On March 31, 2017, Ostakhov, S. S.; Sultanbaev, M. V.; Ovchinnikov, M. Yu.; Kayumov, R. R.; Khursan, S. L. published an article.COA of Formula: C5H6N2O2 The title of the article was Spectral-luminescence and quantum-chemical study of the anionic forms of 5-fluorouracil. And the article contained the following:
A spectral-luminescence study of neutral (pH 7) and alk. (pH 11 and 14) aqueous solutions of the anticancer drugs 5-fluorouracil (FU) and tegafur has been performed. The fluorescence spectra of the N3- and N1-centered anions of 5-fluorouracil, its dianion, and the tegafur monoanion with emission maxima at wavelengths (λem) of 358, 372, 366, and 358 nm and photoluminescence quantum yields (φ) of 11.2 x 10-4, 35.1 x 10-4, 26.5 x 10-4, and 8.6 x 10-4, resp., have been recorded for the first time. The fluorescence characteristics of the FU anionic forms have been related to the magnetic shielding constant as one of the criteria of aromaticity. The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).COA of Formula: C5H6N2O2
