Naturally occurring agents have always been appreciated for their medicinal value for both their chemopreventive and therapeutic effects against cancer. In fact, the majority of the drugs we use today, including the anti-cancer agents, were originally derived from natural compounds, either in their native form or modified to enhance their bioavailability or specificity. It is believed that for maximum effectiveness, it will useful to design novel target-based agents for chemoprevention as well as the treatment of cancer. Recent studies have shown that the serine/threonine kinase polo-like kinase (Plk) 1 is widely overexpressed in a variety of cancers and is being increasingly appreciated as a target for cancer management. Additionally, several chemopreventive agents have been shown to inhibit Plk1 in cancer cells. In this review, we will discuss if Plk1 could also be a target for designing novel strategies for cancer chemoprevention.
天然产物因其对癌症的化学预防和治疗作用而一直受到重视。事实上,我们今天使用的大多数药物,包括抗癌药物,最初都是从天然化合物中提取的,无论是以其天然形式还是经过修饰以提高其生物利用度或特异性。人们认为,为了达到最大的效果,设计针对化学预防和癌症治疗的新型基于靶点的药物将是有用的。最近的研究表明,丝氨酸/苏氨酸激酶 polo 样激酶(Plk)1 在多种癌症中广泛过表达,并且作为癌症管理的靶点越来越受到重视。此外,已经有几种化学预防剂被证明可以抑制癌细胞中的 Plk1。在这篇综述中,我们将讨论 Plk1 是否也可以作为设计癌症化学预防新策略的靶点。
