An update on the development and trials of synthetic peptide vaccines is reviewed. The review considers the successful examples of specific protection as a result of immunization with synthetic peptides using various protocols. The importance of conformation for the immunogenicity of the peptide is pointed out. An alternative strategy of the protection of the organism against the infection using synthetic peptides is suggested.
A manufacturable technology for the production of an antiviral composition containing phosphonoacetic acid, involing РН-alkylation of dimethyl phosphite with methyl chloroacetate under phasetransfer conditions and subsequent in situ hydrolysis of the intermediate product, was developed. The composition showed expressed antiviral effect against herpesviral infections caused by herpes simplex virus 1 and 2 and cytomegalovirus. The composition in the effective concentration range was found to exhibit no cytotoxic effect on VERO green monkey kidney and М-19 human diploid cell cultures. The resulting data suggest potential uses of the composition as an antiviral agent in practical medicine and as an antiviral additive to synthetic detergents for sanitation in health care and food production facilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
