| Description | Hexyl gallate (Gallic acid hexyl ester), an alkyl ester derivative of gallic acid, exhibits potent antimalarial activity against Plasmodium falciparum (IC50: 0.11 mM). |
| In vitro | Hexyl gallate （Hexyl 3,4,5-trihydroxybenzoate）专一性抑制RhlR，仅阻断依赖Rhl的鼠李糖脂和蓝藻素的生成，而不影响由Las系统调控的弹性蛋白酶生产和生物膜形成。在10-30 μM浓度下，Hexyl gallate 抑制色素产生，并显示出抗菌活性；该化合物还对CV026细胞表现出抗菌作用。在100及300 μM浓度下，Hexyl gallate 只抑制N-丁酰基高丝氨酸内酯（BHL）的产生，不干扰N-(3-氧代十二烯酰)-L-高丝氨酸内酯（OdDHL）和2-庚基-3-羟基-4(1H)喹啉酮（PQS）的生成[1]。作为抗菌的替代铜化合物，Hexyl gallate 以剂量响应的方式抑制Xanthomonas citri的生长，在30-50 μg/ml范围内活性更为显著，并且其目标是X. citri的细胞膜[3]。 |
