1-O-Hexadecyl-sn-glycerol is a biologically active alkyl glyceryl ether that exhibits protective effects against UVB-induced cellular damage by reducing keratinocyte death, reactive oxygen species (ROS) generation, and prostaglandin E2 synthesis in normal human epidermal keratinocytes (NHEKs). additionally, at a concentration of 50 μM, 1-O-Hexadecyl-sn-glycerol significantly enhances coronary flow and left ventricular developed pressure while reducing malondialdehyde (MDA) formation in an ex vivo rat heart model of ischemia and reperfusion injury, thereby demonstrating both cytoprotective and cardioprotective properties.

1. Sesamolin and Sesamin has neuroprotective effect. 2. Sesamolin protects microglia against H2O2-induced cell injury, by inhibiting of p38 MAPK and caspase-3 activation and ROS production. 3. Sesamolin and Sesamin can significantly attenuate the excess g

1. Flavokawain B (Flavokavain B) has potent anti-inflammatory activity, can significantly inhibit production of NO and PGE2 in LPS-induced RAW 264.7 cells. 2. Flavokawain B, the hepatotoxic constituent from kava root, induces GSH-sensitive oxidative stress through modulation of IKK/NF-κB and MAPK signaling pathways. 3. Flavokawain B induces apoptosis, has the potential usefulness of FKB for prevention and treatment of hormone-refractory prostate cancer in an adjuvant setting. 4. Flavokawain B acts through ROS generation and GADD153 up-regulation to regulate the expression of Bcl-2 family members, thereby inducing mitochondrial dysfunction and apoptosis in HCT116 cells.

1. Schisanhenol (Schizanhenol) can protect against adriamycin induced heart mitochondrial toxicity. 2. Schisanhenol has antioxidative effect on human LDL oxidation, may be through scavenging free radicals. 3. Schisanhenol has anti-apoptosis effect on BACSs, may be related to its inhibition of ROS generation.

Stigmane B, a nuclear factor E2-related factor (Nrf2) activator, exhibits neuroprotective effects by downregulating apoptosis and reactive oxygen species (ROS) generation while increasing antioxidant enzyme activities.

Condurango glycoside A activates p53, induces ROS generation, up-regulates p53 expression, and triggers apoptosis as well as premature senescence associated with DNA damage in HeLa cells [1].

Pronqodine A is a quinone isolated from Streptomyces, known for its enzyme inhibitory and anti-inflammatory properties. It targets NAD(P)H:quinone acceptor oxidoreductase 1 (NQO1; IC50 = 131.5 nM). In SW 982 human synovial sarcoma cells, it suppresses bradykinin-induced production of prostaglandin E2 (PGE2), 6-keto PGF1α, and PGD2, with IC50 values of 9, 19, and 7 nM, respectively, and it also promotes the generation of reactive oxygen species (ROS) in these cells.
