  3. Sulindac sulfone

Sulindac sulfone is an orally active metabolite of Sulindac (HY-B0008). Sulindac sulfone activates PPARγ and drives transcriptional induction of SSAT by binding to the PPRE-2 element. Sulindac sulfone induces Apoptosis. Sulindac sulfone negatively regulates the function of VDAC1/2 to inhibit the mTORC1 pathway, reduces Cyclin D1 levels, and induces G1 cell cycle arrest in colon cancer cells. Sulindac sulfone exerts colon cancer preventive effects through a COX-independent mechanism. Sulindac sulfone can be used in research related to colon cancer.

In Vitro

Sulindac sulfone (50-600 μM; 1-6 days) inhibits the proliferation and induces the death of colon cancer cell line Caco-2. After 6 days of treatment, the inhibitory effect on proliferation at concentrations ≥50 μM and the inducing effect on cell death at concentrations ≥150 μM are both statistically significant[1].
Sulindac sulfone (600 μM; duration leading to 50% reduction in colony formation) upregulates the expression of the SSAT gene by 3.94-fold in the colon cancer cell line Caco-2 at its IC50 concentration[1].
Sulindac sulfone (10-600 μM; 24-48 h) induces the expression of SSAT mRNA in the colon cancer cell line Caco-2; at the concentration of 600 μM, the expression level increases by 2.23-fold after 24 h of treatment and by 5.58-fold after 48 h of treatment; statistically significant induction is also observed at concentrations ≥100 μM with 48 h of treatment[1].
Sulindac sulfone (600 μM; 48 h) increases SSAT enzyme activity by 2-fold and reduces intracellular spermine and spermidine levels by 2-fold in human colon cancer Caco-2 cells[1].
Sulindac sulfone (600 μM; 48 h) activates PPAR response elements and increases luciferase activity by 2-fold in Caco-2 colon cancer cells after 48 h of treatment[1].
Sulindac sulfone (up to 10 mM) does not inhibit cyclooxygenase (type I) activity[2].
Sulindac sulfone (1-100 μM) weakly inhibits 5-lipoxygenase activity, with inhibition rates of 10%, 14% and 30% at concentrations of 1 μM, 10 μM and 100 μM, respectively[2].
Sulindac sulfone (1-100 μM) exerts no significant inhibitory effect on 15-lipoxygenase activity: the inhibition rate is 8% at 1 μM, 0% at 10 μM, while the enzyme activity increases by 15% instead at 100 μM[2].
Sulindac sulfone (9.4-600 μM; 72 h) inhibits the growth of colon cancer HT-29, DLD-1 and SW480 cells in a dose-dependent manner. A significant reduction in cell viability is observed at concentrations ≥37.5 μM after 72 h of treatment[3].

In Vivo

Sulindac sulfone (500-2000 ppm; dietary; continuous; 31 weeks) inhibits azoxymethane-induced colon carcinogenesis in male F344 rats in vivo in a dose-dependent manner, with the 2000 ppm dose reducing overall colon neoplasia incidence to 26.7% and total tumor multiplicity to 0.43 tumors/animal, without significantly reducing colonic PGE2 levels[2].

Lowered tumor burden to 1.50 cm for adenomas, 1.77 cm for carcinomas, and 3.27 cm for total neoplasia at 1000 ppm (all P < 0.05 vs control).
Reduced colon adenoma incidence to 20.0%, carcinoma incidence to 10.0%, and overall neoplasia incidence to 26.7% at 2000 ppm (all P < 0.05 vs control).
Lowered tumor multiplicity to 0.30 adenomas/animal, 0.13 carcinomas/animal, and 0.43 total neoplasia/animal at 2000 ppm (all P < 0.05 vs control).
Reduced tumor burden to 0.70 cm for adenomas, 1.17 cm for carcinomas, and 1.87 cm for total neoplasia at 2000 ppm (all P < 0.05 vs control).
Exhibited a highly significant dose-response relationship for colon tumor incidence (P < 0.0001), multiplicity (P < 0.0001), and burden (P = 0.0001).
Maintained colonic PGE2 levels at 78-118% of control levels across all doses, with no statistically significant reduction detected in either proximal or distal colon.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
