壬二酸（又稱杜鵑花酸）（英語：Azelaic acid，缩写AzA）是一種飽和二羧酸，化學式為HOOC(CH₂)₇COOH。在標準狀態下，純壬二酸呈白色粉末狀。壬二酸自然存在於小麥、黑麥和大麥等榖物中。壬二酸可作為聚合物和增塑劑等化工產品的前體，它也是外用抗痤瘡藥物和某些頭髮和皮膚養護劑的成分。^[2]

製備

在工業上，壬二酸可透過油酸的臭氧分解生產，而過程的副產品為壬酸。生活在正常皮膚上的真菌秕糠馬拉癬菌會自然分泌壬二酸，而壬二酸也是壬酸的細菌分解產物。

9-十八碳烯酸经过强氧化剂（如高锰酸钾氧化）可以制得壬二酸。^[3]

生物作用

在植物中，壬二酸是感染後防禦反應中所涉及的一種植物激素。^[4]它能誘導水楊酸的積累，而水楊酸則是植物防禦反應的重要組成部分。^[5]

應用

聚合物及相關材料

壬二酸酯可用於潤滑劑和增塑劑。在潤滑劑工業中，它可用作鋰潤滑脂的增稠劑。壬二酸與六亞甲基二胺的共聚物是特種塑料尼龍-6,9。^[2]

醫學用途

壬二酸可用於治療輕度至中度的粉刺性和炎性痤瘡。^[6]^[7]壬二酸能殺死感染毛孔的痤瘡細菌，還會降低角蛋白的產生，而角蛋白是一種促進痤瘡細菌生長的天然物質。^[8]由於它具有消炎作用，壬二酸還可以用作治療玫瑰痤瘡的外用藥物。它可以治療玫瑰痤瘡引起的腫塊和腫脹。壬二酸的作用機制是通過抑制過度活躍的蛋白酶活性，該蛋白酶能將導管素轉化為抗微生物肽LL-37。^[9]壬二酸也可用於治療皮膚色素沉著，包括黃褐斑和炎症後色素過度沉著，尤其是對於那些膚色較深的人。它也被推薦作為對苯二酚的代替品。^[10]作為酪氨酸酶抑製劑，壬二酸可抑制黑色素的合成。^[11]

與治療脫髮藥物非那甾胺和度他雄胺（英语：dutasteride）相似的是，壬二酸也是一種有效的5α還原酶抑制劑。^[12]
