Ruelas-Alvarez, Glenda Y. published the artcileExploration of the Luminescence Properties of Organic Phosphate Salts of 3-Quinoline- and 5-Isoquinolineboronic Acid, Formula: C9H8BNO2, the publication is European Journal of Inorganic Chemistry (2019), 2019(22), 2707-2724, database is CAplus.

3-Quinoline- and 5-isoquinolineboronic acids (3QBA and 5IQBA) were combined with 1-naphthyl and di-Ph phosphate (1NP and DPP) to give three crystalline mol. salts of 1:1 stoichiometric composition, viz., 3QBA–1NP, 5IQBA–1NP and 3QBA–DPP. The products were characterized by elemental anal., single-crystal x-ray diffraction studies, IR spectroscopy, luminescence spectroscopy and TG-DSC measurements. The anal. of the solid-state structures revealed that the mol. components are linked by strong charge-assisted hydrogen bonds forming heterodimeric synthons of the type B(OH)₂···^–O₂P and N⁺-H···O(P). In addition, the hydrogen phosphate salts derived from 1NP exhibit the homodimeric P(O)OH···O(HO)P synthon. The aggregates formed through the above-mentioned hydrogen bonding motifs are further connected through π···π interactions, which involve mainly the aromatic rings of the quinolinium/isoquinolinium cations. The crystal structure analyses were accomplished by Hirshfeld surface analyses and the associated 2D fingerprint plots, illustrating the similarities and differences of the three salts more concisely. Solid-state photoluminescence spectroscopy of the title compounds showed emission in the blue region with an extraordinary high quantum yield (Φ_f = 98 %) for compound 3QBA–DPP.

Favalli, Nicholas published the artcileLarge screening of DNA-compatible reaction conditions for Suzuki and Sonogashira cross-coupling reactions and for reverse amide bond formation, Formula: C9H8BNO2, the publication is Bioorganic & Medicinal Chemistry (2021), 116206, database is CAplus and MEDLINE.

Progress in DNA-encoded chem. library synthesis and screening crucially relies on the availability of DNA-compatible reactions, which proceed with high yields and excellent purity for a large number of possible building blocks. In the past, exptl. conditions have been presented for the execution of Suzuki and Sonogashira cross-coupling reactions on-DNA. In this article, our aim was to optimize Suzuki and Sonogashira reactions, comparing our results to previously published procedures. We have tested the performance of improved conditions using 606 building blocks (including boronic acids, pinacol boranes and terminal alkynes), achieving >70% conversion for 84% of the tested mols. Moreover, we describe efficient exptl. conditions for the on-DNA synthesis of amide bonds, starting from DNA derivatives carrying a carboxylic acid moiety and 300 primary, secondary and aromatic amines, as amide bonds are frequently found in DNA-encoded chem. libraries thanks to their excellent DNA compatibility.

Zhao, Yujun published the artcileStructure-Based Discovery of 4-(6-Methoxy-2-methyl-4-(quinolin-4-yl)-9H-pyrimido[4,5-b]indol-7-yl)-3,5-dimethylisoxazole (CD161) as a Potent and Orally Bioavailable BET Bromodomain Inhibitor, COA of Formula: C9H8BNO2, the publication is Journal of Medicinal Chemistry (2017), 60(9), 3887-3901, database is CAplus and MEDLINE.

A series of 9H-pyrimido[4,5-b]indole-containing compounds was designed and synthesized to obtain potent and orally bioavailable BET inhibitors. By incorporation of an indole or a quinoline moiety to the 9H-pyrimido[4,5-b]indole core, we identified a series of small mols. showing high binding affinities to BET proteins and low nanomolar potencies in inhibition of cell growth in acute leukemia cell lines. One such compound, 4-(6-methoxy-2-methyl-4-(quinolin-4-yl)-9H-pyrimido[4,5-b]indol-7-yl)-3,5-dimethylisoxazole (I) has excellent microsomal stability and good oral pharmacokinetics in rats and mice. Orally administered, I achieves significant antitumor activity in the MV4;11 leukemia and MDA-MB-231 triple-neg. breast cancer xenograft models in mice. Determination of the cocrystal structure of I with BRD4 BD2 provides a structural basis for its high binding affinity to BET proteins. Testing its binding affinities against other bromodomain-containing proteins shows that I is a highly selective inhibitor of BET proteins. These data show that I is a potent, selective, and orally active BET inhibitor.
