《Synthesis of Four Optical Isomers of Antiviral Agent NK0209 and Determination of Their Configurations and Activities against a Plant Virus》 was written by Wang, Haiqi; Song, Hongjian. Safety of H-Trp-OMe.HCl And the article was included in Journal of Agricultural and Food Chemistry in 2020. The article conveys some information:
Previously, we reported for the first time that harmala alkaloids harmine and tetrahydroharmine exhibit activity against plant viruses, and we developed an analog, designated NK0209, that efficiently prevents and controls plant virus diseases. Here, to investigate the influence of the spatial configuration of NK0209 on its antiviral activities, we synthesized its four optical isomers, determined their configurations, and evaluated their activities against tobacco mosaic virus. All four isomers were significantly more active than ningnanmycin, which is one of the most successful com. antiviral agents, with in vivo inactivation, cure, and protection rates of 57.3±1.9%, 54.2±3.3%, 55.0±4.1% at 500μg/mL. Furthermore, anal. of structure-activity relationships demonstrated for the first time that the spatial conformation of NK0209 is an important determinant of its antiviral activity, and our results provide information about the possible optimum configuration for interaction of this mol. with its target protein. In the experiment, the researchers used many compounds, for example, H-Trp-OMe.HCl(cas: 7524-52-9Safety of H-Trp-OMe.HCl)
H-Trp-OMe.HCl(cas:7524-52-9) is one of amino acid derivatives. Amino acid derivatives represent an important category of skin penetration promoters. These compounds possess hydrophobic chains attached to an amino acid headgroup via a biodegradable ester bond. Due to the amphiphilic nature of these derivatives, it is possible for them to enter into the SC lipid barrier and significantly disorganize skin membrane lipids.Safety of H-Trp-OMe.HCl
