Optimization and Synthesis of Nano-Niosomes for Encapsulation of Triacontanol by Box–Behnken Design
Triacontanol is a long-chain primary alcohol derived from policosanol, known for its diverse biological activities, including functioning as a plant growth regulator and exhibiting anti-inflammatory and antitumoral effects. However, its application is limited due to its high hydrophobicity, resulting in poor absorption and reduced therapeutic effectiveness. A potential solution to this problem is the use of niosomes. Niosomes are carriers composed of non-ionic surfactants, cholesterol, charge-inducing agents, and a hydration medium. They are effective in encapsulating drugs, improving their solubility and bioavailability. The objective of this study was to optimize and synthesize nano-niosomes for the encapsulation of triacontanol. Niosomes were synthesized using a thin-film hydration method combined with ultrasonication, following a Box–Behnken design. Niosomes were characterized using various techniques including dynamic light scattering, Fourier-transform infrared spectroscopy (FTIR), confocal microscopy, high-resolution scanning electron microscopy, and transmission electron microscopy (TEM). Formulation 14 of niosomes achieved the desired size, polydispersity index (0.198 ± 0.008), and zeta potential (−31.28 ± 1.21). FTIR analysis revealed a characteristic signal in the 3400–300 cm−1 range, indicating intermolecular interactions due to a bifurcated hydrogen bond between cholesterol and S60. Confocal microscopy confirmed the presence of triacontanol through Nile Red fluorescence. TEM revealed the spherical structure of niosomes.
期刊介绍:
Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
