生物活性	Dequalinium chloride is an Apamin (HY-P0256)-sensitive potassium channel selective blocker. Dequalinium chloride is a cationic, lipophilic mitochondrial poison. Dequalinium chloride is also an antagonist pf α7 nAChR, and an anti-microbial antiseptic agent with a broad bactericidal and fungicidal activity^[1]^[2]^[3]^[4].
体外研究 (In Vitro)	Dequalinium chloride 可阻断豚鼠肝细胞中血管紧张素 II (100 nM) 诱发的 K⁺ 损失，IC₅₀ 为 1.5 μM^[5]。 Dequalinium (0-100 μg/mL, 72 h) chloride 抑制人 Pca 细胞系 (PC3、DU145、LNCaP、MDA-PCA-2B) 中的细胞生长，并诱导 PC3 细胞中的细胞凋亡 (0.9 μM, 4 h)^[7]。

体内研究 (In Vivo)	Dequalinium chloride 在小鼠中的 LD₅₀ 为 18.3 mg/kg (腹腔注射，单次)^[2]。 Dequalinium chloride (2 mg/kg，腹膜内注射，每日一次，持续 10 天) 抑制小鼠膀胱癌 (MB49皮下瘤) 的肿瘤生长^[3] 。 Dequalinium chloride (2 mg/kg，皮下注射) 可减少二异丙基氟磷酸盐引起的小鼠震颤 (有机磷中毒)^[6]。
