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.

The present invention provides a method for combining the advantages of encoded molecule fragments made by split and mix synthesis with the advantages of template directed synthesis of molecules. The method provided in the invention comprises the steps of: Adding a linker molecule L to one or more reaction wells; Adding a molecule fragment to each of said reaction wells; Adding an oligonucleotide identifier to each of said reaction wells; Subjecting said wells to conditions sufficient to allow said molecule fragments and said oligonucleotie identifiers to become attached to said linker molecule, or conditions sufficient for said molecule fragments to bind to other molecule fragments and sufficient for said oligonucleotide identifiers to bind to other oligonucleotide identifiers; Combining the contents of said one or more reaction wells; Optionally, distributing the combined product to one or more new reaction wells; Optionally, repeating steps b) to e) one or more times; Contacting the resulting bifunctional molecule(s) of step e) or g) with one or more Contacting the resulting bifunctional molecule(s) of step e) or g) with one or more (oligonucleotide) templates each capable of hybridizing to at least one of the oligonucleotide identifiers added in step c).

A system for screening a small molecule library with 250,000 molecules to find out a compound of an anti-hypertensive drug aiming at human Angiotensin II type IA receptor is provided. The system includes a first database having a three-dimensional structure datum of a human Angiotensin II type IA receptor, a second database having molecular data of a plurality of small molecules, and a computer acquiring the three-dimensional structure datum and the molecular data from the first database and the second database respectively, wherein the computer has a molecular docking software for calculating a free energy of the human Angiotensin II type IA receptor bound to each of the plurality of small molecules, ranks the plurality of small molecules according to the respective free energy so as to select a top small molecule in the ranking as the compound of the drug.

The invention relates to an anti-inflammatory inhibitor screening model taking MyD88TIR (myeloid differentiation primary response protein 88 Toll / interleukin-1 receptor) dimerization as a target point and application thereof. The anti-inflammatory inhibitor screening model taking the MyD88TIR dimerization as the target point is characterized in that: an MyD88TIR builds fusion protein plasmids together with protein genes GFP / RFP (Green fluorescent protein / Red fluorescent protein) of a fluorescence donor and a fluorescent receptor, and the fusion protein plasmids are transfected into mammalian cells to build dual-positive expression cell strains; the FRET (fluorescence resonance energy transfer) phenomenon can be detected; when an MyD88TIR dimerization inhibitor exists in a culture medium, the cell strains which depend on dual-positive to express GFP-MyD88-TIR and RFP-MyD88-TIR are suggested, and whether the inhibitor directly blocks the interaction of the TIRs or not can be further determined according to in vitro binding analysis; and combined with the fluorescent FRET blocking results of eukaryotic cells and prokaryotic expression recombinant protein interaction analysis, the MyD88TIR dimerization inhibitor can be determined. The model can be used for widely screening commercialized small molecule libraries, self-prepared natural product components, or various chemical compounds, and modifiers, from which MyD88 dimerization inhibitory compounds are obtained to participate in the drug screening of MyD88 signal pathway-dependent chronic inflammation and autoimmune diseases.

The invention relates to novel methods of detecting alterations in cell cycle regulation in a cell or a cell population and screening for agents capable of modulating cell cycle regulation through the use of multiparameter assays and a fluorescence-activated cell sorter (FACS) machine.
