Nickel-Catalyzed Decarbonyloxidation of 3-Aryl Benzofuran-2(3H)-ones to 2-Hydroxybenzophenones

We have developed a protocol to facilitate the nickel-catalyzed decarbonyloxidation of 3-aryl benzofuran-2(3H)-ones to 2-hydroxybenzophenones under mild conditions, which is an efficient approach for the decarbonyloxidation of lactones in organic synthesis. A diverse range of substrates can undergo C(O)-O/C(O)-C bond cleavage to generate the target products in good yields. These 2-hydroxybenzophenones can be converted into a variety of compounds via reactions such as esterification, cyclization, and reduction.

Highly Aromatic Flavan-3-ol Derivatives from Palaeotropical Artocarpus lacucha Buch.-Ham Possess Radical Scavenging and Antiproliferative Properties

Phytochemical investigation of leaves and stembark of Artocarpus lacucha collected in Thailand resulted in three yet undescribed isomeric flavan-3-ol derivatives (1-3), the four known compounds gambircatechol (4), (+)-catechin (5), (+)-afzelechin (6) and the stilbene oxyresveratrol (7). Compounds 1 to 3 feature 6/6/5/6/5/6 core structures. All structures were deduced by NMR and MS, while density functional theory (DFT) calculations on B3LYP theory level were performed of compounds 1 to 3 to support the stereochemistry in positions 2 and 3 in the C-ring. Possible biosynthetic pathways leading to 4 are discussed. The DPPH assay revealed high radical scavenging activities for 1 (EC50 = 9.4 +/- 1.0 mu mol mL(-1)), 2 (12.2 +/- 1.1), 3 (10.0 +/- 1.5) and 4 (19.0 +/- 2.6), remarkably lower than ascorbic acid (EC50 = 34.9) and alpha-tocopherol (EC50 = 48.6). A cytotoxicity assay revealed moderate but consistent antiproliferative properties of 1 in CH1/PA-1 (ovarian teratocarcinoma) and SW480 (colon carcinoma) cells, with IC50 values of 25 +/- 6 and 34 +/- 4 mu M, respectively, whereas effects in A549 (non-small cell lung cancer) cells were rather negligible. The performed DCFH-DA assay of 1 in the former cell lines confirmed potent antioxidative effects even in the cellular environment.

Substituted benzothiophene and benzofuran derivatives as a novel class of bone morphogenetic Protein-2 upregulators: Synthesis, anti-osteoporosis efficacies in ovariectomized rats and a zebrafish model, and ADME properties

The bone morphogenetic protein (BMP) pathway is a promising new target for the design of therapeutic agents for the treatment of low bone mass. This study optimized the structure of the anti-osteoporosis compound 38 by balancing its lipophilicity and improving its stability. Twenty derivatives which were not reported in the literature were designed and synthesized. The ovariectomized rat model of osteoporosis was selected to evaluate the therapeutic effects. Compound 125 showed better therapeutic efficacy than that of 38. We verified the anti-osteoporosis activity and BMP-2 protein upregulation after treatment with 125 in a zebrafish osteoporosis model. We found that 125 improved the ADME properties, therapeutic efficacy, and pharmacokinetics of the drug. Overall, we evaluated the anti-osteoporosis effects of the compounds of this type, preliminarily determined the target patient population, verified the mechanism of action, clarified the level of toxicity, and provided preliminary ADME data. We believe that these compounds can both correct bone loss that is already occurring in patients and have broad clinical applicability. (C) 2020 Elsevier Masson SAS. All rights reserved.

Modulation of benzofuran structure as a fluorescent probe to optimize linear and nonlinear optical properties and biological activities

The study presents the influence of structure modulation by introducing selected donor and acceptor substituents on optical properties of benzofuran used in biological imaging. As the starting form, 2-(5-formylbenzofuran-2-yl)acetamide described experimentally was used. This molecule contains an aldehyde group as reactive site, through which conjugation with protein occurs. Structure modulation was carried out by attaching additional electron-donating and electron-withdrawing substituents to the amino group, namely -NH2, -NHCH3, -NO2, -OH, and -OCH3. Studies have shown that the -NH2, -NHCH3, -OH, and -OCH(3)substituents do not induce a significant change in the position of maximum absorption and fluorescence relative to each other. They also do not change the parameters describing the nonlinear response. Only the presence of the -NO2 substituent results in significant solvatochromic shifts. Changing substituents also does not significantly affect the LD50 value, and all tested fluorescent probes should not be considered toxic to humans. Modulation of the benzofuran derivative structure also does not change the active center in which the biocomplex with the protein is formed. In each case, the conjugation takes place via LYS114. In addition, the study was prompted to analyze the linear and nonlinear optical properties of conjugates formed after the reaction with Concanavalin A.

Discovery of novel benzofuran scaffold as 4-hydroxyphenylpyruvate dioxygenase inhibitors

BACKGROUND 4-Hydroxyphenylpyruvate dioxygenase (HPPD) plays an important role in addressing the issue of plant protection research. This study sheds new light on the differences in molecular scaffold from commercialized HPPD inhibitors. RESULTS The compounds A1-A18 and B1-B27 were synthesized for in vitro and greenhouse experiments. The greenhouse experiment data indicated that compounds B14 and B18 displayed excellent herbicidal activity, which was higher compared to that of mesotrione. In vitro testing indicated that the compounds were HPPD inhibitors. Moreover, molecular simulation results show that the compounds B14, B18, and mesotrione shared similar interplay with surrounding residues, which led to a perfect interaction with the active site of Arabidopsis thaliana HPPD. Based on crop selectivity results, compounds B14 and B18 were selected for maize studies (injury <= 10%), indicating its potential for weed control in maize fields. CONCLUSION These results showed that the pyrazole-benzofuran structure could be used as possible lead compounds for the development of HPPD inhibitors.

Pd-Catalyzed Annulation of beta-Iodovinyl Sulfones with 2-Halophenols: A General Route for the Synthesis of 3-Sulfonyl Benzofuran Derivatives

The palladium-catalyzed annulation between beta-iodovinyl sulfones and 2-halophenols or 1-bromo-2-naphthol or 2-bromo-3-pyridinol is presented. The annulation process involving oxa-Michael addition-elimination and intramolecular Heck reaction leading to form 2,3-disubstituted benzofurans (aryl benzofuryl sulfones) in good to high yields. The regioselective tandem construction of C-O and C-C bonds has been achieved with a variety of substitution patterns. Moreover, the tandem process is reliable at gram-scale reactions and a plausible mechanism is also proposed.

Antineoplastic Activity In Vitro of 2-amino-5-benzylthiasol Derivative in the Complex with Nanoscale Polymeric Carriers

The main problems of contemporary chemotherapy are the insufficient efficacy of antitumor drugs and low selectivity of their action, development of multidrug resistance, and poor water solubility of antitumor drugs. One of the ways to improve the targeted delivery of drugs and increase their solubility is the use of polymeric nanoscale carriers. The newly synthesized thiazole derivative (N-(5-benzyl-1,3-thiazol-2-yl)-3,5-dimethyl-1-benzofuran-2-carboxamide, BF1) is cytotoxic in its activity towards some tumor cell lines. The aim of this study was to investigate the action of BF1 conjugated with novel polymeric carriers based on polyethylene glycol (PEG). The synthesized complexes exhibited a higher level of cytotoxicity towards specific tumor cell lines than the pure (unconjugated) thiazole derivative or/and doxorubicin (positive control). Complexes 4, 14 and 8, 18 were the most toxic to the human hepatocarcinoma HepG2 and the rat glioma C6 cell lines. Complex 6 exhibited a high level of toxicity towards human glioblastoma T98G and human promyelocytic leukemia HL-60 cell lines. Thus, complexes 4 and 14 based on poly(VEP-co-GMA)-graft-mPEG, complex 6 based on poly(PEGMA), and complexes 8 and 18 based on poly(PEGMA-co-DMM) selectively increase the toxic action of thiazole derivative BF1 towards tumor cells.
