Mahmoodi, Niusha;Harijan, Rajesh K.;Schramm, Vern L. research published 《 Transition-State Analogues of Phenylethanolamine N-Methyltransferase》, the research content is summarized as follows. Phenylethanolamine N-methyltransferase (PNMT) is a critical enzyme in catecholamine synthesis. It transfers the Me group of S-adenosylmethionine (SAM) to catalyze the synthesis of epinephrine from norepinephrine. Epinephrine has been associated with diverse human processes, including the regulation of blood pressure and respiration, as well as neurodegeneration found in Alzheimer’s disease. Human PNMT (hPNMT) proceeds through an S_N2 transition state (TS) in which the transfer of the Me group is rate limiting. TS analog enzyme inhibitors are specific for their target and bind orders of magnitude more tightly than their substrates. Mols. resembling the TS of hPNMT were designed, synthesized, and kinetically characterized. This new inhibitory scaffold was designed to mimic the geometry and electronic properties of the hPNMT TS. Synthetic efforts resulted in a tight-binding inhibitor I with a K_i value of 12.0 nM. This is among the first of the TS analog inhibitors of methyltransferase enzymes to show an affinity in the nanomolar range. Isothermal titration calorimetry (ITC) measurements indicated neg. cooperative binding of inhibitor to the dimeric protein, driven by favorable entropic contributions. Structural anal. revealed that I binds to hPNMT by filling the catalytic binding pockets for the cofactor (SAM) and the substrate (norepinephrine) binding sites.

Kevin;Houk, Kendall N.;Glorius, Frank research published 《 Photochemical intermolecular dearomative cycloaddition of bicyclic azaarenes with alkenes》, the research content is summarized as follows. Dearomative cycloaddition reactions represent an ideal means of converting flat arenes into three-dimensional architectures of increasing interest in medicinal chem. Quinolines, isoquinolines, and quinazolines, despite containing latent diene and alkene subunits, are scarcely applied in cycloaddition reactions because of the inherent low reactivity of aromatic systems and selectivity challenges. Here, we disclose an energy transfer-mediated, highly regio- and diastereoselective intermol. [4 + 2] dearomative cycloaddition reaction of these bicyclic azaarenes with a plethora of electronically diverse alkenes. This approach bypasses the general reactivity and selectivity issues, thereby providing various bridged polycycles that previously have been inaccessible or required elaborate synthetic efforts. Computational studies with d. functional theory elucidate the mechanism and origins of the observed regio- and diastereoselectivities.

Li, Haoxi;Mirabel, Rosa;Zimmerman, Joseph;Ghiviriga, Ion;Phidd, Darian K.;Horenstein, Nicole;Urs, Nikhil M. research published 《 Structure-Functional Selectivity Relationship Studies on A-86929 Analogs and Small Aryl Fragments toward the Discovery of Biased Dopamine D1 Receptor Agonists》, the research content is summarized as follows. Dopamine regulates normal functions such as movement, reinforcement learning, and cognition, and its dysfunction has been implicated in multiple psychiatric and neurol. disorders. Dopamine acts through D1- (D1R and D5R) and D2-class (D2R, D3R, and D4R) receptors and activates both G protein- and β-arrestin-dependent signaling pathways. Current dopamine receptor-based therapies are used to ameliorate motor deficits in Parkinson’s disease or as antipsychotic medications for schizophrenia. These drugs show efficacy for ameliorating only some symptoms caused by dopamine dysfunction and are plagued by debilitating side effects. Studies in primates and rodents have shown that shifting the balance of dopamine receptor signaling toward the arrestin pathway can be beneficial for inducing normal movement, while reducing motor side effects such as dyskinesias, and can be efficacious at enhancing cognitive function compared to balanced agonists. Several structure-activity relationship (SAR) studies have embarked on discovering β-arrestin-biased dopamine agonists, focused on D2 partial agonists, noncatechol D1 agonists, and mixed D1/D2R dopamine receptor agonists. Here, we describe an SAR study to identify novel D1R β-arrestin-biased ligands using A-86929, a high-affinity D1R catechol agonist, as a core scaffold to identify chem. motifs responsible for β-arrestin-biased activity at both D1 and D2Rs. Most of the A-86929 analogs screened were G protein-biased, but none of them were exclusively arrestin-biased. Addnl., various small-fragment mol. probes displayed weak bias toward the β-arrestin pathway. Continued in-depth SFSR (structure-functional selectivity relationship) studies informed by structure determination, mol. modeling, and mutagenesis studies will facilitate the discovery of potent and efficacious arrestin-biased dopamine receptor ligands.
