Special Issue Information

Dear Colleagues,

Recent achievements in peptide and protein synthesis and large-scale production have revealed the high potential of these compounds as selective and efficient drugs for the treatment of a number of diseases. Currently, proteins and peptides are widely considered as prospective biopharmaceutics or vaccines and many of them are already available in clinics as oral, intravenous, subcutaneous, transdermal, and intranasal formulations. In spite of the many advantages of peptides and proteins as drugs, their wide application is limited because of some crucial obstacles. Among these, opsonization and proteolytic degradation severely affect their therapeutic efficiency. In turn, more frequent administration may cause many complications and undesirable side-effects. Moreover, the intracellular action of some peptide and protein drugs can be limited because of their poor penetration into the cell. The abovementioned problems can be overcome by different approaches, such as conjugation of peptides/proteins with polymers, encapsulation/entrapment of biopharmaceutics into polymer particles, as well as application of special systems or/and vectors for intracellular delivery.

As Guest Editors, we invite researchers to submit to this Special Issue their valuable results and findings focused on conjugation, encapsulation, entrapment, preparation of novel formulations, or other modifications to enhance stability of peptides/proteins and improve their therapeutic efficacy or intracellular delivery. Articles prepared as research papers, reviews, or short communications are welcomed for publication.

Hydrophobic ion pairing (HIP) complexation was found to be an efficient approach in modulating the release and enhancing the stability and encapsulation of hydrophilic macromolecules such as proteins in hydrophobic nano/microcarriers. The present work strives to develop and optimize the preparation of the HIP complex of the antimicrobial enzyme lysozyme (LYZ) with the ion-pairing agent (IPA) sodium dodecyl sulphate (SDS) relying on the quality-by-design (QbD) approach. The quality target product profile (QTPP) includes the achievement of maximal lipophilicity in a reversible manner to enable the maintenance of biological activity. The related critical quality attributes (CQAs) were defined as complexation efficacy, complex stability, enzyme recovery and activity. Three risk assessment (RA) tools were used to identify and rank the critical process parameters (CPPs) and critical material attributes (CMAs). From this assessment, the pH of the medium, LYZ:SDS molar ratio and drying conditions were determined as high-risk factors that need to be investigated. To the best of our knowledge, for the first time, electrostatic titration was used as a smart approach to determine the optimum molar ratio at different pH values. Based on the predefined CQAs, pH 8 with an LYZ/SDS molar ratio of 1:8 was found to be the optimal condition for complexation efficiency and recovery (%) of a biologically active enzyme. A cost-effective drying process based on a ventilated oven was developed, which resulted in complex qualities comparable to those obtained by the commonly used freeze-drying method. In a nutshell, the optimum conditions for the preparation of the LYZ/SDS HIP complex were efficiently facilitated by the rational application of QbD principles and the utilization of efficient electrostatic titration and ventilated oven-drying methods.
