[PMID: 38014928 DOI: 10.1002/mas.21869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 10/10/2023] [Accepted: 11/08/2023] [Indexed: 11/29/2023]
Abstract
Biodegradable polymers have been getting more and more attention because of their contribution to the plastic pollution environmental issues and to move towards a circular economy. Nevertheless, biodegradable materials still exhibit various disadvantages restraining a widespread use in the market. Therefore, additional research efforts are required to improve their performance. Mass spectrometry (MS) affords a relevant contribution to optimize biodegradable polymer synthesis, to confirm macromolecular structures, to examine along the time the progress of degradation processes and highlight advantages and drawbacks in the extensive applications. This review aims to provide an overview of the MS investigations carried out to support the synthesis of biodegradable polymers, with helpful information on undesirable products or polymerization mechanism, to understand deterioration pathways by the structure of degradation products and to follow drug release and pharmacokinetic. Additionally, it summarizes MS studies addressed on environmental and health issues related to the extensive use of plastic materials, that is, potential migration of additives or microplastics identification and quantification. The paper is focused on the most significant studies relating to synthetic and microbial biodegradable polymers published in the last 15 years, not including agro-polymers such as proteins and polysaccharides.

Poly-l-glutamic acid modification modulates the bio-nano interface of a therapeutic anti-IGF-1R antibody in prostate cancer. Biomaterials 2023; 301:122280. [PMID: 37598440 DOI: 10.1016/j.biomaterials.2023.122280] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 08/04/2023] [Accepted: 08/12/2023] [Indexed: 08/22/2023]
Abstract
Modifying biological agents with polymers such as polyethylene glycol (PEG) has demonstrated clinical benefits; however, post-market surveillance of PEGylated derivatives has revealed PEG-associated toxicity issues, prompting the search for alternatives. We explore how conjugating a poly-l-glutamic acid (PGA) to an anti-insulin growth factor 1 receptor antibody (AVE1642) modulates the bio-nano interface and anti-tumor activity in preclinical prostate cancer models. Native and PGA-modified AVE1642 display similar anti-tumor activity in vitro; however, AVE1642 prompts IGF-1R internalization while PGA conjugation prompts higher affinity IGF-1R binding, thereby inhibiting IGF-1R internalization and altering cell trafficking. AVE1642 attenuates phosphoinositide 3-kinase signaling, while PGA-AVE1642 inhibits phosphoinositide 3-kinase and mitogen-activated protein kinase signaling. PGA conjugation also enhances AVE1642's anti-tumor activity in an orthotopic prostate cancer mouse model, while PGA-AVE1642 induces more significant suppression of cancer cell proliferation/angiogenesis than AVE1642. These findings demonstrate that PGA conjugation modulates an antibody's bio-nano interface, mechanism of action, and therapeutic activity.

Abstract
Lysosomes play a central role in cellular homeostasis and alterations in this compartment associate with many diseases. The most studied example is that of lysosomal storage disorders (LSDs), a group of 60 + maladies due to genetic mutations affecting lysosomal components, mostly enzymes. This leads to aberrant intracellular storage of macromolecules, altering normal cell function and causing multiorgan syndromes, often fatal within the first years of life. Several treatment modalities are available for a dozen LSDs, mostly consisting of enzyme replacement therapy (ERT) strategies. Yet, poor biodistribution to main targets such as the central nervous system, musculoskeletal tissue, and others, as well as generation of blocking antibodies and adverse effects hinder effective LSD treatment. Drug delivery systems are being studied to surmount these obstacles, including polymeric constructs and nanoparticles that constitute the focus of this article. We provide an overview of the formulations being tested, the diseases they aim to treat, and the results observed from respective in vitro and in vivo studies. We also discuss the advantages and disadvantages of these strategies, the remaining gaps of knowledge regarding their performance, and important items to consider for their clinical translation. Overall, polymeric nanoconstructs hold considerable promise to advance treatment for LSDs.

Abstract
Adagen, an enzyme replacement treatment for adenosine deaminase deficiency, was the first protein-polymer conjugate to be approved in early 1990s. Post this regulatory approval, numerous polymeric drugs and polymeric nanoparticles have entered the market as advanced or next-generation polymer-based therapeutics, while many others have currently been tested clinically. The polymer conjugation to therapeutic moiety offers several advantages, like enhanced solubilization of drug, controlled release, reduced immunogenicity, and prolonged circulation. The present review intends to highlight considerations in the design of therapeutically effective polymer-drug conjugates (PDCs), including the choice of linker chemistry. The potential synthetic strategies to formulate PDCs have been discussed along with recent advancements in the different types of PDCs, i.e., polymer-small molecular weight drug conjugates, polymer-protein conjugates, and stimuli-responsive PDCs, which are under clinical/preclinical investigation. Current impediments and regulatory hurdles hindering the clinical translation of PDC into effective therapeutic regimens for the amelioration of disease conditions have been addressed.

Abstract
Polysaccharides are abundant natural polymers, which in nature are at times covalently modified with peptides and proteins. Polysaccharide-protein or polysaccharide-peptide conjugates, natural or otherwise, may have increased solubility, improved emulsion properties, prolonged circulation time, reduced immunogenicity, and enhanced selectivity for targeting specific tissues compared to native peptides and proteins. In this paper, we will review recent advances in synthetic methods for producing polysaccharide-protein conjugates and discuss their advantages with a focus on drug targeting.

Abstract
The formation in aqueous media of molecular nanoparticles from a bolaamphiphile (SucIleCsa) incorporating a disulfide moiety is described. The particles can be loaded efficiently with the lipophilic mitochondrial marker DiOC6(3), quenching its fluorescence, which is recovered upon reductive particle disassembly. DiOC6(3) transport into human colorectal adenocarcinoma cells (HT-29) is demonstrated using flow cytometry and confocal scanning fluorescence microscopy. A significant increase in intracellular fluorescence is observed when the cells are stimulated to produce glutathione (GSH). These new molecular nanoparticles can be considered a theranostic tool that simultaneously achieves targeted delivery of lipophilic substances and signals high levels of GSH.

Abstract
PEGylation is the standard approach for prolonging the plasma exposure of protein therapeutics but has limitations. We explored whether polymers prepared by Reversible Addition-Fragmentation chain-Transfer (RAFT) may provide better alternatives to polyethylene glycol (PEG). Four RAFT polymers were synthesised with varying compositions, molar mass (Mn), and structures, including a homopolymer of N-(2-hydroxypropyl)methacrylamide, (pHPMA) and statistical copolymers of HPMA with poly(ethylene glycol methyl ether acrylate) p(HPMA-co-PEGA); HPMA and N-acryloylmorpholine, p(HPMA-co-NAM); and HPMA and N-isopropylacrylamide, p(HPMA-co-NIPAM). The intravenous pharmacokinetics of the polymers were then evaluated in rats. The in vitro activity and in vivo pharmacokinetics of p(HPMA-co-NIPAM)-conjugated trastuzumab Fab' and full length mAb were then evaluated. p(HPMA-co-NIPAM) prolonged plasma exposure more avidly compared to the other p(HPMA) polymers or PEG, irrespective of molecular weight. When conjugated to trastuzumab-Fab', p(HPMA-co-NIPAM) prolonged plasma exposure of the Fab' similar to PEG-Fab'. The generation of anti-PEG IgM in rats 7 days after intravenous and subcutaneous dosing of p(HPMA-co-NIPAM) conjugated trastuzumab mAb was also examined and was shown to exhibit lower immunogenicity than the PEGylated construct. These data suggest that p(HPMA-co-NIPAM) has potential as a promising copolymer for use as an alternative conjugation strategy to PEG, to prolong the plasma exposure of therapeutic proteins.

Abstract
Biological drugs or biopharmaceuticals off patent open a large market for biosimilars and biobetters, follow-on biologics. Biobetters, in particular, are new drugs designed from existing ones with improved properties such as higher selectivity, stability, half-life and/or lower toxicity/immunogenicity. Glycosylation is one of the most used strategies to improve biological drugs, nonetheless bioconjugation is an additional alternative and refers to the covalent attachment of polymers to biological drugs. Extensive research on novel polymers is underway, nonetheless PEGylation is still the best alternative with the longest clinical track record. Innovative trends based on genetic engineering techniques such as fusion proteins and PASylation are also promising. In this review, all these alternatives wereexplored as well as current market trends, legislation and future perspectives.

Abstract
Exposed collagen surface on diseased blood vessel wall is a trigger of platelet adhesion and subsequent thrombus formation, which is associated with many serious diseases such as myocardial infarction and stroke. Various antithrombotic agents have been developed, but are usually targeted on blood components such as platelet, which suffered from the risk of bleeding due to interference with hemostasis. In contrast, blocking the exposed collagen surface would prevent thrombus formation without the risk of bleeding. In the present study, an antithrombotic nanoconjugate (LWWNSYY-poly glutamic acid, L7-PGA) targeting collagen surface was designed by immobilizing heptapeptide LWWNSYY, a biomimetic inhibitor designed in our previous work, on poly(l-glutamic acid). Successful binding of L7-PGA on the collagen surface was confirmed by a negative ΔG of -5.99 ± 0.26 kcal/mol. L7-PGA was found to effectively inhibit platelet adhesion on the collagen surface, with a reduced IC50 of only 1/5 of that of free LWWNSYY. The inhibition of thrombus formation by L7-PGA was also validated in vivo by a reduction of 31.2% in the weight of thrombus. These results highlight L7-PGA as an effective inhibitor of arterial thrombus formation via blocking exposed collagen surface, which would be helpful for the development of novel antithrombotic nanomedicine.

Abstract
Photodynamic therapy (PDT) has shown its promise in the treatment of cancer. Herein, a dendron-functionalized polyglutamic acid (PGA) polymer (PG-L8G-Ppa-Dendron, PGPD) is synthesized and it is conjugated with pyropheophorbide-a (Ppa) for the first time to treat triple negative breast cancer (TNBC), whereas a linear polyglutamate-Ppa conjugate (PGP) is synthesized as a control. Compared to the linear counterpart, the glycosylated polymer-based PGPD with a dendritic structure has excellent solubility and it self-assembles to form uniform-sized nanoparticles. PGPD displays a highly effective PDT effect in the animal model, evidenced with effective induction of reactive oxygen species (ROS) production and cell apoptosis. This may be due to an enhanced efficiency in delivery and accumulation of Ppa by this glycosylated dendritic polymer at tumor sites. Therefore, PGPD can be a highly effective and biosafe nanoagent for PDT of TNBC.

Abstract
Postoperative peritoneal adhesions were frequent complications for almost any types of abdominal and pelvic surgery. This led to numerous medical problems and huge financial burden to the patients. Current anti-adhesion strategies focused mostly on physical barriers including films and hydrogels. However, they can only alleviate or reduce adhesions to certain level and their applying processes were far from ideal. This work reported the development of a biodegradable zwitterionic cream gel presenting a series of characters for an idea anti-adhesion material, including unique injectable yet malleable and self-supporting properties, which enabled an instant topical application, no curing, waiting or suturing, no hemostasis requirement, protein/cell resistance and biodegradability. The cream gel showed a major advancement in anti-adhesion efficacy by completely and reliably preventing a primary and a more severe recurrent adhesion in rat models.

Abstract
Peptide-based subunit vaccines are attractive in view of personalized cancer vaccination with neo-antigens, as well as for the design of the newest generation of vaccines against infectious diseases. Key to mounting robust antigen-specific immunity is delivery of antigen to antigen-presenting (innate immune) cells in lymphoid tissue with concomitant innate immune activation to promote antigen presentation to T cells and to shape the amplitude and nature of the immune response. Nanoparticles that co-deliver both peptide antigen and molecular adjuvants are well suited for this task. However, in the context of peptide-based antigen, an unmet need exists for a generic strategy that allows for co-encapsulation of peptide and molecular adjuvants due to the stark variation in physicochemical properties based on the amino acid sequence of the peptide. These properties also strongly differ from those of many molecular adjuvants. Here, we devise a lipid nanoparticle (LNP) platform that addresses these issues. Key in our concept is poly(l-glutamic acid) (PGA), which serves as a hydrophilic backbone for conjugation of, respectively, peptide antigen (Ag) and an imidazoquinoline (IMDQ) TLR7/8 agonist as a molecular adjuvant. Making use of the PGA's polyanionic nature, we condensate PGA-Ag and PGA-IMDQ into LNP by electrostatic interaction with an ionizable lipid. We show in vitro and in vivo in mouse models that LNP encapsulation favors uptake by innate immune cells in lymphoid tissue and promotes the induction of Ag-specific T cells responses both after subcutaneous and intravenous administration.

Abstract
![]()
Polymer
masked–unmasked protein therapy (PUMPT) uses conjugation
of a biodegradable polymer, such as dextrin, hyaluronic acid, or poly(l-glutamic acid), to mask a protein or peptide’s activity;
subsequent locally triggered degradation of the polymer at the target
site regenerates bioactivity in a controllable fashion. Although the
concept of PUMPT is well established, the relationship between protein
unmasking and reinstatement of bioactivity is unclear. Here, we used
dextrin–colistin conjugates to study the relationship between
the molecular structure (degree of unmasking) and biological activity.
Size exclusion chromatography was employed to collect fractions of
differentially degraded conjugates and ultraperformance liquid chromatography–mass
spectrometry (UPLC–MS) employed to characterize the corresponding
structures. Antimicrobial activity was studied using a minimum inhibitory
concentration (MIC) assay and confocal laser scanning microscopy of
LIVE/DEAD-stained biofilms with COMSTAT analysis. In vitro toxicity
of the degraded conjugate was assessed using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl
tetrazolium bromide assay. UPLC–MS revealed that the fully
“unmasked” dextrin–colistin conjugate composed
of colistin bound to at least one linker, whereas larger species were
composed of colistin with varying lengths of glucose units attached.
Increasing the degree of dextrin modification by succinoylation typically
led to a greater number of linkers bound to colistin. Greater antimicrobial
and antibiofilm activity were observed for the fully “unmasked”
conjugate compared to the partially degraded species (MIC = 0.25 and
2–8 μg/mL, respectively), whereas dextrin conjugation
reduced colistin’s in vitro toxicity toward kidney cells, even
after complete unmasking. This study highlights the importance of
defining the structure–antimicrobial activity relationship
for novel antibiotic derivatives and demonstrates the suitability
of LC–MS to aid the design of biodegradable polymer–antibiotic
conjugates.

Abstract
Polymer conjugation is a clinically proven approach to generate long acting protein drugs with decreased immune responses. Although poly(ethylene glycol) (PEG) is one of the most commonly used conjugation partners due to its unstructured conformation, its therapeutic application is limited by its poor biodegradability, propensity to induce an anti-PEG immune response, and the resultant accelerated blood clearance (ABC) effect. Moreover, the prevailing preference of unstructured polymers for protein conjugation still lacks strong animal data support with appropriate control reagents. By using two biodegradable synthetic polypeptides with similar structural compositions (l-P(EG3Glu) and dl-P(EG3Glu)) for site-specific protein modification, in the current study, we systematically investigate the effect of the polymer conformation on the in vivo pharmacological performances of the resulting conjugates. Our results reveal that the conjugate l20K-IFN, interferon (IFN) modified with the helical polypeptide l-P(EG3Glu) shows improved binding affinity, in vitro antiproliferative activity, and in vivo efficacy compared to those modified with the unstructured polypeptide analogue dl-P(EG3Glu) or PEG. Moreover, l20K-IFN triggered significantly less antidrug and antipolymer antibodies than the other two. Importantly, the unusual findings observed in the IFN series are reproduced in a human growth hormone (GH) conjugate series. Subcutaneously infused l20K-GH, GH modified with l-P(EG3Glu), evokes considerably less anti-GH and antipolymer antibodies compared to those modified with dl-P(EG3Glu) or PEG (dl20K-GH or PEG20K-GH). As a result, repeated injections of dl20K-GH or PEG20K-GH, but not l20K-GH, result in a clear ABC effect and significantly diminished drug availability in the blood. Meanwhile, immature mouse bone marrow cells incubated with the helical l20K-GH exhibit decreased drug uptake and secretion of proinflammatory cytokines compared to those treated with one of the other two GH conjugates bearing unstructured polymers. Taken together, the current study highlights an urgent necessity to systematically reassess the pros and cons of choosing unstructured polymers for protein conjugation. Furthermore, our results also lay the foundation for the development of next-generation biohybrid drugs based on helical synthetic polypeptides.

Abstract
Polymer therapeutics (PTs) provides a potentially exciting approach for the treatment of many diseases by enhancing aqueous solubility and altering drug pharmacokinetics at both the whole organism and subcellular level leading to improved therapeutic outcomes. However, the failure of many polymer-drug conjugates in clinical trials suggests that we may need to stratify patients in order to match each patient to the right PT. In this concise review, we hope to assess potential PT-specific biomarkers for cancer treatment, with a focus on new studies, detection methods, new models and the opportunities this knowledge will bring for the development of novel PT-based anti-cancer strategies. We discuss the various "hurdles" that a given PT faces on its passage from the syringe to the tumor (and beyond), including the passage through the bloodstream, tumor targeting, tumor uptake and the intracellular release of the active agent. However, we also discuss other relevant concepts and new considerations in the field, which we hope will provide new insight into the possible applications of PT-related biomarkers.

Abstract
Cyclization and polymer conjugation are two commonly used approaches for enhancing the pharmacological properties of protein drugs. However, cyclization of parental proteins often only affords a modest improvement in biochemical or cell-based in vitro assays. Moreover, very few studies have included a systematic pharmacological evaluation of cyclized protein-based therapeutics in live animals. On the other hand, polymer-conjugated proteins have longer circulation half-lives but usually show poor tumor penetration and suboptimal pharmacodynamics due to increased steric hindrance. We herein report the generation of a head-to-tail interferon-poly(α-amino acid) macrocycle conjugate circ-P(EG3Glu)20-IFN by combining the aforementioned two approaches. We then compared the antitumor pharmacological activity of this macrocycle conjugate against its linear counterparts, N-P(EG3Glu)20-IFN, C-IFN-P(EG3Glu)20, and C-IFN-PEG. Our results found circ-P(EG3Glu)20-IFN to show considerably greater stability, binding affinity, and in vitro antiproliferative activity toward OVCAR3 cells than the three linear conjugates. More importantly, circ-P(EG3Glu)20-IFN exhibited longer circulation half-life, remarkably higher tumor retention, and deeper tumor penetration in vivo. As a result, administration of the macrocyclic conjugate could effectively inhibit tumor progression and extend survival in mice bearing established xenograft human OVCAR3 or SKOV3 tumors without causing severe paraneoplastic syndromes. Taken together, our study provided until now the most relevant experimental evidence in strong support of the in vivo benefit of macrocyclization of protein-polymer conjugates and for its application in next-generation therapeutics.

Polymer-directed enzyme prodrug therapy (PDEPT) and polymer enzyme liposome therapy (PELT) are two-step therapies developed to provide anticancer drugs site-selective intratumoral accumulation and release. Nanomedicines, such as polymer-drug conjugates and liposomal drugs, accumulate in the tumor site due to extravasation-dependent mechanism (enhanced permeability and retention - EPR - effect), and further need to cross the cellular membrane and release their payload in the intracellular compartment. The subsequent administration of a polymer-enzyme conjugate able to accumulate in the tumor tissue and to trigger the extracellular release of the active drug showed promising preclinical results. The development of polymer-enzyme, polymer-drug conjugates and liposomal drugs had undergone a vast advancement over the past decades. Several examples of enzyme mimics for in vivo therapy can be found in the literature. Moreover, polymer therapeutics often present an enzyme-sensitive mechanism of drug release. These nanomedicines can thus be optimal substrates for PDEPT and this review aims to provide new insights and stimuli toward the future perspectives of this promising combination.

Abstract
Colon cancer is one of the most common death-related cancers in the world. For treating colon cancer, it is crucial to detect and remove malignant lesions early. Here, we developed hyaluronate (HA)-peanut agglutinin (PNA) conjugates for the bioimaging of colon cancer. The HA-PNA conjugates were successfully synthesized by the coupling reaction between aldehyde-modified HA and the N-terminal amine group of PNA. For diagnostic imaging, rhodamine B (RhoB) was chemically conjugated onto PNA in HA-PNA conjugates. After intraluminal injection of HA-PNA-RhoB conjugates into tumor-bearing mice, small-sized colon cancers could be effectively visualized by ex vivo imaging with an in vivo imaging system (IVIS) and a two-photon microscope. With these results taken together, we could confirm the feasibility of HA-PNA-RhoB conjugates as a bioimaging agent for detecting colon cancers.

Abstract
Alanine:glyoxylate aminotransferase (AGT) is a liver peroxisomal enzyme whose deficit causes the rare disorder Primary Hyperoxaluria Type I (PH1). We now describe the conjugation of poly(ethylene glycol)-co-poly(L-glutamic acid) (PEG-PGA) block-co-polymer to AGT via the formation of disulfide bonds between the polymer and solvent-exposed cysteine residues of the enzyme. PEG-PGA conjugation did not affect AGT structural/functional properties and allowed the enzyme to be internalized in a cellular model of PH1 and to restore glyoxylate-detoxification. The insertion of the C387S/K390S amino acid substitutions, known to favor interaction with the peroxisomal import machinery, reduced conjugation efficiency, but endowed conjugates with the ability to reach the peroxisomal compartment. These results, along with the finding that conjugates are hemocompatible, stable in plasma, and non-immunogenic, hold promise for the development of polypeptide-based AGT conjugates as a therapeutic option for PH1 patients and represent the base for applications to other diseases related to deficits in peroxisomal proteins.

Abstract
Mesoporous silica nanoparticles (MSNs) are highly attractive as supports in the design of controlled delivery systems that can act as containers for the encapsulation of therapeutic agents, overcoming common issues such as poor water solubility and poor stability of some drugs and also enhancing their bioavailability. In this context, we describe herein the development of polyglutamic acid (PGA)-capped MSNs that can selectively deliver rhodamine B and doxorubicin. PGA-capped MSNs remain closed in an aqueous environment, yet they are able to deliver the cargo in the presence of pronase because of the hydrolysis of the peptide bonds in PGA. The prepared solids released less than 20% of the cargo in 1 day in water, whereas they were able to reach 90% of the maximum release of the entrapped guest in ca. 5 h in the presence of pronase. Studies of the PGA-capped nanoparticles with SK-BR-3 breast cancer cells were also undertaken. Rhodamine-loaded nanoparticles were not toxic, whereas doxorubicin-loaded nanoparticles were able to efficiently kill more than 90% of the cancer cells at a concentration of 100 μg/mL.

Abstract
A strategy to construct different stimuli responsive polymers from post polymerization modifications of a single polymer scaffold via thiol-disulfide exchange has been developed. Here, we report on a random copolymer that enables the design and syntheses of a series of dual or multi-stimuli responsive nanoassemblies using a simple post-polymerization modification step. The reactive functional group involves a side chain monopyridyl disulfide unit, which rapidly and quantitatively reacts with various thiols under mild conditions. Independent and concurrent incorporation of physical, chemical or biologically responsive properties have been demonstrated. We envision that this strategy may open up opportunities to simplify the synthesis of multi-functional polymers with broad implications in a variety of biological applications.

Abstract
Poly(ethylene glycol) (PEG)-protein therapeutics exhibit enhanced pharmacokinetics, but have drawbacks including decreased protein activities and polymer accumulation in the body. Therefore a major aim for second-generation polymer therapeutics is to introduce degradability into the backbone. Herein we describe the synthesis of poly(poly(ethylene glycol methyl ether methacrylate)) (pPEGMA) degradable polymers with protein-reactive end-groups via reversible addition-fragmentation chain transfer (RAFT) polymerization, and the subsequent covalent attachment to lysozyme through a reducible disulfide linkage. RAFT copolymerization of cyclic ketene acetal (CKA) monomer 5,6-benzo-2-methylene-1,3-dioxepane (BMDO) with PEGMA yielded two polymers with number-average molecular weight (Mn ) (GPC) of 10.9 and 20.9 kDa and molecular weight dispersities (Ð) of 1.34 and 1.71, respectively. Hydrolytic degradation of the polymers was analyzed by 1H-NMR and GPC under basic and acidic conditions. The reversible covalent attachment of these polymers to lysozyme, as well as the hydrolytic and reductive cleavage of the polymer from the protein, was analyzed by gel electrophoresis and mass spectrometry. Following reductive cleavage of the polymer, an increase in activity was observed for both conjugates, with the released protein having full activity. This represents a method to prepare PEGylated proteins, where the polymer is readily cleaved from the protein and the main chain of the polymer is degradable.
