Insights

Novel biosurfactant nanoparticles show potent anticancer effects against breast cancer cells. Folic acid targeting enhances drug delivery and cytotoxicity, offering a promising alternative to chemotherapy.

Area of Science:

  • Biotechnology
  • Nanomedicine
  • Cancer Research

Background:

  • Traditional chemotherapy faces limitations due to side effects.
  • Natural product-derived anticancer agents are being explored as alternatives.
  • Previous studies identified a novel biosurfactant from Candida parapsilosis with anticancer properties.

Purpose of the Study:

  • To synthesize and evaluate the cytotoxicity of polymeric nanoparticles encapsulating a novel biosurfactant against breast cancer cells.
  • To investigate the role of folic acid (FA) as a targeting ligand for enhanced delivery and efficacy.
  • To assess the controlled release and apoptotic effects of the targeted nanoparticles.

Main Methods:

  • Synthesis of polylactic acid-poly(ethylene glycol) (PLA-PEG) copolymer nanoparticles encapsulating the biosurfactant using a double emulsion solvent evaporation method.
  • Functionalization of nanoparticles with folic acid (FA) for targeted delivery.
  • Evaluation of encapsulation efficiency, drug release kinetics (Fickian diffusion), and cellular uptake in MDA-MB-231 breast cancer cells.
  • Assessment of cytotoxicity and induction of apoptosis.

Main Results:

  • High encapsulation efficiency (84.9%) of the biosurfactant within PLA-PEG nanoparticles was achieved.
  • Controlled release of the biosurfactant from nanoparticles followed Fickian diffusion kinetics.
  • Folic acid-targeted nanoparticles demonstrated enhanced cellular uptake and cytotoxicity in MDA-MB-231 cells compared to non-targeted nanoparticles.
  • The nanoparticles effectively induced apoptosis in cancer cells.

Conclusions:

  • PLA-PEG copolymer nanoparticles provide an effective system for controlled delivery of the novel biosurfactant.
  • Folic acid-mediated targeting significantly improves the anticancer efficacy of the biosurfactant-loaded nanoparticles.
  • These targeted nanoparticles represent a promising, potentially less toxic, alternative for breast cancer therapy.
