The worldwide health burden of colorectal cancer is still substantial, and traditional chemotherapeutic drugs sometimes have poor selectivity, which can result in systemic toxicity and unfavorable side effects. For colon-specific medication delivery, bioengineered carbohydrate polymers have shown promise as carriers. They may enhance treatment effectiveness while minimizing systemic exposure and associated side effects. The unique properties of these manufactured or naturally occurring biopolymers, such as hyaluronic acid, chitosan, alginate, and pectin, enable targeted medicine release. These qualities can be changed to meet the physiological needs of the colon. In the context of colorectal cancer therapy, this article provides a comprehensive overview of current developments and prospective future directions in the field of bioengineered carbohydrate polymer synthesis for colon-specific drug delivery. We discuss numerous techniques for achieving colon-targeted drug release, including enzyme-sensitive polymers, pH-responsive devices, and microbiota-activated processes. To increase tumor selectivity and cellular uptake, we also examine the inclusion of active targeting approaches, such as conjugating specific ligands. Furthermore, we discuss the potential of combination treatment strategies, which use the coadministration of numerous therapeutic medications to target multiple pathways implicated in cancer growth and address drug resistance mechanisms. We address recent biomimetic advances that potentially improve the biocompatibility, cellular uptake, and tumor penetration of carbohydrate polymer-based nanocarriers. These methods involve protein corona engineering and cell membrane coating. Furthermore, we look at the possibility of intelligent and sensitive systems that may adjust their behaviors in response to certain inputs or feedback loops, allowing for precise and regulated drug distribution.
结直肠癌的全球健康负担仍然很大,传统的化疗药物有时选择性差,会导致全身毒性和不良的副作用。对于结肠特异性药物递送,生物工程碳水化合物聚合物已显示出作为载体的潜力。它们可以提高治疗效果,同时最大限度地减少全身暴露和相关的副作用。这些制造或天然存在的生物聚合物(如透明质酸、壳聚糖、海藻酸盐和果胶)具有独特的性质,可以实现靶向药物释放。这些特性可以根据结肠的生理需求进行改变。在结直肠癌治疗的背景下,本文全面概述了生物工程碳水化合物聚合物合成用于结肠特异性药物递送领域的最新进展和未来展望。我们讨论了实现结肠靶向药物释放的多种技术,包括酶敏感聚合物、pH 响应装置和微生物群激活过程。为了提高肿瘤选择性和细胞摄取率,我们还研究了包含主动靶向方法的可能性,例如结合特定配体。此外,我们还讨论了联合治疗策略的潜力,该策略通过联合使用多种治疗药物来靶向癌症生长中涉及的多个途径,并解决药物耐药机制。我们讨论了最近的仿生学进展,这些进展有可能提高基于碳水化合物聚合物的纳米载体的生物相容性、细胞摄取和肿瘤穿透性。这些方法涉及蛋白质冠工程和细胞膜涂层。此外,我们还研究了智能和敏感系统的可能性,这些系统可以根据某些输入或反馈回路来调整它们的行为,从而实现精确和调节的药物分布。
