Methods for drug discovery, disease treatment, and diagnosis using metabolomics
View Patent ↗The small molecule profiles of cells are compared to identify small molecules which are modulated in altered states. Cellular small molecule libraries, methods of identifying tissue sources, methods for treating genetic and non-genetic diseases, and methods for predicting the efficacy of drugs are also discussed.
1. A method for identifying small molecules relevant to depression, comprising:
generating a small molecule profile from a patient sample, wherein said patient suffers from depression, and
comparing said small molecule profile to a standard small molecule profile obtained from a sample from a healthy individual; thereby identifying the small molecules relevant to depression, wherein said small molecule profile comprises information regarding sugars, fatty acids, amino acids and nucleotides.
2. The method of claim 1 , wherein the method for analyzing said sample is selected from the group consisting of gas chromatography (GC), HPLC, TLC, electrochemical analysis, mass spectrometry, mass spectroscopy, refractive index spectroscopy (RI), Ultraviolet spectroscopy (UV), fluorescent analysis, radiochemical analysis, Near-Infrared spectroscopy (Near-IR), Nuclear Magnetic Resonance spectroscopy (NMR) and Light Scattering analysis (LS).
3. The method of claim 2 , wherein the method for analyzing the sample comprises two or more methods.
4. The method of claim 1 , wherein the subject is a human.
5. The method of claim 1 , wherein said standard sample is derived from one or more healthy subjects.
6. The method of claim 1 , wherein said small molecule profiles are obtained from a body sample selected from the group consisting of said subject's serum, cells, interstitial fluid, saliva, brain, muscle, retinal tissue, nerve tissue, urine, spinal fluid, and blood.
