Dinucleotide cap analogs containing tetraphosphate bridge modified by replacing one of the bridging oxygen atoms with methylene group were synthesized. The analogs have been examined for their stability towards enzymatic hydrolysis by human DcpS and binding affinity for eIF4E. Their inhibitory properties in rabbit reticulocyte lysate (RRL) translational system were studied.

D004164 Diphosphonates Organic compounds which contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism. They inhibit ectopic calcification and slow down bone resorption and bone turnover. Technetium complexes of diphosphonates have been used successfully as bone scanning agents. Bisphosphonate,Bisphosphonates
D004722 Endoribonucleases A family of enzymes that catalyze the endonucleolytic cleavage of RNA. It includes EC 3.1.26.-, EC 3.1.27.-, EC 3.1.30.-, and EC 3.1.31.-. Endoribonuclease
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
