In this study, we utilized <i>Ganoderma lucidum</i> polysaccharides (GLP) as a macromolecular carrier to synthesize polysaccharide drug conjugates by forming ester bonds with 5-fluorouracil (5-FU) derivatives (5-FUAC). This not only improves the solubility and stability of 5-FU but also enhances its targeted delivery to tumor tissues, potentially reducing systemic toxicity. Utilizing <i>Ganoderma lucidum</i> polysaccharides (GLP) as a macromolecular carrier, we successfully synthesized GLP-5-FU conjugates by forming ester bonds with 5-fluorouracil derivatives (5-FUAC). These conjugates were then characterized using spectrum analysis technologies. The drug loading capacities of 5-FU in the GLP-5-FU conjugates were found to be approximately 4.7%. Morphological observations revealed that the GLP-5-FU conjugates had a regular spherical shape. In terms of drug release, 5-FU was found to be released faster at pH 6.8 compared to pH 7.4. To investigate the dynamic viscoelastic behavior of GLP and GLP-5-FU conjugates in water, dynamic rheology analysis was conducted. In terms of cytotoxicity, the GLP-5-FU conjugates exhibited greater inhibition of proliferation compared to 5-FU and GLP alone in HeLa, 786-O, and SKOV3 cells.

Prior to release studies, drug solubilization efficiency and micelle size were evaluated using UV–Visible spectroscopy and Dynamic Light Scattering, both in the presence and absence of NaCl. Among the tested formulations, Pluronic^® P84 demonstrated superior solubilization for both drugs, enhancing IRB and LAM solubility by ~ 3.6/2.3 times compared to F108 and ~ 1.6/1.9 times compared to T1307 in 1 M NaCl.
