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 a disease state, comprising:
obtaining a small molecule profile from a biological sample from a subject suffering from said disease state; and
comparing the small molecule profile from the subject to a standard small molecule profile, thereby identifying small molecules relevant to said disease state, wherein said small molecule profile is obtained using one or more techniques which detect 50% or more of the small molecules in said sample.
2. The method of claim 1 , wherein said subject is a human.
3. The method of claim 1 , wherein said disease state is an immunological, neurological, metabolic, oncological, viral, cardiovascular disorder or a bacterial infection.
4. The method of claim 1 , wherein said subject's small molecule profile is obtained from said subject's tissue or biological fluids.
5. The method of claim 1 , wherein said subject's small molecule profile is obtained from said subject's blood, spinal fluid, serum, cells, cellular organelles, urine, interstitial fluid, or saliva.
6. The method of claim 1 , wherein said small molecule profiles are obtained using one or more of the following: HPLC, TLC, electrochemical analysis, mass spectroscopy, refractive index spectroscopy (RI), Ultra-Violet spectroscopy (UV), fluorescent analysis, radiochemical analysis, Near-InfraRed spectroscopy (Near-IR), Nuclear Magnetic Resonance spectroscopy (NMR), gas chromatography (GC) and Light Scattering analysis (LS).
7. The method of claim 1 , wherein said disease state is a nervous system disorder.
8. The method of claim 7 , wherein said nervous system disorder is a neuropathy, Alzheimer disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, motor neuron disease, traumatic nerve injury, multiple sclerosis, acute disseminated encephalomyelitis, acute necrotizing hemorrhagic leukoencephalitis, dysmyelination disease, mitochondrial disease, migrainous disorder, bacterial infection, fungal infection, stroke, aging, dementia, peripheral nervous system diseases or a mental disorder.
