Nanosoft Polymers’s FITC-labeled polyesters were used in nanoparticles for codelivery of Paclitaxel and Everolimus for the treatment of breast cancer

Clinical studies examining the combination of paclitaxel (PTX) and everolimus (EVER), an mTOR inhibitor, have failed to result in significant improvements in efficacy and toxicity in patients with breast cancer (BC), relative to treatment with PTX alone. Recently, a research paper published in Molecular Pharmaceutics reported co-delivery of Paclitaxel and Everolimus by polymeric micelles at an optimal synergistic ratio to achieve specific, colocalized delivery of the combination therapy in BC cell lines. The nanoparticles were prepared from PLGA-PEG and PLGA-PEG-FITC (Nanosoft Polymers) had an average diameter of less than 100 nm and were capable of in vitro retention of the encapsulated PTX and EVER at the optimal synergistic molar ratio for over 7 days. The uptake of FITC-labeled NPs in SKBR3 cells was evaluated by flow cytometry, with approximately 41% of cells demonstrating detectable fluorescence after 24 h of exposure. The thorough and systematic approach used in this study to determine and evaluate a synergistic PTX:EVER ratio in conjunction with a potentially promising delivery vector for the drug combination could offer a future clinical benefit for patients with BC.   2018 Jun 14. doi: 10.1021/acs.molpharmaceut.8b00217.


Nanosoft Polymers’s lipids for tumor targeted delivery of pheophorbide a in vivo for cancer photodynamic therapy

Targeted drug delivery has been an important issue for tumor therapy including photodynamic therapy (PDT). Folate receptor (FA) is over-expressed on the surface of many human cancer cells.  Recently, a research published in Biochemical and Biophysical Research Communications (BBRC) has reported FA-targeted nanoparticles carrying a photosensitizer (PS) for PDT of cancer. The nanoparticles were prepared from DSPE-MPEG and  DSPE-PEG5K-folate (Nanosoft Polymers) . The nanoparticles were highlighted with 1) Folate-modified PLGA nanoparticles (FA-PLGA-Pba NPs) were developed with non-toxic materials. 2) FA-PLGA-Pba NPs were stable in aqueous condition for long time without aggregation. 3) FA-PLGA-Pba NPs killed cancer cells effectively upon laser irradiation, and showed superior tumor-targeting in vivo.  In vivo and ex vivo imaging showed high accumulation of FA-PLGA-Pba NPs in tumor site during 24 h after intravenous injection to MKN28 tumor-bearing mice model. These results demonstrate that our FA-PLGA-Pba NPs are useful for tumor-targeted delivery of PS for cancer treatment by PDT.  2018 Apr 6;498(3):523-528. doi: 10.1016/j.bbrc.2018.03.013.
