Mutagens present in crude samples such as heated glucose can be detected or identified by means of the adducts formed upon reaction with a fluorescent guanosine derivative (FG) or isopropylideneguanosine (IPG). After the reaction of IPG with heated glucose, two
The synthesis and biological evaluation of a new cap analog, which is modified at the C2' and C3' positions of N(7)-methylguanosine is reported. The new cap analog, P(1)-2',3'-isopropylidene, 7-methylguanosine-5'P(3)-guanosine-5'triphosphate was assayed with respect to its effects on efficiency of incorporation
A number of synthetic methods for the preparation of the 2-O-(alpha-methoxyethyl) derivatives of the 5-diphosphates of adenosine, cytidine, guanosine, and uridine have been studied in order to provide nucleotide substrates that can be applied to the synthesis of specific oligoribonucleotides

Heated glucose is mutagenic to Salmonella typhimurium TA 100 in the absence of S-9 mix. For identifying unknown mutagens in heated glucose (dry solid, 200 degrees C, 20 min), reaction with isopropylideneguanosine (IPG) was followed by isolation and characterization of
