5-Fluorouracil (5-FU) is a widely used chemotherapeutic agent primarily employed in the treatment of colorectal cancer, among other types of cancer. It functions as an antimetabolite, interfering with the synthesis of DNA and RNA by inhibiting the enzyme thymidylate synthase, which is crucial for DNA replication. The gene location and structure of 5-FU are not directly applicable as it is a synthetic compound, but its mechanism of action involves the incorporation into RNA and DNA, disrupting normal cellular processes. Despite its efficacy, 5-FU is associated with challenges such as drug resistance, low bioavailability, and rapid metabolism, prompting the development of innovative delivery systems to enhance its therapeutic effects. Research continues to explore strategies to overcome these limitations, including nano-delivery systems and combination therapies to improve its anticancer activity.
