Possible Interaction: Methotrexate and Thiamine Pyrophosphate

Research Papers that Mention the Interaction

Both the ability of the liposomes to circumvent the transport defect, and the inability of …-glyceroPE to do so, were anticipated on the basis of previous experiments which show that thiamine pyrophosphate could antagonize inhibition of mouse … L1210 cell proliferation by methotrexate and MTX-gamma-glyceroPE, … inhibition by liposomes.

The cytotoxicity of MTX-Cys-SS-αMM46 was not affected by thiamine pyrophosphate , an inhibitor of the active transport of MTX across the cell membrane, but was decreased significantly by ammonium chloride, a lysosomotropic amine.

However, MTX-DMPE I sensitized liposomes apparently enter target cells as a consequence of phagocytosis, and not via the ubiquitous methotrexate … use of thiamine pyrophosphate showed that this compound had no influence on inhibition of cell proliferation due to liposomes, whereas thiamine pyrophosphate … methotrexate and MTX-glyceroPE … these liposomes.
