Table 2 Therapeutic targets for RCD in osteoporosis and periodontitis.

From: Emerging regulated cell death mechanisms in bone remodeling: decoding ferroptosis, cuproptosis, disulfidptosis, and PANoptosis as therapeutic targets for skeletal disorders

Drugs

Mechanism for the treatment of osteoporosis

RCD

Drugs

Mechanism for the treatment of periodontitis

COX19, MAP-2K2, FDX1

Strongly correlated with immune cell infiltration and associated with osteoporosis prognosis.

Cuproptosis

ME-344, NV-128, RILUZOLE

Demonstrated good affinity for target genes(SLC7A11, SLC3A-2, RPN1, NCKAP1, LRPPRC, NDUFS1).

TXNRD1 inhibitors

Increases bone cystine content, reduces osteoclast numbers, and mitigates bone loss.

disulfidptosis

Target molecules

MLKL, DCN, IL1B, and IL18. Reduce inflammation and tissue destruction.

PGRMC2

Modulates the differentiation of monocytes into macrophages and influences BM-MSC behavior.

disulfidptosis

ZBP1 Inhibitor

Reduces inflammatory cytokine secretion and cell death.

BMDMs

Essential cells in macrophage activation and osteolysis.

PANoptosis

Caspase-1 Inhibitor

Alleviate inflammation and tissue damage.

Apelin-13

Regulates autophagy, apoptosis, and inflammation, exerting multifaceted protective effects on bone.

PANoptosis

RIPK1/3 Blockor

Prevents necroptotic cell death and subsequent inflammation.

  

PANoptosis

CEBPG, TFA-P2C, BNIP3

Tissue biomarkers for periodontitis.

  

PANoptosis

TTM

Promotes autophagosome formation and enhances mitophagy-related gene expression, while counteracting LPS-induced suppression of autophagic flux.

Mitigates LPS-induced lysosomal dysfunction.

Increases lysosomal membrane permeability and the secretion of cathepsin B.

Enhances autophagic flux and lowers cathepsin B levels.
