4H-furo[3,2-b]pyrrole

Solid Phase Extraction Method for Patulin in Apple Juice and Unfiltered Apple Juice

Patulin, 4-hydroxy-4H-furo[3,2c]pyran-2(6H)-one (Fig. 1 ), is alactone containing secondary metabolite of several species of Penicillium and Aspergillus. P. expansum is the most common mold producing patulin in apples, pears, and cherries

Site-Specific Incorporation of Extra Components into RNA by Transcription Using Unnatural Base Pair Systems

several unnatural base pairs that function in PCR and in vitro transcription. Among them, a hydrophobic, unnatural base pair between 7-(2-thienyl)-imidazo[4,5-b]pyridine (denoted by Ds ) and pyrrole-2-carbaldehyde (denoted by Pa ) exhibits high fidelity in PCR and T

General Laboratory Methods for Tetrapyrroles

-pyrrole positions, at the four meso [5,10,15,20] carbon atoms, and N-alkyl groups can be added to the four central nitrogen atoms. Since its synthesis in 1972, over 8000 literature references have appeared on 5,10,15, 20-tetrakis(N-methyl-4-pyridyl
