GtoPdb Ligand ID: 13110

Synonyms: compound 9 [PMID: 38194973] | WD-6305

Comment: WD6305 is a heterobifunctional degrader (PROTAC) that targets the RNA methyltransferase METTL3 [1]. It is intended to promote proteasomal degradation of the METTL3-METTL14 methyltransferase complex as an anti-leukemic strategy. The PROTAC engages the Hippel-Lindau (VHL) E3 ligase, and METTL3 is targeted by the small molecule inhibitor UZH2. WD6305 inhibits N⁶-methyladenosine (m⁶A) methylation of RNA, and has the effect of reducing proliferation of AML cells. It more efficiently reduces proliferation of AML cells than blocking METTL3 catalytic activity with UZH2.
