Kim, Minsoo published the artcileStructure activity relationship exploration of 5-hydroxy-2-(3-phenylpropyl)chromones as a unique 5-HT_2B receptor antagonist scaffold, Computed Properties of 620-20-2, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(21), 127511, database is CAplus and MEDLINE.

Antagonists for the serotonin receptor 2B (5-HT_2B) have clin. applications towards migraine, anxiety, irritable bowl syndrome, and MDMA abuse; however, few selective 5-HT_2B antagonists have been identified. Previous studies from these labs identified a natural product, 5-hydroxy-2-(2-phenylethyl)chromone (5-HPEC, 2) as the first non-nitrogenous ligand for the 5-HT_2B receptor. Studies on 5-HPEC optimization led to the identification of 5-hydroxy-2-(3-phenylpropyl)chromone (5-HPPC, 3), which showed a tenfold improvement in binding affinity over 2 at 5-HT_2B. This study aimed to further improve receptor pharmacol. of this unique scaffold. Guided by mol. modeling studies modifications at the C-3′ and C-4′ positions of 3 were made to probe their effects on ligand binding affinity and efficacy. Among the derivatives synthesized 5-hydroxy-2-(3-(3-cyanophenyl)propyl)chromone (5-HCPC, 3d) showed the most promise with a multifold improvement in binding affinity (pK_i = 7.1 ± 0.07) over 3 with retained antagonism.

Cho, Jian-Yang published the artcileRemarkably selective iridium catalysts for the elaboration of aromatic C-H bonds, Name: Methyl 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate, the publication is Science (Washington, DC, United States) (2002), 295(5553), 305-308, database is CAplus and MEDLINE.

Arylboron compounds have intriguing properties and are important building blocks for chem. synthesis. A family of Ir catalysts (IndIr(COD), (η⁶-mesitylene)Ir(BPin)₃ (4; HBPin = pinacolborane)) now enables the direct synthesis of arylboron compounds from aromatic hydrocarbons and boranes under solventless conditions. For example, a 98% yield of PhBPin was obtained in 15 h at 150° from benzene and HBPin (16:1 ratio) in the presence of 4 and PMe₃. The Ir catalysts are highly selective for C-H activation and do not interfere with subsequent in situ transformations, including Pd-mediated cross-couplings with aryl halides (e.g. 80% 3,5-dichloro-3′-methylbiphenyl). By virtue of their favorable activities and exceptional selectivities, these Ir catalysts impart the synthetic versatility of arylboron reagents to C-H bonds in aromatic and heteroaromatic hydrocarbons.

Shi, Feng published the artcileSelective oxidation of naphthalene derivatives with ruthenium catalysts using hydrogen peroxide as terminal oxidant, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Molecular Catalysis A: Chemical (2007), 270(1-2), 68-75, database is CAplus.

The selective oxidation of naphthalene and its derivatives to give naphthoquinones has been investigated in detail. The reaction can be carried out effectively in the presence of a catalytic amount of Ru complexes (0.2 mol %) and phase transfer catalysts using H₂O₂ as the terminal oxidant and water as the solvent. The effects of different ruthenium complexes, phase transfer catalysts, and the concentration of hydrogen peroxide were studied. Compared to previous procedures for this type of reaction, acidic solvents and high concentration of hydrogen peroxide are not necessary, which makes the reaction more environmentally friendly.

Takale, Balaram S. published the artcileSustainable and Cost-Effective Suzuki-Miyaura Couplings toward the Key Biaryl Subunits of Arylex and Rinskor Active, COA of Formula: C7H7BClFO3, the publication is Organic Letters (2020), 22(12), 4823-4827, database is CAplus and MEDLINE.

Challenging Suzuki-Miyaura cross couplings associated with novel crop protection active ingredients from Corteva Agriscience, Arylex and Rinskor, can be performed in water using ppm (ppm) levels of a Pd catalyst. Each coupling required a distinct set of reaction conditions to achieve maximum selectivities and chem. yields. By way of comparison, this chem. is not only performed under environmentally responsible aqueous micellar conditions, but also involves lowering loadings (3-5 times) of endangered palladium than used previously to attain a more sustainable process.

Lipophilic chalcones and their conformationally restricted analogs were synthesized and evaluated for their antitubercular efficacy against Mycobacterium tuberculosis H37Rv strain. Compounds I, II, and III [R = CH₂CH₂-(piperidin-1-yl), CH₂CHMeCH₂NMe₂] were found to be active MIC at 60, 30, 3.5 and 7.5 μg-mL^-1. In vitro cytotoxicity of compounds I, II, III [R = CH₂CH₂-(piperidin-1-yl), CH₂CHMeCH₂NMe₂] and IV in non-cancerous human epithelial kidney cell line (HEK-293) showed that most active compound III [CH₂CH₂-(piperidin-1-yl)] was approx. 2.85 times selective towards tubercular vs. healthy cells whereas II was found to be 16 times selective.

Blake, Steven published the artcileSalicylanilide Analog Minimizes Relapse of Clostridioides difficile Infection in Mice, Product Details of C6H3ClFNO2, the publication is Journal of Medicinal Chemistry (2020), 63(13), 6898-6908, database is CAplus and MEDLINE.

Clostridioides difficile infection (CDI) causes serious and sometimes fatal symptoms like diarrhea and pseudomembranous colitis. Although antibiotics for CDI exist, they are either expensive or cause recurrence of the infection due to their altering the colonic microbiota, which is necessary to suppress the infection. Here, we leverage a class of known membrane-targeting compounds that we previously showed to have broad inhibitory activity across multiple Clostridioides difficile strains while preserving the microbiome to develop an efficacious agent. A new series of salicylanilides was synthesized, and the most potent analog was selected through an in vitro inhibitory assay to evaluate its pharmacokinetic parameters and potency in a CDI mouse model. The results revealed reduced recurrence of CDI and diminished disturbance of the microbiota in mice compared to standard-of-care vancomycin, thus paving the way for novel therapy that can potentially target the cell membrane of C. difficile to minimize relapse in the recovering patient.

Barnash, Kimberly D. published the artcileDiscovery of Peptidomimetic Ligands of EED as Allosteric Inhibitors of PRC2, Computed Properties of 6313-54-8, the publication is ACS Combinatorial Science (2017), 19(3), 161-172, database is CAplus and MEDLINE.

The function of EED within Polycomb repressive complex 2 (PRC2) is mediated by a complex network of protein-protein interactions. Allosteric activation of PRC2 by binding of methylated proteins to EED’s aromatic cage is essential for full catalytic activity, but details of this regulation are not fully understood. EED’s recognition of the product of PRC2 activity, histone H3 lysine 27 trimethylation (H3K27me3), stimulates PRC2 methyltransferase activity at adjacent nucleosomes leading to H3K27me3 propagation and, ultimately, gene repression. By coupling combinatorial chem. and structure-based design, we optimized a low affinity methylated Jarid2 peptide to a smaller, more potent peptidomimetic ligand (Kd = 1.14 ± 0.14 μM) of the aromatic cage of EED. Our strategy illustrates the effectiveness of applying combinatorial chem. to achieve both ligand potency and property optimization. Furthermore, the resulting ligands, UNC5114 and UNC5115, demonstrate that targeted disruption of EED’s reader function can lead to allosteric inhibition of PRC2 catalytic activity.
