Interferons (IFNs) have established activities as antivirals and inhibitors of viral and transplantable tumors. To establish whether IFNs or their inducers can affect induction of carcinogenesis in vivo, the bladder-specific carcinogen N-[4-(5-nitro-2-furyl)-2-thiazolyl]formamide (FANFT) was administered in the diet at 0.11 or 0.13% (w/w) to female C3H/He mice beginning at 7 weeks of age. Mice ...
A microscale chemistry improvement engine: a pre-dosed microscale high-throughput experimentation additives platform enables rapid, serendipitous reaction improvement. This platform allowed one chemist to set up 475 experiments and analyze the results using MISER chromatography in a single day, thus resulting in two high-quality catalytic systems for the construction of the title compound 1. Su...
Block-localized wave function (BLW) method, which is a variant of the ab initio valence bond (VB) theory, was employed to explore the nature of resonance-assisted hydrogen bonds (RAHBs) and to investigate the mechanism of synergistic interplay between pi delocalization and hydrogen-bonding interactions. We examined the dimers of formic acid, formamide, 4-pyrimidinone, 2-pyridinone, 2-hydroxpyri...
Evidence for an error-free DNA damage tolerance process in eukaryotes (also called postreplication repair) has existed for more than two decades, but its underlying mechanism, although known to be different from that in prokaryotes, has remained elusive. We have investigated this mechanism in Saccharomyces cerevisiae, in which it is the major component of the RAD6/RAD18 pathway, by transforming...
