Methods and compositions for treating autophagy related disease states and conditions utilizing AMPK activation
The present invention is directed to the discovery that AMPK activation through Galectin 9 induces autophagy and affects other related processes in response to lyosomal damage which occurs and the use of that mechanism in the treatment of autophagy disease states and/or conditions. The use of modulators of AMPK and optionally a modulator of Galectin 9, TAK1 and/or a lysosomotropic agent for the treatment of autophagy-mediated disease states and/or conditions is described as are pharmaceutical compositions.
1. A method of treating a tuberculosis infection in a subject in need comprising administering to said subject a combination of an effective amount of metformin or its pharmaceutically acceptable salt and at least one lysosomotropic agent selected from the group consisting of O-methyl-serinedodecyl amide (MSDA), (2-(1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydro-1,8-naphthyridin-3-yl)-1H-benzo[d]imidazole-6-carbonitril (LZ-106), siramesine, sphingosine, N-dodecylimidazole, L-leucyl-L-leucine methyl ester (LLOMe) or a pharmaceutically acceptable salt thereof.
2. The method according to claim 1 wherein said lysosomotropic agent is MSDA, LLOMe or a pharmaceutically acceptable salt or mixture there.
3. The method according to claim 1 wherein said lysosomotropic agent is MSDA or a pharmaceutically acceptable salt thereof.
