The synthesis and in vitro and in vivo anti-breast and anti-prostate cancers activities of novel C-4 heteroaryl 13-cis retinamides that modulate Mnk-eIF4E and AR signaling are discussed. In both breast and prostate cancer cell lines, these compounds induce Mnk1/2 degradation to substantially suppress eIF4E phosphorylation. In prostate cancer cells, the compounds induce degradation of both full-length androgen receptor (fAR) and splice variant AR (AR-V7) to inhibit AR transcriptional activity. The consequences of these multiple activities resulted in inhibition of cell growth and migration and induction of apoptosis. Finally and importantly, the compounds demonstrate strong in vitro and in vivo anti-breast and anti-prostate cancer activities, with no apparent host toxicities.
本文讨论了能调节 Mnk-eIF4E 和 AR 信号转导的新型 C-4 杂芳基 13-顺式视黄酸的合成、体外和体内抗乳腺癌和抗前列腺癌活性。在乳腺癌和前列腺癌细胞系中,这些化合物都能诱导 Mnk1/2 降解,从而大幅抑制 eIF4E 磷酸化。在前列腺癌细胞中,这些化合物可诱导全长雄激素受体(fAR)和剪接变体 AR(AR-V7)降解,从而抑制 AR 的转录活性。这些多重活性的结果抑制了细胞的生长和迁移,并诱导了细胞凋亡。最后,也是最重要的一点是,这些化合物在体外和体内都表现出很强的抗乳腺癌和抗前列腺癌活性,而且没有明显的宿主毒性。
