Study of molecular structure and assignments of fundamental modes of 2-ethylpyridine-4-carbothioamide by density functional methods

Indian Journal of Physics, 2013
The FT-IR and UV spectra of 2-ethylpyridine-4-carbothioamide have been recorded. The structure and spectroscopic data of the molecule in ground state have been calculated using AM1, PM3 semi-empirical methods, ab initio Hartree–Fock and density functional theory (B3LYP, B3PW91) methods by employing 6-31+ G (d, p) basis sets.

Synthesis, antimicrobial screening, and docking study of new 2‐(2‐ethylpyridin‐4‐yl)‐4‐methyl‐N‐phenylthiazole‐5‐carboxamide derivatives

Journal of the Chinese Chemical Society, 2020
AbstractA series of new 2‐(2‐ethylpyridin‐4‐yl)‐4‐methyl‐N‐phenylthiazole‐5‐carboxamide derivatives (5a‐l) were synthesized and evaluated for their in vitro antimicrobial activities. Among the screened compounds, 5b, 5d, 5e, 5f, and 5j have shown promising antimicrobial activities against both bacterial and fungal pathogens.

Protective effects of melatonin and memantine in human retinal pigment epithelium (ARPE-19) cells against 2-ethylpyridine-induced oxidative stress: implications for age-related macular degeneration

Cutaneous and Ocular Toxicology, 2017
To investigate the possible protective effects of melatonin and memantine (MMT) against 2-ethylpyridine (2-EP)-induced oxidative stress and mitochondrial dysfunction in human RPE (ARPE-19) cells in vitro.The ARPE-19 cells were divided into seven groups. Oxidative stress was triggered by incubating the ARPE-19 cells with 30 μM of 2-EP for 24 h.

Cooperative C(sp³)–H and C(sp²)–H Activation of 2-Ethylpyridines by Copper and Rhodium: A Route toward Quinolizinium Salts

ACS Catalysis, 2015
A method for the synthesis of substituted quinolizinium salts from 2-ethylpyridines and alkynes is demonstrated. The transformation is conveniently achieved using 1 mol % of a Rh(III) catalyst along with an excess amount of copper(II) salt. The reaction gives high product yields with broad substrate scope and functional group tolerance.

Spin Crossover Iron(II) Complexes of (2-Methylimidazol-4-yl)methylideneamino-2-ethylpyridine: 2:1 [Fe(HLMe)2](PF6)2 and 3:1 [Fe(HLMe)3](PF6)2

Chemistry Letters, 2007
Abstract (2-Methylimidazol-4-yl)methylideneamino-2-ethylpyridine (HLMe) functions as either bidentate or tridentate ligand to FeII ion to produce the 2:1 complex [Fe(HLMe)2](PF6)2 (1) and the 3:1 complex [Fe(HLMe)3](PF6)2 (2). Both complexes showed spin crossover (SCO) behaviors; 1 exhibited a gradual SCO between HS and (HS + LS)/2 and 2

[Cytoprotective properties of 3-oxy-6-methyl-2-ethylpyridine succinate in cell cultures].

Eksperimental'naia i klinicheskaia farmakologiia, 2007
Tests on calf coronary vessel cells (CVC) cultures showed that 3-oxi-6-methyl-2-ethylpiridine succinate (OMEPS) in dozes within 5.0-10.0 microg/ml did not decrease proliferation index, monolayer development, and viability factor. OMEPS also did not increase cytotoxicity index and did not change cytomorphological characteristics of the culture.

NH/π Interaction in a Spin-Crossover Complex [Fe^II(HL^Me)₂](BPh₄)₂·2CH₃CN (BPh₄^- = Tetraphenylborate; HL^Me = 2-Methylimidazol-4-yl-methylideneamino-2-ethylpyridine)

Inorganic Chemistry, 2005
Three FeII complexes, [Fe(HLR)2](BPh4)2.solvent (R=H, Me, Ph), were synthesized, where BPh4-=tetraphenylborate and HLR=2-substituted-imidazol-4-yl-methylideneamino-2-ethylpyridine. The magnetic susceptibility measurements in 5-300 K revealed that [Fe(HLH)2](BPh4)2.H2O, [Fe(HLMe)2](BPh4)2.2CH3CN, and [Fe(HLPh)2](BPh4)2.CH3CN are low-spin (LS), spin ...
