抗癌化疗药物开发方面的挑战仍然存在,特别是在不良反应和耐药性发展方面,这突出表明需要具有良好安全性的新药。天然产物已被证明是开发的沃土,从结构复杂的天然产物中开发抗癌药物是有希望的。不幸的是,这种方法往往受到低分离产率和有限的信息,从初步的细胞为基础的测定。本文报道了一系列低丰度的Isodondonditerpenoids(从Isodon属植物中分离得到的天然产物,具有超过1000个成员,是治疗炎症和癌症的著名民间药物),包括毛萼素B、新毛蕊花素L和旱生花素I的简明和可扩展的合成。这些可扩展的合成使得能够对天然产物进行多层次的生物评价,其中我们将neolaxiflorin L确定为有希望的抗癌候选药物。
Challenges in the development of anti-cancer chemotherapeutics continue to exist, particularly with respect to adverse effects and development of resistance, underlining the need for novel drugs with good safety profiles. Natural products have proven to be a fertile ground for exploitation, and development of anti-cancer drugs from structurally complex natural products holds promise. Unfortunately, this approach is often hindered by low isolation yields and limited information from preliminary cell-based assays. Here we report a concise and scalable synthesis of a series of low-abundanceIsodonditerpenoids (a large class of natural products with over 1000 members isolated from the herbs of genusIsodon, which are well-known folk medicines for the treatment of inflammation and cancer), including eriocalyxin B, neolaxiflorin L and xerophilusin I. These scalable syntheses enable multilevel bio-evaluation of the natural products, in which we identify neolaxiflorin L as a promising anti-cancer drug candidate.
