Paragraph 0008, (2017/09/02)
The invention relates to a synthesizing method of (E)-5-methyl-1H-pyrrolo-[2,3-b] pyridine-3-formaldoxime, which solves the technical problem that an effective synthesizing method is not discovered at present. The synthesizing method provided by the invention comprises the following steps: brominating 2-amino-5-picoline, so as to obtain a compound 1; performing a reaction on the compound 1 and trimethylsilylacetylene under a condition of a Sonogashira coupling reaction, so as to generate a compound 2; performing a reaction on the compound 2 and sodium hydride to form a pyrrole ring, so as to generate a compound 3; performing a reaction on the compound 3 and urotropine, so as to generate a compound 4; performing the compound 4, hydroxylamine hydrochloride and sodium acetate, so as to obtain the target product (E)-5-methyl-1H-pyrrolo-[2,3-b] pyridine-3-formaldoxime. As a sodium acetate, the (E)-5-methyl-1H-pyrrolo-[2,3-b] pyridine-3-formaldoxime is widely applied in the pharmaceutical industry.
Exploring the isoform selectivity of TGX-221 related pyrido[1,2-a]pyrimidinone-based Class IA PI 3-kinase inhibitors: Synthesis, biological evaluation and molecular modelling

A novel series of TGX-221 analogues was prepared and tested for their potency against the p110α, p110β, and p110δ isoforms of the PI3K enzyme, and in two cellular assays. The biological results were interpreted in terms of a p110β comparative model, in order to account for their selectivity towards this isoform. A CH2NH type linker is proposed to allow binding into the specificity pocket proposed to accommodate the high p110β-selectivity of TGX-221, although there was limited steric tolerance for substituents on the pendant ring with the 2-position most favourable for substitution.
Synthesis and study of nucleic acids interactions of novel monomethine cyanine dyes

scheme or table, p. 1184 - 1191 (2012/03/27)
Six asymmetric monomethine cyanine dyes have been synthesized and their spectral characteristics and interaction with double stranded (ds)DNA have been investigated for their prospective use as fluorescent markers in molecular biology. Therefore, the non-covalent binding of the compounds with dsDNA was explored. Apart from the fluorescence spectroscopy, the study includes UV/Vis spectrophotometry and circular dichroism spectroscopy, as well as the thermal melting experiments. Although the compounds show relatively low binding affinity toward dsDNA and do not have intrinsic fluorescence, in the presence of dsDNA they exhibited considerable enhancement in fluorescence intensity. Therefore the studied dyes show interesting platform for future modifications directed toward more sequence selective derivatives. The compound with the highest affinity toward dsDNA showed interesting anti-proliferative potential and specificity.

experimental part, p. 9063 - 9066 (2011/12/03)
Small heteroaromatic rings are valuable monomers in drug discovery that can enable rapid access to novel and desirable chemical space. Installation of a synthetic handle on a heteroaromatic core may be difficult if steric and electronic factors are not in alignment with the desired transformation. Described are practical routes for the construction of 5-bromo-6-methyl imidazopyrazine (1) as well as 5-bromo and 5-chloro-6-methyl imidazopyridines (2a and 2b), which were developed using electron density surface maps encoded with ionization potential to guide synthetic strategy.

A series of novel 2-pyridinyl-3-(4-methylsulfonyl)phenylpyridines has been synthesized and evaluated with respect to their ability to inhibit the isozymes of cyclooxygenase, COX-1, and COX-2. Optimum COX-2 activity is observed by introduction of a substituent at C5 of the central pyridine. 5- Chloro-3-(4-methylsulfonyl)phenyl-2(2-methyl-5-pyridinyl)pyridine 33 was identified as the optimum compound in this series.
