New research progress on 4254-15-3 in 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. COA of Formula: C3H8O2, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 4254-15-3
A number of methyl derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and tested in vitro for anti-herpes and anti- human immunodeficiency virus (HIV) activity. Among these analogues, (R)-2′- methyl-PMEG [(R)-3] and 2′,2′-dimethyl-PMEG (7) demonstrated potent anti-HIV activity in the XTT-assay with EC50 values of 1.0 and 2.6 muM, respectively. The corresponding (S)-2′-methyl-PMEG [(S)-3] was found to be less potent against HIV. In addition, the (R) and (S) enantiomers of 9-[3- hydroxy-2-(phosphonomethoxy)propyl]guanine (HPMPG, 8) were prepared for comparison of biological activity, and shown to be active and equipotent against herpesviruses, but inactive against HIV.
