Application

AP-18 is a selective TRPA1 channel blocker. AP-18 blocks the transient receptor potential ankyrin 1 receptors and can reduce chronic pain associated with arthritis. AP-18 reduces cinnamaldehyde-induced nociception in vivo and blocks cold- and mustard oil-induced activation of mouse TRPA1 but not capsaicin-induced activation. AP-18 reverses CFA-induced mechanical hyperalgesia in mice

Biochem/physiol Actions

AP-18 is a selective TRPA1 channel blocker. Transient receptor potential A1 (TRPA1) plays a central role for chemical sensing in the pain pathway. AP-18 is a novel TRPA1 channel blocker. It reduces cinnamaldehyde-induced nociception in vivo and blocks cold- and mustard oil-induced activation of mouse TRPA1 but not capsaicin-induced activation demonstrating selectivity vs. TRPV11. AP-18 reverses CFA-induced mechanical hyperalgesia in mice.

Transient receptor potential ankyrin 1 (TRPA1) is a non-selective cation channel that is broadly expressed in sensory pathways, such as the trigeminal and vagus nerves. It is capable of detecting various irritants in inspired gasses and is activated during hypoxia.

H2O2 has a variety of actions in skin wounds but has been rarely studied in deep muscle tissue. Based on response to the transient receptor potential ankyrin 1 antagonists after plantar incision, we hypothesized that H2O2 exerts nociceptive effects via

Adipocyte lines are a useful tool for adipocyte research. Recently, a new preadipocyte line designated AP-18 was established from subcutaneous tissue of the C3H/He mouse. In this study, we further characterized AP-18 cells. Adipocyte differentiation was assessed by accumulation of
