发现和SAR的第一个临床阶段蛋白激酶CK2抑制剂5-(3-氯苯基氨基)苯并[ c ] [2,6]萘吡啶-8-羧酸(CX-4945)
摘要:
本文中,我们对CX-4945(25n)的发现进行了编年史,CX-4945是蛋白激酶CK2的一流的,口服可生物利用的ATP竞争性抑制剂,在癌症的临床试验中得到了证实。CK2长期以来一直被认为是主要的癌症药物靶标,因为CK2的失调和过度表达在促进癌症的生存和抗凋亡途径中起着重要的作用。这些生物学特性以及CK2的小ATP结合位点对选择性抑制剂设计的适用性,使我们开发出了新型的癌症治疗剂。导致25n(K i = 0.38 nM)的最优化是通过分子建模指导的,这表明25n的强结合由疏水相互作用,与Lys68形成的离子桥以及与铰链区的氢键结合而成。发现25n具有高度选择性,可跨物种口服生物利用(20-51%),并且在异种移植模型中有效。25n的发现将首次使CK2在人类中具有治疗靶向性。

Synthesis and Structure–Affinity Relationships of Selective High-Affinity 5-HT<sub>4</sub> Receptor Antagonists: Application to the Design of New Potential Single Photon Emission Computed Tomography Tracers
The work described herein aims at finding new potential ligands for the brain imaging of 5-HT4receptors (5-HT4Rs) using single-photon emission computed tomography (SPECT). Starting from the nonsubstituted phenanthridine compound 4a, exhibiting a Ki value of 51 nM on the 5-HT4R, we explored the structure–affinity in this series. We found that substitution in position 4 of the tricycle with a fluorine
