It is our working hypothesis that the high rate of the liver and gastric cancers in North and Northeast Thailand is associated with increased daily dietary intake of nitrate, nitrite, and nitrosodimethylamine (NDMA). Samples of fresh and preserved Th

Rising leukemia rates in Thailand: The possible role of benzene and related compounds in cigarette smoke

Autor: Thira Limsila, Anthony P. Polednak, Charles F. Hummel, Eugene J. Mitacek, Klaus D. Brunnemann, Kris Bhothisuwan

Publikováno v: Oncology Reports.

Epidemiological studies suggest that cigarette smoking is associated with an increased risk of leukemia and that benzene and related compounds in cigarette smoke may contribute to this elevated risk. This report presents new findings on selected comp

Enthalpic and entropic determinants for the specificity of alkylation of the histidine-12 residue of ribonuclease A by four bromoacetamido nucleoside affinity labels and bromoacetamide

Autor: Charles F. Hummel, Robert P. Carty, Matthew R. Pincus, Paul W. Brandt-Rauf

Publikováno v: International journal of peptide and protein research. 36(1)

The binding and alkylation rate constants for the reaction of four bromoacetamido pyrimidine nucleosides and bromoacetamide with bovine pancreatic ribonuclease A (RNase A) have been determined as a function of temperature. The four nucleoside derivat

Reaction of Azide Ion with 1-(2,3-Anhydrolyxofuranosyl)Uracil. Isolation of 1-(2-Amino-2-deoxy-β-D-Xylo-Furanosyl)uracil and 1-(3-Amino-3-deoxy-β-D-arabinofuranosyl)uracil

The reaction of the 2′,3′-lyxoepoxide (1) with ammonium azide gives two products; namely, the 3′-arabino azide (2a) and in low yield 2′-xylo azide (3a). After debenzoylation and reduction the resulting mixture of amines was resolved by chroma
