Chitosan-thioglycolic acid conjugate: an alternative carrier for oral nonviral gene delivery?

Ronny Martien, +4 more
- 01 Jul 2007 - 
TL;DR: Thiolated chitosan represents promising excipients for preparation DNA nanoparticles in nonviral gene delivery system and may improve the efficacy of oral gene delivery systems.
Journal ArticleDOI

Green and facile synthesis of MOF and nano MOF containing zinc(II) and benzen 1,3,5-tri carboxylate and its study in ibuprofen slow-release

Witri Wahyu Lestari, +3 more
- 15 Jan 2018 - 
TL;DR: In this article, the authors compared green synthetic methods in generating nano-scale and bio-based metal-organic frameworks (MOFs) containing biocompatible metal ion, i.e., zinc(II) and benzen 1,3,5-tri carboxylic acid (H3BTC) using electro- and sonochemicals method.
Journal ArticleDOI

Novel Self-Nano Emulsifying Drug Delivery System (SNEDDS) of andrographolide isolated from Andrographis paniculata Nees: Characterization, in-vitro and in-vivo assessment

Yandi Syukri, +3 more
- 01 Oct 2018 - 
TL;DR: In this paper, a preparation and characterization of andrographolide isolated from Andrographis paniculata Nees (AND)-loaded self-nano emulsifying drug delivery system (SNEDDS) was conducted to improve its oral dissolution and bioavailability.
Journal ArticleDOI

Thiolated chitosan nanoparticles: transfection study in the Caco-2 differentiated cell culture.

Ronny Martien, +3 more
- 30 Jan 2008 - 
TL;DR: Cross-linked thiolated chitosan nanoparticles have the potential to be used as a non-viral vector system for gene therapy and are found to exhibit higher stability toward degradation in gastric juices.
Journal ArticleDOI

Thiolated hydroxyethyl cellulose: Design and in vitro evaluation of mucoadhesive and permeation enhancing nanoparticles

Deni Rahmat, +5 more
- 01 Feb 2013 - 
TL;DR: HEC-cysteamine nanoparticles with free thiol groups in the range of 117-1548 μmol/g could be a promising excipient for nanoparticulate delivery systems for poorly absorbed drugs.
