Synthesis and characterization of polyaromatic azine derivatives of (eta5-C5H5) Fe(CO)2 and (eta5-C9H7) Fe(CO)2

The synthesis and characterization of 14 monometallic derivatives of quinoline, quinoxaline, quinazoline and tetraazolo<1,5-A>quinoline and a bimetallic derivative of quinoxaline are reported. These species were prepared in 11 to 88% isolated yields by metathesis reactions between NaFp or NaFp? (where Fp = (eta5 – C5H5)Fe(CO)2 and Fp? = (eta5 – indenyl)Fe(CO)2 ) and the appropriate chlorine substituted polyaromatic azines. These reactions are highly regioselective and generally produce a single organometallic product having the organometallic substituent(s) bonded to the more highly activated azine ring. The structures of three representative examples were confirmed by their X-ray crystal structures, which are reported for the title complexes 4-[(eta5-cyclopentadienyl)irondicarbonyl]-7-chloroquinoline (C16H10ClFeNO2; a = 7.608(1)A, b = 12.006(1)A, c = 15.664(1)A, V = 1431A3; orthorhombic; P212121; Z =4), 2-[(eta5-cyclopentadienyl)irondicarbonyl]-3-chloroquinoxaline (C15H9ClFeN2O2; a = 15.291(3) A, b = 6.561(2) A, c = 14.541(4) A, beta = 106.891(21), V= 1395.9A3; monoclinic; P21/c; Z = 4), and 2-[(eta5-indenyl)irondicarbonyl]-3-chloroquinoxaline (C19H11ClFeN2O2; a = 19.131(2)A, b = 6.688(1)A, c = 13.515(2) A, beta= 101.569(11), V = 1694.1 A3; monoclinic; P21/c; Z = 4). The bimetallic quinoxaline derivative 2,3-[(C5H5)2Fe2(CO)4]-quinoxaline has orrto-substituted organometallic groups and the spectroscopic data suggest that it has an unusual structure in solution, perhaps involving bridging cyclopentadienyl and carbonyl ligands.

Synthesis and biological evaluation of new 3-(4-substituted phenyl)aminoquinoxaline derivatives as anticancer agents

Quinoxaline derivatives 4-11 were synthesized and evaluated for their in vitro growth inhibitory activities against liver carcinoma cell line (HEPG2) using the sulforhodiamine B assay. The synthesis was achieved by reaction of 2,3-dichloroquinoxalines 2a,b with 4-aminoacetophenone to give the corresponding compounds 3a,b. Claisen-Schmidt condensation reaction of 3a,b with furfuraldehyde gave enones 4a,b, which were transformed into pyridines 6a,b, 8a,b, isoxazolines 9a,b, pyrazolines 10a-d, and pyrimidines 11a,b via several synthetic routes. Virtual screening was carried out by molecular modeling evaluation of the designed compounds. Biological evaluation of the prepared compounds showed that most of the synthesized compounds exhibit more than 50% growth inhibitory.

N,N?-Dihydrotetraazapentacenes (DHTA) in thin film transistors

The synthesis and structural properties of three N,N?-dihydrotetraazapentacenes (DHTA) are described. The different substitution pattern (H, F, Cl) of the dihydrotetraazapentacene body exhibited a significant effect on the optical, electronic and morphological properties of the derivatives in thin films. The synthesised materials were investigated as active layers in top gate/bottom contact (BC/TG) transistors. The transistor performance of the dichlorinated derivative was almost independent on the processing conditions with an average hole mobility of ?0.04 cm2 V-1 s-1 and best mobility values ranging from 0.07 to 0.11 cm2 V-1 s-1. Each of the three derivatives was found to exhibit an individual packing motif in solution grown crystals, determined by single crystal X-ray analysis. Surprisingly, for all three materials a different polymorph formed in spin cast films explaining the observed morphology and FET performance.

Design, Synthesis, and Characterization of Quinoxaline Derivatives as a Potent Antimicrobial Agent

A series of quinoxalinone derivatives were synthesized by the reaction of o-phenylenediamine with oxalic acid to yield 1, 4-dihydro quinoxaline-2, 3-dione (1) and then treated with thionyl chloride to yield 2, 3 dichloro quinoxaline (2). This was further reacted with hydrazine hydrate to produce 2, 3-dihydrazinyl quinoxaline (3). This was finally reacted with substituted aromatic aldehydes to produce 2,3-bis[2-(sustituted benzylidine) hydrazinyl] quinoxalines (4). These quinoxalinone derivatives were characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy and MASS spectral data. All the synthesized compounds were evaluated for their antimicrobial activity. The results of the antimicrobial study revealed that compounds 4c, 4d, and 4i were active and exhibited better inhibitory activities as compared to standard drug ciprofloxacin. The results were further checked with protein legend interaction by using docking studies, and all the compounds exhibited good docking scores between ?8.72 and ?11.29?kcal/mol against dihydrofolate reductase protein fragment from Staphylococcus aureus (PDB ID-4XE6). Among all compound, 4c has shown maximum docking score and found in agreement to in vitro studies.
