HTHQ
Based on 2 publication(s) in Google Scholar
HTHQ (1-O-hexyl-2,3,5-trimethylhydroquinone) is a potent lipophilic phenolic antioxidant. HTHQ has considerable anti-oxidative activity by directly reacting with reactive oxygen species (ROS) and scavenging ROS to form more stable free radicals.

Biological Activity
ROS[1]
HTHQ (0-100 μM; 24 hours; PC12 cells) treatment increases cell viabilities in a dose-dependent manner[1].
HTHQ (10 μM; 0.6-24 hours; PC12 cells) inhibits 3,4-L-Dihydroxyphenylalanine (L-DOPA) -induced phosphorylation of sustaines extracellular signal-regulated kinases (ERK1/2), p38 mitogen-activated protein kinase (MAPK), and c-Jun N-terminal kinase (JNK1/2). HTHQ also normalizes L-DOPA-reduced Bcl-2-associated death protein (Bad) phosphorylation and Bcl-2-associated X protein (Bax) expression, promoting cell survival[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 25 mg/mL (105.78 mM); Suspended solution; Need ultrasonic
