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 affected by an agent comprising:
generating a small molecule profile of a cellular compartment treated with an agent, and
comparing said small molecule profile to a standard small molecule profile;
thereby, identifying the small molecules affected by said agent in said cellular compartment, wherein said identified small molecules comprise sugars, fatty acids, nucleotides and amino acids, wherein said cellular compartment is obtained from a patient.
2. The method of claim 1 , wherein said agent is a toxin.
3. The method of claim 1 , wherein said agent is a therapeutic agent.
4. The method of claim 3 , wherein said therapeutic agent is a therapeutic agent used for the treatment of a metabolic, immunological, neurological, oncological, viral, or other disorder.
5. The method of claim 1 , wherein said patient is suffering from a metabolic, immunological, neurological, oncological, viral, or other disorder.
6. The method of claim 1 , wherein said cellular compartment is a cell.
7. The method of claim 1 , wherein said cellular compartment is mitochondria.
8. The method of claim 1 , wherein said cellular compartment is a nucleus.
9. The method of claim 1 , wherein said small molecule profiles are obtained using one or more of the following: gas chromatography (GC), HPLC, TLC, electrochemical analysis, mass spectrometry, mass spectroscopy, refractive index spectroscopy (RI), Ultra-Violet spectroscopy (UV), fluorescent analysis, radiochemical analysis, Near-InfraRed spectroscopy (Near-IR), Nuclear Magnetic Resonance spectroscopy (NMR), and Light Scattering analysis (LS).
10. A method for identifying small molecules affected by an agent comprising:
generating a small molecule profile of a subject treated with an agent, and
comparing said small molecule profile to a standard small molecule profile;
thereby, identifying the small molecules affected by said agent, wherein said identified small molecules comprise sugars, fatty acids, nucleotides and amino acids, wherein said subject is a human.
11. The method of claim 10 , wherein said standard small molecule profile is a profile of a sample from said subject prior to administration of the agent.
12. The method of claim 10 , wherein said small molecule profile is obtained from a cell culture.
13. The method of claim 10 , wherein said small molecule profile is obtained from a biological fluid of said subject.
14. The method of claim 13 , wherein said biological fluid is blood, serum, spinal fluid or saliva.
