  Development of Potent and Selective Inhibitors of Aldo–Keto Reductase 1C3 (Type 5 17β-Hydroxysteroid Dehydrogenase) Based on N-Phenyl-Aminobenzoates and Their Structure–Activity Relationships

  摘要：

  Aldo-keto reductase 1C3 (AKR1C3; type 5 17 beta-hydroxysteroid dehydrogenase) is overexpressed in castration resistant prostate cancer (CRPC) and is implicated in the intratumoral biosynthesis of testosterone and 5 alpha-dihydrotestosterone. Selective AKR1C3 inhibitors are required because compounds should not inhibit the highly related AKR1C1 and AKR1C2 isoforms which are involved in the inactivation of Sa-dihydrotestosterone. NSAIDs, N-phenylanthranilates in particular, are potent but nonselective AKR1C3 inhibitors. Using flufenamic acid, 2-{[3-(trifluoromethyl)phenyl]amino}benzoic acid, as lead compound, five classes of structural analogues were synthesized and evaluated for AKR1C3 inhibitory potency and selectivity. Structure-activity relationship (SAR) studies revealed that a meta-carboxylic acid group relative to the amine conferred pronounced AKR1C3 selectivity without loss of potency, while electron withdrawing groups on the phenylamino B-ring were optimal for AKR1C3 inhibition. Lead compounds did not inhibit COX-1 or COX-2 but blocked the AKR1C3 mediated production of testosterone in LNCaP-AKR1C3 cells. These compounds offer promising leads toward new therapeutics for CRPC.

  The present invention relates to a process for the preparation of N-aryl amine and N-aryl amide compounds. Generally, the process of the present invention involves reacting a compound having a primary or secondary amino or amido group with an arylating compound, in the presence of a weak base and a transition metal catalyst, under reaction conditions effective to form an N-aryl amine or N-aryl amide compound, the transition metal catalyst comprising a Group 8 metal, e.g., Ni, Pd, or Pt, and at least one carbene-containing ligand. Typically, the transition metal catalyst is formed in a preceding step from the conjugate acid form of the carbene ligand, a stoichiometric amount of a strong base, and a Group 8 metal atom or ion.

  本发明涉及一种制备N-芳基胺和N-芳基酰胺化合物的方法。一般来说，本发明的方法涉及在弱碱和过渡金属催化剂的存在下，将具有一级或二级氨基或酰胺基的化合物与芳基化合物反应，形成N-芳基胺或N-芳基酰胺化合物的反应条件有效。过渡金属催化剂包括第8族金属，例如Ni、Pd或Pt，以及至少一个含卡宾的配体。通常，过渡金属催化剂是在前一步中由卡宾配体的共轭酸形式、一定量的强碱和第8族金属原子或离子形成的。
