Synthesis of some biologically active 2,4’-bipyridine-5-carbonitriles carrying the 4-hydroxyphenylthio moiety [PDF]
Journal of the Serbian Chemical Society, 2009 A series of new 4-aryl-2’-[(4-hydroxyphenyl)thio]-6oxo-1,6-dihydro-2,4’-bipyridine-5-carbonitriles (3a–k) and 6-amino-4aryl-2’-[(4-hydroxyphenyl)thio]-2,4’-bipyridine-5-carbonitriles (4a–h) were synthesized from 4-hydroxythiophenol (1). The reaction of 4-

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.
