Supplementary table - Alpha-fetoprotein mediated targeting of polymeric nanoparticles to treat solid tumors nnm-2022-0097

Background: Serious side effects caused by paclitaxel formulation, containing toxic solubilizer
Cremophor R ? EL, and its nonspecific accumulation greatly limit clinical paclitaxel application. Aim: To
design paclitaxel-loaded copolymer of lactic and glycolic acids nanoparticles decorated with alphafetoprotein
third domain (rAFP3d-NP) to increase paclitaxel safety profile. Methods: rAFP3d-NP was
obtained via carbodiimide technique. Results: The particles were characterized with high paclitaxel
loading content of 5% and size of 280 nm. rAFP3d-NP revealed biphasic profile with 67% release
of paclitaxel during 220 h. Increased area under the curveinf and mean residence time values after
rAFP3d-NP administration confirmed prolonged blood circulation compared with paclitaxel. rAFP3d-NP
demonstrated significant tumor growth inhibition at 4T1 and SKOV-3 models. Conclusion: rAFP3d-NP is
a promising delivery system for paclitaxel and can be applied similarly for delivery of other hydrophobic
drugs.
