In Vitro:

SSTC3 (0-1μM, 5 days) decreases the viability of HCT116 cells in an on-target manner. This capacity is significantly reduced when the mutant CTNNB1 allele driving its carcinogenic properties is deleted.


In Vivo:

SSTC3 can be maintained for 24 hours after treatment.

SSTC3 (25 mg/kg, ip once daily for 8-12 days) suppresses the growth of colorectal carcinoma in CD-1 mice.

SSTC3 (10 mg/kg, ip once daily for 1 month) inhibits the growth of Apc mutation-driven tumors.
