In this work, we describe the design, synthesis and SAR studies of 2-benzylidenebenzofuran-3-ones (aurones), a new family of potent inhibitors of CK2. A series of aurones have been synthesized. These compounds are structurally related to the synthetic flavones and showed nanomolar activities towards CK2. Biochemical tests revealed that 20 newly synthesized compounds inhibited CK2 with IC₅₀ values in the nanomolar range. Further property-based optimization of aurones was performed, yielding a series of CK2 inhibitors with enhanced lipophilic efficiency. The most potent compound 12m (BFO13) has CLipE = 4.94 (CLogP = 3.5; IC₅₀ = 3.6 nM) commensurable with the best known inhibitors of CK2.

在这项工作中，我们描述了2-亚苄基苯并呋喃-3-酮（aurones）的设计，合成和SAR研究，该化合物是CK2的新型强效抑制剂。已经合成了一系列的金酮。这些化合物在结构上与合成的黄酮有关，并显示出对CK2的纳摩尔活性。生化测试表明，有20种新合成的化合物抑制CK2，IC ₅₀值在纳摩尔范围内。进行了进一步的基于属性的金质优化，产生了一系列亲脂效率增强的CK2抑制剂。最有效的化合物12m（BFO13）的CLipE = 4.94（CLogP = 3.5; IC ₅₀  = 3.6 nM）与最知名的CK2抑制剂相当。
