Hepatotoxicity

DI-1859 is a DCN1 and cullin 3 inhibitor with a K_i of <1 nM against human DCN1. DI-1859 forms a covalent bond with Cys115 of DCN1, cleaves its dimethylamino group, disrupts the DCN1-UBC12 interaction, and selectively inhibits the neddylation modification of cullin 3 relative to other cullins. DI-1859 inactivates CRL3, promotes the accumulation of NRF2 and SLC7A11, upregulates the expression of HO-1 and NQO1, reduces reactive oxygen species (ROS) levels, enhances insulin signaling, promotes insulin secretion, activates RhoA, regulates the phosphorylation of AKT, without completely blocking the neddylation modification of cullin 3 or restoring the expression of IRS-1. DI-1859 can be used in the research of Acetaminophen (HY-66005)-induced hepatotoxicity, hyperglycemia, metabolic dysfunction-associated steatotic liver disease, insulin resistance, breast cancer and lung cancer.

Prothioconazole is an orally active broad-spectrum fungicide. Prothioconazole weakly inhibits CaCYP51 activity in Candida albicans, with an apparent IC₅₀ of approximately 120 μM. Prothioconazole disrupts Microtubule stability by reducing the acetylation level of α-tubulin. Prothioconazole induces Mitochondrial dysfunction, oxidative stress, DNA damage, and Apoptosis. Prothioconazole accumulates ¹⁴-methylated sterols and depletes ergosterol in cells, culture media, plants, and animals. Prothioconazole interferes with pyruvate metabolism and glycolysis/gluconeogenesis processes in mouse liver, downregulates Fasn mRNA expression, and induces hepatotoxicity and renal metabolic disorders. Prothioconazole reduces the fertility of female mice. Prothioconazole inhibits body weight gain and increases liver/kidney indices in mice. Prothioconazole can be used in studies related to candidiasis.

Nodularin is a hepatotoxin, tumor promoter, and protein phosphatase inhibitor. Nodularin induces apoptosis (apoptosis) in normal cells (including caspase activation, upregulation of Bcl‑XS, and upregulation of BAX/P53), triggers hyperphosphorylation of the MAPK/ERK, mTOR/S6K and p38 MAPK signaling pathways, and induces oxidative stress, endoplasmic reticulum membrane instability, peroxisome proliferation and increased lysosomal enzyme activity. Nodularin promotes DEN (HY-N7434)-initiated hepatocyte proliferation and adenoma formation, and inhibits proliferation, phagocytosis and chemotaxis of normal lymphocytes, oocyte maturation and vitellogenesis, as well as angiogenesis. Nodularin exhibits hepatotoxicity, reproductive and endocrine toxicity, and embryonic developmental toxicity in various animal models. Nodularin can be used in studies related to liver cancer, hepatotoxicity and reproductive endocrine toxicity.

D-Tetramethrin is a type I synthetic pyrethroid insecticide and hepatotoxicity inducer. D-Tetramethrin induces oxidative stress in the liver of zebrafish. D-Tetramethrin induces Apoptosis and inflammatory responses. D-Tetramethrin causes severe liver damage in zebrafish. D-Tetramethrin can be used in studies related to hepatotoxicity.

Fluindarol is a phenylindandione derivative and an orally active anticoagulant. Fluindarol acts as a toxicant that induces organ and tissue haemorrhages and liver parenchymal necrosis in rats. Fluindarol exhibits acute and cumulative preclinical toxicity in rats, rabbits, and dogs, with higher toxicity in female rats than male rats. Fluindarol lacks analgesic action, produces only minor blood pressure effects, and does not alter circulation, respiration, CNS, or cardiac activity. Fluindarol is considered too toxic for clinical use based on preclinical data.

Chitohexaose hexahydrochloride is a small molecular polysaccharide. Chitohexaose hexahydrochloride inhibits the binding of AgW to TLR4. Chitohexaose hexahydrochloride upregulates IL-10, inhibits LPS-induced upregulation of ROS, induces alternative activation of macrophages/monocytes, and suppresses LPS-induced production of TNF-α, IL-1β and IL-6. Chitohexaose hexahydrochloride reverses the mortality of mice challenged with APAP or LPS. Chitohexaose hexahydrochloride can be used in research related to Acetaminophen (HY-66005)-induced hepatotoxicity and endotoxemia.
