  Structure–Activity Relationship (SAR) Study of Ethyl 2-Amino-6-(3,5-dimethoxyphenyl)-4-(2-ethoxy-2-oxoethyl)-4H-chromene-3-carboxylate (CXL017) and the Potential of the Lead against Multidrug Resistance in Cancer Treatment

  摘要：

  Multidrug resistance (MDR) against standard therapies poses a serious challenge in cancer treatment, and there is a clinical need for new anticancer agents that would selectively target MDR malignancies. Our previous studies have identified a 4H-chromene system, CXL017 (4) as an example, that can preferentially kill MDR cancer cells. To further improve its potency, we have performed detailed structure-activity relationship (SAR) studies at the 3, 4, and 6 positions of the 4H-chromene system. The results reveal that the 3 and 4 positions prefer rigid and hydrophobic functional groups while the 6 position prefers a meta or para-substituted aryl functional group and the substituent should be small and hydrophilic. We have also identified and characterized nine MDR cancer cells that acquire MDR through different mechanisms and demonstrated the scope of our new lead, 9g, to selectively target different MDR cancers, which holds promise to help manage MDR in cancer treatment.

  6-Arylcoumarins as Novel Nonsteroidal Type Progesterone Antagonists: An Example with Receptor-Binding-Dependent Fluorescence

  摘要：

  Various 6-arylcoumarin derivatives were designed and synthesized as candidate nonsteroidal type progesterone antagonists. 6-Bromocoumarin derivatives were prepared from the corresponding 4-substituted 2-acetoxy-5-bromobenzaldehyde by employing the Still-Gennari modification of the Horner-Wadsworth-Emmons olefination reaction and were converted to 6-arylcoumarins by means of Suzuki-Miyaura cross-coupling reactions. The biological activities of these coumarin derivatives were evaluated by means of alkaline phosphatase assay in the T47D human breast carcinoma cell line. Among the synthesized compounds, 36 (IC(50) = 0.12 mu M) and 38 (IC(50) = 0.06 mu M), bearing a five-membered heterocycle, showed potent PR antagonist activity. Competitive binding assay showed that compounds 8 and 34 have potent PR binding affinity. The fluorescence of compound 8 was dependent on the solvent properties and was increased in the presence of PR ligand binding domain. This property might be applicable to the development of fluorescence probes for studies on PR.
