Combination Pair ID: 536
Pair Name Vitamin C, GW841819X
Phytochemical Name Vitamin C
Anticancer drug Name GW841819X
Disease Info [ICD-11: 2C30] Melanoma Investigative
Regulate Info Down-regulation Histamine H4 receptor Expression
Result This study shows that ascorbate can enhance the efficacy of BET inhibitors, providing a possible clinical solution to challenges arising in phase I trials from the dose-dependent side effects of this class of epigenetic therapy.

Combination Pair ID: 5
Pair Name Homoharringtonine, Suberoylanilide hydroxamic acid (SAHA)
Phytochemical Homoharringtonine
Drug Suberoylanilide hydroxamic acid (SAHA)
Disease Info [ICD-11: 2A60.Z] Acute myeloid leukemia Investigative
Regulate Info Up-regulation Histamine H4 receptor Acetylation
Result The synergistic effect between HHT and SAHA was blocked partially using a specific anti‑TRAIL antibody. The combination therapy was also found to significantly inhibit the growth of leukemia xenografts in vivo with enhanced apoptosis. These results indicate that, by regulating the induction of TRAIL and activation of the TRAIL apoptotic pathway, it is possible to administer HHT at low concentrations in combination with SAHA as an effective therapeutic approach for the treatment of AML.
Combination Pair ID: 549
Pair Name Sulforaphane, Everolimus
Phytochemical Sulforaphane
Drug Everolimus
Disease Info [ICD-11: 2C94] Bladder cancer Investigative
Regulate Info Up-regulation Histamine H4 receptor Expression
Result The addition of SFN to the long-term everolimus application inhibits resistance development in bladder cancer cells in vitro. Therefore, sulforaphane may hold potential for treating bladder carcinoma in patients with resistance to an mTOR inhibitor.
