myo-Inositol trispyrophosphate (ITPP) hexasodium, a modifier of haemoglobin, is an allosteric effector that reduces the oxygen‐binding affinity of haemoglobin and facilitates the release of oxygen by red blood cells. myo-Inositol trispyrophosphate can reverse hypoxia, control tumor growth and improve chemotherapy response.

体外研究(In Vitro)
myo-Inositol trispyrophosphate hexasodium (10 mmol/L; 2 hours) significantly inhibits OCR in all six cell lines (FSaII, SiHa, MDA‐MB‐231, NT2, 9L‐glioma and rhabdomyosarcoma) . has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
myo-Inositol trispyrophosphate hexasodium (2 g/kg weekly; IP; 7weeks) sustains its significant effect on life prolongation.
myo-Inositol trispyrophosphate hexasodium (1.5 g/kg weekly; IV; for 8 weeks) remains metastasis-free on pancreatic carcinomas in immunocompetent male Lewis rats weighing 120-150 g with DSL-6A/C1 cells. myo-Inositol trispyrophosphate hexasodium restores the pO2 pressure in tumors reducing hypoxia-inducible and proangiogenic factors.
myo-Inositol trispyrophosphate hexasodium (2 g/kg; once daily for 2 days) shows the most elevated tumour oxygenation at 2 hours in four mouse tumour models (mouse fibrosarcoma FSaII implanted in C3H mice, mouse mammary tumour NT2 in FVb/Nrj mice, human breast cancer MDA‐MB‐231 in NMRI nude mice and human cervix squamous cell carcinoma SiHa in NMRI nude mice) and two rat tumour models (rat 9L‐glioma in Fischer F344 rat
