In conclusion, the findings demonstrated that 17-DMAG-loaded PCL/PEG nanofibers are more effectual than free 17-DMAG against A549 lung cancer cells via modulation of Hsp90 expression and inhibition of telomerase activity. Hence, the implantable 17-DMAG-loaded nanofibrous scaffolds might be an excellent tool for efficiently killing of the lung residual cancer cells and avoid the local cancer recurrence.

Publication date: Available online 20 July 2018Source: Chemico-Biological InteractionsAuthor(s): Rahul S. Kalhapure, Jwala RenukuntlaAbstractA new generation of the more effective polymeric micelle and nanoparticle drug delivery systems evolved due to the emergence of stimuli-responsive polymers. Among various stimuli, pH and temperature are most widely studied for enhanced drug release at the site of action. Researchers are focusing on dual (pH and temperature) responsive polymeric micelles and nanoparticles for controlled and enhanced drug release at the site of action. These dual responsive systems are mainly evaluated ...

Authors: Zhou Y, Li N, Qiu Z, Lu X, Fang M, Chen X, Ren L, Wang G, Ouyang P Abstract Triacontanol (TA, C30H62O), abundantly present in plant cuticle waxes and bee waxes, has been found to display promising anti-neoplastic potentials. As a long chain fatty alcohol, TA possesses limited aqueous solubility, which hinders its medicinal application. To overcome its solubility barrier, a polymer prodrug was synthesized through attaching TA to poly ethylene glycol (PEG), using succinic acid as a linker with bifunctional amide and ester bonds. Anti-neoplastic effects of PEG-TA were assessed in LoVo and MCF7 cells, anti-pro...

ConclusionWithin an evolving context where services are centralised, new therapies emerge and subsequently come off patent, our understanding of the value of cancer therapies continues to evolve. This has important implications for the evaluation of new therapies and broader policy initiatives in this area.

Publication date: 1 November 2018Source: Materials Science and Engineering: C, Volume 92Author(s): Marjan Ghorbani, Hamed HamishehkarAbstractThe clinical applications of anticancer drugs are restricted due to the incomplete delivery to the cancerous tissue and the numerous drug resistance mechanisms involved in malignant cells. In this regard, stimuli-responsive nanomaterials offer a promising prospect to deal with these concerns. In the present study, ternary responsive hybrid gold/nanogels (Au/NGs) were synthesized as a new nanoplatform to simultaneously carry two anticancer drugs, i.e., doxorubicin (DOX) and 6-mercaptop...

Publication date: 1 November 2018Source: Materials Science and Engineering: C, Volume 92Author(s): Yuanfang Huang, Ping Xie, Sheng-Tao Yang, Xuemei Zhang, Guangfu Zeng, Qian Xin, Xiao-Hai TangAbstractDrug delivery systems for doxorubicin (DOX) have attracted tremendous interest nowadays for the improved efficacy and/or reduced toxicity. Due to the aromatic structures and hydrophobic domains, carbon nanoparticle suspension injection (CNSI), a clinical applied reagent for lymph node mapping, strongly adsorbs DOX and holds great potential in cancer therapy. Herein, we evaluated the therapeutic effects of CNSI-DOX to establish...

In this study, novel molecularly imprinted polymer (MIP) microparticles containing methacryl polyhedral oligomeric silsesquioxane (M-POSS) were synthesized through the RAFT precipitation polymerization (RAFTPP) method using paclitaxel (PTX) as the templates. During the course of this investigation, methacrylic acid (MAA) was used as the functional monomer, while ethylene glycol dimethacrylate (EGDMA) was utilized as a cross-linker. The effects of different molar ratios of M-POSS on the microparticles were characterized. The obtained MIP microparticles were confirmed by FT-IR and TGA-DSC. The results of SEM showed regular s...
