In course of our screening for new secondary metabolites from ecological niche specialized, phytopathogenic fungi, the plant pathogen Elsinoё pyri, strain 2203C, was found to produce four novel compounds (1-4), which were named elsinopirins A-D, in addition to the known metabolite elsinochrome A (5). After isolation by preparative high-performance liquid chromatography (HPLC), their structures,...
A pyrene-fused phenazinothiadiazole that shows electron mobilities (μe = 0.016 cm(2) V(-1) s(-1)) two orders of magnitude higher than those reported for pyrene-fused pyrazaacenes is described.
Tetrocarcin A (TCA), produced by Micromonospora chalcea NRRL 11289, is a spirotetronate antibiotic with potent antitumor activity and versatile modes of action. In this study, the biosynthetic gene cluster of TCA was cloned and localized to a 108-kb contiguous DNA region. In silico sequence analysis revealed 36 putative genes that constitute this cluster (including 11 for unusual sugar biosynth...
Two fused cyclopentadithiophenebis(dicyanovinylene) derivatives (FCPDT-16 and FCPDT-C24) with a low-lying LUMO energy level (3.88 eV) and a rigid core structurewere successfully synthesized.They have good thermal stability and form highly ordered packing structures both in the bulk solid state and in thin films. The field effect transistors fabricated from a solution of these two compounds show...
background and aim: dichotic listening tests have been used to study right ear advantage (rea). fused dichotic rhymed word test (fdrwt), using rhymed words, is advantageous because of reducing the effect of attention on the test results. development of persian version of the fdrwt, and evaluation of its psychometric properties in normal children were the aims of the present study. methods: thi...
A novel Ag(I)-induced three-component annulation reaction of [60]fullerene with sulfonylhydrazones and nitriles has been developed for the efficient synthesis of diverse disubstituted [60]fullerene-fused dihydropyrroles. The reaction exhibits a broad substrate scope and excellent functional-group tolerance, and also allows for the synthesis of fullerene-bound macromolecules.
