Derivatives of bovine growth hormone, containing monoaminotyrosyl residues in positions 35, 42 and 174, were treated at pH 3.6 with a bifunctional reagent, 1,5-difluoro-2,4-dinitrobenzene. Under these conditions aminotyrosyl groups reacted. On changing the pH to 9.3, the second fluorine atom

Intact chloroplasts were isolated from Euglena gracilis variety bacillaris, aliquots were exposed to several different chemical cross-linking reagents. The reagents penetrated the triple membrane of Euglena chloroplasts. This was shown by gradient acrylamide gel electrophoresis under denaturing conditions. The activity

A practical and efficient new parallel method has been developed for the synthesis of 3-substituted indolin-2-ones with a large variety of substituents at the 5- and 6-positions using 1,5-difluoro-2,4-dinitrobenzene. This 3,5,6-substituted indolin-2-one skeleton possesses three points of diversification and, thus

This paper reports a versatile, good-yielding, solution-phase method that is a substituent diversity-directed synthesis of 1H-indoles (6-13, 17-20) and 1-hydroxyindoles (14, 15) starting from commercially available 1,5-difluoro-2,4-dinitrobenzene. The synthetic products possessed the maximum six diversity points.

This paper describes our recent efforts to synthesize novel compound scaffolds integrating 2-quinoxalinol with privileged structures of 1,3-dihydro-benzoimidazol-2-one, 1,3-dihydro-benzoimidazole-2-thione, 3-hydroxy-1H-quinoxalin-2-one, 2H-benzo[1,4]oxazin-3-ol, 2H-benzo[1,4]thiazin-3-ol, and 1,3,4,5-tetrahydro-benzo[1,4]diazepin-2-one, respectively. Eight novel benzofused tricycles and their substituent diversity points were developed. These include pyrazino[2,3-g]quinoxaline-2,8-diol (I)
