TASIN-1
Based on 1 Customer Validation
TASIN-1 is a selective inhibitor of truncated APCTR (adenomatous polyposis coli gene) that exerts cytotoxic effects by inhibiting cholesterol biosynthesis. TASIN-1 specifically targets colorectal cancer (CRC) cells carrying APC truncated mutations, while having no significant toxicity to wild-type APC cells. TASIN-1 exerts cytotoxic effects by targeting Emopamil binding protein (EBP) to inhibit cholesterol biosynthesis, triggering endoplasmic reticulum (ER) stress, reactive oxygen species (ROS) generation, and JNK-mediated apoptosis, and inhibiting Akt survival signaling. TASIN-1 can be used to prevent and intervene in APC mutant colorectal cancer.

TASIN-1 selectively inhibits adenomatous polyposis coli truncated (APCTR) in DLD1 cells with IC50=70 nM[1].
TASIN-1 (70 nM; 72 h) significantly inhibits the proliferation of human colon cancer cells DLD1 (APCTR) with IC50 of 70 nM, and has a high selectivity against HCT116 (APCWT) cells with IC50 >50 μM[1].
TASIN-1 (2.5 μM; 7 d) inhibits soft agar colony formation of DLD1 cells, but has no significant effect on HCT116[1].
TASIN-1 (2.5 μM; 2-48 h) reduced the cholesterol synthesis rate and endogenous cholesterol levels in DLD1 cells, but had no effect on HCT116 cells[1].
TASIN-1 (2.5 μM; 24 h) induced the expression of endoplasmic reticulum stress marker CHOP and JNK phosphorylation, and activated caspase 3/7 activity in DLD1 cells, but no significant changes were observed in HCT116 cells[2].

-
Cell Line:DLD1 (APCTR), HCT116 (APCWT)
-
Concentration:0.01-100 μM
-
Incubation Time:72 h
-
Result:Showed an IC50 of 70 nM in DLD1 cells and >50 μM in HCT116 cells, demonstrating >700-fold selectivity for APCTR cells.
TASIN-1 (20, 40 mg/kg; ip; twice weekly; 90 or 100 days) reduces the number and size of colon polyps and inhibits tumor progression in the CPC;Apc mouse genetic colorectal cancer model without significant liver and kidney damage or weight loss[1].

-
Animal Model:Female athymic nude mice (5-6 weeks old, ~20 g) with DLD1/HT29 (APCTR) or HCT116 (APCWT) subcutaneous xenograft model[1]
-
Dosage:40 mg/kg
-
Administration:Intraperitoneal (i.p.) injection, twice daily (bid), 18 days
-
Result:Reduced DLD1 and HT29 tumor volumes by 40%-60% compared to vehicle control, with increased cleaved caspase 3 and PARP in tumor lysates.
Showed no significant growth inhibition against HCT116 tumors.
Tumor histology revealed fragmented nuclei and increased apoptotic cells in treated groups.
