HC-030031是一种选择性的TRPA1通道阻断剂，可以拮抗AITC和formalin引起的钙流入，IC50分别为6.2μM和5.3μM。HC-030031能快速且可逆阻断AITC或Formalin引起的内向和外向电流，也能抑制N-methylmaleimide和Electrophillic前列腺素引起的TRPA1激活。HC-030031不抑制TRPV1, TRPV3, TRPV4 hERG, 或NaV1.2通道介导的电流。

TRPA1

HC-030031 is a substituted theophylline derivative. Potent and selective TRPA1 inhibitor. HC-030031 can block both inward and outward currents elicited by AITC or formalin rapidly and reversibly and also blocks the activation of TRPA1 by N-methylmaleimide and by electrophillic prostaglandins. It does not block currents mediated by TRPV1, TRPV3, TRPV4 hERG, or NaV1.2 channels.

HC-030031 can be delivered to animals orally, by inhalation, or by injection. Oral administration (100 mg/kg) of HC-030031 significantly reversed mechanical hypersensitivity in rat models of chronic inflammatory or neuropathic pain, while local injection (100 μg) into inflamed mouse hind paws attenuated mechanical, but not heat, hypersensitivity.

TRPA1 mediates mechanical sensitization in nociceptors during inflammation.
