Mécanisme d'action (Mechanism of Action)

In vitro	Evofosfamide (TH-302) is selectively potent under hypoxia and stable to liver microsomes. Substitution of the chlorine with bromine on the phosphorus mustard in 3b increases the potency by 10-fold and maintaines the high hypoxic selectivity [Hypoxia cytotoxicity ratio (HCR) = 270]. In both human lung cancer H460 cells and human colon cancer HT29 cells, potent cytotoxicity of this compound is observed under N₂. It inhibits H460 cells and HT29 cells with IC90 of 0.1 μM and 0.2 μM, respectively. It shows much enhanced potency in H460 spheroids compared to H460 monolayer cells under normoxia. This compound exhibits potent cytotoxicity to MM cells with hypoxic selectivity and dose dependency. It can induce G0/G1 cell-cycle arrest under hypoxic conditions. The effect of it on cell-cycle machinery is mediated by down-regulating cyclin D1/2/3, CDK4/6, p21cip-1, p27kip-1, and pRb expression, whereas CDK2 expression remained undisturbed. It can induce dose-dependent apoptosis in both human and murine MM cells in hypoxic conditions. TH-302-activated apoptosis is mediated through down-regulating the antiapoptotic proteins BCL-2 and BCL-xL, as well as up-regulating the expression of cleaved proapoptotic protein caspase-3, -8, and -9 and poly ADP-ribose polymerase. In contrast to the hypoxia-specific toxicity, it shows very low toxicity in normoxic condition, even at high concentrations.
In vivo	Evofosfamide (TH-302) inhibits primary tumor growth by 41% on day 25 after implantation, whereas this compound plus a nucleoside analog inhibits primary tumor growth by 96% on day 25. When administered at 6.25, 12.5, 25, or 50 mg/kg in the H460 NSCLC xenograft model QD × 5/wk × 2 wks (once a day for 5 days per week for 2 weeks) i.p., it shows tumor growth inhibition at Day 22 of 43%, 51%, 75%, and 89%, respectively. At 100 mg/kg, it causes a decrease in blood cell counts 3 days after treatment end, but these are totally recovered 7 days post-treatment. Under all tested regimens, it exhibits efficacy metrics ranging from 58% to 89% tumor growth inhibition. Its induced cell killing is breathing oxygen concentration dependent, with the greatest cytotoxicity occurring when the tumor-bearing mice are exposed to low oxygen concentrations. Tumor growth is significantly reduced by this compound in animals breathing 10% O₂ compared with 95% O₂ breathing. After treatment, the pimonidazole-positive area is significantly decreased at 48 hours after dosing (6.3 % in vehicle vs. 1.8 % in the TH-302 treatment group).
