依布硒
化合物
依布硒（英語：Ebselen、也稱為PZ 51、DR3305和SPI-1005）是一種合成的有機硒藥物分子，具有抗炎、抗氧化和細胞保護活性。它充當穀胱甘肽過氧化物酶的模擬物，也可以與過氧亞硝酸鹽反應。[1]正在被研究作為再灌注損傷和中風、[2][3]聽覺損失和耳鳴[4][5]和雙向情緒障礙症[6][7]的可能治療藥物。

此外，依布硒也可以有效地對抗艱難擬梭菌感染[8]且它也被證明擁有對抗煙麴黴的抗真菌活性。[9]
依布硒是過氧化氫和氫過氧化物（包括膜結合磷脂和膽固醇酯氫過氧化物）的有效清除劑。幾種依布硒類似物已顯示在硫醇存在下清除過氧化氫。[10]
可能的抗COVID-19活性
初步研究表明，依布硒在基於細胞的測定中表現出對COVID-19的抑制活性。[11][12][13]該效應歸因於通過與活性中心的半胱氨酸（Cys-145）的硫醇基團形成共價鍵對主要蛋白酶的不可逆抑制。[11]
合成
通常，依布硒的特徵支架，苯並異硒唑酮環系統的合成，可以通過伯胺（RNH2）與2-(氯硒)苯甲酰氯（路線一）的反應、[14]苯甲酰苯胺的鄰位鋰化和氧化環化來實現（路線二）由溴化銅（CuBr2）介導，[15]或通過高效的銅催化的鄰鹵代苯甲酰胺的硒化/雜環化，這是Kumar等人開發的一種方法[16]（路線三）。
