惕格列定

化学物质

惕格列定(英文:tigloidine)是一種托品烷生物鹼,化學式:C13H21NO2,其作為一種生物鹼廣泛分布於茄科植物中,包括軟木茄(學名:Duboisia myoporoides[1],燈籠果(學名:Physalis peruviana[2]曼陀羅等。為惕格酸與3β-托品醇的。臨床上常作抗膽鹼劑,用於治療帕金森等神經退行疾病[3]。商品名為托品林(Tropigline)[4]

生物合成

惕格列定作為茄科植物次級代謝產物托品烷生物鹼的一種[5],其生物合成主要由托品酮經還原酶還原成3β-托品醇(假託品醇),然後與惕格醯假託品合成酶催化3β-托品醇與惕格醯輔酶A(tigloyl-CoA)發生酯化反應得到[6]

醫學用途

1950年Trautner和McCallum發現惕格列定使反覆刺激的牛蛙縫匠肌產生疲勞,60年代報道其對帕金森病、亨廷頓舞蹈症、痙攣性截癱有效果[7]。1968年美國批准其用於治療帕金森病[8]

惕格列定是阿托品的替代藥物,用於治療帕金森。與阿托品相比,其頭痛、喉嚨乾燥、瞳孔擴大等不良反應率更低[6]
