or a pharmaceutically acceptable salt or solvate thereof, to a patient in need thereof, wherein the one or more mTOR pathway related diseases is selected from neurodegenerative diseases, age-related diseases, diseases related to transplant rejection, chronic inflammatory diseases, diseases related to glycogen storage, systemic lupus, diseases related to inflammation and immune activation, anaemia, leucopenia, thrombocytopenia, diseases related to stent coatings, renal insufficiency, obesity, diabetes/insulin resistance, diseases related to non-alcoholic fatty liver, polycystic kidney, and fibrosis and wherein

i) R 1 is alkyl, —CF 3 or —CN, R 4 is selected from H, alkyl, halogen, alkoxy, —CF 3 , —OCF 3 , —SO 2 —CF 3 , —SO—CF 3 or —S—CF 3 and R 5 is independently selected from H, alkyl, halogen, —CF 3 or —CN; or

ii) R 1 is selected from H or halogen, R 4 is H, halogen, —S—CF 3 , —SOCF 3 or —SO 2 CF 3 , and R 5 is independently selected from H, halogen, or —CN; and

R 2 and R 3 are each independently selected from H, alkyl, halogen, —CF 3 or —CN;

R 6 is independently selected from H, alkyl, halogen, alkoxy, —CF 3 , —OCF 3 , —SO 2 CF 3 , —SOCF 3 or —SCF 3 ;

X is heteroatom, N(alkyl) or NH; and

n is 1 to 20.

2. The method of claim 1 , wherein,

or a pharmaceutically acceptable salt, solvate or prodrug thereof.

10. The method of claim 1 , wherein the mTOR pathway related disease is chronic inflammatory disease.

11. The method according to claim 10 , wherein the chronic inflammatory disease is rheumatoid arthritis or organ rejection after transplant.

12. The method of claim 1 , wherein the mTOR pathway related disease is fibrosis.

13. The method according to claim 12 , wherein the fibrosis is fibrosis of the liver, cardiac fibrosis or pulmonary fibrosis.

14. The method of claim 1 , wherein the mTOR pathway related disease is neurodegenerative disease.

15. The method according to claim 14 , wherein the neurodegenerative disease is Alzheimer's disease, Huntington's disease or Parkinson's disease.

16. The method according to claim 14 , wherein the neurodegenerative disease is Parkinson's disease.

17. The method according to claim 14 , wherein the neurodegenerative disease is Huntington's disease.

18. The method according to claim 14 , wherein the neurodegenerative disease is Alzheimer's disease.

19. The method of claim 1 wherein the therapeutically effective amount of a compound of formula (I) is administered in a pharmaceutical composition comprising at least one pharmaceutically acceptable carrier.
