ubiquinone 1

Ubiquinone-1 (UQ-1) 是辅酶 Q 合成的中间体，是人体氧化还原反应中重要的辅酶，参与机体的多种氧化还原反应。

Boscalid 是一种广谱羧酰胺类杀菌剂，通过与线粒体复合物 II 琥珀酸脱氢酶的泛醌位点结合来抑制真菌呼吸。

Coenzyme Q0 (CoQ0)，一种从Antrodia cinnamomea提取的口服醌类化合物，具备促进细胞凋亡(apoptosis)与自噬(autophagy)的作用。该化合物通过抑制HER-2 AKT mTOR信号通路，增强凋亡和自噬机制；同时，调控NFκB AP-1活化，提升Nrf2稳定性，从而缓解炎症及氧化还原失衡。此外，Coenzyme Q0还表现出抗血管生成特性，通过下降MMP-9 NF-κB并提升HO-1信号路径发挥作用。

COQ7-IN-1 is a powerful inhibitor of human coenzyme Q (COQ7), effectively disrupting the synthesis of ubiquinone (UQ) in the body. Notably, COQ7-IN-1 does not disrupt the natural growth of human normal culture cells. This compound proves valuable for investigating the equilibrium between two pathways of UQ supplementation: de novo UQ synthesis and extracellular UQ uptake[1].

Coenzyme Q10 is a component of the electron transport chain and participates in aerobic cellular respiration, generating energy in the form of ATP. In its reduced form, it acts as an antioxidant. Coenzyme Q2 is a precursor of coenzyme Q10 that has 2, rather than 10, isoprenoid units on the ubiquinone base. It can act as an electron acceptor for bacterial Complex I. In mammalian cells, exogenous coenzyme Q2 prevents the production of reactive oxygen species associated with Complex I activity. Forms of coenzyme Q with shorter isoprenoid chains, including coenzyme Q2, induce p53-dependent apoptosis in human B-cell acute lymphoblastoid leukemia BALL-1 cells.

Coumarin-quinone conjugate is a fluorescent substrate for NADH:ubiquinone oxidoreductases.1It is comprised of a coumarin fluorophore conjugated to a ubiquinone analog that can be reduced by NADH:ubiquinone oxidoreductases. It has been used to measure the kinetic parameters of apoptosis-inducing factor mitochondria-associated 2/ferroptosis suppressor protein 1 (AIFM2/FSP1). 1.Doll, S., Freitas, F.P., Shah, R., et al.FSP1 is a glutathione-independent ferroptosis suppressorNature575(7784)693-698(2019)

Coenzyme Q6 (Ubiquinone 30)，一种异戊二烯化的苯醌脂质，主要在呼吸电子传输链中发挥作用，并作为脂质抗氧化剂，具备抗氧化性能，能够防止自由基生成和氧化损伤。

Coenzyme Q8 (Ubiquinone 8) 是一种从秀丽隐杆线虫野生型或长寿命 qm30 和 qm51 clk-1 突变菌株分离的质膜中分离得到的类异戊二烯醌，可介导有氧呼吸链中电子转移，减轻氧化应激。
