Site-Specific Polymer Attachment to HR2 Peptide Fusion Inhibitors against HIV-1 Decreases Binding Association Rates and Dissociation Rates Rather Than Binding Affinity

Harm-Anton Klok, Maarten Danial, Frederik Roman Wurm

A popular strategy for overcoming the limited plasma half-life of peptide heptad repeat 2 (HR2) fusion inhibitors against HIV-1 is conjugation with biocompatible polymers such as poly(ethylene glycol) (PEG). However, despite improved resistance to proteoly ...

Polymeric Anti-HIV Therapeutics

Harm-Anton Klok, Maarten Danial

The scope of this review is to highlight the application of polymer therapeutics in an effort to curb the transmission and infection of the human immunodeficiency virus (HIV). Following a description of the HIV life cycle, the use of approved antiretrovira ...

Site-Specific PEGylation of HR2 Peptides: Effects of PEG Conjugation Position and Chain Length on HIV-1 Membrane Fusion Inhibition and Proteolytic Degradation

Harm-Anton Klok, Maarten Danial

Peptides derived from the HR1 or HR2 regions of the HIV-1 envelope glycoprotein gp41 have been shown to be effective inhibitors to prevent virus-host cell membrane fusion. These peptide drugs, however, suffer from relatively short plasma half-lives and are ...

Polyvalent Side Chain Peptide-Synthetic Polymer Conjugates as HIV-1 Entry Inhibitors

Harm-Anton Klok, Maarten Danial

This report describes the synthesis and properties of a series of polyvalent side chain peptide synthetic polymer conjugates designed to block the CD4 binding site on gp120 and inhibit HIV-1 entry into a host cell. The peptide sequences in the conjugates a ...

Voltammetric Detection of Hg2+ Using Peptide-Functionalized Polymer Brushes

Harm-Anton Klok, Maarten Danial

Polymer brushes grafted by surface-initiated atom transfer radical polymerization (SI-ATRP) from the surface of Ir-based microelectrode arrays are explored as a platform for the fabrication of sensory coatings for the voltammetric detection of Hg2+. The po ...

Sequentially Modified, Polymer-Stabilized Gold Nanoparticle Libraries: Convergent Synthesis and Aggregation Behavior

Harm-Anton Klok, Maarten Danial, Matthew Gibson

This manuscript describes a versatile, yet experimentally facile, method for producing libraries of polymer coated (core-shell type) gold nanoparticles. The synthetic principle relies on two, sequential postmodification reactions, which ensures homogeneity ...

Side-Chain Peptide-Synthetic Polymer Conjugates via Tandem "Ester-Amide/Thiol-Ene" Post-Polymerization Modification of Poly(pentafluorophenyl methacrylate) Obtained Using ATRP

Harm-Anton Klok, Maarten Danial, Matthew Gibson

Herein the concept of tandem postpolymerization modification as a versatile route to synthesize well-defined, highly functionalized polymers is introduced. Poly(pentafluorophenyl methacrylate) obtained by atom transfer radical polymerization was first modi ...

Combating HIV Type 1 with Peptide - Synthetic Polymer Conjugates

Maarten Danial

Polymer therapeutics is a class of (bio)hybrid materials that include a plethora of biologically active (synthetic) macromolecules that either consist of polymeric drugs, drug-polymer conjugates, peptide/protein-polymer conjugates or of drug, peptide or pr ...

Coiled coils: attractive protein folding motifs for the fabrication of self-assembled, responsive and bioactive materials

Harm-Anton Klok, Maarten Danial

The coiled coil is a superhelical protein structural motif that consists of two or more alpha-helical peptides that are wrapped around each other in superhelical fashion. Coiled coils are amongst the most ubiquitous folding motifs found in proteins and hav ...

Complex coacervate core micelles with a lysozyme-modified corona

Harm-Anton Klok, Maarten Danial

This paper describes the preparation, characterization, and enzymatic activity of complex coacervate core micelles (C3Ms) composed of poly (acrylic acid) (PAA) and poly (N- methyl-2- vinyl pyridinium iodide)-b-poly (ethylene oxide) (PQ2VP-PEO) to which the ...
