Publication number: 20130116276Abstract: The present invention reveals a new use of neferine. Neferine regulates M8 and V1 subtype of transient receptor potential ion channel (TRPM8 and TRPV1), respectively, in mammalians, including humans, and can be used for preparing medicaments for treating disease related to said ion channel (such as hyperalgesia, Parkinson's disease, painful bladder syndrome, chronic obstructive pulmonary disease, and tumor of skin, prostate, mammary gland, lung, colon, etc). The potency of neferine in the present invention is higher than that of hexahydrothymol.Type: ApplicationFiled: April 13, 2010Publication date: May 9, 2013Applicant: Institute of Chinese Materia Medica, Chinese Academy of Medical SciencesInventors: Tingliang Jiang, Feng Sui, Hairu Huo, Lanfang Li, Shuying Guo
