ubiquitylation

Vepdegestrant (ARV-471) is an estrogen receptor (ER) α PROTAC molecule that degrades ER in ER-positive breast cancer cell lines with a DC50 of approximately 1 nM. It can reduce the expression of classically regulated ER target genes and inhibit the growth of ER-dependent cell lines (including those expressing ESR1 variants, such as Y537S and D538G) by degrading ER.

Apcin is a potent and competitive inhibitor of anaphase-promoting complex/cyclosome (APC/C(Cdc20)) E3 ligase activity. Apcin competitively inhibits APC/C-dependent ubiquitylation by binding to Cdc20 and preventing substrate recognition. It acts by blockin

HM90822 is a novel synthetic apoptotic protein (IAP) antagonist that induces apoptosis in human pancreatic cancer cells through proteasome-dependent degradation of IAPs containing the BIR2/3 structural domain.HM90822 inhibits the expression of XIAP and cIAP1/2 proteins in HM822-sensitive Panc-1 and BxPC-3 cells, induces ubiquitylation of IAPs and promotes induces IAP ubiquitination and promotes proteasome-dependent IAP degradation.

LS-102 is a selective inhibitor of the E3 ligase synoviolin (Syvn1), an astragaloside IV derivative, which attenuates myocardial ischemia/reperfusion injury by inhibiting mitochondrial fission.LS-102 inhibits Syvn1 auto-ubiquitylation, which ameliorates amyloidazole-induced slowing of the heart rate, and is useful for studying cardiovascular diseases.

GS143 is a selective IκBα ubiquitination inhibitor with an IC50 of 5.2 μM for SCFβTrCP1-mediated IκBα ubiquitylation. It suppresses NF-κB activation and transcription of target genes without inhibiting proteasome activity. GS143 has anti-asthm[atic] properties.

PRT4165 (NSC600157) is a potent PRC1-mediated H2A ubiquitylation inhibitor.

FT3967385 is a newly developed compound that functions as a USP30 inhibitor, emulating the genetic deficiency of USP30. This inhibition serves as a catalyst for the amplification of mitochondrial ubiquitylation through the PINK1-PARKIN pathway.

FT385 is a novel USP30 inhibitor, recapitulating genetic loss of USP30 and setting the trigger for PINK1-PARKIN amplification of mitochondrial ubiquitylation.

NRX-0492 is an orally administered compound that efficiently degrades Bruton's tyrosine kinase (BTK) by catalyzing its ubiquitylation and subsequent proteasomal degradation, achieving half-maximal degradation concentrations (DC50) of ≤0.2 nM and 90% degradation concentrations (DC90) of ≤0.5 nM. Additionally, NRX-0492 suppresses B-cell receptor (BCR) signaling, transcriptional activities, and chemokine production by linking a noncovalent BTK-binding domain to Cereblon, an adaptor protein within the E3 ubiquitin ligase complex [1].
