Description

RHPS4 is a potent telomerase inhibitor (IC50 = 0.33 μM). RHPS4 is a DNA damage inducer[1][2].

IC50 & Target

IC50: 0.33 μM (telomerase in the TRAP assay)[1].

In Vitro

RHPS4 could sensitize tumor cells to anticancer agents that act via disparate mechanisms[1].
RHPS4 (0.5-1 μM, 15 days) induces a senescent-like growth arrest in MCF-7 cells[1].
RHPS4 (1 μM, 4 days) induces phosphorylation of H2AX in transformed and tumor cells[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[1]

Cell Line: MCF-7, MCF-7 vector control, and MCF-7 c81 cells.
Concentration: 0, 0.2, 0.5, or 1 μM.
Incubation Time: 7 days.
Result: Inhibited cell proliferation.
In Vivo

RHPS4 (15 mg/kg, iv, 15 days) treatment produces a marked inhibition of tumor weight (tumor weight inhibition [TWI] about 80%; P < 0.001) in a very short time, and this effect persists for at least 30 days. A complete tumor response is observed in 80% of mice, and 40% are cured[2].
In all the other tumor xenografts, RHPS4 treatment produces about 50% (P < 0.001) TWI at the nadir of the effect and, more important, results in a delay of tumor growth of about 15 (M14 and PC3) and 10 (HT29 and H460) days[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: CD-1 male nude (nu/nu) mice, 6–8 weeks old and weighing 22-24 g (H460, CG5 and HT29, PC3 and M14 cancer models)[2].
Dosage: 15 mg/kg.
Administration: IV, daily for 15 consecutive days.
Result: Active as a single agent on all the tumors analyzed. CG5 breast xenografts resulted in the most sensitive tumor.

In Vivo:

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  0.5% CMC-Na/0.1% Tween-80 in Saline water

    Solubility: 2 mg/mL (4.36 mM); Clear solution; Need ultrasonic

  • Protocol 2

    Add each solvent one by one:  15% Cremophor EL    85% Saline

    Solubility: 5 mg/mL (10.91 mM); Clear solution; Need ultrasonic

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.
