Mequinol (Leucobasal) is a synthetic derivate of hydroquinone and depigmenting agent. Although the exact mechanism of the depigmenting effects of mequinol remains unclear, it may exert its effect by oxidation of tyrosinase to cytotoxic products in melanocytes.

Thymohydroquinone (Thymoquinol) is a monoterpenoid phenolic compound found in thyme, oregano, and other plants in the labiaceae family. Thymohydroquinone inhibits cancer cell growth, reduces oxidative stress and modulates inflammatory responses, scoured 2, 2-diphenyl-1-PicrylHydrazyl radicals in a cell-free assay (IC50 = 2.4 μg ml), In the oxygen radical absorption capacity (ORAC) test at concentrations of 1.6 to 6.4 μg ml, Its Trolox value was 2.6. Thymus hydroquinone inhibited the growth of A2780, OVCAR-8 and CIS-A2780 ovarian cancer cells (IC50 were 3.1, 8.9 and 9.8 μM, respectively) and human ovarian immortalized epithelial cells (IC50 = 14 μM). It also inhibited Plasmodium falciparum in vitro (IC50 = 15.9 μM).

2-Prenylhydroquinone-1-glucoside is a useful organic compound for research related to life sciences and the catalog number is T131092.

Tetrachlorohydroquinone dimethyl ether is a useful organic compound for research related to life sciences and the catalog number is T123888.

2,6-Dimethylhydroquinone (2,6-DMHQ), an endogenous metabolite, consists of a benzene ring substituted with two hydroxyl (OH) groups located at positions 1 and 4, along with two methyl (CH3) groups at positions 2 and 6. [2,6-dimethylbenzene-1,4-diol]

Colutehydroquinone is an antifungal isoflavonoid from Colutea arborescens.

Tetrachlorohydroquinone (TCHQ), a metabolite of the organochlorine biocide pentachlorophenol, is cytotoxic to RTL-W1 rainbow trout liver cells (EC50 = 1.55 μM in a neutral red assay). TCHQ increases production of reactive oxygen species (ROS), inhibits apoptosis, and induces loss of mitochondrial membrane potential and necrosis in splenocytes.

Trimethylhydroquinone is a useful organic compound for research related to life sciences. The catalog number is T65486 and the CAS number is 700-13-0.

Collagen-IN-1 (compound 3) is an ortho-carbonyl hydroquinone derivative that selectively inhibits collagen. It non-competitively inhibits agonist-induced platelet aggregation, with an IC50 value of 1.77 μM. Collagen-IN-1 reduces P-selectin expression, glycoprotein IIb IIIa activation, and the release of adenosine triphosphate and CD63 from platelets. This compound is promising for research into platelet-related thrombosis diseases [1].

Ansatrienin B is an ansamycin antibiotic and antifungal agent first isolated from S. collinus and S. rishiriensis., In fetal rat long bones, it is an inhibitor of parathyroid hormone-induced calcium release (IC50 = 21 nM), which is a measure of bone resorption, and pp60c-src kinase (IC50 = 50 nM). It is an inhibitor of translation at the protein synthesis stage by specific inhibition of L-leucine incorporation (IC50 = 58 nM in A549 cells). It also inhibits TNF-α-induced expression of intercellular adhesion molecule-1 (ICAM-1; IC50 = 300 nM). Early in vitro studies showed that ansatrienin B potentiates the chemotherapeutic action of 5-fluorouracil , cisplatin , bleomycin , mitomycin C , and 6-mercaptopurine. Ansatrienin B is a hydroquinone form of ansatrienin A .

(+/-)-1,2-Propylene-d6 Oxide (Stabilized with hydroquinone) is a deuterated compound of (+/-)-1,2-Propylene Oxide. (+/-)-1,2-Propylene Oxide has a CAS number of 75-56-9.

Ethonafide is an anthracene-containing derivative of amonafide that belongs to the azonafide series of anticancer agents. The lack of cross-resistance in multidrug-resistant cancer cell lines and the absence of a quinone and hydroquinone moiety make ethonafide a potentially less cardiotoxic replacement for existing anthracene-containing anticancer agents. Ethonafide was cytotoxic against three human prostate cancer cell lines at nanomolar concentrations. Ethonafide was found to be better tolerated and more effective at inhibiting tumor growth compared with mitoxantrone in a human xenograft tumor regression mouse model. Mechanistically, we found that ethonafide inhibited topoisomerase II activity by stabilizing the enzyme-DNA complex, involving both topoisomerase IIalpha and -beta. In addition, ethonafide induced a potent G(2) cell cycle arrest in the DU 145 human prostate cancer cell line. By creating stable cell lines with decreased expression of topoisomerase IIalpha or -be......

HTHQ (HTHQ(1-O-Hexyl-2,3,5-trimethylhydroquinone)), a hydroquinone monoalkyl ether, is an effective anti-oxidative agent. HTHQ is a potent anti-lipid-peroxidative compound and its antioxidation activity to be extremely elevated in biological systems, such as that of liver microsomes via the generation of stable free radicals.

Tetrahydroauroglaucin, a hydroquinone derivative, exhibits antioxidative effects [1].
