Preparation and Characterization of Thymoquinone Nanoparticles Pegylated as Drug Delivery System

Abstract

Objective: Thymoquinone is a main component of Black Cumin (Nigella sativa Linn.) with various pharmacological activities, but has poor stability and bioavailability. The purpose of this study was to carry out the preparation and characterization of timoquinone nanoparticles PEGylation.
 Methods: The Thymoquinone nanoparticles (TQ-NP) were made with PEGylation using PEG 6000 with the concentrations on each preparation of 3 mM (A), 4 mM (B), and 5 mM (C) then were evaluated by the parameter of yield percentage Entrapment Efficiency (EE) and Drug Loading (DL), drug release, size and distribution particle, morphological analysis and Fourier Transform-Infrared spectrophotometer (FTIR).
 Results: Thymoquinone nanoparticle was PEGylated with PEG 6000 has the highest efficiency entrapment of 99.9718±0.029% in formula A, with the capacity of drug loading 0,66%. Formulation A release 99.9718±0.029% of Thymoquinone at 50 minutes. The morphological observations with Scanning Electron Microscope (SEM) showed spherical nanoparticles morphology.

 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

“…The time taken for THQ:HPβCD to fully dissolve was over 2 h even when the loading was reduced to 5% (w/v). These results are comparable to published data into the complexation of THQ with HPβCD, however the present studies utilized various excipients which are novel to this application [37][38][39][40].…”
