The effects of the diphenyl ether herbicides HOE 29152 (methyl-2[4-(4-trifluoromethoxy) phenoxy] propanoate) and nitrofluorfen (2-chloro-1-[4-nitrophenoxy]-4-[trifluoromethyl]benzene) on photosynthetic electron transport have been examined with pea seedling and spinach chloroplasts. Linear electron transport (water to ferricyanide or methylviologen) is inhibited in treated chloroplasts, but nei...

The objective of this work is to establish the structural requirements of flavonoids for appreciable radical-scavenging activity (RSA) and elucidate a comprehensive mechanism that can explain their activity. To this end, the RSA of 52 flavonoids against 2,2-diphenyl-1-picrylhydrazyl was determined. The relative change in energy (DeltaH(f)) associated with the formation of various flavonoidal an...

Organoselenium compounds have been pointed out as therapeutic agents. In contrast, the potential therapeutic aspects of tellurides have not yet been demonstrated. The present study evaluated the comparative toxicological effects of diphenyl diselenide (PhSe)2 and diphenyl ditelluride (PhTe)2 in mice after in vivo administration. Genotoxicity (as determined by comet assay) and mutagenicicity wer...

The asymmetric unit of the title complex, [Ag(4)W(2)S(8)(C(25)H(22)P(2))(3)]·2C(3)H(7)NO, tris-[μ(2)-bis-(diphenyl-phosphino)meth-ane]-3:6κ(2)P:P';4:5κ(2)P:P';5:6κ(2)P:P'-μ(5)-sulfido-2:3:4:5:6κ(5)S-μ(3)-sulfido-1:3:4κ(3)S-tetra-μ(2)-sulfido-1:3κ(2)S;1:4κ(2)S;2:5κ(2)S;2:6κ(2)S-disulfido-1κS,2κS-tetra-silver(I)ditungsten(VI) N,N-dimethyl-formamide disolvate, contains two [WS(4)](2-) anions, four...

The title compound, [Mo(2)(C(5)H(5))(2)(C(12)H(11)P)(2)(CO)(4)]·C(6)H(14), is a centrosymmetric Mo complex in which two Mo atoms are connected by an Mo-Mo bond [3.2072 (12) Å]. Each Mo atom is coordinated by an η(5)-cyclo-penta-dienyl ligand, two carbonyl ligands and a diphenyl-phosphine ligand in a piano-stool fashion.

A series of 1-(2-chloro-5-nitrophenyl)-3-phenyl-2-propenones were synthesized from 2-chloro-5-nitroacetophenone with various substituted benzaldehydes by crossed-Aldol condensation. The synthesized compounds have been characterized by their physical constants and spectral data. The antimicrobial activities of synthesized 1, 3-diphenyl-2-propenone compounds have been evaluated by Kirby-Baur disc...
