  Nonpeptide Angiotensin II Receptor Antagonists. Synthesis, in vitro Activity, and Molecular Modeling Studies of N-[(Heterobiaryl)methyl]imidazoles

  摘要：

  With the aim of explaining the influence of the structural changes on the biphenylic moiety on the activity, a series of N-[(heterobiaryl)methyl]imidazoles (I), constructed on the model of DuPont compounds by replacing either the central or terminal phenyl ring with a heteroaromatic one, such as furan, thiophene, thiazole, and pyridine, was synthesized. Compared to the reference DuPont compound (EXP-7711), all the heterobiaryl derivatives showed a reduced potency both in receptor binding (rat adrenal capsular membranes) and in the functional assay (angiotensin II-induced contraction of rabbit aorta strips). The lower activity was justified by the extensive molecular modeling studies, which took into consideration the conformational and electrostatic features of several heterobiaryl derivatives. On the basis of the results obtained, it was hypothesized that the central aromatic ring of the biarylic portion works as a spacer, orienting in the right way the terminal phenyl ring, whose electronic distribution is, instead, crucial to its fitting well with a lipophilic pocket at the receptor site.

• Discovery of 5-(3-Chlorophenylamino)benzo[<i>c</i>][2,6]naphthyridine Derivatives as Highly Selective CK2 Inhibitors with Potent Cancer Cell Stemness Inhibition

  concurrent CK2 along with cancer stem cell (CSC) inhibitory activities are rare in a single small molecule. Herein, a series of 5-(3-chlorophenylamino)benzo[c][2,6]naphthyridine derivatives were synthesized using a known CK2 inhibitor, silmitasertib (CX-4945), as the lead compound. Among the resulting compounds, 1c exhibited stronger CK2 inhibitory activity with higher Clk2/CK2 selectivity than CX-4945

  多功能实体最近对于开发抗癌化疗药物具有吸引力。但是，在单个小分子中很少有具有并发CK2和癌症干细胞（CSC）抑制活性的实体。在此，使用已知的CK2抑制剂西米塔塞替尼（Cilmitasertib（CX-4945））作为前导化合物合成了一系列5-（3-氯苯基氨基）苯并[ c ] [2,6]萘啶衍生物。在所得化合物中，1c与CX-4945相比具有更强的CK2抑制活性和更高的Clk2 / CK2选择性。明显地，1c可以调节Akt1（ser129）-GSK-3β（ser9）-Wnt /β-catenin信号通路并抑制茎标记ALDH1A1，CSC表面抗原和茎基因的表达，显示出强大的CSC抑制活性。此外，与CX-4945钠盐相比，1c还显示出优异的药代动力学和抗肿瘤活性，且无明显毒性。1c的良好抗增殖和抗肿瘤活性，对CK2的高抑制选择性以及对癌细胞干性的有效抑制作用使该分子成为治疗癌症的候选药物。

  The palladium-catalyzed cross-coupling reaction of bromobenzenes or bromoheteroarenes such as pyridine, thiophene, indole with (Z)-1-ethoxy-2-tributylstannylethene gives good yields of the corresponding (Z)-1-ethoxy-2-(aryl and heteroaryl)ethenes. This method is effective for introducing an ethoxyethenyl group into an aromatic and heteroaromatic ring and is proved to have versatile utility for the
