Five aldo-keto reductases (AKR1C1, AKR1C3, AKR1C21, AKR1B1 andAKR1B10) are regarded as both diagnostic markers and therapeutic targets in the treatment of several types of cancer. We searched inhibitors of the enzymes, investigated selectivity determinants of the inhibitor-binding to the enzymes, and synthesized potent and selective inhibitors. (1) AKR1C1 inhibitor: Potent salicylic acid-based inhibitorswere synthesized based on the crystal structure of the enzyme. (2) AKR1C3 inhibitor: Among the inhibitors found, tolfenamic acid and baccharin were the most potent and selective inhibitors, respectively. A baccharin derivative with high inhibitory potency and selectivity was synthesized. (3) AKR1C21 inhibitor: Cholanic acid and its derivatives were found to be potent inhibitors. (4) AKR1B1 inhibitor: A selective and potent inhibitorwas synthesized based on the structure of an alkaloid rhetsinine. (4) AKR1B10 inhibitor:Some drugs (such as mefenamic acid) and natural products (mangostin, oleanolic acid,caffeic acid phenethyl ester) were found to be selective inhibitors. A caffeic acid phenethyl ester derivative with high inhibitory potency and selectivity was synthesized.

在几种类型的癌症治疗时，五个Aldo-Keto还原酶（AKR1C1，AKR1C3，AKR1C21，AKR1B1 ANDAKR1B10）被认为是治疗几种类型癌症的诊断标记和治疗靶标。我们搜索了酶的抑制剂，研究了对酶的抑制剂结合的选择性决定因素，以及合成的有效和选择性抑制剂。 （1）AKR1C1抑制剂：基于酶的晶体结构合成的有效水杨酸抑制剂。 （2）AKR1C3抑制剂：在发现的抑制剂中，Tolfenamic Acid和Baccharin分别是最有效，最有选择性的抑制剂。合成具有高抑制效力和选择性的Baccharin衍生物。 （3）AKR1C21抑制剂：发现胆酸及其衍生物是有效的抑制剂。 （4）AKR1B1抑制剂：基于生物碱晶状定结构合成的选择性和有效的抑制剂。 （4）AKR1B10抑制剂：某些药物（例如甲酸酸）和天然产物（芒果素，少量酸，咖啡酸苯乙酯）被发现是选择性抑制剂。合成了具有高抑制效力和选择性的咖啡酸苯乙酯衍生物。
