q-8

Coenzyme Q8 (Ubiquinone 8) is an isoprenoid quinone isolated from the plasma membrane of wild-type or long-lived qm30 and qm51 clk-1 mutant strains of Cryptomeria cepacia that mediates electron transfer in the aerobic respiratory chain and reduces oxidative stress.

LXQ-87 is an orally administered, non-competitive inhibitor of PTP1B with an IC50 of 1.061 μM, demonstrating hypoglycemic activity. It alleviates insulin resistance and enhances cellular glucose uptake, making it useful for type 2 diabetes research.

Q8 is an antagonist of cysteinyl leukotreine receptor. Q8 inhibits VEGF-independent angiogenesis.

CQ80 is an inhibitor of PEPD/XPNPEP1, functioning by activating the CARD8 inflammasome.

LEQ803 (N-DesmethylRibociclib) is a metabolite of the CDK4/6 inhibitor Ribociclib, produced through metabolism by CYP3A4. This compound holds potential applications in the field of oncology.

LAQ824 (Dacinostat (NVP-LAQ824)) is a novel HDAC inhibitor with IC50 of 32 nM and is an activator of the p21 promoter.

(E/Z)-LAQ824 is an inhibitor of histone deacetylase.

BMS 180680 is a novel catechol-containing monolactam antibacterial active agent, which is the most effective compound against many species of Enterobacteriaceae.

Cinamolol is a beta blocker.

Q-VD-OPh is an irreversible caspase inhibitor with an IC50 value of 48 nM against caspase-7 and between 25 and 400 nM against caspase-1, 3, 8, 9, 10, 12. Q-VD-OPh inhibits HIV infection and can cross the blood-brain barrier.

2-Hydroxyanthraquinone is an anthraquinone that has been found inSpermacoce latifoliaand has antibacterial and estrogenic activities.1,2It is active againstB. subtilisandB. cereus(MICs = 1.9 and 62.5 μg/ml, respectively).12-Hydroxyanthraquinone (19 μM) induces estrogen receptor α (ERα) activation in a yeast two-hybrid assay.2 1.Luo, Y., Shen, H.-Y., Shen, Q.-X., et al.A new anthraquinone and a new naphthoquinone from the whole plant of Spermacoce latifoliJ.
