연구분야:
CCW16 is a non-selective cysteine-reactive covalent ligand and an RNF4 E3 ubiquitin ligase recruiter with an IC50 of 1.8 μM against human RNF4[. CCW16 covalently modifies accessible cysteine residues on RNF4, PRDX1, PRDX2, and PRDX6, attenuating the peroxide-scavenging activity of peroxiredoxins. CCW16 induces oxidative stress through upregulation of HMOX1 and NRF2, and triggers ferroptosis via lipid peroxidation and ROS signaling pathways in an RNF4-independent manner. CCW16 serves as an RNF4-recruiting moiety; it does not induce RNF4 degradation when used alone and can be used to synthesize protein degraders, such as the PROTAC compound CCW 28-3 (HY-156774). CCW16 can be used for research on acute myeloid leukemia and hepatocellular carcinoma .

T-sCPY-s500R-H is a NADPH-based FRET ratiometric biosensor probe. T-sCPY-s500R-H forms a 1:1 FRET pair upon binding to the eDHFR-HaloTag fusion protein through conjugation of the donor s500R (green fluorescence) and the acceptor sCPY (red fluorescence) with the HaloTag ligand and the eDHFR ligand (TMP), respectively; NADPH binding to eDHFR induces a conformational change that converts sCPY from a colorless spirolactam form to a red fluorescent form, enabling quantification of NADPH levels through the ratio of red/green fluorescence intensity (Ex = 488 or 490 nm; green channel Em = 500-580 nm; red channel Em = 600-700 nm). T-sCPY-s500R-H is applicable to research in fields such as cell metabolism studies, oxidative stress and NADPH homeostasis analysis, tumor metabolism, and NADPH-modulating drug screening .

Oxygen homeostasis regulation is the most fundamental cellular process for adjusting physiological oxygen variations, and its irregularity leads to various human diseases, including cancer. Hypoxia is closely associated with cancer development, and hypoxia/oxygen-sensing signaling plays critical roles in the modulation of cancer progression.
Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that functions as a master regulator of oxygen homeostasis. A variety of HF-1 target genes have been identified thus far which encode proteins that play key roles in critical developmental and physiological processes including angiogenesis/vascular remodeling, erythropoiesis, glucose transport, glycolysis, iron transport, and cell proliferation/survival.
HIF-1 is a heterodimeric transcription factor consisting of a constitutively expressed β-subunit and an oxygen-regulated α-subunit. The unique feature of HIF-1 is the regulation of HIF-1α expression and activity based upon the cellular O2 concentration. Under normoxic conditions, hydroxylation of HIF-1α on these different proline residues is essential for HIF proteolytic degradation by promoting interaction with the von Hippel-Lindau tumor-suppressor protein (pVHL) through hydrogen bonding to the hydroxyproline-binding pocket in the pVHL β-domain. As oxygen levels decrease, hydroxylation of HIF decreases; HIF-1α then no longer binds pVHL, and becomes stabilized, allowing more of the protein to translocate to the cell’s nucleus, where it acts as a transcription factor, upregulating (often within minutes) the production of proteins that stimulate blood perfusion in tissues and thus tissue oxygenation.
MCE offers a unique collection of 4,317 oxygen sensing related compounds targeting HIF/HIF Prolyl-Hydroxylase, MAPK/ERK, PI3K/AKT signaling pathways, etc. MCE Oxygen Sensing Compound Library is a useful tool to study hypoxia, oxidative stress and discover new anti-cancer drugs.

Synonyms: Z-VAD(OH)-FMK (Standard)
Z-VAD-FMK (Standard) is the analytical standard of Z-VAD-FMK (HY-16658B). This product is intended for research and analytical applications. Z-VAD-FMK is a pan-caspase inhibitor and also an ICE-like protease inhibitor, which inhibits apoptosis by preventing the processing of CPP32 to its active form. Z-VAD-FMK sensitivity varies primarily due to differential expression of receptor-interacting protein 1 (RIP1). Z-VAD-FMK limits the cryopreservation-induced apoptosis by reducing caspase-3 activity of in vitro produced bovine embryos. Z-VAD-FMK is immunosuppressive in vitro and inhibits T cell proliferation without blocKing the processing of caspase-8 and caspase-3. Z-VAD-FMK leads to a decrease in intracellular glutathione (GSH) with a concomitant increase in reactive oxygen species (ROS) levels in activated T cells. Z-VAD-FMK is due to oxidative stress via the depletion of GSH. Z-VAD-FMK can be used for the study of acute pancreatitis .
