TL;DR
Researchers developed a compact DNA-encoded platform molecule to enhance drug discovery by expanding chemical diversity and targeting enzymes and GPCRs.
Contribution
A new compact diazide platform molecule was designed to improve small-molecule drug discovery through enhanced chemical diversity and chemoselective transformations.
Findings
A compact D-DAP based on 3-azido-5-(azidomethyl)benzoic acid was synthesized for drug discovery.
Two warhead construction strategies were established using the diazide platform's chemoselective reactivity.
Virtual DELs generated from the platform show unique structural diversity and drug-like properties.
Abstract
Expanding the chemical diversity of DNA–encoded libraries (DELs) is crucial for identifying binders to emerging drug targets using DEL technology. In the present study, as part of our ongoing efforts to develop on–DNA diazide platforms (D–DAPs)—platform molecules possessing both aromatic and aliphatic azide groups on a single core reactive scaffold—we designed and synthesized a new compact diazide platform, designated as a compact D–DAP (C–D–DAP). This molecule is based on a low–molecular–weight reactive scaffold, 3–azido–5–(azidomethyl)benzoic acid, to facilitate small–molecule drug discovery targeting enzymes and G protein–coupled receptors (GPCRs). Furthermore, we established two distinct stepwise warhead construction strategies that exploit the chemoselective transformations of the azide groups in the C–D–DAP, which exhibit different reactivities. In addition, four virtual DELs were…
