We report that N(2),N(6)-bis(4-nitrophenyl)pyridine-2,6-dicarboxamide, which is related to known isophthalic acid dianilides, transports Cl(-) ions through phospholipid bilayer membranes and shows clear evidence of channel activity.

In this study, the bioactive compounds present in the ethyl acetate extracts of two different Streptomyces strains isolated from vermicast (earthworm fecal pellets) were investigated using Gas Chromatography and Mass Spectrometry (GC-MS). GC-MS analysis showed the presence of 12 and 9 bioactive compounds in AS1 and AS3 respectively. GC-MS analysis of AS1extract revealed the presence of major bi...

The reactions of [(thf)2TiCl4] with sodiated 2,2’-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-1,1’-biphenyl (1 a) and 2,2’-bis[2-hydroxy-3,5-di(tert-butyl)benzylideneamino]-4,4’-dimethyl-1,1’-biphenyl b) yield the corresponding Ti complexes 2 a b. Similarly, 1 reacts [(thf)2ZrCl4] to Zr derivative 3. For a, mixture cis-β trans isomers were observed in solution whereas congener exclusively...
