The development of a Cu(I)/pyrazolylpyridineamine catalyst system for the hydroxylation of aryl halides

A catalyst system comprising of pyrazolylpyridineamine/Cu(I)/CsOH is reported. for the hydroxylation of aryl iodides and bromides with moderate to outstanding yields, without the use of an inert atmosphere. A comprehensive parameter optimisation study established optimum component concentrations: [Cu(MeCN)(4)]BF4 and 2-(1H-pyrazol-1-yl)-N-(pyridine-2-ylmethyl)ethan-1-amine (L01) (2 mol %), substrate (1 mmol), CsOH (4 mmol) and DMSO:H2O (1:1, 3 mL). Monitoring substrate conversion as a function of time revealed an induction period of 90 min, which could be eliminated through the initial in situ formation of the proposed [(L01)Cu-OH] intermediate. Eliminating the induction period resulted in complete conversion within one hour, with turnover numbers exceeding that of the benchmark catalyst system operating at an optimal catalyst loading of 0.05 mol %.

Synthesis and biological evaluation of 3-functionalized 2-phenyl- and 2-alkylbenzo[b]furans as antiproliferative agents against human melanoma cell line

The key function of microtubules and mitotic spindle in cell division make them attractive targets in anticancer therapy. In the present study, functionalized in 3 position 2-phenyl- and 2-alkylbenzo[b]furans were synthesized and evaluated as antitumor agents. Among the synthesized derivatives 13a, 13b and 14 exhibited the most potent antiproliferative activity against human melanoma A375 cell line with IC50 values of 2.85 mu M, 0.86 mu M, 0.09 mu M, respectively. The most promising compound defined was 14 with three methoxy groups in the 3-aroyl substituent and 7-methoxy group in 2-phenylbenzo[b]furan skeleton. Tubulin polymerization assay, confocal microscopy imaging and flow cytometry analysis revealed that 2-phenyl-3-aroylbenzo[b]furans (13a, 13b and 14) inhibited tubulin polymerization leading to disruption of mitotic spindle formation, cell cycle arrest in G2/M phase and apoptosis.

Application of Electrochemical Processes to Classical Iodocyclisation: Utility for Selectivity and Mechanistic Insight

The hazards and difficulties of handling elemental halogens such as I-2 can be circumvented through the electrochemical generation of these species in situ and ‘on-demand’. Advantages of this approach include the halogen being introduced into the reaction mixture at a steady rate, ensuring low concentrations to prevent halogenation of reactive aromatic rings. We also demonstrate that the Lewis acid required to promote this reaction, a Zn(II) salt, can also be generated in situ from a zinc-coated graphite electrode in a clean and energy-efficient manner. Mechanistic studies indicate an unusual pathway, which provides selectivity for the iodocyclisation without the often-problematic electrophilic aromatic iodination of the aryl ring.

Ultrasound Assisted Synthesis of 2-Substituted Benzofurans via One-Pot and Sequential Method: Their In Vitro Evaluation

Background: The 2-substituted benzofuran framework has attracted enormous attention due to its presence in a range of bioactive compounds and natural products. While various methods for the synthesis of 2-substituted benzofuran derivatives are known, several of them suffer from certain drawbacks. Objective: The main objective of this work was to explore a series of 2-(het)aryl substituted benzofurans derivatives for their cytotoxic properties against cancer cell lines in vitro. Methods: In our efforts, we have developed a one-pot synthesis of this class of compounds via sequential C-C coupling followed by C-Si bond cleavage and subsequent tandem C-C/C-O bond-forming reaction under ultrasound irradiation. The methodology involved coupling of (trimethylsilyl)acetylene with iodoarenes in the presence of 10% Pd/C-Cul-PPh3-Et3N in MeOH followed by treating the reaction mixture with K2CO3 in aqueous WON and finally coupling with 2-iodophenol. A variety of 2-substituted benzofurans were synthesized using this methodology in good yield. All the synthesized compounds were tested in vitro against two cancer cell lines, e.g. MDAMB-231 and MCF-7 cell lines subsequently against SIRT1. Results: The benzofuran derivative 3m showed encouraging growth inhibition of both MDAMB-231 and MCF-7 cell lines and significant inhibition of SIRT1. The compound 3m also showed a concentration-dependent increase in the acetylation of p53. Conclusion: Our efforts not only accomplished a one-pot and direct access to 2-(het)aryl substituted benzofurans but also revealed that the benzofuran framework presented here could be a potential template for the identification of potent inhibitors of SIRT1.

Synthesis and evaluation of methoxy substituted 2-benzoyl-1-benzofuran derivatives as lead compounds for the development adenosine A(l) and/or A(2A) receptor antagonists

A series of fourteen methoxy substituted 2-benzoyl-1-benzofuran derivatives were synthesised and their affinities determined for adenosine A(1) and A(2A) receptors via radioligand binding assays to establish the structure activity relationships pertinent for A(1) and A(2A) affinity. Compound 3j (6,7-dimethoxybenzofuran-2-yl)(3-methoxyphenyl) methanone exhibited A(1) affinity (A(1)K(i) (rat) = 6.880 mu M) as well as A(2A) affinity (A(2A)K(i) (rat) = 0.5161 mu M). Compounds 3a-b & 3i-k exhibited selective affinity towards A(1) with K-i values below 10 mu M. The results indicate that C6,7-diOCH(3) substitution on ring A in combination with meta (C3′)-OCH3 substitution on ring B is beneficial for A(1) and A(2A )affinity and activity. Compounds 3a-b & 3j-k showed low cytotoxicity. Upon in vitro and in silico evaluation, compound 3j may be considered lead-like (i.e. a molecular entity suitable for optimization) and, thus, of value in the design of novel, potent and selective adenosine A(1) and A(2A) receptor antagonists.

Synthesis of New 4-Oxo-Tetrahydroindol Derivatives by Using Chemical and Microbial Biotransformation Methods

An efficient method for the preparation of 4-oxo-4,5,6,7-tetrahydroindoles was successfully applied to the synthesis of N-substituted 4-oxo-4,5,6,7-tetrahydroindoles (4) and (5) for the first time. Manganese(III) acetate-mediated acetoxylation of (2) produced 4,5,6,7-tetrahydro-4-oxo-7,7-dimethyl benzofuran-5-yl acetate (3) for the first time in the literature. Then 4,5,6,7-tetrahydro-4-oxo-7,7-dimethyl benzofuran-5-yl acetate was converted to its indole derivative (4) via benzyl amine. Thus, 1-benzyl-5-hydroxy-7,7-dimethyl-6,7-dihydro-1H-indol-4(5H)-one (4) was obtained in good yields. Furthermore, biotransformation of pharmacologically interesting compounds such as 5-hydroxy-7,7-dimethyl-6,7-dihydro-1H-indol-4-(5H)-one (5) were also obtained by biotransformation reaction using Aspergillus niger.

Inhibitory Effect of (2R)-1-(1-Benzofuran-2-yl)-N-propylpentan-2-amine on Lung Adenocarcinoma

BPAP is a potent enhancer substance with catecholaminergic and serotoninergic activity in the brain. It was discovered that it is also effective against certain types of experimental cancers, showing the most promising results in case of lung cancer. That is why we tested its efficacy in two different doses in a newly developed EGFR wild type mouse lung adenocarcinoma xenograft model. Experiments were conducted on FVB/N and SCID mouse strains treated with low and high dose of BPAP. Body weight, survival, and tumor volumes were recorded. Furthermore, the activity of major signaling pathways of NSCLC such as MAPK and Akt/mTOR as well as cell cycle regulation were determined. Significant inhibition of tumor growth was exerted by both doses, but the mechanism of action was different. High dose directly inhibited, whereas low dose activated the main signaling pathways. Exposure to low dose BPAP resulted in elevated activity of the mTOR pathway together with p16(INK)-induced cell cycle arrest, a typical feature of geroconversion, a senescent state characterized by loss of cell proliferation. Finally the events culminated in cell cycle inhibition point in case of both doses mirrored by the decrease of cyclin D1, CDK4 and PCNA. In addition, BPAP treatment had a beneficial effect on bodyweight suggesting that the compound at least in part is able to compensate the cancer-related wasting. In view of the low toxicity and confirmed antitumor effect of BPAP against experimental lung adenocarcinoma, this novel compound deserves further attention.
