programmed cell death

Concanavalin A is a natural product, a phytoalexin (glycan-binding protein). Concanavalin A has antitumor activity and can also induce acute liver injury.

Polyphyllin D induces apoptosis via the mitochondrial apoptotic pathway as evidenced by decreased Bcl-2 expression levels, disruption of MMP and increased Bax, cytochrome C, and cleaved-caspase-3 levels. Polyphyllin D has an anti-angiogenic effect. Polyphyllin D has toxicity in human RBCs as well as its underlying mechanism for the hemolysis and eryptosis erythroptosis. Polyphyllin D has strong anticancer activity, can overcome drug resistance in R-HepG2 cells and elicit programmed cell death via mitochondrial dysfunction.

Apoptosis Inhibitor was a novel inhibitor of programmed cell death associate with caspase-3 inhibition.

Trioxsalen (Trioxysalen) is a furanocoumarin and a psoralen derivative, in conjunction with UV-A for phototherapy treatment of vitiligo and hand eczema. After photoactivation it creates interstrand cross-links in DNA, which can cause programmed cell death.

Phosphorylethanolamine (O-Phosphorylethanolamine) is a phosphomonoester metabolite of the phospholipid metabolism. Phosphorylethanolamine is a precursor of phospholipid synthesis and a product of phospholipid breakdown. Phosphomonoesters are present at much higher levels in the brain than in other organs. In developing the brain, phosphomonoesters are normally elevated during the period of neuritic proliferation. This also coincides with the occurrence of normal programmed cell death and synaptic pruning in developing the brain. These findings are consistent with the role of phosphomonoesters in membrane biosynthesis. Phosphorylethanolamine shows a strong structural similarity to the inhibitory neurotransmitter, GABA, and the GABAB receptor partial agonist, 3-amino-propylphosphonic acid. Phosphorylethanolamine is a phosphomonoester which is decreased in post-mortem Alzheimer's disease (AD) brain.

Chrysotobibenzyl, a bibenzyl found in the stem of Dendrobium pulchellum, may facilitate anoikis--a form of programmed cell death that occurs in anchorage-dependent cells when they detach from the surrounding extracellular matrix (ECM)-- and inhibit the growth of lung cancer cells in anchorage-independent condition. Preliminary data obtained discloses the inhibitory effect on cancer cell metastasis of the isolated compounds and may provide a new approach for cancer drug development.

Benzosceptrin C is a PD-L1 inhibitor that promotes the degradation of programmed cell death ligand (PD-L1) via a lysosomal pathway, enhances T-cell cytotoxicity, and demonstrates antitumor activity [1].
