生物活性

RRx-001, a hypoxia-selective epigenetic agent and studied as a radio- and chem-sensitizer, triggers apoptosis and overcomes drug resistance in myeloma. RRx-001 exhibits potent anti-tumor activity with minimal toxicity[1]. RRx-001 is a dual small molecule checkpoint inhibitor by downregulating CD47 and SIRP-α[2]. RRx-001 is a potent inhibitor of G6PD and shows potent antimalarial activity[3].

体外研究
(In Vitro)

RRx-001 (0-5 μM, 24 hours) inhibits MM cells growth and overcomes resistance to novel and conventional therapies[1].
RRx-001 blocks migration of MM cells and associated angiogenesis[1].
RRx-001 induces significant G1 phase growth arrest, with concomitant decrease in S phase. RRx-001 triggers significant apoptosis in MM cells[1].
RRx-001 inhibits DNA methylation by downregulating DNA methytransferases[1].
RRx-001 and the supernatant of RRx-001-treated macrophages downregulates CD47 on tumor cells and SIRPα on macrophages[2].

Cell Viability Assay[1]

Cell Line: Human MM-cell lines (MM.1S, RPMI-8226, H929, ARP1, KMS-11, OPM2, LR5, ANBL6.WT), along with drug resistant cell lines such as (MM.1R, Dox40, LR5, ANBL6.BR, RPMI-8226).
Concentration: 0-5 μM.
Incubation Time: 24 hours.
Result: Induced a dose-dependent significant (p < 0.05) decrease in viability of all cell lines.

体内研究
(In Vivo)

RRx-001 (5 mg/kg or 10 mg/kg, I.V., thrice-weekly for 24 days) inhibits tumor growth and prolongs survival in a xenograft mouse model[1].
RRx-001 (10 mg/kg, IP, twice a week and once a day) exhibits potent anti-cancer activity on the A549 lung cancer model dependent on the presence of tumor-associated macrophages (TAMs) in tumor tissue[2].

Animal Model: CB-17 SCID-mice were subcutaneously inoculated with 5.0 × 106 MM.1S cells in 100 µL of serum-free RPMI 1640 medium[1].
Dosage: 5 mg/kg or 10 mg/kg.
Administration: I.V., thrice-weekly for 24 days.
Result: Blocked MM tumor growth and enhances survival.
Treatment was well tolerated, suggested by no apparent weight loss.
Animal Model: Female BALB/c nude mice (19.2 ± 1.7 g) based on A549 lung cancer model[2].
Dosage: 10 mg/kg.
Administration: IP, twice a week and once a day.
Result: Resulted in the most significant tumor growth retardation.
Reduction of resident macrophages in tumor-bearing mice attenuates the antitumor activity of RRx-001.
