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-托品醇的酯。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]。
