The phenanthridinium chromophores 5-ethyl-6-phenylphenanthridinium (1), 5-ethyl-6-methylphenanthridinium (2), 3,8-diamino-5-ethyl-6-methylphenanthridinium (3), and 3,8-diamino-5-ethyl-6-(4-N,N-diethylaminophenyl)phenanthridinium (4) were characterized by their optical and redox properties. All dyes were applied in titration experiments with a random-sequence 17mer DNA duplex and their binding a...

Reaction of 3,4,5,6-tetrahydro-2-pyrimidinethiol, prepared by cyclocondensation reaction of 1,3-diamino propane 1 and carbon disulfide, with ethyl chloroacetate and substituted aromatic aldehydes in the presence of sodium acetate and acetic acid gave 2-[(Z)-1-(aryl)]-6,7-dihydro-2H-isothiazolo[2,3-a]pyrimidine-3(5H)-one derivatives 3(a-j) in good yields. 1H-NMR spectroscopy, and elemental analy...

Lysinuric protein intolerance (LPI) is a rare recessively inherited disease in which one of the fundamental physiological defects is in the mechanism by which diamino acids are transported by the kidney. The purpose of the present studies was to examine that mechanism in four controls and seven patients with LPI. Two types of studies were conducted. In the first set, the renal handling of l-arg...

In the title compound, C(9)H(8)Cl(2)N(5) (+)·H(2)PO(4) (-)·C(9)H(11)NO [systematic name: 3,5-diamino-6-(2,3-dichloro-phen-yl)-1,2,4-triazin-2-ium dihydrogen phosphate-4-(dimethyl-amino)-benz-alde-hyde (1/1)], inter-molecular N-H⋯O and O-H⋯O hydrogen bonds produce R(2) (2)(8) and R(3) (2)(8) rings, generating a layer. Inter-molecular N-H⋯N inter-actions also occur. The dihedral angle between the...

Riboflavin, the biosynthetic precursor of the 5,6-dimethylbenzimidazole moiety of vitamin B12, is transformed non-enzymatically into 5,6-dimethylbenzimidazole in small yield on treatment with 1 N or 5 N NaOH at 100 degrees C. Besides 5,6-dimethylbenzimidazole 1,2-diamino-4,5-dimethylbenzene, 1,2-dihydro-6,7-dimethyl-2-keto-1-D-ribityl-3-quinoxaline carboxylic acid and N-1-D-ribitylamino-2-amino...
