Hydroxymethylation of Quinolines with Na2S2O8 by a Radical Pathway

Quinolines and isoquinolines were treated with Na2S2O8 in a mixture of methanol and water at 70 C to form hydroxymethylated quinolines and isoquinolines in good to moderate yields, under transition-metal-free conditions. The formed hydroxymethyl group was smoothly converted into aldehyde, ester, amide, bromomethyl, (N,N-diethylamino)methyl, cyano, and tetrazole groups, in good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 4-Bromoisoquinoline, you can also check out more blogs about1532-97-4

Photoredox Cross-Coupling: Ir/Ni Dual Catalysis for the Synthesis of Benzylic Ethers

Single-electron transmetalation has emerged as an enabling paradigm for the cross-coupling of Csp3 hybridized organotrifluoroborates. Cross-coupling of alpha-alkoxymethyltrifluoroborates with aryl and heteroaryl bromides has been demonstrated by employing dual catalysis with a combination of an iridium photoredox catalyst and a Ni cross-coupling catalyst. The resulting method enables the alkoxymethylation of diverse (hetero)arenes under mild, room-temperature conditions. (Chemical Equation Presented).

Enantioselective Dearomative Arylation of Isoquinolines

The C1-substituted tetrahydroisoquinolines and 1,2-dihydroisoquinoline constitute an important group and are interesting structural motifs found in many natural products and pharmaceuticals. In this context, a phosphoric-acid-catalyzed enantioselective dearomative arylation of isoquinolines was realized, providing the chiral dihydroisoquinolines with indole substituents at the C1-position in good results (up to >99% yield and 97% ee).

Utilization of an Active Site Mutant Receptor for the Identification of Potent and Selective Atypical 5-HT2C Receptor Agonists

Agonism of the 5-HT2C receptor represents one of the most well-studied and clinically proven mechanisms for pharmacological weight reduction. Selectivity over the closely related 5-HT2A and 5-HT2B receptors is critical as their activation has been shown to lead to undesirable side effects and major safety concerns. In this communication, we report the development of a new screening paradigm that utilizes an active site mutant D134A (D3.32) 5-HT2C receptor to identify atypical agonist structures. We additionally report the discovery and optimization of a novel class of nonbasic heterocyclic amide agonists of 5-HT2C. SAR investigations around the screening hits provided a diverse set of potent agonists at 5-HT2C with high selectivity over the related 5-HT2A and 5-HT2B receptor subtypes. Further optimization through replacement of the amide with a variety of five- and six-membered heterocycles led to the identification of 6-(1-ethyl-3-(quinolin-8-yl)-1H-pyrazol-5-yl)pyridazin-3-amine (69). Oral administration of 69 to rats reduced food intake in an ad libitum feeding model, which could be completely reversed by a selective 5-HT2C antagonist.

Novel pyridyl substituted 4,5-dihydro-[1,2,4]triazolo[4,3-a ]quinolines as potent and selective aldosterone synthase inhibitors with improved in vitro metabolic stability

CYP11B2 inhibition is a promising treatment for diseases caused by excessive aldosterone. To improve the metabolic stability in human liver miscrosomes of previously reported CYP11B2 inhibitors, modifications were performed via a combination of ligand-and structure-based drug design approaches, leading to pyridyl 4,5-dihydro-[1,2,4]triazolo[4,3-a]quinolones. Compound 26 not only exhibited a much longer half-life (t1/2 120 min), but also sustained inhibitory potency (IC50 = 4.2 nM) and selectivity over CYP11B1 (SF = 422), CYP17, CYP19, and a panel of hepatic CYP enzymes.

Structural, kinetic, and docking studies of artificial imine reductases based on biotin-streptavidin technology: An induced lock-and-key hypothesis

An artificial imine reductase results upon incorporation of a biotinylated Cp Ir moiety (Cp = C5Me5-) within homotetrameric streptavidin (Sav) (referred to as CpIr(Biot-p-L)Cl] ? Sav). Mutation of S112 reveals a marked effect of the Ir/streptavidin ratio on both the saturation kinetics as well as the enantioselectivity for the production of salsolidine. For [CpIr(Biot-p-L)Cl] ? S112A Sav, both the reaction rate and the selectivity (up to 96% ee (R)-salsolidine, kcat 14-4 min-1 vs [Ir], KM 65-370 mM) decrease upon fully saturating all biotin binding sites (the ee varying between 96% ee and 45% ee R). In contrast, for [CpIr(Biot-p-L)Cl] ? S112K Sav, both the rate and the selectivity remain nearly constant upon varying the Ir/streptavidin ratio [up to 78% ee (S)-salsolidine, kcat 2.6 min-1, KM 95 mM]. X-ray analysis complemented with docking studies highlight a marked preference of the S112A and S112K Sav mutants for the SIr and RIr enantiomeric forms of the cofactor, respectively. Combining both docking and saturation kinetic studies led to the formulation of an enantioselection mechanism relying on an “induced lock-and-key” hypothesis: the host protein dictates the configuration of the biotinylated Ir-cofactor which, in turn, by and large determines the enantioselectivity of the imine reductase.
