RESUMO
The PROTAC (PROteolysis TArgeting Chimera) technology is a method of targeting intracellular proteins previously considered undruggable. This technology utilizes the ubiquitin-proteasome system in cells to specifically degrade target proteins, thereby offering significant advantages over conventional small-molecule inhibitors of the enzymatic function. Preclinical and preliminary clinical trials of PROTAC-based compounds (degraders) are presented. The review considers the general principles of the design of degraders. Advances and challenges of the PROTAC technology are discussed.
RESUMO
5-(3-Perylenylethynyl)-2'-deoxyuridine was prepared by cross-linking 5-iodo-2'-deoxyuridine derivatives with 3-ethynylperylene followed by deprotection. 5-(1-Perylenylethynyl)-, 5-(3-perylenylethynyl)-, and 5-[4-(2-benzoxazolyl)phenylethynyl]-2'-deoxyuridine were found to inhibit in Vero cells the replication of type 1 herpes simplex virus and its drug-resistant strains.
