Special Issue Information

Dear Colleagues,

Serum albumins, which are found in mammalian blood, bind to various ligands and transport them throughout the body. They also serve as a carrier for steroids, fatty acids, and thyroid hormones. Albumin is known to accumulate in malignant and inflamed tissue due to defective blood vessels combined with a defective lymphatic drainage system. Albumins are intrinsically less immunogenic, biocompatible, and biodegradable. They exhibit a lower cytotoxicity than other nanoparticles of proteins and polymers from natural or synthetic origin. Their charged moieties offer numerous possibilities for surface modification and interaction with various therapeutic molecules. Albumin can be considered an ideal delivery system designed by nature. Albumin nanoparticles, on the other hand, provide additional functionalities such as increased drug load, delivery tuning, improved stability and bioavailability of the system, modulation of active and passive targeting, and superior pharmacokinetic/pharmacodynamic profiles. This Special Issue will cover the following subjects:

  • New synthetic routes based on sustainable and green nanotechnology;
  • Covalent and non-covalent drug attachment;
  • Drug load;
  • Release profile, burst release;
  • New applications of albumins and proteins nanoparticles;
  • Stability and bioavailability;
  • Applications in cancer therapy and diagnosis;
  • Modulation of drug resistance;
  • Modulation of circulation time;
  • Toxicity, immunogenicity.

Carvedilol, an anti-hypertensive medication commonly prescribed by healthcare providers, falls under the BCS class II category due to its low-solubility and high-permeability characteristics, resulting in limited dissolution and low absorption when taken orally. Herein, carvedilol was entrapped into bovine serum albumin (BSA)-based nanoparticles using the desolvation method to obtain a controlled release profile. Carvedilol-BSA nanoparticles were prepared and optimized using 32 factorial design. The nanoparticles were characterized for their particle size (Y1), entrapment efficiency (Y2), and time to release 50% of carvedilol (Y3). The optimized formulation was assessed for its in vitro and in vivo performance by solid-state, microscopical, and pharmacokinetic evaluations. The factorial design showed that an increment of BSA concentration demonstrated a significant positive effect on Y1 and Y2 responses with a negative effect on Y3 response. Meanwhile, the carvedilol percentage in BSA nanoparticles represented its obvious positive impact on both Y1 and Y3 responses, along with a negative impact on Y2 response. The optimized nanoformulation entailed BSA at a concentration of 0.5%, whereas the carvedilol percentage was 6%. The DSC thermograms indicated the amorphization of carvedilol inside the nanoparticles, which confirmed its entrapment into the BSA structure. The plasma concentrations of carvedilol released were observable from optimized nanoparticles up to 72 h subsequent to their injection into rats, revealing their longer in vivo circulation time compared to pure carvedilol suspension. This study offers new insight into the significance of BSA-based nanoparticles in sustaining the release of carvedilol and presents a potential value-added in the remediation of hypertension.
