Current pain therapeutics suffer from undesirable psychotropic and sedative side effects, as well as abuse potential. Glycine receptors (GlyRs) are inhibitory ligand-gated ion channels expressed in nerves of the spinal dorsal horn, where their activation is believed to reduce transmission of painful stimuli. Herein, we describe the identification and hit-to-lead optimization of a novel class of tricyclic sulfonamides as allosteric GlyR potentiators. Initial optimization of high-throughput screening (HTS) hit 1 led to the identification of 3, which demonstrated ex vivo potentiation of glycine-activated current in mouse dorsal horn neurons from spinal cord slices. Further improvement of potency and pharmacokinetics produced in vivo proof-of-concept tool molecule 20 (AM-1488), which reversed tactile allodynia in a mouse spared-nerve injury (SNI) model. Additional structural optimization provided highly potent potentiator 32 (AM-3607), which was cocrystallized with human GlyRalpha3cryst to afford the first described potentiator-bound X-ray cocrystal structure within this class of ligand-gated ion channels (LGICs).

An effective method for transition-metal-free postfunctionalization of thiazolo[3,2-c][1,3,5,2]oxadiazaborinine dyes via direct lithiation of the 1,3-thiazole ring was developed. The reaction allows valuable regioselective C-H modification of these N,O-chelated organoboron chromophores incorporating different groups, including C-, Hal-, Si-, S-, Se-, and Sn-substituents. As a result, a library of novel fluorescent 1,3-thiazole-based organoboron complexes has been synthesized and characterized. The influence of the donor/acceptor strength of the substituent E on the photophysical properties has been established. The compound with a bulky lipophilic substituent (SnBu3) exhibits a relatively high solid-state photoluminescence quantum yield of 44%.

Oxazoline and camphor-pyrazole units are introduced on the 1,8-naphthyridine scaffold to access chiral ligands L1, L2 and L3. Metalation of these chiral ligands with Cu(I) and Ag(I) precursors afforded di- and tetranuclear complexes [Cu4I4(L1)2] (1), [Cu4I4(L2)2] (2), [Cu2I2(L3)] (3), [Cu2I(L2)2](OTf) (4), [Ag2(L1)2](OTf)2 (5) and [Ag4(L2)4Br](OTf)3 (6), containing [M4Xn] (n = 1,4 and X = Br, I) or [M2Xn] (n = 0, 1, 2 and X = I) core. All complexes are structurally characterized. Naphthyridine-derived ligands reveal bridge-chelate coordination motif and hold two metal centers in close proximity. The tetranuclear complexes are dimer of dinuclear complexes bridged by the halides. Electronic absorption and emission spectra of copper complexes are reported. Catalytic utility of all complexes are examined for asymmetric transformations but they showed poor activity probably due to limited solubility and coordinative saturation at the metal centers. The best results are obtained with [L3/Cu salt] combination for cyclopropanation of styrene, N?H bond insertion and nitroaldol (Henry) reactions with very low enantioselectivity.

While IFN-based hepatitis C virus (HCV) treatment regimens required long treatment duration, they only achieved a limited cure rate in HCV-infected patients and were accompanied by significant therapy-based side effects. The first curative IFN-sparing therapies revolutionized HCV treatment by utilizing a cocktail of mechanistically orthogonal direct-acting antiviral (DAA) agents to achieve much higher cure rates in a shorter period of time and with fewer side effects. One of the drug targets that these therapies usually engaged was the HCV NS5A protein. This chapter reviews the Abbott/AbbVie HCV NS5A program, which discovered inhibitors of this protein using an in vitro phenotypic screen, validated the mechanism in vivo, and ultimately discovered two FDA-approved NS5A inhibitors ombitasvir (OMB) and pibrentasvir (PIB). OMB, a first-generation NS5A inhibitor, is a component of two FDA-approved IFN-sparing DAA therapies (Viekira Pak and Technivie) with approval to treat genotypes 1 and 4, respectively. PIB, a next-generation NS5A inhibitor included in AbbVie?s next-generation therapy Mavyret (or Maviret), prevents replication of HCV genotypes 1?6 and exhibits an improved resistance profile relative to other FDA-approved first-generation NS5A inhibitors.

Aromatic N-heterocycles have been used in electrochemical CO2 reduction, but their precise role is not yet fully understood. We used first-principles quantum chemistry to determine how the molecular sizes and substituent groups of these molecules affect their standard redox potentials involving various proton and electron transfers. We then use that data to generate molecular Pourbaix diagrams to find the electrochemical conditions at which the aromatic N-heterocycle molecules could participate in multiproton and electron shuttling in accordance with the Sabatier principle. While one-electron standard redox potentials for aromatic N-heterocycles can vary significantly with molecule size and the presence of substituent groups, the two-electron and two-proton standard redox potentials depend much less on structural modifications and substituent groups. This indicates that a wide variety of aromatic N-heterocycles can participate in proton, electron, and/or hydride shuttling under suitable electrochemical conditions.
