Borovska, Jirina published the artcileAccess of inhibitory neurosteroids to the NMDA receptor, Category: chlorides-buliding-blocks, the publication is British Journal of Pharmacology (2012), 166(3), 1069-1083, database is CAplus and MEDLINE.

Background and Purpose: NMDA receptors are glutamatergic ionotropic receptors involved in excitatory neurotransmission, synaptic plasticity and excitotoxic cell death. Many allosteric modulators can influence the activity of these receptors pos. or neg., with behavioral consequences. 20-Oxo-5β-pregnan-3α-yl sulfate (pregnanolone sulfate; PA-6) is an endogenous neurosteroid that inhibits NMDA receptors and is neuroprotective. The authors tested the hypothesis that the interaction of PA-6 with the plasma membrane is critical for its inhibitory effect at NMDA receptors. Exptl. Approach: Electrophysiol. recordings and live microscopy were performed on heterologous HEK293 cells expressing GluN1/GluN2B receptors and cultured rat hippocampal neurons. Key Results: The authors’ experiments showed that the kinetics of the steroid inhibition were slow and not typical of drug-receptor interaction in an aqueous solution In addition, the recovery from steroid inhibition was accelerated by β- and γ-cyclodextrin. Values of IC₅₀ assessed for novel synthetic C3 analogs of PA-6 differed by more than 30-fold and were pos. correlated with the lipophilicity of the PA-6 analogs. Finally, the onset of inhibition induced by C3 analogs of PA-6 ranged from use-dependent to use-independent. The onset and offset of cell staining by fluorescent analogs of PA-6 were slower than those of steroid-induced inhibition of current responses mediated by NMDA receptors. Conclusion and Implications: The authors conclude that steroid accumulation in the plasma membrane is the route by which it accesses a binding site on the NMDA receptor. Thus, the authors’ results provide a possible structural framework for pharmacol. targeting the transmembrane domains of the receptor.

Seibold, Uwe published the artcileRational Design, Development, and Stability Assessment of a Macrocyclic Four-Hydroxamate-Bearing Bifunctional Chelating Agent for ⁸⁹Zr, Product Details of C19H14Cl2, the publication is ChemMedChem (2017), 12(18), 1555-1571, database is CAplus and MEDLINE.

Zirconium-89 is a positron-emitting radionuclide of high interest for medical imaging applications with positron emission tomog. (PET). For the introduction of this radiometal into biol. active targeting vectors, the chelating agent desferrioxamine B (DFO) is commonly applied. However, DFO is known to form ⁸⁹Zr complexes of limited in vivo stability. Herein we describe the rational design and chem. development of a new macrocyclic four-hydroxamate-bearing chelating agent-1,10,19,28-tetrahydroxy-1,5,10,14,19,23,28,32-octaazacyclohexatriacontan-2,6,11,15,20,24,29,33-octaone (CTH36)-for the stable complexation of Zr⁴⁺. For this purpose, we first performed computational studies to determine the optimal chelator geometry before we developed different synthesis pathways toward the target structures. The best results were obtained using an efficient solution-phase-based synthesis strategy toward the target chelating agent. To enable efficient and chemoselective conjugation to biomols., a tetrazine-modified variant of CTH36 was also developed. The excellent conjugation characteristics of the so-functionalized chelator were demonstrated on the example of the model peptide TCO-c(RGDfK). We determined the optimal ⁸⁹Zr radiolabeling parameters for CTH36 as well as its bioconjugate, and found that ⁸⁹Zr radiolabeling proceeds efficiently under very mild reaction conditions. Finally, we performed comparative complex stability tests for ⁸⁹Zr-CHT36-c(RGDfK) and ⁸⁹Zr-DFO-c(RGDfK), showing improved complex stability for the newly developed chelator CTH36.

A mild, fast, and convenient catalytic system for the coupling of aryl chlorides RCl (R = Ph, pyridin-3-yl, benzodioxol-5-yl, etc.) with primary, secondary, as well as previously challenging tertiary alkyl thiols R¹SH (R¹ = heptyl, cyclohexyl, adamantan-1-yl, etc.) uses an air-stable nickel(II) precatalyst in combination with the low-cost base potassium acetate at room temperature The catalytic system tolerates a variety of functional groups and enables the generation of thioethers for a wide range of substrates, including pharmaceutical compounds RSR¹ in excellent yields. Chemoselective functionalization of disubstituted substrates was demonstrated. Kinetic and NMR studies, as well as DFT computations support a Ni(0)/Ni(II) catalytic cycle and identify the oxidative addition product as the resting state. Acetate coordination and subsequent acetate facilitated the formation of a thiolate complex via internal deprotonation and play a key role in the catalytic cycle.

Hayakawa, Ichiro published the artcileStructure-activity relationship study of gatastatin based on the topliss tree approach, Application In Synthesis of 620-20-2, the publication is Heterocycles (2019), 99(1), 238-247, database is CAplus.

Various analogs of gatastatin I [Ar = 3-ClC₆H₄, 4-MeC₆H₄, 4-^tButC₆H₄, etc.], a γ-tubulin-specific inhibitor, were designed and synthesized by systematically optimizing the aromatic ring at the O⁷-benzyl group in accordance with an operational Topliss tree, and their biol. activities were evaluated. Some derivatives showed stronger cytotoxicity against HeLa cells than gatastatin. Especially, the cytotoxicity of the I [Ar = 3-ClC₆H₄] derivative was about 18-fold stronger than that of gatastatin. However, these derivatives did not exhibit binding ability to the yeast γ-tubulin small complex or inhibitory activity against α,β-tubulin polymerization These results suggested that γ-tubulin strongly recognized the unsubstituted Ph ring of the O⁷-benzyl group in gatastatin.

Huang, Xiaohua published the artcileDiscovery and Hit-to-Lead Optimization of Non-ATP Competitive MK2 (MAPKAPK2) Inhibitors, Formula: C7H8BClO2, the publication is ACS Medicinal Chemistry Letters (2011), 2(8), 632-637, database is CAplus and MEDLINE.

A novel series of non-ATP-competitive MK2 inhibitors based on a furan-2-carboxyamide scaffold was discovered through high-throughput screening using the affinity selection-mass spectrometry-based Automated Ligand Identification System platform. Medicinal chem. efforts optimized the initial screening hit to lead-like compounds with significant improvements in biochem. and cellular potencies, while maintaining excellent kinase selectivity and in vitro pharmacokinetic properties. Biophys. and biochem. studies confirmed the unique non-ATP-competitive binding mode of this series and suggested that highly selective inhibitors of MK2 should be feasible by targeting the outside ATP pocket.

The competitive addition of MeSiHCl₂ to 1-hexene and acetone (initiated by γ-irradiation) has been studied. The relative rate constant depends on acetone concentration and does not obey the Arrhenius equation. A possible explanation is the complexation of methyldichlorosilyl radicals with acetone mols.
