Synthesis and antiviral activity of lycorine derivatives was written by Yang, Ya-Jun;Liu, Jiang-Ning;Pan, Xian-Dao. And the article was included in Journal of Asian Natural Products Research in 2020.COA of Formula: C9H10O4 This article mentions the following:
There are no effective antiviral drugs to treat hand, foot, and mouth disease. In this study, a series of lycorine derivatives were synthesized and evaluated against enterovirus 71 and coxsackievirus A16 in vitro. Derivatives with the phenoxyacyl group at the C-1 position showed higher efficacy and lower toxicity than lycorine. In addition, derivative enhanced the survival rate to 40% in the mouse model of the lethal EV71 infection. In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4COA of Formula: C9H10O4).
2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.COA of Formula: C9H10O4
