Marigenol-concentrates comprising Taxol and/or Taxan esters as active substances

Area of Science:

• Pharmaceutical Chemistry
• Drug Delivery Systems
• Medicinal Chemistry

Background:

• Phytosteryl esters possess demonstrated antitumor and antiviral/virucidal properties.
• Challenges exist in formulating these compounds for optimal therapeutic delivery and efficacy.
• Existing formulations may lead to unwanted side effects and suboptimal dose-response relationships.

Purpose of the Study:

• To develop and test a novel Solubilization System for phytosteryl ester compounds.
• To create spontaneously dispersible concentrates enabling stable aqueous ultramicroemulsions.
• To enhance the bioavailability and bio-reactivity of active phytosteryl ester principles.

Main Methods:

• Formulation of spontaneously dispersible concentrates containing phytosteryl esters.
• Development of thermodynamically stable, aqueous ultramicroemulsions.
• Testing of the developed system for bioavailability and bio-reactivity.

Main Results:

• The Solubilization System successfully produced stable aqueous ultramicroemulsions.
• Outstanding bioavailability and bio-reactivity of phytosteryl ester compounds were achieved.
• Therapeutic use demonstrated a drastic reduction or absence of unwanted side effects.
• Optimization of the dose-efficacy relationship and improved drug safety were observed.

Conclusions:

• The novel Solubilization System offers a significant advancement in formulating phytosteryl esters.
• This formulation strategy enhances therapeutic potential by improving bioavailability and reducing side effects.
• The system provides a cost-effective approach to optimizing drug safety and efficacy.
