尽管患病率低,胰腺癌(PC)是最致命的癌症之一,通常在早期阶段表现为沉默,在晚期阶段预后极差,通常与高度转移有关。在追求创新的治疗方法方面已经做出了许多努力,从寻找新的细胞毒性药物和其他生物活性化合物,发展更有针对性的方法,包括改进的药物输送装置。海洋生物技术通过提供源自不同生物的新化学线索和材料,为这一追求做出了贡献。在这次审查中,解决了PC的海洋生物发现问题,特别是关于海洋无脊椎动物(即海绵,软体动物,和苔藓虫),海藻,真菌,和细菌。此外,开发基于海洋来源化合物的生物材料,特别是壳聚糖,岩藻聚糖,和藻酸盐,用于生产先进的癌症疗法,也讨论了。强调了药物递送在新的癌症治疗中可以发挥的关键作用,因为治疗结果需要改善,以给患者带来进一步的希望。
Despite its low prevalence, pancreatic cancer (PC) is one of the deadliest, typically characterised as silent in early stages and with a dramatically poor prognosis when in its advanced stages, commonly associated with a high degree of metastasis. Many efforts have been made in pursuing innovative therapeutical approaches, from the search for new cytotoxic drugs and other bioactive compounds, to the development of more targeted approaches, including improved drug delivery devices. Marine biotechnology has been contributing to this quest by providing new chemical leads and materials originating from different organisms. In this review, marine
biodiscovery for PC is addressed, particularly regarding marine invertebrates (namely sponges, molluscs, and bryozoans), seaweeds, fungi, and bacteria. In addition, the development of biomaterials based on marine-originating compounds, particularly chitosan, fucoidan, and alginate, for the production of advanced cancer therapies, is also discussed. The key role that drug delivery can play in new cancer treatments is highlighted, as therapeutical outcomes need to be improved to give further hope to patients.
