HCC

Tiliroside

Ubiquitination

p62/Keap1/Nrf2

Tiliroside is a potent TBK1 inhibitor and functions as a sensitizer of sorafenib in HCC treatment by targeting TBK1 to induce ferroptosis through decreasing the phosphorylation p62 and the affinity of p62 for Keap1 and promoting Keap1-mediated Nrf2 ubiquitination and degradation

533

HCC

Corosolic acid

Ubiquitination

HERPUD1

CA can increase sensitivity to ferroptosis through inhibiting GSH synthesis via HERPUD1, which reduced the ubiquitination of the GSS-associated E3 ubiquitin ligase MDM2, promoting ubiquitination of GSS, thereby inhibiting GSH synthesis to increase ferroptosis susceptibility

534

HCC

DHA

Ubiquitination

PEBP1

DHA induced ferroptosis by promoting the formation of PEBP1/15-LO and promoting cell membrane lipid peroxidation. DHA promote PEBP1 protein expression through inhibition of its ubiquitination degradation.

535

HCC

Polyphyllin VI

Phosphorylation

STAT3

Polyphyllin VI induces the ferroptosis through inhibiting STAT3 phosphorylation, which inhibits GPX4 expression.

536

HCC

Anisomycin

Phosphorylation

p38MAPK

Anisomycin activates p38MAPK to induce ferritinophagy through the phosphorylation of histone H3 on serine 10 (p-H3S10).

537

NSCLC

Bufotalin

Ubiquitination

GPX4

Bufotalin induces ferroptosis by facilitating the ubiquitination and degradation of GPX4.

538

NSCLC

Sanguinarine

Ubiquitination

GPX4

Sanguinarine triggered ferroptosis through decreasing the protein stability of GPX4 through E3 ligase STUB1-mediated ubiquitination and degradation of endogenous GPX4.

539

NSCLC

Selenite

Methylation

p38MAPK

Selenite induces ferroptosis through activating p38-ATF4-DDIT3 axis in the unfolded protein response. Selenite also altered cellular DNA methylation machinery through downregulating DNMT1 and upregulating TET1, though not as a major mechanism of its activity. Low-dose selenite synergized with osimertinib in EGFR-mutant H1975, and with adagrasib in KRAS-mutant H358, with stronger synergism observed in H1975.

540

BC

Eupaformosanin

Ubiquitination

p53

Eupaformosanin significantly inhibited the viability of triple-negative breast cancer (TNBC) cells through inducing ferroptosis via ubiquitination of mutant p53.

541

BC

DMOCPTL

Ubiquitination

GPX4

DMOCPTL induce ferroptosis through ubiquitination of GPX4.

542

BC

NN3

Ubiquitination

p53/SLC7A11

NN3 triggers ubiquitination and proteasome-mediated degradation of PARP1. NN3 exhibited a unique antitumor mechanism in p53-positive breast cancer cells that effectively promoted ferroptosis by downregulating the SLC7A11 pathway.

543

BC

Ketamine

Acetylation

KAT5

Ketamine induces ferroptosis through inhibiting the expression of GPX4 by attenuating KAT5 on the promoter region of GPX4, repressing the enrichment of histone H3 lysine 27 acetylation (H3K27ac) and RNA polymerase II (RNA pol II)

544

GBM

ALZ003

Ubiquitination

Androgen receptor

ALZ003 induces FBXL2-mediated AR ubiquitination and degradation. ALZ003 significantly inhibited the survival of glioblastomathrough inducing ferroptosis

545

Glioma

Paeoniflorin

Ubiquitination

NEDD4L/STAT3

Paeoniflorin might function as an effective drug for glioma by inducing ferroptosis via upregulation of NEDD4L and mediates the ubiquitination of STAT3 repression of Nrf2, GPX4

546

GBM

Myrislignan

Phosphorylation

NF-κB

Myrislignan inhibited the activation of NF-κB signaling by blocking the phosphorylation of p65 protein and induced ferroptosis through the Slug-SLC7A11 signaling pathway in GBM cells

547

OC

Eriodictyol

Phosphorylation

Nrf2

Eriodictyol induces ferroptosis through downregulating Nrf2 phosphorylation,thereby decreasing protein levels of SLC7A11 and GPX4

550

Thyroid cancers

RSL3

Phosphorylation

mTOR

RSL3 activate ferroptosis through suppressing mTOR signaling pathway triggered autophagy. GPX4 genetic knockdown mirrored RSL3 effect on mTOR pathway suppression.

551

Pancreatic cancer

QD394

Phosphorylation

STAT3

QD394 induces ferroptosis through inhibiting STAT3 phosphorylation, thereby inhibiting GPX4

548

ESCC

Allicin

Phosphorylation

AMPK

Allicin may induce ferritinophagy through increasing AMPK phosphorylation and decreasing mTOR
