Phenotypic drug discovery (PDD) is increasingly being recognized as a viable compliment to target-based drug discovery (TDD). By measuring functional changes, typically at a systems level, PDD can facilitate the identification of compounds having a desirable pharmacology. This capability is particularly important when studying CNS diseases where drug efficacy may require modulation of multiple targets in order to overcome a robust, adaptive biological system. Here, we report the application of a mouse-based high-dimensional behavioral assay to the discovery and optimization of a structurally and mechanistically novel antipsychotic. Lead optimization focused on optimizing complex behavioral features and no explicit effort was made to identify the target (or targets) involved.
A METHOD FOR THE SITE-SPECIFIC ENZYMATIC LABELLING OF NUCLEIC ACIDS IN VITRO BY INCORPORATION OF UNNATURAL NUCLEOTIDES

Paragraph 00176, (2015/02/25)
Provided herein are analogs of unnatural nucleotides bearing predominantly hydrophobic nucleobase analogs that form unnatural base pairs during DNA polymerase- mediated replication of DNA or RNA polymerase-mediated transcription of RNA. In this manner, the unnatural nucleobases can be introduced in a site-specific way into oligonucleotides (single or double stranded DNA or RNA), where they can provide for site-specific cleavage, or can provide a reactive linker than can undergo functionalization with a cargo -bearing reagent by means of reaction with a primary amino group or by means of click chemistry with an alkyne group of the unnatural nucleobase linker.

We synthesized a panel of unnatural base pairs whose pairing depends on hydrophobic and packing forces and identify dTPT3-dNaM, which is PCR amplified with a natural base pair-like efficiency and fidelity. In addition, the dTPT3 scaffold is uniquely tolerant of attaching a propargyl amine linker, resulting in the dTPT3PA-dNaM pair, which is amplified only slightly less well. The identification of dTPT3 represents significant progress toward developing an unnatural base pair for the in vivo expansion of an organism's genetic alphabet and for a variety of in vitro biotechnology applications where it is used to site-specifically label amplified DNA, and it also demonstrates for the first time that hydrophobic and packing forces are sufficient to mediate natural-like replication.

A series of ninety-seven diarylpentanoid derivatives were synthesized and evaluated for their anti-inflammatory activity through NO suppression assay using interferone gamma (IFN-γ)/lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. Twelve compounds (9, 25, 28, 43, 63, 64, 81, 83, 84, 86, 88 and 97) exhibited greater or similar NO inhibitory activity in comparison with curcumin (14.7 ± 0.2 μM), notably compounds 88 and 97, which demonstrated the most significant NO suppression activity with IC50 values of 4.9 ± 0.3 μM and 9.6 ± 0.5 μM, respectively. A structure-activity relationship (SAR) study revealed that the presence of a hydroxyl group in both aromatic rings is critical for bioactivity of these molecules. With the exception of the polyphenolic derivatives, low electron density in ring-A and high electron density in ring-B are important for enhancing NO inhibition. Meanwhile, pharmacophore mapping showed that hydroxyl substituents at both meta- and para-positions of ring-B could be the marker for highly active diarylpentanoid derivatives.

We have prepared a series of piperazinylpyridine derivatives for the treatment of irritable bowel syndrome (IBS). These compounds, which were designed by pharmacophore analysis, bind to both serotonin subtype 1A (5-HT 1A) and subtype 3 (5-HT3) receptors. The nitrogen atom of the isoquinoline, a methoxy group and piper-azine were essential to the pharmacophore for binding to these receptors. We also synthesized furo- and thienopyridine derivatives according to structure-activity relationship analyses. Compound 17c (TZB-20810) had high affinities to these receptors and exhibited 5-HT1A agonistic activity and 5-HT3 antagonistic activity concurrently, and is a promising drug for further development in the treatment of IBS.
