Van Guyse JFR, Bernhard Y, Podevyn A, Hoogenboom R. Non-activated Esters as Reactive Handles in Direct Post-Polymerization Modification. Angew Chem Int Ed Engl 2023; 62:e202303841.

Abstract
Non-activated esters are prominently featured functional groups in polymer science, as ester functional monomers display great structural diversity and excellent compatibility with a wide range of polymerization mechanisms. Yet, their direct use as a reactive handle in post-polymerization modification has been typically avoided due to their low reactivity, which impairs the quantitative conversion typically desired in post-polymerization modification reactions. While activated ester approaches are a well-established alternative, the modification of non-activated esters remains a synthetic and economically valuable opportunity. In this review, we discuss past and recent efforts in the utilization of non-activated ester groups as a reactive handle to facilitate transesterification and aminolysis/amidation reactions, and the potential of the developed methodologies in the context of macromolecular engineering.

Abstract
In this study, we prepared poly(acryloyl hydrazide) (PAH)-grafted cellulose nanocrystal (CNC-PAH) particles via the atom transfer radical polymerization method for application to Cr(VI) adsorption. The closely-packed PAH chains grafted on the cellulose nanocrystal (CNC) surface provide a high density of amine groups that can adsorb Cr(VI) through strong electrostatic, hydrogen bonding and chelating interactions. CNC-PAH exhibited the optimum Cr(VI) adsorption capacity at the solution pH = 3, where its electrostatic attraction with Cr(VI) was maximized. Cr(VI) was chemisorbed in CNC-PAH by following the Langmuir isotherm mechanism (homogeneous monolayer adsorption). The Cr(VI) adsorption kinetics of CNC-PAH was controlled predominantly by intra-particle diffusion resistance imparted by the PAH shell layer. Thermodynamic analysis revealed that Cr(VI) adsorption of CNC-PAH is a spontaneous and endothermic process. Importantly, CNC-PAH grafted with the higher Mw (∼50 kg mol-1) PAH exhibited a rapid Cr(VI) adsorption rate and remarkably high Cr(VI) adsorption capacity (∼457.6 mg g-1 at 298.15 K), exceeding those of previously reported adsorbents owing to its numerous Cr(VI)-adsorptive amine groups provided by the closely-packed grafted PAH polymers. Furthermore, CNC-PAH showed excellent reusability to maintain its high adsorption ability during repeated adsorption-desorption cycles owing to the covalently binding nature of the PAH polymers.

Abstract
Despite the powerful nature of the aza-Michael reaction for generating C-N linkages and bioactive moieties, the bis-Michael addition of 1° amines remains ineffective for the synthesis of functional, step-growth polymers due to the drastic reduction in reactivity of the resulting 2° amine mono-addition adduct. In this study, a wide range of commercial hydrazides are shown to effectively undergo the bis-Michael reaction with divinyl sulfone (DVS) and 1,6-hexanediol diacrylate (HDA) under catalyst-free, thermal conditions to afford moderate to high molecular weight polymers with M n = 3.8-34.5 kg mol-1. The hydrazide-Michael reactions exhibit two distinctive, conversion-dependent kinetic regimes that are 2nd-order overall, in contrast to the 3rd-order nature of amines previously reported. The mono-addition rate constant was found to be 37-fold greater than that of the bis-addition at 80 °C for the reaction between benzhydrazide and DVS. A significant majority (12 of 15) of the hydrazide derivatives used here show excellent bis-Michael reactivity and achieve >97% conversions after 5 days. This behavior is consistent with calculations that show minimal variance of electron density on the N-nucleophile among the derivatives studied. Reactivity differences between hydrazides and hexylamine are also explored. Overall, the difference in reactivity between hydrazides and amines is attributed to the adjacent nitrogen atom in hydrazides that acts as an efficient hydrogen-bond donor that facilitates intramolecular proton-transfer following the formation of the zwitterion intermediate. This effect not only activates the Michael acceptor but also coordinates with additional Michael acceptors to form an intermolecular reactant complex.

Abstract
The combinatorial polymer library approach has been proven to be effective for the optimization of therapeutic delivery systems. The library of polymers with chemical diversity has been synthesized by (i) polymerization of functionalized monomers or (ii) post-polymerization modification of reactive polymers. Most scientists have followed the first approach so far, and the second method has emerged as a versatile approach for combinatorial biomaterials discovery. This review focuses on the second approach, especially discussing the post-modifications that employ reactive polymers as templates for combinatorial synthesis of a library of functional polymers with distinct structural diversity or a combination of different functionalities. In this way, the functional polymers have a consistent chain length and distribution, which allows for systematic optimization of therapeutic delivery polymers for the efficient delivery of genes, small-molecule drugs, and protein therapeutics. In this review, the modification of representative reactive polymers for the delivery of different therapeutic payloads are summarized. The recent advances in rational design and optimization of therapeutic delivery systems based on reactive polymers are highlighted. This review ends with a summary of the current achievements and the prospect on future directions in applying the approach of post-polymerization modification of polymers to accelerate the development of therapeutic delivery systems. STATEMENT OF SIGNIFICANCE A strategy to rationally design and systematically optimize polymers for the efficient delivery of specific therapeutics is highly needed. The combinatorial polymer library approach could be an effective way to this end. The post-polymerization modification of reactive polymer precursors is applicable for the combinatorial synthesis of a library of functional polymers with distinct structural diversity across a consistent degree of polymerization. This allows for parallel comparison and systematic evaluation/optimization of functional polymers for efficient therapeutic delivery. This review summarizes the key elements of this combinatorial polymer synthesis approach realized by post-polymerization modification of reactive polymer precursors towards the development and identification of optimal polymers for the efficient delivery of therapeutic agents.

Abstract
A series of injectable hydrogels was prepared by cross-linking oxidized carboxymethyl cellulose (oxi-CMC) with polyacryloyl hydrazide (PAH) via a Schiff base reaction under physiological conditions. The hydrogels exhibited superior performance such as appropriate rheology properties, high swelling ratio, and low degradation rate. In phosphate buffer solution (PBS, pH 7.4) at 37°C, the swelling ratio of the hydrogels ranged from 19 to 28 after 7 h, the degradation percentage of the oxi-CMC6/PAH3 hydrogel was ~47 % after 20 days. Using bovine serum albumin (BSA) as a model protein drug, the results of in vitro drug release studies demonstrated that the sustained release of BSA could be cooperatively controlled through drug diffusion and hydrogel degradation in PBS (pH 7.4) at 37°C, and the cumulative release percentage of BSA from a drug-loaded oxi-CMC6/PAH3 hydrogel was ~88 % after 8 days. The results signified that oxi-CMC6/PAH3 hydrogel could be potentially applied in the fields of drug delivery vehicles, tissue engineering, and cell encapsulation materials.

Abstract
In this work, we report a convenient and versatile strategy for surface-grafted glycopolymer constructs with the goal of surface modification that controls the chemical presentation and grafting density of carbohydrate side chains. This approach employs a difunctional hydrazine linker, chemically modified to an active ester containing poly(pentafluorophenyl acrylate) grafted scaffold, to conjugate a variety of saccharides through the reducing end. The successive conjugation steps are carried out under mild conditions and yield high surface densities of sugars, as high as 4.8 nmol·cm-2, capable of multivalency, with an intact structure and retained bioactivity. We also demonstrate that this glycosylated surface can bind specific lectins according to the structure of its pendant carbohydrate. To demonstrate bioactivity, this surface platform is used to study the binding events of a human respiratory tract pathogen, Mycoplasma pneumoniae, on surfaces conjugated with sialylated sugars.

Abstract
The efficiency of a fluorescence sensing device based on metal-enhanced fluorescence (MEF) is dependent on the optimization of interaction between the fluorophore and the metal nanoparticle (NP). Herewith, ultrasensitive and selective turn-on sensing of Au3+ is achieved by using a suitable combination of fluorophore and metal NP system through sequential MEF effect. Dansyl hydrazide-tagged Ag NPs in the polyacryloyl hydrazide cavity are utilized to sense the picomolar concentration of Au3+ in aqueous media. We demonstrated that the selective Au3+ sensing is due to the selective deposition of Au on the Ag NP surface over the 16 other metal ions studied. The sensitivity is assigned to the strong overlapping of the emission band of the fluorophore with the surface plasmon band of the Au and improvement of fluorescence signal through successive MEF by Ag and Au colloids. The sensing is associated with a fivefold increase in fluorescence intensity and appearance of violet color of the solution. These luminescent Ag-Au bimetallic NPs may be utilized to trace cancer cells in biological systems and for cell imaging applications.

Abstract
Here we present the synthesis of poly(acryloyl hydrazide), a versatile scaffold for the preparation of functional polymers, and its post-polymerisation modification using a wide range of conditions.
Here we present the synthesis and post-polymerisation modification of poly(acryloyl hydrazide), a versatile scaffold for the preparation of functional polymers: poly(acryloyl hydrazide) was prepared from commercially available starting materials in a three step synthesis on a large scale, in good yields and high purity. Our synthetic approach included the synthesis of a Boc-protected acryloyl hydrazide, the preparation of polymers via RAFT polymerisation and the deprotection of the corresponding Boc-protected poly(acryloyl hydrazide). Post-polymerisation modification of poly(acryloyl hydrazide) was then demonstrated using a range of conditions for both hydrophilic and hydrophobic aldehydes. These experiments demonstrate the potential of poly(acryloyl hydrazide) as a scaffold in the synthesis of functional polymers, in particular those applications where in situ screening of the activity of the functionalised polymers may be required (e.g. biological applications).

Abstract
Herewith, we report a facile synthesis of pH responsive polyacryloyl hydrazide (PAH) capped silver (Ag) or gold (Au) nanogels for anticancer therapeutic applications. A cost-effective instant synthesis of PAH-Ag or PAH-Au nanoparticles (NPs) possessing controllable particle diameter and narrow size distribution was accomplished by adding AgNO3 or AuCl to the aqueous solution of PAH under ambient conditions without using any additional reagent. PAH possessing carbonyl hydrazide pendant functionality served as both reducing and capping agent to produce and stabilize the NPs. The stability analysis by UV-vis, dynamic light scattering, and transmission electron microscopy techniques suggested that these NPs may be stored in a refrigerator for at least up to 2 weeks with negligible change in conformation. The average hydrodynamic size of PAH-Ag NPs synthesized using 0.2 mmol/L AgNO3 changed from 122 to 226 nm on changing the pH of the medium from 5.4 to 7.4, which is a characteristic property of pH responsive nanogel. Camptothecin (CPT) with adequate loading efficiency (6.3%) was encapsulated in the PAH-Ag nanogels. Under pH 5.4 conditions, these nanogels released 78% of the originally loaded CPT over a period of 70 h. The antiproliferative potential of PAH-Ag-CPT nanogels (at [CPT]=0.6 μg/mL) against MCF-7 breast adeno-carcinoma cells were ∼350% higher compared to that of the free CPT as evidenced by high cellular internalization of these nanogels. Induction of apoptosis in MCF-7 breast adeno-carcinoma cells by PAH-Ag-CPT nanogels was evidenced by accumulation of late apoptotic cell population. Drug along with the PAH-Ag NPs were also encapsulated in a pH responsive hydrogel through in situ gelation at room temperature using acrylic acid as the cross-linker. The resulting hydrogel released quantitative amounts of both drug and PAH-Ag NPs over a period of 16 h. The simplicity of synthesis and ease of drug loading with efficient release render these NPs a viable candidate for various biomedical applications, and moreover this synthetic procedure may be extended to other metal NPs.
