NSP Products In Literature

NSP’s functional DSPE-PEG-Folate was used for folate recepotr-targeting nanocomplex to enhance the cytotoxicity, efficacy, and selectivity of antiancer leaf extract.

Nanomedicine holds great potential for drug delivery to achieve more effective and safer cancer treatment. Recently, one research group in Japan developed a folate receptor-targeting nanocomplex which carries alcoholic extract of Withania somnifera leaves (i-Extract) that has selective cancer cell killing activity,   suspends well in water and possesses enhanced selective anticancer activity in both in vitro and in vivo assays. Comparative analyses of folate receptor (FR)-positive and -negative cells revealed that FRi-ExNC caused a stronger decrease in Cyclin D/Cdk4 and anti-apoptotic protein Bcl-2, as well as a higher increase in the growth arrest regulating protein p21WAF1 and pro-apoptotic protein PARP-1, in FR-enriched cancer cells. The results demonstrate that FRi-ExNC could be a natural source-based nanomedicine for targeted cancer therapy. NSP’s DSPE-PEG-Folate was used to construct the nanocomplex for folate receptor-targeting. Front. Oncol., 04 July 2019 | https://doi.org/10.3389/fonc.2019.00602.

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.
