Special Issue Information

Dear Colleagues,

The Centers for Disease Control and Prevention and the World Health Organization (WHO) have recognized non-comunicable diseases, such as cancer and cardiovascular disease, as major global public health burdens and the leading causes of death both nationally and internationally.

Strategies for preventing and controlling the leading causes of non-communicable disease-related deaths worldwide are needed. Despite recent advances in the management of these diseases, pharmaceutical treatment remains suboptimal because of poor pharmacokinetics and the high toxicity of some therapeutic compounds.

In the last few years, a new era of biomaterials has grown, and become one of the most influential and innovative hot topics of research. Biomaterial Science ushers a completely new technological paradigm favoring the development of novel drug delivery applications that are transforming the healthcare sector. The design and development of multifunctional and biomimetic drug delivery systems, compatible with human physiology, are crucial to boosting life expectancy and increasing quality of life.

There has been a long-standing interest in understanding and utilizing different solutions of drug delivery to tackle challenging issues of precision medicine.

Considerable efforts in improving drug efficacy, pharmacokinetics, and biodistribution of therapeutic agents through site-specific, target-oriented delivery and controlled drug release, thus reducing most of all side adverse effects, have been achieved through drug delivery systems.

With a focus on- but not limited to- cancer and cardiovascular diseases, in this special issue will be an overview of the major challenges and fundamental discoveries in drug delivery systems, whose structure, properties, or function mimic those of natural materials or living matter. Particular attention will be devoted to the progress which has been made in technology and methods for the synthesis and self-assembly of drug delivery systems and in the design of materials for the delivery of therapeutics.

Original research and reviews with a strong focus on newer and challenging products are welcome, with particular emphasis on – but not limited to – biomimetic, biocompatible, and biodegradable drug delivery systems with tunable drug-release profiles, able to respond to environmental stimuli and control the spatiotemporal presentation of a therapeutic, engineered drug delivery systems of various sizes, shapes, compositions and physicochemical properties and functionalized biosensor drug delivery systems with theranostic feature.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

They comprise acid-labile P(O)-O-C and C(O)-O-C bonds, the cleavage of which depends on the pH of the medium. The structure of these copolymers was characterized by 1H, [...] Read more.
pH-sensitive amphiphilic diblock polyphosphoesters containing lactic acid units were synthesized by multistep one-pot polycondensation reactions. They comprise acid-labile P(O)-O-C and C(O)-O-C bonds, the cleavage of which depends on the pH of the medium. The structure of these copolymers was characterized by 1H, 13C {H}, 31P NMR, and size exclusion chromatography (SEC). The newly synthesized polymers self-assembled into the micellar structure in an aqueous solution. The effects of the molecular weight of the copolymer and the length of the hydrophobic chain on micelle formation and stabilityand micelle size were studied via dynamic light scattering (DLS). Drug loading and encapsulation efficiency tests using doxorubicin revealed that hydrophobic drugs can be delivered by copolymers. It was established that the molecular weight of the copolymer, length of the hydrophobic chain and content of lactate units affects the size of the micelles, drug loading, and efficiency of encapsulation. A copolymer with 10.7% lactate content has drug loading (3.2 ± 0.3) and efficiency of encapsulation (57.4 ± 3.2), compared to the same copolymer with 41.8% lactate content (1.63%) and (45.8%), respectively. It was demonstrated that the poly[alkylpoly(ethylene glycol) phosphate-b-alkylpoly(ethylene glycol)lactate phosphate] DOX system has a pH-sensitive response capability in the result in which DOX was selectively accumulated into the tumor, where pH is acidic. The results obtained indicate that amphiphilic diblock polyphosphoesters have potential as drug carriers. Full article
