Abstract
Chemotherapy is one of the available cancer treatments which has been successfully employed to prolong the survival of cancer patients. However, it remains a major challenge to develop effective chemotherapeutic agents by reducing off-target toxicity, improving bioavailability, and effectively prolonging blood circulation. The pH profile of tumor cells is abnormal to that of normal cells, making it a potential breakthrough for designing effective chemotherapeutic drug agents. Here, the pH-activatable charge-reversal supramolecular nanocarriers, named MI7-β-CD/SA NPs, were prepared through a simple and "green" constructive process. MI7-β-CD/SA NPs possess both pH-induced charge-reversal and disassembly properties that were exploited to investigate the loading, delivery, and pH-responsive controlled release of the antitumor compound celastrol (CSL). CSL@MI7-β-CD/SA NPs displayed low hemolysis, good biocompatibility, and targeted uptake. Furthermore, CSL@MI7-β-CD/SA NPs exhibited superior apoptosis rates against SMMC-7721 cell lines compared with CSL, when CSL@MI7-β-CD/SA NPs and CSL were administered at a mass concentration of 5.0 μg/mL, i.e., the CSL content in CSL@MI7-β-CD/SA NPs was relatively lower than that of intact CSL. We expected that MI7-β-CD/SA NPs featuring pH-triggered charge reversal could offer a promising controlled release strategy that would then facilitate the clinical conversion of antitumor drugs.

Abstract
Topoisomerase enzymes have shown unique roles in replication and transcription. These enzymes which were initially found in Escherichia coli have attracted considerable attention as target molecules for cancer therapy. Nowadays, there are several topoisomerase inhibitors in the market to treat or at least control the progression of cancer. However, significant toxicity, low solubility and poor pharmacokinetic properties have limited their wide application and these characteristics need to be improved. Nano-delivery systems have provided an opportunity to modify the intrinsic properties of molecules and also to transfer the toxic agent to the target tissues. These delivery systems leads to the re-introduction of existing molecules present in the market as novel therapeutic agents with different physicochemical and pharmacokinetic properties. This review focusses on a variety of nano-delivery vehicles used for the improvement of pharmacological properties of topoisomerase inhibitors and thus enabling their potential application as novel drugs in the market.

Abstract
Smart nano-carriers have attained great significance in the biomedical field due to their versatile and interesting designs with different functionalities. The initial stages of the development of nanocarriers mainly focused on the guest loading efficiency, biocompatibility of the host and the circulation time. Later the requirements of less side effects with more efficacy arose by attributing targetability and stimuli-responsive characteristics to nano-carriers along with their bio- compatibility. Researchers are utilizing many stimuli-responsive polymers for the better release of the guest molecules at the targeted sites. Among these, pH-triggered release achieves increasing importance because of the pH variation in different organ and cancer cells of acidic pH. This specific feature is utilized to release the guest molecules more precisely in the targeted site by designing polymers having specific functionality with the pH dependent morphology change characteristics. In this review, we mainly concert on the pH-responsive polypeptides and some interesting nano-carrier designs for the effective theranostic applications. Also, emphasis is made on pharmaceutical application of the different nano-carriers with respect to the organ, tissue and cellular level pH environment.

Abstract
Three-dimensional (3D) and Four-dimensional (4D) printing emerged as the next generation of fabrication techniques, spanning across various research areas, such as engineering, chemistry, biology, computer science, and materials science. Three-dimensional printing enables the fabrication of complex forms with high precision, through a layer-by-layer addition of different materials. Use of intelligent materials which change shape or color, produce an electrical current, become bioactive, or perform an intended function in response to an external stimulus, paves the way for the production of dynamic 3D structures, which is now called 4D printing. 3D and 4D printing techniques have great potential in the production of scaffolds to be applied in tissue engineering, especially in constructing patient specific scaffolds. Furthermore, physical and chemical guidance cues can be printed with these methods to improve the extent and rate of targeted tissue regeneration. This review presents a comprehensive survey of 3D and 4D printing methods, and the advantage of their use in tissue regeneration over other scaffold production approaches.

Abstract
Nanotechnology, focused on discovery and development of new pharmaceutical products is known as nanopharmacology, and one research area this branch is engaged in are nanopharmaceuticals. The importance of being nano has been particularly emphasized in scientific areas dealing with nanomedicine and nanopharmaceuticals. Nanopharmaceuticals, their routes of administration, obstacles and solutions concerning their improved application and enhanced efficacy have been briefly yet comprehensively described. Cancer is one of the leading causes of death worldwide and evergrowing number of scientific research on the topic only confirms that the needs have not been completed yet and that there is a wide platform for improvement. This is undoubtedly true for nanoformulations of an anticancer drug doxorubicin, where various nanocarrriers were given an important role to reduce the drug toxicity, while the efficacy of the drug was supposed to be retained or preferably enhanced. Therefore, we present an interdisciplinary comprehensive overview of interdisciplinary nature on nanopharmaceuticals based on doxorubicin and its nanoformulations with valuable information concerning trends, obstacles and prospective of nanopharmaceuticals development, mode of activity of sole drug doxorubicin and its nanoformulations based on different nanocarriers, their brief descriptions of biological activity through assessing in vitro and in vivo behavior.

Abstract
(Poly)peptide-polymer conjugates continue to garner significant interest in the production of functional materials given their composition of natural and synthetic building blocks that confer select and synergistic properties. Owing to opportunities to design predefined architectures and structures with different morphologies, these hybrid conjugates enable new approaches for producing micro- or nanomaterials. Their modular design enables the incorporation of multiple responsive properties into a single conjugate. This review presents recent advances in (poly)peptide-polymer conjugates for drug-delivery applications, with a specific focus on the utility of the (poly)peptide component in the assembly of particles and nanogels, as well as the role of the peptide in triggered drug release.

Abstract
Polyelectrolyte complexes (PECs) are self-assembling nano-sized constructs that offer several advantages over traditional nanoparticle carriers including controllable size, biodegradability, biocompatibility, and lack of toxicity, making them particularly appealing as tools for drug delivery. Here, we discuss potential application of PECs for drug delivery to the slightly acidic tumor microenvironment, a pH in the range of 6.5–7.0. Poly(l-glutamic acid) (En), poly(l-lysine) (Kn), and a copolymer composed of histidine-glutamic acid repeats ((HE)n) were studied for their ability to form PECs, which were analyzed for size, polydispersity, and pH sensitivity. PECs showed concentration dependent size variation at residue lengths of E51/K55 and E135/K127, however, no complexes were observed when E22 or K21 were used, even in combination with the longer chains. (HE)20/K55 PECs could encapsulate daunomycin, were stable from pH 7.4–6.5, and dissociated completely between pH 6.5–6.0. Conversely, the E51-dauno/K55 PEC dissociated between pH 4.0 and 3.0. These values for pH-dependent particle dissociation are consistent with the pKa’s of the ionizable groups in each formulation and indicate that the specific pH-sensitivity of (HE)20-dauno/K55 PECs is mediated by incorporation of histidine. This response within a pH range that is physiologically relevant to the acidic tumors suggests a potential application of these PECs in pH-dependent drug delivery.

Abstract
Nanomedicines are widely studied for intracellular delivery of cancer drugs. However, the relationship between intracellular drug concentrations and drug responses are poorly understood. In this study, cellular and nuclear concentrations of doxorubicin were quantified with LC/MS after cell exposure with free and liposomal doxorubicin (pH-sensitive and pegylated liposomes). Cellular uptake of pegylated liposomes was low (∼3-fold extracellular concentrations) compared with doxorubicin in free form and pH-sensitive liposomes (up to 280-fold extracellular concentrations) in rat glioma (BT4C) and renal clear cell carcinoma (Caki-2) cells. However, after the cell exposure with pegylated liposomes, intracellular doxorubicin was distributed into the nuclear compartment in both cell types. Despite high drug concentrations in the nuclei, Caki-2 cells showed strong resistance toward doxorubicin. A model was successfully built to describe PK/PD relationship between drug concentrations in nucleus and cytotoxic responses in BT4C cells. This model is the first step to link target site concentration of doxorubicin into its effect and can be a useful part of more comprehensive future in vivo PK/PD models.

Abstract
Poly(sebacic anhydride) (PSA) is a promising polymer for the production of drug delivery vehicles. The aim of this work is to study the effect of preparation parameters on the quality of the nanoparticles. In this study, doxorubicin (DOX)-loaded PSA nanocapsules were prepared by an emulsion method. Effects of factors such as type of organic solvent, co-solute (surfactant) and its concentration on drug-loading efficiency, particle size and size distribution, morphology and release profile were examined to gain insight in the preparation and stability of nanostructures. Particles with sizes in the range of 218-1198 nm were prepared. The smallest particles with a narrow size distribution were prepared by using polyvinyl alcohol as a co-solute and dichloromethane as a solvent. Efficiency and intracellular release of doxorubicin from the formulated particles were studied on MDA-MB-231 cells. It was observed that DOX-loaded PSA particles can diffuse into the cells and intracellular antitumour activity is directly related to the released amount of drug from the PSA nanocapsules.
