Abstract:
DedA membrane proteins promote the formation of double-membrane vesicles serving as replication platforms for RNA viruses, including SARS-CoV-2. Inspired by the only known inhibitor, halicyclamine A, we developed a concise biomimetic synthesis of halicyclamine-inspired macrocycles, identifying bis-macrocycles that suppress SARS-CoV-2 replication, while exhibiting DedA-associated activity in a bacterial overexpression assay.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
