ARD-69	PROTACs Androgen Receptor	Cancer
ARD-69 is a PROTAC degrader based on the E3 ubiquitin ligase VHL and targeting the androgen receptor, which can induce androgen receptor (AR) protein degradation in AR-positive prostate cancer cells. ARD-69 inhibits AR-regulated gene expression, binds to the AR ligand binding domain at one end and binds to VHL at the other end, prompting AR to be recruited to the E3 ubiquitin ligase complex, triggering proteasome degradation, thereby inhibiting AR signaling pathways and downstream gene expression (such as *PSA, TMPRSS2). ARD-69 can be used to study the treatment of castration-resistant prostate cancer (mCRPC) . ARD-69 is composed of a target protein* ligand (pink part) AR antagonist 14 (HY-172624), a PROTAC linker (black part) tert-Butyl 4-ethynyl-[1,4'-bipiperidine]-1'-carboxylate (HY-W442074), and a VHL-type E3 ubiquitinase ligand (blue part) VH 101, acid (HY-47070); among them, the VHL ligand and the linker can form a conjugate VH 101-amide-piperidine-Pip-alkyne (HY-172625).

Lead-like Covalent Screening Library	1,272 compounds
Small molecule covalent inhibitors, or irreversible inhibitors, are a type of inhibitors that exert their biological functions by irreversibly binding to target through covalent bonds. Compared with non-covalent inhibitors, covalent inhibitors have obvious advantages in bioactivity, such that covalent warheads can target rare residues of a particular target protein, thus leading to the development of highly selective inhibitors and achieving a more complete and continued target occupancy in living systems. In recent years, the distinct strengths of covalent inhibitors in overcoming drug resistance had been recognized. However, toxicity can be a real challenge related to this class of therapeutics due to their potential for off-target reactivity and has led to these drugs being disfavored as a drug class. The drug design and optimization of covalent inhibitors has become a hot spot in drug discovery. MCE Lead-like Covalent Screening Library offers a valuable resource of 1,049 lead-like compounds with commonly used covalent warheads. These warheads, such as acrylamide, activated terminal alkyne, acyloxymethyl ketone, and boronic acid, are capable of reacting with specific amino acid residues, including cysteine, lysine, serine, and histidine. The inclusion of these reactive warheads in the library allows researchers to explore the potential of covalent inhibition, a powerful approach in drug discovery.
