RA375, an inhibitor of RPN13 (26S proteasome regulatory subunit), enhances UPR signaling, ROS production, and apoptosis. Demonstrating ten times the efficacy against cancer lines compared to RA190, RA375 owes its increased activity to nitro ring substituents and the inclusion of a chloroacetamide warhead.

MG-132 (Z-Leu-Leu-Leu-al) is a 26S proteasome inhibitor (IC50=100 nM) that is cell-permeable and reversible. MG-132 acts as an autophagy activator and also induces apoptosis.

DL-Borneol ((endo)-Borneol) is a small molecule extracted from traditional Chinese medicine (TCM). It is an orally bioadjuvant that improves drug delivery to the brain and is commonly used as an adjuvant ingredient in TCM for the treatment of cardio-cerebral vascular diseases.

Alloxan Monohydrate is a diabetogenic agent that acts as a proteasome inhibitor and induces diabetes in experimental animals by damaging the insulin-secreting β-cells in the pancreas. It is commonly used to establish diabetes models.

GSK3494245 is a Leishmania donovani inhibitor that suppresses trypsin-like activity catalyzed by the β5 subunit of L. donovani proteasome, applicable for visceral leishmaniasis (VL) studies.

B-AP15 (NSC-687852)(NSC-687852) is a selective inhibitor of the deubiquitinating enzymes Usp14 and UCHL5 of the 26S proteasome. It blocks the deubiquitinating activity of the 26S proteasome.

Boc-LRR-AMC is a fluorogenic substrate for the trypsin-like activity of the 26S proteasome or 20S proteolytic core. Upon enzymatic cleavage by the 26S proteasome or 20S proteolytic core, amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify 26S proteasome or 20S proteolytic core trypsin-like activity. AMC displays excitation/emission maxima of 340-360/440-460 nm, respectively.

Boc-LRR-AMC TFA is a fluorescent protease substrate used to detect the trypsin-like activity of the 26S proteasome or 20S proteasome core.

Z-LLE-AMC (Z-Leu-Leu-Glu-AMC) is a fluorogenic substrate used to detect caspase-like post-glutamate peptide hydrolase activity in the 26S proteasome or 20S proteolytic core. Caspase-like activity can be quantified by fluorescent detection of free AMC (7-amino-4-methylcoumarin), which has an excitation wavelength of 340–360 nm and an emission wavelength of 440–460 nm. Z-LLE-AMC is typically used in cell lysates after experimental treatment. Additionally, Z-LLE-AMC can also be used in Parkinson's disease research.

Z-LLL-AMC is a fluorogenic substrate for the chymotrypsin-like activity of the 26S proteasome or 20S proteolytic core. Chymotrypsin-like activity can be quantified by fluorescent detection of free AMC (also known as 7-amino-4-methylcoumarin), which is excited at 340-360 nm and emits at 440-460 nm. Z-LLL-AMC is typically used in cell lysates after experimental treatment.

DDO-7263 is a 1,2,4-Oxadiazole derivative that upregulates Nrf2 through binding to Rpn6 to block the assembly of 26S proteasome and the subsequent degradation of ubiquitinated Nrf2. DDO-7263 is a potent Nrf2 activator that activates the Nrf2-ARE signaling pathway and exerts anti-inflammatory activity [1].

TM-1 is an effective 26S proteasome inhibitor and autophagy inducer. It increases LC3-II levels to suppress tumor growth via dual degradation pathway modulation in cancer research.

Ac-Nle-Pro-Nle-Asp-AMC is a specific substrate for the 26S proteasome, utilized for analyzing the proteasome's caspase-like activity [1] [2] [3].

WBC100 (14-D-Valine-TPL) is a potent, selective, orally active c-Myc glue degrader targeting the ubiquitin E3 ligase CHIP-mediated 26S proteasome pathway, primarily used in research for c-Myc overexpressing tumors [1].

JMV7048 is an effective PROTAC degrader targeting the PXR (Pregnane X Receptor), with a DC50 of 379 nM. It induces the polyubiquitination and degradation of PXR protein by recruiting the E3 CRBN ubiquitin ligase and the 26S proteasome. This degradation of PXR significantly enhances the chemosensitivity of colorectal cancer stem cells, substantially delaying cancer recurrence in vivo. The composition of JMV7048 includes the PXR agonist JMV6944, a linker, and Thalidomide 5-fluoride.

Ub4ix, a DUB/26S proteasome inhibitor, safeguards K48-linked Ub chains against cleavage by deubiquitinating enzymes (DUBs) and inhibits the proteasomal degradation of Ub-tagged proteins. Additionally, it diminishes the viability of Hela cells and triggers apoptosis, exhibiting an IC 50 value of 1.6 μM.

Ac-RLR-AMC (Ac-Arg-Leu-Arg-AMC) TFA serves as a fluorescent substrate for the 26S proteasome (Ex/Em: 380/440-460 nm). Upon enzymatic cleavage, AMC is released, and its fluorescence allows for the quantification of the trypsin-like activity of the 26S proteasome.
