Drug Fluorouracil
Disease Info [ICD-11: 2B90] Colon cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression
Result The combined effects of HHC with 5-FU exhibit a synergistic inhibition by decreasing ACF formation mediated by down-regulation of COX-2 expression.
Combination Pair ID: 502
Pair Name Hexahydrocurcumin, Fluorouracil
Phytochemical Hexahydrocurcumin
Drug Fluorouracil
Disease Info [ICD-11: 2B90] Colon cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression

Combination Pair ID: 311
Pair Name Juglone, Indomethacin
Phytochemical Juglone
Drug Indomethacin
Disease Info [ICD-11: 2B90] Colon cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression
Result A combination of both was shown to be more effective, suggesting that juglone may be considered for therapeutic intervention of colon cancer.
Combination Pair ID: 175
Pair Name Parthenolide, Balsalazide
Phytochemical Parthenolide
Drug Balsalazide
Disease Info [ICD-11: 2B90] Colon cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression
Result These results demonstrate that parthenolide potentiates the efficacy of balsalazide through synergistic inhibition of NF-κB activation and the combination of dual agents prevents colon carcinogenesis from chronic inflammation.
Combination Pair ID: 480
Pair Name Tectochrysin, Cetuximab
Phytochemical Tectochrysin
Drug Cetuximab
Disease Info [ICD-11: 2B90] Colon cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression
Result Our results indicate that combined therapy with lower concentration of cetuximab and tectochrysin could significantly enhance the cancer cell growth inhibitory effect through the inhibition of EGFR signaling.
Combination Pair ID: 478
Pair Name Tetrahydrocurcumin, Celecoxib
Phytochemical Tetrahydrocurcumin
Drug Celecoxib
Disease Info [ICD-11: 2C77] Cervical cancer Investigative
Regulate Info Down-regulation Prostaglandin G/H synthase 2 Expression
Result The combinational treatment effect of THC and celecoxib causing inhibition of tumor growth and tumor angiogenesis via down-regulation of VEGF, COX-2 and EGFR expression. However, this combined treatment did not show the synergistic effect on inhibiting the tumor growth and tumor angiogenesis in cervical cancer (CaSki)-implanted nude mice model.
