“…The effectiveness and biodistribution of injectable amphiphilic cyclodextrin nanoparticles containing paclitaxel were examined in their research. The findings demonstrated that nanoparticles inhibited tumor development, had antitumoral effects earlier than the medication solution, and did not accumulate in the heart and lungs . According to different research, it was claimed that finding substances that could boost susceptibility to conventional chemotherapeutic drugs is becoming more and more popular.…”

There is a growing appeal for engineering drug delivery systems for controlled and local drug delivery. Conjugation of antibodies on the nanocarriers for targeted chemotherapeutic drugs has always been one of the main techniques. This work aims to develop a polycaprolactone/chitosan electrospun mat incorporated with paclitaxel/Fe 3 O 4 -loaded niosomes (SPNs) decorated with trastuzumab (TbNs) for cancer therapy. SPNs and TbNs were analyzed by DLS, zeta potential, scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectroscopy. Fabricated mats with distinct concentrations of TbNs were classified into four groups (G0 (0), G1 (1), G2 (2.5), and G3 (5%)) and were studied physicochemically, mechanically, and biologically. Paclitaxel release was also studied for 7 days under an alternative magnetic field (AMF). The optimized mat was nominated for an in vivo study to evaluate its tumor growth inhibition. Based on the results, the TbNs had a spherical core and shell morphology with a smooth surface. The zeta potential and the mean size of TbNs were equal to −14.7 mV and 221 nm. TbNs did not affect the morphology and quality of nanofibers, but in general, the presence of TbNs increased the elastic modulus, water uptake, and degradation. Regarding the release study, AMF showed a significant increase in accelerating paclitaxel release from mats, and most releases belonged to the mat with 5% of TbNs. Results from the in vivo study showed the effective and synergistic effects of AMF on drug release and significant tumor growth inhibition. To summarize, the proposed nanocarrier under AMF can be a good candidate for cancer therapy.

“…At the end of 72 hours of incubation, there was a significant decrease in cell viability for CS-(6-O-capro-β-CD) and poly-β-CD-C6 derivatives in the drug solution + blank nanoparticle formulation groups compared to the drug solution in 3D HT29 spheroids. Again, it was observed that blank nanoparticles caused a significant decrease in cell viability in 3D cell studies compared to the control group [ 55 , 64 ]. The reduction in cell viability for the blank poly-β-CD-C6 derivative was even higher than for the group that was treated with the drug solution.…”

Colorectal cancer (CRC) is the third most diagnosed cancer type globally and ranks second in cancer-related deaths. With the current treatment possibilities, a definitive, safe, and effective treatment approach for CRC has not been presented yet. However, new drug delivery systems show promise in this field. Amphiphilic cyclodextrin-based nanocarriers are innovative and interesting formulation approaches for targeting the colon through oral administration. In our previous studies, oral chemotherapy for colon tumors was aimed and promising results were obtained with formulation development studies, mucin interaction, mucus penetration, cytotoxicity, and permeability in 2D cell culture, and furthermore in vivo antitumoral and antimetastatic efficacy in early and late-stage colon cancer models and biodistribution after single dose oral administration. This study was carried out to further elucidate oral camptothecin (CPT)-loaded amphiphilic cyclodextrin nanoparticles for the local treatment of colorectal tumors in terms of their drug release behavior and efficacy in 3-dimensional tumor models to predict the in vivo efficacy of different nanocarriers. The main objective was to build a bridge between formulation development and in vitro phase and animal studies. In this context, CPT-loaded polycationic-β-cyclodextrin nanoparticles caused reduced cell viability in CT26 and HT29 colon carcinoma spheroid tumors of mice and human origin, respectively. In addition, the release profile, which is one of the critical quality parameters in new drug delivery systems, was investigated mathematically by release kinetic modeling for the first time. The overall findings indicated that the strategy of orally targeting anticancer drugs such as CPT with positively charged poly-β-CD-C6 nanoparticles to colon tumors for local and/or systemic efficacy is a promising approach.

The physicochemical properties (size, shape, zeta potential, porosity, elasticity, etc.) of nanocarriers influence their biological behavior directly, which may result in alterations of the therapeutic outcome. Understanding the effect of shape on the cellular interaction and biodistribution of intravenously injected particles could have fundamental importance for the rational design of drug delivery systems. In the present study, spherical, rod and elliptical disk-shaped PLGA nanoparticles were developed for examining systematically their behavior in vitro and in vivo. An important finding is that the release of the encapsulated human serum albumin (HSA) was significantly higher in spherical particles compared to rod and elliptical disks, indicating that the shape can make a difference. Safety studies showed that the toxicity of PLGA nanoparticles is not shape dependent in the studied concentration range. This study has pioneering findings on comparing spherical, rod and elliptical disk-shaped PLGA nanoparticles in terms of particle size, particle size distribution, colloidal stability, morphology, drug encapsulation, drug release, safety of nanoparticles, cellular uptake and biodistribution. Nude mice bearing non-small cell lung cancer were treated with 3 differently shaped nanoparticles, and the accumulation of nanoparticles in tumor tissue and other organs was not statistically different (p > 0.05). It was found that PLGA nanoparticles with 1.00, 4.0 ± 0.5, 7.5 ± 0.5 aspect ratios did not differ on total tumor accumulation in non-small cell lung cancer.
