NSP’s Polymer were used in a patent for formulation of insoluble camptothecin compound with double core-shell structure

Recently, An patent (US20180369231A1) published by  SNBioScience Inc. has invented a drug delivery system having a double core-shell structure and, specifically, to a double nano-drug delivery system having an inner core-shell containing a poorly soluble camptothecin compound and a water-soluble camptothecin compound inside and an amphiphilic polymer shell, and to a manufacturing method therefor. The double core-shell structured particles manufactured by the present invention form very stable particles and show a mono-distribution of particles before and after freeze-drying. The particles of the present invention show excellent results compared with existing monolayer micelles in animal efficacy tests and pharmacokinetic tests, and do not use a surfactant causing hypersensitivity, and thus the use of the particles of the present invention can provide a pharmaceutical composition or a drug delivery system platform, which are safe for the human body.  NSP’s polymers were used in the formulation.

NSP’s DSPE-PEG-Mal were used to develop MMP-2-Controlled Transforming Micelles for Heterogeneic Targeting and Programmable Cancer Therapy

Nanoparticle (NP)-based tumor theranostics have ushered in new opportunities for personalized nanomedicine due to their rational design and functionalization. Through the active-peptide-functionalization,  a research group developed a nanoscale micelles system (named HEKM) which consists of tumor microenvironment-regulated shape-changing with specific recognition abilities for enhanced cellular targeting, internalization and therapy of heterogeneic tumors. As a result, HEKMs could recognize and bind the tumor heterogeneity marker EGFR-HER2 complex, which led to an enhanced tumor targeting effect. In particular, HEKMs could self-assemble into nanorods under normal physiological conditions while transform into nanospheres in the tumor extracellular microenvironment by a sensitive response to matrix metalloproteinase-2 (MMP-2). The nanorods could prolong the blood circulation time while the nanospheres could accelerate tissue penetration in tumors. In vivo dual-modal targeted imaging was realized by FRET-fluorophore conjugation and gadolinium loading in HEKMs. Tumor cell apoptosis was achieved by proapoptotic element integration. The in vitro and in vivo studies both demonstrated that these rationally designed, shape-changing and targeting micelles could achieve maximized drug efficacy and minimum side effects.
