[PMID: 38840415 DOI: 10.1002/cplu.202400172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 05/20/2024] [Accepted: 06/03/2024] [Indexed: 06/07/2024]
Abstract
Herein, a Cs2CO3-promoted N-alkylation of 3-cyano-2(1H)-pyridones containing alkyl groups with diverse alkyl halides to synthesize N-alkyl-2-pyridones over O-alkylpyridines is reported. The use of alkyl dihalides resulted in complex mixtures of N- and O-alkylated products. The primary factor influencing regioselectivity in these reactions is the electronic effects of substituents on the 2(1H)-pyridone ring, as evidenced by the preferential formation of O-alkylpyridines upon the introduction of aryl groups. Remarkably, we efficiently employed CuAAC and Ti(Oi-Pr)4-catalyzed amidation reactions to functionalize N-alkyl-2-pyridones containing propargyl and ester groups, leading to the synthesis of 1,2,3-triazoles and amides, respectively. Moreover, O-alkylpyridines 10 b and 10 d displayed remarkable selectivity toward the A-498 renal cancer cell line with growth inhibition percentages (%GI) of 54.75 and 67.64, respectively. The binding modes of compounds 10 b and 10 d to the PIM-1 kinase enzyme were determined through molecular docking studies.

Abstract
The synthesis and crystal structure of the title compound, C22H14N2O, are described. The title compound was synthesized by a three-component one-pot reaction in DMSO involving chalcone, cyano-acetamide and elemental sulfur as catalyst. The compound was characterized by spectroscopic methods and single-crystal X-ray diffraction. The structure consists of inversion-related dimers produced by N-H⋯O hydrogen bonding, which further inter-act through π-π contacts.

Abstract
BACKGROUND The continuous need for new anticancer drugs is never-ending task due to cancer resistance to the existing drugs. OBJECTIVE This article aimed to design, synthesis, characterization, and anticancer evaluation of cyanopyridines, pyridopyrazolopyrimidines and pyridopyrazolotriazines. METHODS Anticancer activity of the synthesized compounds was determined using MTT assay against three cancer cell lines, namely liver cancer cell line (HepG-2), pancreatic cancer cell line (PANC-1), non-small lung cancer cell line (A-549) and normal fibroblast. RESULTS AND DISCUSSION A series of 3-cyanopyridines (2a,b, 4, 5, 9), pyridopyrimidine (10), pyridopyrazolopyrimidines (11a-c, 12a,b, 18), pyrazolopyridine salt (13) and pyridopyrazolotriazines (16a,b) were synthesized from 3-cyano-4,6-dimethyl-2-pyridone. The synthesized compounds were evaluated in vitro for their anticancer activity and their chemical structures were determined by elemental analysis and spectroscopic data. CONCLUSION Some of the synthesized compounds showed remarkable anticancer activities, especially 11a exhibited superior potency to the reference drug cisplatin against A-549 (IC50 = 9.24 μg mL-1 compared to 11.76 μg mL-1 for reference drug) and was found to be safe (IC50 = 66 μg mL-1) for normal fibroblast. Furthermore, compound 16a displayed the highest activity among the tested compounds against HepG-2 (IC50 = 6.45 μg mL-1 equipotent to cisplatin) with the highest safety profile for normal fibroblast (IC50=113.97 μg mL-1).

Abstract
This work represents the use of N-3-(3,5-dimethyl-1H-pyrazol-1-yl)-3-oxopropanenitrile as a cyanoacetylating agent for the synthesis of cyanoacetamide benzoic acid and benzophenone derivatives by two different methods, namely, conventional heating and ultrasonication. The cyanoacetamide derivatives were subjected to cyclization to produce N-substituted 2-pyridone derivatives under conventional heating and by an ultrasonic method as well. The ultrasonic method afforded the products in less reaction time with high yields and purities compared to the conventional method, as observed from their spectral data. N-(4-Carboxy phenyl)-4,6-dimethyl-3-cyano-2-pyridone was coupled with different amino acid esters by the OxymaPure/DIC methodology under traditional and ultrasonic conditions. Again, ultrasonication assisted the coupling step and afforded the products with higher yields and purities compared to the traditional method. Fourier transform infrared spectroscopy, NMR (1H and 13C), elemental analysis, and LC-MS were used to determine the structures of all compounds. Finally, a feature of this protocol is exploring the utilization of ultrasonication as an eco-friendly alternative conventional heating method for N-cyanoacylation and synthesis of N-substituted pyridinone derivatives and as a coupling method for the formation of an amide bond, which might be of interest for many researchers.

Abstract
The 1,3-dipolar cycloaddition reaction of bis-hydrazonyl chlorides with methyl propiolate afforded dimethyl 1,1¢-aryl-3,3`-bipyrazole-4,4`-dicarboxylates (5a,b). Heating the later compound 5a with a mixture of HCl/AcOH gave 3,3`-bipyrazole-5,5`-dicarboxylic acid derivative 6. Treatment of the hydrazonoyl chloride (1a) and 3,3`-bipyrazole-5,5`-dicarboxylic acid (6) with palladium(II) chloride gave the corresponding Pd-complexes 7 and 8, respectively. The catalytic activity of the prepared Pd-complexes was examined in the Suzuki cross-coupling reaction of phenylboronic acid with activated and deactivated aryl(hetaryl) bromides. The catalyst system provides very good to excellent yields, 85-94%. The structures of the obtained products were established from their elemental analysis, spectral data, XPS, EDX, and single crystal X-ray crystallography. Crystal data for C10H7N2O2 (6): triclinic, space group P-1 (no. 2), a = 3.9956(10) Å, b = 9.8917(18) Å, c = 10.810(3) Å, α = 94.167(15)°, β = 94.979(19)°, γ = 98.953(15)°, V = 418.83(16) Å3, Z = 2, T = 296.(2) K, μ(Cu Kα) = 0.887 mm-1, Dcalc = 1.484 g/cm3, 5469 reflections measured (11.72° ≤ 2Θ ≤ 133.24°), 1420 unique (Rint = 0.0633, Rsigma = 7.24%) which were used in all calculations. The final R1 was 0.1055 (>2sigma(I)) and wR2 was 0.3620 (all data).

Abstract
The selective O-benzylation of 2-oxo-1,2-dihydropyridines plays a critical role in organic synthesis of natural products and biological active molecules. Herein we report a novel ternary system of ZnO, ZnCl2 and N,N-diisopropylethylamine (DIEA), that is highly effective for selective O-benzylation of 2-oxo-1,2-dihydropyridines using abundant substituted benzyl halides and related substituted 2-oxo-1,2-dihydropyridines compounds. This process allows access to a variety of O-benzyl products under mild reaction conditions, which are important synthetic intermediates in the protection of functional groups, and represents a new method toward the development for the O-benzylation of 2-oxo-1,2-dihydropyridines.
