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.

Anti-cancerOxidative StressFerroptosisOthers

Anti-cancer

CCW16 (5 μM; 6 h) in HeLa Flp-In T-REx cells with inducible RNF4 does not degrade RNF4 but induces upregulation of HMOX1, heat shock protein 70 family members, and NRF2, consistent with an oxidative stress response^[1].
CCW16 (5 μM; 6 h)-induced upregulation of HMOX1 and NRF2 occurs in both wild-type and RNF4 knockout HeLa cells, confirming that the oxidative stress response is RNF4-independent^[1].
CCW16 (6 h) alone does not degrade RNF4 protein in HepG2 cells^[3].

Oxidative Stress

CCW16 (10 μM; 2 h + overnight) in HeLa cell lysates reacts non-selectively with approximately 1200 proteins, including the catalytic cysteines of peroxiredoxins PRDX1, PRDX2, and PRDX6, identifying CCW16 as a non-selective covalent ligand that disrupts redox homeostasis^[1].

Ferroptosis

CCW16 (2.5 μM; 2.5 h) induces robust lipid peroxidation in OCI-AML2 cells within 2.5 h, a key hallmark of ferroptosis^[1].
CCW16 (1 μM; 6 h) reduces viability of OCI-AML2 cells after 6 h via induction of ferroptosis, which is rescued by the ferroptosis inhibitor Ferrostatin-1 (HY-100579)^[1].

Ferroptosis

Oxidative Stress

CCW16 (5 μM; 6 h)-induced ferroptotic cell death in HT-1080 cells is fully rescued by GPX4 overexpression, demonstrating that CCW16 exerts its ferroptotic effect through a GPX4-sensitive pathway^[1].

Others

CCW16 (10 µM; 2 h at 4 °C plus overnight at 4 °C) covalently modifies a broad spectrum of over 2000 proteins, including the catalytic cysteines of peroxiredoxins PRDX1, PRDX2, and PRDX6, indicating low target selectivity^[2].
CCW16 binds covalently to RNF4 at C132 or C135 with a low micromolar affinity of 1.8 μM but does not inhibit RNF4 enzymatic activity^[3].
CCW 16 covalently inhibits RNF4 with an IC₅₀ of 1.8 μM by modifying zinc-coordinating cysteines C132 and C135 in the RING domain^[4].

Oxidative Stress

Ferroptosis

CCW16 (5 µM; 6 h) does not degrade RNF4 but induces a strong RNF4-independent oxidative stress response marked by upregulation of HMOX1, NRF2, and heat shock proteins, with enrichment of the ferroptosis pathway^[2].
CCW16 (2.5 µM; 2.5 h) induces robust lipid peroxidation in OCI-AML2 cells^[2].

Western Blot Analysis^[1]

Cell Line:

Wild-type and RNF4 knockout HeLa cells
Concentration:

5 μM
Incubation Time:

6 h
Result:

Induced upregulation of HMOX1 in both wild-type and RNF4 knockout HeLa cells, demonstrating the stress response is independent of RNF4.
Increased NRF2 protein levels in both wild-type and RNF4 knockout HeLa cells, consistent with activation of the NRF2-mediated oxidative stress response pathway.

Cell Viability Assay^[1]

Cell Line:

OCI-AML2 acute myeloid leukemia cells
Concentration:

1 μM
Incubation Time:

6 h; 1 h (ferrostatin-1 pretreatment)
Result:

Caused a significant reduction in OCI-AML2 cell viability.
Induced cell death that was substantially rescued by pretreatment with the ferroptosis inhibitor ferrostatin-1, confirming cell death occurs via ferroptosis.

Cell Viability Assay^[1]

Cell Line:

HT-1080 fibrosarcoma cells
Concentration:

5 μM
Incubation Time:

6 h; 1 h (ferrostatin-1 pretreatment)
Result:

Induced cell death in parental HT-1080 cells carrying an empty vector.
Did not induce cell death in cells stably overexpressing GPX4, which were fully protected, indicating ferroptotic activity is linked to GPX4 function.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
