Synthesis and evaluation of 3-anilino-quinoxalinones as glycogen phosphorylase inhibitors

A series of 3-anilino-quinoxalinones has been identified as a new class of glycogen phosphorylase inhibitors. The lead compound 1 was identified through high throughput screening as well as through pharmacophore-based electronic screening. Modifications were made to the scaffold of 1 to produce novel analogues, some of which are 25 times more potent than the lead compound.

Effect of heat curing on antifungal activities of anise oil and garlic oil against Aspergillus niger on rubberwood

The effect of heat curing (30-100 C) on the antifungal activity of rubberwood impregnated with anise oil and garlic oil (10-100 mul ml-1) against Aspergillus niger was examined. Essential oil constituents left within the rubberwood after the heat curing and after incubation were analyzed by GC-MS. Response surface methodology (RSM) with a central composite face-centered (CCF) design was employed to evaluate the time needed for initiation of mold growth. The mathematical models containing only significant parameters (p ? 0.05) as functions of treatment temperature and essential oil concentration were obtained. Heat curing adversely and positively influenced the antifungal activities of anise oil and garlic oil, respectively. Such thermal effect was more pronounced at a higher concentration of essential oil. Decomposition of trans-anethole and estragole in anise oil and formation of diallyl disulfide in garlic oil by heat was proposed as the agent responsible for temperature dependencies of the essential oil antifungal activities observed.

Visible-light mediated carbamoyl radical addition to heteroarenes

The generation of carbamoyl radicals, followed by their addition to heteroarenes, was performed under mild conditions through a metal-free photocatalyzed decarboxylation of oxamic acids. The process has been applied to the carbamoylation of heteroaromatic bases using alpha-aminoacid-derived oxamic acids, leading to the corresponding amides without racemization.

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.

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.

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.
