[3-prenyl-4-(dihydrocinnamoyloxy)cinnamic acid], a component of propolis, was shown to be both potent (Ki 56 nM) and highly isoform-selective inhibitor of AKR1C3. In this study, a series of derivatives of baccharin were synthesized by replacing the 3-prenyl moiety with aryl and alkyl ether moieties, and their inhibitory activities for the enzyme were evaluated. Among them, two benzyl ether derivatives, 6m and
醛糖酮还原酶超家族的人类成员(AKR1C3)的抑制剂被认为是治疗前列腺癌和乳腺癌的有前途的疗法。Baccharin [3-异戊烯基-4-(二氢肉桂酰氧基)肉桂酸],蜂胶的一种成分,既是有效的(K i 56 nM),又是AKR1C3的高度同工型选择性抑制剂。在这项研究中,通过用芳基和烷基醚部分取代3-异戊烯基部分,合成了一系列的baccharin衍生物,并评估了其对酶的抑制活性。其中,两种苄基醚衍生物6m和6n表现出与baccharin相当的抑制力。AKR1C3中6m的分子对接使得(E)-3- 3-[(3-羟基苄基)氧基] -4-[(3-苯基丙酰基)氧基]苯基}丙烯酸(14),其效能(K i 6.4 nM)和选择性可与baccharin相比提高。此外,14显着降低了AKR1C3的雄激素和具有细胞毒性的4-氧代-2-壬烯醛的细胞代谢,其浓度远低于baccharin。
