Unlocking the synthetic approaches and clinical application of approved small-molecule drugs for gastrointestinal cancer treatment: A comprehensive exploration.

Gastrointestinal (GI) cancers encompass a group of malignancies affecting the digestive system, including the stomach, esophagus, liver, colon, rectum and pancreas. These cancers represent a significant global health burden, necessitating effective treatment strategies. Small-molecule drugs have emerged as crucial therapeutic options in the fight against GI cancers due to their oral bioavailability, targeted mechanisms of action, and well-established safety profiles. The review then elucidates the clinical applications and synthetic methods of clinically approved small-molecule drugs for the treatment of GI cancer, shedding light on their mechanisms of action and their potential in mitigating GI cancer progression. The review also discusses future prospects and the evolving landscape of small-molecule drug development in GI oncology, highlighting the potential for personalized medicine. In summary, this review provides valuable insights into cutting-edge strategies for harnessing clinically approved small-molecule drugs to combat GI cancer effectively.
