated tumour cells.
SC13 (1-15 mg/kg; s.c. or p.o.; single dose; 10 mg/kg) produces MOR-dependent antinociception in mice with an ED50 of 3.05 mg/kg s.c., and maintains efficacy via oral administration[2].
SC13 (15 mg/kg; s.c.; daily; 2 days) does not induce reward or dysphoria in Mus musculus[2].
SC13 (15 mg/kg; s.c.; single dose) does not inhibit gastrointestinal transit in mice[2].
SC13 (45 mg/kg; s.c.; single dose) does not induce respiratory depression or hyperlocomotion in mice[2].
