Novel methyl 2-hydroxy-5-substituted benzoate derivatives (2a–2i) were synthesized by esterification of methyl gentisate and long-chain fatty acids. The compounds were structurally confirmed by MS, IR, 1H NMR, and HR-MS spectroscopy. A preliminary bioassay test demonstrated that compounds 2b, 2c, 2f, 2g, 2h showed stronger inhibition of tyrosinase activity. Further pharmacological experiments showed that after substitution modification of compounds 2b, 2f, 2g, and 2h, they have no potential toxicity and phototoxicity.
新型甲基2-羟基-5-取代苯甲酸酯衍生物(2a–2i)通过甲基音香酸和长链脂肪酸的酯化反应合成。通过质谱(MS)、红外光谱(IR)、氢谱(1H NMR)和高分辨率质谱(HR-MS)确认了化合物的结构。初步生物测定结果表明,化合物2b、2c、2f、2g和2h对酪氨酸酶活性具有更强的抑制作用。进一步的药理实验表明,在对化合物2b、2f、2g和2h进行取代修饰后,它们没有潜在的毒性和光毒性。
