A new Z' = 1 crystal structure of quinoxaline (or 1,4-diaza-naphthalene), C(8)H(6)N(2), with one-fifth the volume of the earlier known Z' = 5 structure was obtained by means of an in situ cryocrystallization technique.

BACKGROUND 1,2,4-Triazole3-thiones are good scaffolds for preparation of new lead compounds. Their derivatives attracted the attention of chemists due to their wide spectrum of biological activities. Alkylsulfanyl-1,2,4-triazoles have three nucleophilic sites (nitrogens) ready for reaction with electrophiles. Herein, new regioselective isomers were synthesized by the reaction of benzylsulfanyl-...

We evaluated the effects of 23 insecticides and 9 fungicides on mite Neoseiulus barkeri(Hughes)collected from melon gerbera greenhouses. The nitenpyram, acetamiprid, flufenoxuron, chlorantraniliprole, pyridalyl, acequinocyl, cyenopyrafen, cyflumetofen, pyflubumide, fungicide flutianil+mepanipyrim had no effect survival fecundity adult females. In contrast, spinosad, spinetoram, abamectin, emame...

Cyclophilin J (CyPJ), also called peptidylprolyl isomerase like 3, has been identified as a novel member of the cyclophilin family. Our previous research has resolved the three-dimensional structure of CyPJ and demonstrated the peptidylprolyl cis-trans isomerase (PPIase) activity of CyPJ, which can be inhibited by the common immunosuppressive drug cyclosporine A (CsA). Importantly, CyPJ is upre...

3-(l-Halo-2-oxo-2-substitutedethyl)-2(lH)quinoxalinones, Furo[2,3-b]quinoxalines An efficient method for the synthesis of furo[2,3-b]quinoxalines has been devised. Thus, 3-halo-2-arylfuro[2,3-b]quinoxalines, 5a-5c were synthesized by the action of conc. H2SO4 on 3-(l-halo-2-oxo-2-arylethyl)-2(lH)quinoxalinones, 3b, 3c and 3f respectively. When 3-(1 -halo-2-oxo-2-substitutedethyl)-2(1H)quinoxali...
