Abstract
Secondary structure formation differentiates polypeptides from most of the other synthetic polymers, and the transitions from random coils to rod-like α-helices or β-sheets represent an additional parameter to direct self-assembly and the morphology of nanostructures. We investigated the influence of distinct secondary structures on the self-assembly of reactive amphiphilic polypept(o)ides. The individual morphologies can be preserved by core cross-linking via chemoselective disulfide bond formation. A series of thiol-responsive copolymers of racemic polysarcosine-block-poly(S-ethylsulfonyl-dl-cysteine) (pSar-b-p(dl)Cys), enantiopure polysarcosine-block-poly(S-ethylsulfonyl-l-cysteine) (pSar-b-p(l)Cys), and polysarcosine-block-poly(S-ethylsulfonyl-l-homocysteine) (pSar-b-p(l)Hcy) was prepared by N-carboxyanhydride polymerization. The secondary structure of the peptide segment varies from α-helices (pSar-b-p(l)Hcy) to antiparallel β-sheets (pSar-b-p(l)Cys) and disrupted β-sheets (pSar-b-p(dl)Cys). When subjected to nanoprecipitation, copolymers with antiparallel β-sheets display the strongest tendency to self-assemble, whereas disrupted β-sheets hardly induce aggregation. This translates to worm-like micelles, solely spherical micelles, or ellipsoidal structures, as analyzed by atomic force microscopy and cryogenic transmission electron microscopy, which underlines the potential of secondary structure-driven self-assembly of synthetic polypeptides.

Abstract
Antimicrobial polypeptides are promising mimics of antimicrobial peptides (AMPs) with low risks of antimicrobial resistance (AMR). Polypeptides with facile and efficient production, high antimicrobial activity, and low toxicity toward mammalian cells are highly desirable for practical applications. Herein, triblock copolypeptides with chloro groups (PPGn-PCPBLGm) and different main-chain lengths were synthesized via an ultrafast ring-opening polymerization (ROP) using a macroinitiator, namely poly(propylene glycol) bis(2-aminopropyl ether), and purified or nonpurified monomer (i.e., CPBLG-NCA). PPGn-PCPBLGm with 90 amino acid residues can be readily prepared within 300 s. Imidazolium-based block copolypeptides (PPGn-PILm) were facilely prepared via nucleophilic substitution of PPGn-PCPBLGm with NaN3 and subsequent "click" chemistry. α-Helical PPGn-PILm can self-assemble into nanostructured and cationic micelles which displayed highly potent antimicrobial activity and low hemolysis. The top-performing material, namely PPG34-PIL70, showed low minimum inhibitory concentration (MIC) against both Gram-positive S. aureus and Gram-negative E. coli (25 μg mL-1). It also displayed low toxicity against mouse embryonic fibroblast (NIH 3T3) and human embryonic kidney (293T) cells at 2× MIC.

Abstract
In only a few decades, lithium-ion batteries have revolutionized technologies, enabling the proliferation of portable devices and electric vehicles1, with substantial benefits for society. However, the rapid growth in technology has highlighted the ethical and environmental challenges of mining lithium, cobalt and other mineral ore resources, and the issues associated with the safe usage and non-hazardous disposal of batteries2. Only a small fraction of lithium-ion batteries are recycled, further exacerbating global material supply of strategic elements3-5. A potential alternative is to use organic-based redox-active materials6-8 to develop rechargeable batteries that originate from ethically sourced, sustainable materials and enable on-demand deconstruction and reconstruction. Making such batteries is challenging because the active materials must be stable during operation but degradable at end of life. Further, the degradation products should be either environmentally benign or recyclable for reconstruction into a new battery. Here we demonstrate a metal-free, polypeptide-based battery, in which viologens and nitroxide radicals are incorporated as redox-active groups along polypeptide backbones to function as anode and cathode materials, respectively. These redox-active polypeptides perform as active materials that are stable during battery operation and subsequently degrade on demand in acidic conditions to generate amino acids, other building blocks and degradation products. Such a polypeptide-based battery is a first step to addressing the need for alternative chemistries for green and sustainable batteries in a future circular economy.

Abstract
Antimicrobial peptides (AMPs) have been considered as a promising new tool to combat the antimicrobial resistance (AMR) crisis. However, the high toxicity and high cost of AMPs hampered their further development. Herein, a series of star poly(L-lysine) (PLL) homo- and copolymers with excellent antimicrobial activity and improved biocompatibility were prepared by the combination of ultra-fast ring opening polymerization (ROP) and side-chain modification. The amine-terminated polyamidoamine dendrimer (Gx-PAMAM) mediated ROP of Nε-tert-butyloxycarbonyl-L-lysine N-carboxyanhydride (Boc-L-Lys-NCA) and γ-benzyl-L-glutamic acid-based N-carboxyanhydride (PBLG-NCA) was able to prepare star PLL homo- and copolymers with 400 residues within 50 min. While the star PLL homopolymers exhibited low minimum inhibitory concentration (MIC = 50-200 μg mL-1) against both Gram-positive and Gram-negative bacteria (i.e., S. aureus and E. coli), they showed high toxicity against various mammalian cell lines. The star PLL copolymers with low contents of hydrophobic and hydroxyl groups showed enhanced antimicrobial activity (MIC = 25-50 μg mL-1) and improved mammalian cell viability. Both SEM and CLSM results indicated the antimicrobial mechanism of membrane disruption.

Abstract
In recent years, gene therapy has come into the spotlight for the prevention and treatment of a wide range of diseases. Polypeptides have been widely used in mediating nucleic acid delivery, due to their versatilities in chemical structures, desired biodegradability, and low cytotoxicity. Chemistry plays an essential role in the development of innovative polypeptides to address the challenges of producing efficient and safe gene vectors. In this Review, we mainly focused on the latest chemical advances in the design and preparation of polypeptide-based nucleic acid delivery vehicles. We first discussed the synthetic approach of polypeptides via ring-opening polymerization (ROP) of N-carboxyanhydrides (NCAs), and introduced the various types of polypeptide-based gene delivery systems. The extracellular and intracellular barriers against nucleic acid delivery were then outlined, followed by detailed review on the recent advances in polypeptide-based delivery systems that can overcome these barriers to enable in vitro and in vivo gene transfection. Finally, we concluded this review with perspectives in this field.

Abstract
Water-soluble polypeptides are a class of synthetic polymers with peptide bond frameworks imitating natural proteins and have broad prospects in biological applications. The regulation and dynamic transition of the secondary structures of water-soluble polypeptides have a great impact on their physio-chemical properties and biological functions. In this review article, we briefly introduce the current strategies to synthesize polypeptides and modulate their secondary structures. We then discuss the factors affecting the conformational stability/transition of polypeptides and the potential impact of side-chain functionalization on the ordered secondary structures, such as α-helix and β-sheet. We then summarize the biological applications of water-soluble polypeptides such as cell penetration, gene delivery, and antimicrobial treatment, highlighting the important roles of ordered secondary structures therein.

Abstract
To synthesize well-defined poly (α-amino acid)s (PAAs), ring opening polymerizations (ROP) of cyclic monomers of α-amino acid N-carboxyanhydrides (NCAs) and N-thiocarboxyanhydrides (NTAs) are most widely used. In this mini-review, we summarize the mechanism details of the monomer preparation and ROP. The present study used density functional theory calculations to reveal the mechanisms together with experimental phenomena in the past decades. Detailed discussion includes normal amine mechanism and the selectivity of the initiators bearing various nucleophilic groups.

Abstract
Aliphatic polythioesters are popular polymers because of their appealing performance such as metal coordination ability, high refractive indices, and biodegradability. One of the most powerful approaches for generating these polymers is the ring-opening polymerization (ROP) of cyclic monomers. However, the synthesis of precisely controlled polythioesters via ROP of thiolactones still faces formidable challenges, including the minimal functional diversity of available thiolactone monomers, as well as inevitable transthioesterification side reactions. Here we introduce a hyperactive class of S-carboxyanhydride (SCA) monomers derived from amino acids that are significantly more reactive than thiolactones for ultrafast and selective ROP. Inclusion of the initiator PPNOBz ([PPN]=bis(triphenylphosphine)-iminium) with chain transfer agent benzoic acid, the polymerizations that can be operated in open vessels reach complete conversion within minutes (1-2 min) at room temperature, yielding polythioesters with predictable molecular weight, low dispersities, retained stereoregularity and chemical recyclability. Most fascinating are the functionalized SCAs that allow the incorporating of functional groups along the polythioester chain and thus finely tune their physicochemical performance. Computational studies were carried out to explore the origins of the distinctive rapidity and exquisite selectivity of the polymerizations, offering mechanistic insight and explaining why high polymerizability of SCA monomer is able to facilitate exquisitely selective ring-opening for enchainment over competing transthioesterification and backbiting reactions.

Abstract
Hydrogels are perfectly suited to support cell and tissue growth in advanced tissue engineering applications as well as classical wound treatment scenarios. Ideal hydrogel materials for these applications should be easy to produce, biocompatible, resorbable and antimicrobial. Here we report the fabrication of degradable covalent antimicrobial lysine and tryptophan containing copolypeptide hydrogels, whereby the hydrogel properties can be independently modulated by the copolypeptide monomer ratio and chiral composition. Well-defined statistical copolypeptides comprising different overall molecular weights as well as ratios of l- and d-lysine and tryptophan at ratios of 35 : 15, 70 : 30 and 80 : 20 were obtained by N-carboxyanhydride (NCA) polymerisation and subsequently crosslinked by the selective reaction of bifunctional triazolinedione (TAD) with tryptophan. Real-time rheology was used to monitor the crosslinking reaction recording the fastest increase and overall modulus for copolypeptides with the higher tryptophan ratio. Water uptake of cylindrical hydrogel samples was dependent on crosslinking ratio but found independent of chiral composition, while enzymatic degradation proceeded significantly faster for samples containing more l-amino acids. Antimicrobial activity on a range of hydrogels containing different polypeptide chain lengths, lysine/tryptophan composition and l/d enantiomers was tested against reference laboratory strains of Gram-negative Escherichia coli (E. coli; ATCC25922) and Gram-positive, Staphylococcus aureus (S. aureus; ATCC25923). log reductions of 2.8-3.4 were recorded for the most potent hydrogels. In vitro leachable cytotoxicity tests confirmed non-cytotoxicity as per ISO guidelines.

Abstract
Poly(β-peptoid)s (N-substituted poly-β-alanines) are an intriguing class of pseudopeptidic materials for biomedical applications, but the polymers prepared by solution polymerization have restricted diversity and functionality due to synthetic difficulty. Synthesis of structurally diverse poly(β-peptoid)s is highly desirable yet challenging. Herein, we report a new approach to synthesize skeletal chiral β-peptoid polymers from readily available aspartic acid derivatives. Two types of N-substituted β3-homoalanine monomers, i.e., N-(methyl propionate)-Asp-OMe ( N MeP-Asp-OMe) and N-(tert-butyl propionate)-Asp-OMe ( N tBuP-Asp-OMe), were synthesized in high yield via an aza-Michael addition reaction between l-aspartic acid-1-methyl ester (l-Asp-OMe) and acrylate species. Both N-substituted β3-homoalanines can be readily converted into polymerizable N-substituted β3-homoalanine N-carboxyanhydrides (β-NNCAs). Subsequent ring-opening polymerization (ROP) of these β-NNCA monomers provides access to oligo(β-peptoid)s and mPEG-poly(β-peptoid) diblocks with backbone chirality. Their conformations were preliminarily studied by circular dichroism (CD) spectra and Fourier transform infrared spectroscopy (FT-IR). The synthetic strategy would significantly facilitate the development of novel poly(β-peptoid)s with well-defined and diverse structures.

Abstract
Mucins are bottlebrush biopolymers that are glycoproteins on the surfaces of cells and as hydrogels secreted inside and outside the body. Mucin function in biology includes cell-cell recognition, signaling, protection, adhesion, and lubrication. Because of their attractive and diverse properties, mucins have recently become the focus of synthetic efforts by researchers who hope to understand and emulate these biomaterials. This review is focused on the development of methodologies for preparing mucin-inspired synthetic oligomers and glycopolymers, including solid-phase synthesis, polymerization of glycosylated monomers, and post-polymerization grafting of glycans to polymer chains. How these synthetic mucins have been used in health applications is discussed. Natural mucins are formed from a conserved set of monomers that are combined into chains of different sequences and lengths to achieve materials with widely diverse properties. Adopting this design paradigm from natural mucins could lead to next-generation bioinspired synthetic materials.

Abstract
Enzyme-responsive polypeptide vesicles have attracted considerable attention for precision theranostics because of their biocompatibility, biodegradability, and unique secondary conformation transition triggered by the catalytic actions of enzymes. These promising potentials of polypeptide vesicles could be limited in a drug delivery system by the very slow enzyme diffusion rate into vesicles that could reduce the efficacy of the drug. On the other hand, stimuli-responsive polymeric vesicles that respond to stimuli can undergo microstructure destruction for the burst release of drugs, which would penetrate through the membrane of dead cells and the tumor extracellular matrix, inducing acute toxicity to neighboring cells. Here, we designed amphiphilic PEG-polypeptide copolymers containing esterase-labile carbamate-caged primary amines. It was found that the diblock can self-assemble into vesicular structures. Esterase-triggered self-immolative decaging reactions could quickly release the primary amine moiety of monomers that can undergo an amidation reaction for transition of the bilayer of vesicles from hydrophobic to partially hydrophilic. This esterase-responsive process retains the nanostructure of vesicles but permeabilizes the vesicle membrane, which can afford the sustained release of encapsulating drugs. These esterase-responsive polypeptide vesicles mediate selective cytotoxicity in cancer cells with high esterase expression over normal fibroblasts with low esterase, enabling the potent anticancer chemotherapy with minimized side effects.

Abstract
Stimuli-responsive polymers have been widely studied in many applications such as biomedicine, nanotechnology, and catalysis. Temperature is one of the most commonly used external triggers, which can be highly controlled with excellent reversibility. Thermoresponsive polymers exhibiting a reversible phase transition in a controlled manner to temperature are a promising class of smart polymers that have been widely studied. The phase transition behavior can be tuned by polymer architectures, chain-end, and various functional groups. Particularly, thermoresponsive polypeptoid is a type of promising material that has drawn growing interest because of its excellent biocompatibility, biodegradability, and bioactivity. This paper summarizes the recent advances of thermoresponsive polypeptoids, including the synthetic methods and functional groups as well as their applications.

Abstract
Ferroptotic antitumor therapy has been compromised by various intracellular antioxidants, particularly glutathione and thioredoxin. Both are cofactors of glutathione peroxide 4 (GPX4) that act against oxidative stress via catalyzing the reduction of lipid peroxides. It was postulated that tailored polymer micelles could enhance ferroptotic antitumor efficacy via diminishing glutathione and thioredoxin under hypoxia. The aim was to engineer hypoxia-responsive micelles for selective enhancement of ferroptotic cell death in solid tumor. The polymer contains hydrophilic poly(ethylene glycol) (PEG) that is linked by azobenzene linker with nitroimidazole-conjugated polypeptide. The tailored polymer could self-assemble into nanoscale micelles to encapsulate RAS-selective lethal small molecule 3, a covalent GPX4 inhibitor. Under hypoxia, the azobenzene moiety enabled PEG shedding and enhanced micelles uptake in 4T1 cells. Likewise, the nitroimidazole moiety was reduced by the overexpressed nitroreductase with reduced nicotinamide adenine dinucleotide phosphate (NADPH) as the cofactor, resulting in transient depletion of NADPH. This impaired both the glutathione and thioredoxin redox cycle, leading to diminished intracellular glutathione and thioredoxin. The selective potency of ferroptotic micelles in depleting NADPH, glutathione and thioredoxin was further verified in vivo in the 4T1 tumor xenograft mice model. This work highlights the role of hypoxia-responsive polymers in enhancing the potency of ferroptotic inducers against solid tumors without additional side effects to healthy organs.

Abstract
Radical thiol-ene chemistry has been demonstrated for a range of applications in peptide science, including macrocyclization, glycosylation and lipidation amongst a myriad of others. The thiol-ene reaction offers a number of advantages in this area, primarily those characteristic of "click" reactions. This provides a chemical approach to peptide modification that is compatible with aqueous conditions with high orthogonality and functional group tolerance. Additionally, the use of a chemical approach for peptide modification affords homogeneous peptides, compared to heterogeneous mixtures often obtained through biological methods. In addition to peptide modification, thiol-ene chemistry has been applied in novel approaches to biological studies through synthesis of mimetics and use in development of probes. This review will cover the range of applications of the radical-mediated thiol-ene reaction in peptide and protein science.

Robust and smart polypeptide-based nanomedicines for targeted tumor therapy. Adv Drug Deliv Rev 2020; 160:199-211.

Abstract
Nanomedicines based on synthetic polypeptides are among the most versatile and advanced platforms for tumor therapy. Notably, several polypeptide-based nanodrugs are currently under human clinical assessments. The previous (pre)clinical studies clearly show that dynamic stability (i.e. stable in circulation while destabilized in tumor) of nanomedicines plays a vital role in their anti-tumor performance. Various strategies have recently been developed to design dynamically stabilized polypeptide-based nanomedicines by e.g. crosslinking the nanovehicles with acid, reactive oxygen species (ROS), glutathione (GSH), or photo-sensitive linkers, inter-crosslinking between vehicles and drugs, introducing π-π stacking or lipid-lipid interactions in the nanovehicles, chemically conjugating drugs to vehicles, and forming unimolecular micelles. Interestingly, these robust and smart nanodrugs have demonstrated improved tumor targetability, anti-tumor efficacy, as well as safety profiles in different tumor models. In this review, representative strategies to robust and smart polypeptide-based nanomedicines for targeted treatment of varying malignancies are highlighted. The exciting development of dynamic nanomedicines will foresee further increasing clinical translation in the future.

Abstract
The chemotherapy toward glioblastoma (GBM) is severely challenged by blood-brain barrier and dose-limiting toxicity. Herein, we adopt brain delivery of Plk1 inhibitor volasertib (Vol), which is highly specific and presents low off-target toxicity, as a new means to treat GBM, for which angiopep-2-docked chimaeric polypeptide polymersome (ANG-CPP) was designed and prepared from poly(ethylene glycol)-b-poly(L-tyrosine)-b-poly(L-aspartic acid) for loading Vol to its watery interior via electrostatic interactions. ANG-CPP loaded with 13.9 wt% Vol (ANG-CPP-Vol) exhibited a small size of about 76 nm, superb colloidal stability (against dilution, serum and long-term storage), and enzyme-triggered drug release behavior (about 73% of Vol released within 8 h with proteinase K). In sharp contrast to free Vol, ANG-CPP-Vol induced complete G2/M cell cycle arrest in U-87 MG GBM cells giving 7.8-times better anti-tumor activity, prolonged circulation time and largely increased GBM enrichment. ANG-CPP-Vol effectively suppressed the growth of orthotopic U-87 MG GBM and significantly boosted mice survival rate. Importantly, ANG-CPP-Vol showed further reduced toxicity over free Vol. This great safety and remarkable efficacy of ANG-CPP-Vol renders it a high potential for treating GBM.

Abstract
The secondary structure formation of polypeptides not only governs folding and solution self-assembly but also affects the nucleophilic ring-opening polymerization of α-amino acid-N-carboxyanhydrides (NCAs). Whereby helical structures are known to enhance polymerization rates, β-sheet-like assemblies reduce the propagation rate or may even terminate chain growth by precipitation or gelation. To overcome these unfavorable properties, racemic mixtures of NCAs can be applied. In this work, racemic S-(ethylsulfonyl)-dl-cysteine NCA is investigated for the synthesis of polypeptides, diblock and triblock copolypept(o)ides. In contrast to the polymerization of stereoregular S-(ethylsulfonyl)-l-cysteine NCA, the reaction of S-(ethylsulfonyl)-dl-cysteine NCA proceeds with a rate constant of up to kp = 1.70 × 10-3 L mol-1 s -1 and is slightly faster than the enatiopure polymerization. While the polymerization of S-(ethylsulfonyl)-l-cysteine NCA suffers from incomplete monomer conversion and degrees of polymerization (DPs) limited to 30-40, racemic mixtures yield polypeptides with DPs of up to 102 with high conversion rates and well-defined dispersities (1.2-1.3). The controlled living nature of the ring-opening polymerization of S-(ethylsulfonyl)-dl-cysteine NCA thus enables the synthesis of triblock copolymers by sequential monomer addition. This methodology allows for precise control over DPs of individual blocks and yields uniform triblock copolymers with symmetric molecular weight distributions at a reduced synthetic effort.

Abstract
Commercial PEG-amine is of unreliable quality, and conventional PEG functionalization relies on esterification and etherification steps, suffering from incomplete conversion, harsh reaction conditions, and functional-group incompatibility. To solve these challenges, we propose an efficient strategy for PEG functionalization with carbamate linkages. By fine-tuning terminal amine basicity, stable and high-fidelity PEG-amine with carbamate linkage was obtained, as seen from the clean MALDI-TOF MS pattern. The carbamate strategy was further applied to the synthesis of high-fidelity multi-functionalized PEG with varying reactive groups. Compared to with an ester linkage, amphiphilic PEG-PS block copolymers bearing carbamate junction linkage exhibits preferential self-assembly tendency into vesicles. Moreover, nanoparticles of the latter demonstrate higher drug loading efficiency, encapsulation stability against enzymatic hydrolysis, and improved in vivo retention at the tumor region.

Abstract
Hydrogels are widely used for biomedical applications such as drug delivery, tissue engineering, or wound healing owing to their mimetic properties in relation to biological tissues. The generation of peptide-based hydrogels is a topic of interest due to their potential to increase biocompatibility. However, their usages can be limited when compared to other synthetic hydrogels because of their inferior mechanical properties. Herein, we present the synthesis of novel synthetic polypeptide-based interpenetrating network (IPN) hydrogels with enhanced mechanical properties. The polypeptide single network is obtained from alkyne functional polypeptides crosslinked with di, tri and tetra azide functional PEG by copper-catalysed alkyne-azide cycloaddition (CuAAC). Interpenetrating networks were subsequently obtained by loading of the polypeptide single network with PEG-dithiol and orthogonally UV-crosslinking with varying molar ratios of pentaerythritol tetraacrylate. The characteristics, including the mechanical strength (i.e. compressive strength (UCS), fracture strain (εbreak), and Young's modulus (E)) and cell compatibility (i.e. metabolic activity and Live/Dead of human Mesenchymal Stem Cells), of each synthetic polypeptide-based IPN hydrogel were studied and evaluated in order to demonstrate their potential as mechanically robust hydrogels for use as artificial tissues. Moreover, 1H NMR diffusometry was carried out to examine the water mobility (DH2O) within the polypeptide-based hydrogels and IPNs. It was found that both the mechanical and morphological properties could be tailored concurrently with the hydrophilicity, rate of water diffusion and 'swellability'. Finally it was shown that the polypeptide-based IPN hydrogels exhibited good biocompatibility, highlighting their potential as soft tissue scaffolds.

Abstract
Antimicrobial peptides (AMPs) are naturally occurring macromolecules made of amino acids that are potent broad-spectrum antibiotics with potential as novel therapeutic agents. This review aims to summarize the fundamental principles concerning the structure and mechanism of action of these AMPs, in order to guide the design of polymeric analogues that organic chemistry can generate. Among those simplified analogues, this review particularly focuses on those made of amino acids called polypeptide polymers: they are showing great potential by providing one of the best biomimetic and bioactive structures for further biomaterials science applications.

Abstract
Atomistic molecular dynamics (MD) simulations are carried out to examine the effect of molecular weight Mw (= 0.6, 0.86, 1.12, and 2.15 kDa) and pH (or equivalently, degree of ionization, α+ = 0, 50, and 100%) on the structure, state of hydration, and dynamics of linear and branched poly(ethylene imine) (PEI) chains in infinitely dilute salt-free aqueous solutions. It is found that the degree of ionization is the key factor determining the type of molecular conformation adopted by PEI, regardless of molecular architecture and chain length, resulting in a stable trans conformation for fully ionized solutions and in a stable gauche+/gauche- state for neutral or alternate ionized ones; in the latter case, a strong electrolyte behavior is verified for both linear and branched PEI. Linear PEI is observed to be significantly stiffer than branched PEI of the same molecular weight at 100% degree of ionization, but the effect subsides as the degree of ionization decreases. Also, linear PEI diffuses markedly slower than branched PEI of the same Mw. From the MD results, scaling exponents are deduced and reported for the conformation, solvent-accessible surface area, and dynamics of the two different PEI structures with Mw.

Abstract
Although several synthetic polypeptide-based nano-prodrugs (NPDs) have entered clinical trials for cancer treatment, achieving a highly effective production of the NPDs for clinical translation remains a challenge. Herein, we develop a typical preparation of pH/glutathione (GSH) dual-responsive glycopolypeptide analogue NPDs having a high drug capsulation/loading efficiency of ca. 93% and ca. 27% even based on ring-opening polymerization (ROP) of a novel and general furan-containing N-carboxyanhydride (NCA) monomer, which facilitates the Diels-Alder (D-A) side-chain functionalization by maleimide modified chemotherapy drug without using any reactive additives. High reactivity of the D-A reaction resulting in the high preparation efficiency of the NPDs is confirmed by 1H NMR and density functional theory (DFT) calculations. The self-assembled properties as well as the dual-responsiveness of the NPDs are systemically studied by particle size and zeta potential assay, transmission electron microscopy and drug-delivery dynamics. The cell uptake mechanism, intracellular drug distribution, in vitro/vivo antitumor activity evaluations and the main organ damages of the NPDs are all investigated. Our work can provide a good solution to solve the inefficient fabrication of the smart synthetic polypeptide-based micelles for cancer treatment by following this general and sophisticated platform.

Abstract
Employing natural-based renewable sugar and saccharide resources to construct functional biopolymer mimics is a promising research frontier for green chemistry and sustainable biotechnology. As the mimics/analogues of natural glycoproteins, synthetic glycopolypeptides attracted great attention in the field of biomaterials and nanobiotechnology. This review describes the synthetic strategies and methods of glycopolypeptides and their analogues, the functional self-assemblies of the synthesized glycopolypeptides, and their biological applications such as biomolecular recognition, drug/gene delivery, and cell adhesion and targeting, as well as cell culture and tissue engineering. Future outlook of the synthetic glycopolypeptides was also discussed.

Abstract
Polypeptide micelles are widely used as biocompatible nanoplatforms but often suffer from their poor structural stability. Unimolecular polypeptide micelles can effectively address the structure instability issue, but their synthesis with uniform structure and well-controlled and desired sizes remains challenging. Herein we report the convenient preparation of spherical unimolecular micelles through dendritic polyamine-initiated ultrafast ring-opening polymerization of N-carboxyanhydrides (NCAs). Synthetic polypeptides with exceptionally high molecular weights (up to 85 MDa) and low dispersity (Đ < 1.05) can be readily obtained, which are the biggest synthetic polypeptides ever reported. The degree of polymerization was controlled in a vast range (25-3200), giving access to nearly monodisperse unimolecular micelles with predictable sizes. Many NCA monomers can be polymerized using this ultrafast polymerization method, which enables the incorporation of various structural and functional moieties into the unimolecular micelles. Because of the simplicity of the synthesis and superior control over the structure, the unimolecular polypeptide micelles may find applications in nanomedicine, supermolecular chemistry, and bionanotechnology.

Abstract
Glycoproteins and their mimics are challenging to produce because of their large number of polysaccharide side chains that form a densely grafted protein-polysaccharide brush architecture. Herein a new approach to protein bioconjugate synthesis is demonstrated that can approach the functionalization densities of natural glycoproteins through oligosaccharide grafting. Global amino acid substitution is used to replace the methionine residues in a methionine-enriched elastin-like polypeptide with homopropargylglycine (HPG); the substitution was found to replace 93% of the 41 methionines in the protein sequence as well as broaden and increase the thermoresponsive transition. A series of saccharides were conjugated to the recombinant protein backbones through copper(I)-catalyzed alkyne-azide cycloaddition to determine reactivity trends, with 83-100% glycosylation of HPGs. Only an acetyl-protected sialyllactose moiety showed a lower level of 42% HPG glycosylation that is attributed to steric hindrance. The recombinant glycoproteins reproduced the key biofunctional properties of their natural counterparts such as viral inhibition and lectin binding.

Abstract
Polypeptide-derived copolymers have widely been exploited for drug/gene delivery due to their pendant functional groups and non-toxic degradation products. However, fabrication of polypeptide-based scaffolds for tissue engineering has seldom been reported. In this study, foamy poly(N ε -benzyl formateoxycarbonyl-L-Lysine) (PZL) and poly(N ε -benzyl formateoxycarbonyl-L-lysine-co-L-phenylalanine) (PZLP) scaffolds were successfully prepared by a combination of ring-opening polymerization of α-amino acid N-carboxyanhydride and negative porous NaCl templating approach. The physicochemical properties of these scaffolds including glass transition temperature, contact angle, compression modulus and degradation behavior were characterized. Both in vitro and in vivo biocompatibility of the scaffolds were evaluated by MC3T3-E1 cell culture and SD subcutaneous model, respectively. The results from live-dead staining, MTT and ALP activity assays indicated that PZL scaffolds were more conducive to the adhesion, proliferation and osteoblastic differentiation of MC3T3-E1 cells compared to PZLP scaffolds in the initial culture period due to their specific surface properties. While porous structure rather than surface properties of scaffolds played a decisive role in the later stage of cell culture. The results of in vivo studies including H&E, Masson's trichrome and CD34 staining further demonstrated that PZL scaffolds supported the ingrowth of microvessels than PZLP scaffolds due to their surface property difference. Collectively, PZL scaffolds displayed good biocompatibility and could be a promising candidate for tissue engineering application.

Abstract
The clinical success of polypeptides as polymeric drugs, covered by the umbrella term "polymer therapeutics," combined with related scientific and technological breakthroughs, explain their exponential growth in the development of polypeptide-drug conjugates as therapeutic agents. A deeper understanding of the biology at relevant pathological sites and the critical biological barriers faced, combined with advances regarding controlled polymerization techniques, material bioresponsiveness, analytical methods, and scale up-manufacture processes, have fostered the development of these nature-mimicking entities. Now, engineered polypeptides have the potential to combat current challenges in the advanced drug delivery field. In this review, we will discuss examples of polypeptide-drug conjugates as single or combination therapies in both preclinical and clinical studies as therapeutics and molecular imaging tools. Importantly, we will critically discuss relevant examples to highlight those parameters relevant to their rational design, such as linking chemistry, the analytical strategies employed, and their physicochemical and biological characterization, that will foster their rapid clinical translation.
