Tetrahydropiperine 是胡椒碱的环己基类似物,也是第一种天然芳基戊酰胺,从Piper longum分离得到。它对细胞色素 P450 (CYP) 同工型 CYP1A1/芳基烃羟化酶 (AHH;IC50=23 μM)具有抑制作用。
产品描述
TETRAHYDROPIPERINE is a natural product derived from piperine, can be used to treat convulsion, epilepsy, relieve pain, and control insects.
体内活性
TETRAHYDROPIPERINE is an agonist of transient receptor potential vanilloid type 1 (TRPV1; EC50 = 6.3 μM)[1]. It inhibits the cytochrome P450 (CYP) isoform CYP1A1/arylhydrocarbon hydroxylase (AHH; IC50 = 23 μM) and 7-methoxycoumarin O-demethylase (MOCD) activity (IC50 = 25 μM) in rat liver microsomes[2].Tetrahydropiperine increases skin pigmentation in a mouse model of vitiligo when 100 μl of a 175 mM solution is administered topically, an effect that can be enhanced by subsequent suberythemal ultraviolet radiation (UVR)[3].
动物实验
The test compounds were PIP [5-(3,4-methylenedioxyphenyl)-2,4-pentadienoylpiperidine], tetrahydropiperine [THP, 5-(3,4-methylenedioxyphenyl)-pentanoylpiperidine], a cyclohexyl analogue of piperine [CHP, 5-(3,4-methylenedioxyphenyl)-2,4-pentadienoylcyclohexylamine], and reduced CHP [rCHP, 5-(3,4-methylenedioxyphenyl)-2,4-pentanoylcyclohexylamine].?Sparsely pigmented, HRA/Skh-II mice were randomized to receive topical treatment with test compounds or vehicle twice a day for five days a week, with or without ultraviolet (UV) irradiation on 3 days a week.?Treatment was either continuous or interrupted to evaluate fading and repigmentation.?Skin inflammation and pigmentation were evaluated regularly during treatment.?DOPA+ melanocytes were determined histologically at the termination of treatment[3].
