The capsid protein (CA) of HIV-1 plays essential roles in multiple steps of the viral replication cycle by assembling into functional capsid core, controlling the kinetics of uncoating and nuclear entry, and interacting with various host factors. Targeting CA represents an attractive yet underexplored antiviral approach. Of all known CA-targeting small molecule chemotypes, the peptidomimetic PF74 is particularly interesting because it binds to the same pocket used by a few important host factors, resulting in highly desirable antiviral phenotypes. However, further development of PF74 entails understanding its pharmacophore and mitigating its poor metabolic stability. We report herein the design, synthesis, and evaluation of a large number of PF74 analogs aiming to provide a comprehensive chemical profiling of PF74 and advance the understanding on its detailed binding mechanism and pharmacophore. The analogs, containing structural variations mainly in the aniline domain and/or the indole domain, were assayed for their effect on stability of CA hexamers, antiviral activity, and cytotoxicity. Selected analogs were also tested for metabolic stability in liver microsomes, alone or in the presence of a CYP3A inhibitor. Collectively, our studies identified important pharmacophore elements and revealed additional binding features of PF74, which could aid in future design of improved ligands to better probe the molecular basis of CA-host factor interactions, design strategies to disrupt them, and ultimately identify viable CA-targeting antiviral leads.

Reusable catalysts based on earth-abundant metals with a broad applicability in organic synthesis are a key to a more sustainable production of fine chemicals, pharmaceuticals and agrochemicals. Herein, we report on a nanostructured nickel catalyst for the general and selective synthesis of primary amines via reductive amination, employing ammonia dissolved in water. Our catalyst, which operates at low temperature and pressure, is highly active, reusable and easy to handle. The synthesis from a specific nickel complex and gamma-Al2O3 is straightforward, with the ligand-metal combination of this complex being crucial. Aldehydes (including purely aliphatic ones), aryl-alkyl, dialkyl and diaryl ketones can all be converted smoothly into primary amines. In addition, the amination of pharmaceuticals, bioactive compounds and natural products is demonstrated. Many functional groups-including hydrogenation-sensitive examples-are tolerated. We expect that our findings will inspire others to develop reusable and nanostructured earth-abundant metal catalysts for complex organic transformations.

Formula: C13H13N. I found the field of Science & Technology – Other Topics very interesting. Saw the article Modular click chemistry libraries for functional screens using a diazotizing reagent published in 2019, Reprint Addresses Sharpless, KB; Dong, JJ (corresponding author), Univ Chinese Acad Sci, Ctr Excellence Mol Synth, Shanghai Inst Organ Chem, Key Lab Organofluorine Chem,Chinese Acad Sci, Shanghai, Peoples R China..

Click chemistry is a concept in which modular synthesis is used to rapidly find new molecules with desirable properties(1). Copper(I)-catalysed azide-alkyne cycloaddition (CuAAC) triazole annulation and sulfur(VI) fluoride exchange (SuFEx) catalysis are widely regarded as click reactions(2-4), providing rapid access to their products in yields approaching 100% while being largely orthogonal to other reactions. However, in the case of CuAAC reactions, the availability of azide reagents is limited owing to their potential toxicity and the risk of explosion involved in their preparation. Here we report another reaction to add to the click reaction family: the formation of azides from primary amines, one of the most abundant functional groups(5). The reaction uses just one equivalent of a simple diazotizing species, fluorosulfuryl azide(6-11) (FSO2N3), and enables the preparation of over 1,200 azides on 96-well plates in a safe and practical manner. This reliable transformation is a powerful tool for the CuAAC triazole annulation, the most widely used click reaction at present. This method greatly expands the number of accessible azides and 1,2,3-triazoles and, given the ubiquity of the CuAAC reaction, it should find application in organic synthesis, medicinal chemistry, chemical biology and materials science.

Polyimides (PI) generally have a high affinity for single-walled carbon nanotubes (SWNTs), but they suffer from poor solubility in most low boiling point organic solvents and low compatibility with common resins (such as epoxy) used in composites, limiting their suitability as dispersants. PI block copolymer systems containing reactive poly(ester carbonate) s have not yet been reported and are expected to act as effective reactive dispersing agents of SWNTs. Herein, PI-derived block copolymers are synthesized via ring-opening copolymerization of lactide (LA) (a control monomer) and allyl-bearing 2-methyl-2-(allyloxycarbonyl)-propylene carbonate (MAC) from the OH-terminal ends of the PI block to produce PLA-PI-PLA (TB1, a control) and PMAC-PI-PMAC (TB2). The allyl pendant group of TB2 allows further facile functionalization to form a third series of epoxidized (EP) derivatives, i.e. PMACEP-block-PI-block-PMACEP (TB3). TB3 copolymer when mixed with a conventional structural epoxy resin forms blends that do not show inferior tensile properties compared with the epoxy, which is unusual. Furthermore, the mixing solvent tetrahydrofuran (THF) can be readily evaporated off after forming the blends. TB3-dispersed (2 wt%) SWNTs added to epoxy increased the tensile strength, modulus, and elongation at break of the resulting nanocomposite films by 40%, 34%, and 26% respectively, compared to the baseline epoxy resin. Furthermore, when TB3b triblock-dispersed SWNTs in epoxy were combined with fuzzy carbon fibers, i.e. carbon nanotube-grafted-carbon fibers (CNT-g-CF), a synergistic interfacial strength reinforcement was observed, together with shifting of the failure mode from the matrix interphase to the carbon fiber-grafted nanotube interface. The ultimate interfacial shear strength between the TB3-dispersed SWNT-epoxy matrix and the fuzzy carbon fibers (i.e., fibers having carbon nanotubes grown on them) measured via single fiber pull-out tests was 100 MPa, which was ca. 11% improvement over the baseline unsized carbon fiber in neat epoxy. To our knowledge, this is the first evidence of a synergistic enhancement in interfacial properties when fuzzy carbon fibers are combined with a SWNT-reinforced epoxy using the new epoxidized TB3 nanotube dispersing agent that forms a strong covalent TB3-epoxy interface. The new functionalizable TB3 synthesis route introduced here is generalizable to other PI-based copolymers with diverse functionalities and solvent compatibilities.

An in situ formed cobalt catalyst is developed from cobalt(II)bromide, bis[2-(diisopropylphosphino)-4-methylphenyl]amine and zinc metal. The catalyst mediates the acceptorless dehydrogenative coupling of alcohols and amines into imines with the release of hydrogen gas and the transformation is applied to the synthesis of a variety of imines from different alcohols and amines. The mechanism is investigated with labelled substrates and based on the results a cobalt(I) PNP complex is believed to be the catalytically active species which abstracts hydrogen gas from the alcohol through a metal ligand bifunctional pathway.

A highly enantioselective iridium- or ruthenium-catalyzed intermolecular reductive amination/asymmetric hydrogenation relay with 2-quinoline aldehydes and aromatic amines has been developed. A broad range of sterically tunable chiral N,N’-diaryl vicinal diamines were obtained in high yields (up to 95%) with excellent enantioselectivity (up to >99% ee). The resulting chiral diamines could be readily transformed into sterically hindered chiral N-heterocyclic carbene (NHC) precursors, which are otherwise difficult to access. The usefulness of this synthetic approach was further demonstrated by the successful application of one of the chiral vicinal diamines and chiral NHC ligands in a transition-metal-catalyzed asymmetric Suzuki-Miyaura cross-coupling reaction and asymmetric ring-opening cross-metathesis, respectively.

A collection of potent antimicrobials consisting of novel 1,3-bis-benzoic acid and trifluoromethyl phenyl derived pyrazoles has been synthesized and tested for antibacterial activity. The majority of trifluoromethyl phenyl derivatives are highly potent growth inhibitors of Gram-positive bacteria and showed low toxicity to human cultured cells. In particular, two compounds (59 and 74) were selected for additional studies. These compounds are highly effective against Staphylococcus aureus as shown by a low minimum inhibitory concentration (MIC), a bactericidal effect in time-kill assays, moderate inhibition of biofilm formation as well as biofilm destruction, and a bactericidal effect against stationary phase cells representing non-growing persister cells. Multistep resistance assays showed a very low tendency for S. aureus and Enterococcus faecalis to develop resistance through mutation. Additionally, in vivo mouse model studies showed no harmful effects at doses up to 50 mg/kg using 14 blood plasma organ toxicity markers or TUNEL assay in liver and kidney. Investigations into the mode of action by performing macromolecular synthesis inhibition studies showed a broad range of inhibitory effects, suggesting targets that have a global effect on bacterial cell function.

DNA-encoded chemical library (DECL) screens are a rapid and economical tool to identify chemical starting points for drug discovery. As a robust transformation for drug discovery, palladium-catalyzed C-N coupling is a valuable synthetic method for the construction of DECL chemical matter; however, currently disclosed methods have only been demonstrated on DNA-attached (hetero)aromatic iodide and bromide electrophiles. We developed conditions utilizing an N-heterocyclic carbene-palladium catalyst that extends this reaction to the coupling of DNA-conjugated (hetero)aromatic chlorides with (hetero)aromatic and select aliphatic amine nucleophiles. In addition, we evaluated steric and electronic effects within this catalyst series, carried out a large substrate scope study on two representative (hetero)aryl bromides, and applied this newly developed method within the construction of a 63 million-membered DECL.
