Multigram Synthesis of BMS-929075, an Allosteric, Palm Site Inhibitor of HCV NS5B Replicase, Involving the Synthesis of a Highly Functionalized Benzofuran through a Telescoped Process

An efficient scale-up synthesis of 4-fluoro-2-(4-fluorophenyl)-N-methyl-5-(2-methyl-5-(1-(pyrimidin-2-yl)cyclopropylcarbamoyl)phenyl)benzofuran-3-carboxamide (BMS-929075), an allosteric, palm site inhibitor of the HCV NSSB replicase, is described. The highlights of the process involve (a) the copper-mediated, one-pot synthesis of 2-(3-bromo-2-fluoro-6-methoxyphenyl)acetic acid (21) from regiospecifically lithiated 1-bromo-2-fluoro-4-methoxybenzene (13) and ethyl 2-bromoacetate (18); and (b) the formation of the highly functionalized benzofuran core 26 through a chromatography-free, telescoped process that proceeds via acylation and a subsequent concomitant demethylation and Boc deprotection using BBr3, followed by an acid-catalyzed cyclization from Boc-protected 2-(3-bromo-2-fluoro-6-methoxyphenyl)-N-methylacetamide 23. This process was applied to the preparation of 110 g of high-quality BMS-929075 to enable preclinical toxicology studies.

Preclinical Evaluation of Amphihevir, a First-in-Class Clinical Hepatitis C Virus NS4B Inhibitor

Amphihevir, a benzofuran derivative, is the first reported hepatitis C virus (HCV) nonstructural protein 4B (NS4B) inhibitor that has advanced to clinical trials (currently in phase 1b trial [CTR20170632]). Here, we report the results of a preclinical study of its potency, toxicity, selectivity, drug metabolism and pharmacokinetics (DMPK), and safety profiles. Amphihevir displayed good antiviral activities against genotype 1a (50% effective concentration [EC50) of 0.34 nM) and genotype 1b (EC50 of 1.97 nM) replicons and no cytotoxicity in 12 cell lines derived from animals and humans. Amphihevir was found to be inactive against other viruses, human kinases, and G protein-coupled receptors (GPCRs), which implies its good selectivity. A 9-day long-term treatment of genotype 1b replicons with amphihevir resulted in a 3.8 Log(10) decline of the hepatitis C viral RNA at a concentration of 25x EC50. Drug resistance screening showed that mutations occurred at H94, F98, and V105 of NS4B, which mediated the resistance to amphihevir. This result suggests that NS4B is the main target of amphihevir. There was no cross-resistance between amphihevir and NS5A, NS3/4A, and NS5B inhibitors, suggesting that amphihevir in combination with other anti-hepatitis C virus drugs could be used to treat hepatitis C, as proven by studies of amphihevir and other hepatitis C virus inhibitors. Pharmacokinetic studies demonstrated that amphihevir has good oral bioavailability and appropriate half-life (t(1/2)) in rats and dogs, thereby supporting its use once per day. Finally, amphihevir showed good safety profiles in rats and dogs. The results shed light on the use of amphihevir as a potential treatment option for chronic hepatitis C patients.

Directed Evolution of P450 BM3 towards Functionalization of Aromatic O-Heterocycles

The O-heterocycles, benzo-1,4-dioxane, phthalan, isochroman, 2,3-dihydrobenzofuran, benzofuran, and dibenzofuran are important building blocks with considerable medical application for the production of pharmaceuticals. Cytochrome P450 monooxygenase (P450) Bacillus megaterium 3 (BM3) wild type (WT) from Bacillus megaterium has low to no conversion of the six O-heterocycles. Screening of in-house libraries for active variants yielded P450 BM3 CM1 (R255P/P329H), which was subjected to directed evolution and site saturation mutagenesis of four positions. The latter led to the identification of position R255, which when introduced in the P450 BM3 WT, outperformed all other variants. The initial oxidation rate of nicotinamide adenine dinucleotide phosphate (NADPH) consumption increased approximate to 140-fold (WT: 8.3 +/- 1.3 min(-1); R255L: 1168 +/- 163 min(-1)), total turnover number (TTN) increased approximate to 21-fold (WT: 40 +/- 3; R255L: 860 +/- 15), and coupling efficiency, approximate to 2.9-fold (WT: 8.8 +/- 0.1%; R255L: 25.7 +/- 1.0%). Computational analysis showed that substitution R255L (distant from the heme-cofactor) does not have the salt bridge formed with D217 in WT, which introduces flexibility into the I-helix and leads to a heme rearrangement allowing for efficient hydroxylation.

High-Energy Proton-Beam-Induced Polymerization/Oxygenation of Hydroxynaphthalenes on Meteorites and Nitrogen Transfer from Urea: Modeling Insoluble Organic Matter?

Formation and structural modification of oxygenated polycyclic aromatic hydrocarbons (oxyPAHs) by UV irradiation on minerals have recently been proposed as a possible channel of PAH transformation in astrochemical and prebiotic scenarios of possible relevance for the origin of life. Herein, it is demonstrated that high-energy proton-beam irradiation in the presence of various meteorites, including stony iron, achondrite, and chondrite types, promotes the conversion of two representative oxyPAH compounds, 1-naphthol and 1,8-dihydroxynaphthalene, to complex mixtures of oxygenated and oligomeric derivatives. The main identified products include polyhydroxy derivatives, isomeric dimers encompassing benzofuran and benzopyran scaffolds, and, notably, a range of quinones and perylene derivatives. Addition of urea, a prebiotically relevant chemical precursor, expanded the range of identified species to include, among others, quinone diimines. Proton-beam irradiation of oxyPAH modulated by nitrogen-containing compounds such as urea is proposed as a possible contributory mechanism for the formation and processing of insoluble organic matter in meteorites and in prebiotic processes.

Electrochemical Assessment of EC and ECE Mechanisms for Caffeic Acid in the Presence of Aromatic Amines

In this work, electrochemical behavior of caffeic acid (CA) in the absence and presence of aromatic amines such as 4-amino-1,3-dimethyluracil (4A-DMU), p-toluidine (p-TI) and sulfacetamide (SA) has been investigated using cyclic voltammetry technique in 0.15 M sodium acetate solution/ethanol (80:20, v/v) mixture. The effect of different parameters such as concentration and scan rate indicated that the oxidation mechanism of caffeic acid (CA) in the presence of aromatic amines can be EC and ECE. At the working electrode surface, CA is oxidized to correponding o-benzoquinone (CA(OX)) through two electrons and two protons process. The Michael-type addition reaction has occurred between o-benzoquinone and aromatic amines. In the second cycle, compared to CA oxidation peak, a new oxidation peak appear in negative potentials because of the electron-donating properties of amines. The cyclic voltammetry technique can recognize chemical and electrochemical processes in solution and electrode surface, respectively.

Synthesis and biological evaluation of a new series of benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides as potential alpha-glucosidase inhibitors

A series of new benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides 12a-n as potential anti-alpha-glucosidase agents were designed and synthesized. alpha-Glucosidase inhibition assay demonstrated that all the synthesized compounds 12a-n (half-maximal inhibitory concentration [IC50] values in the range of 40.7 +/- 0.3-173.6 +/- 1.9 mu M) were more potent than standard inhibitor acarbose (IC50 = 750.0 +/- 12.5 mu M). Among them, the most potent compound was compound 12c, with inhibitory activity around 19-fold higher than acarbose. Since the most potent compound inhibited alpha-glucosidase in a competitive mode, a docking study of this compound was also performed into the active site of alpha-glucosidase. In vitro and in silico toxicity assays of the title compounds were also performed.

Novel Meroterpenoids from Hypericum patulum: Highly Potent Late Na(v)1.5 Sodium Current Inhibitors

Hypulatones A and B (1 and 2), two racemic meroterpenoids possessing an unprecedented spiro[benzofuran-2,1′-cycloundecan]-4′-ene-4,6(5H)-dione core, were characterized from Hypericum patulum. Compound 2 was found to significantly inhibit the late current of Na(v)1.5 (late I-Na, IC50 = 0.2 mu M). Importantly, 2 exhibited remarkable separation (>100-fold) of late I-Na relative to peak I-Na and notable selectivity over Ca(v)3.1, K(v)1.5, and hERG. 1 showed comparable inhibition on late I-Na compared to that of 2 with poorer selectivity.
