Summary
This study developed novel curcumin-loaded micelles using mPEG-PCL, improving curcumin delivery for potential cancer treatment. The micelles demonstrated high encapsulation efficiency and sustained drug release, overcoming curcumin
Area of Science:
- Nanotechnology in drug delivery
- Polymer science for biomedical applications
- Cancer therapeutics research
Background:
- Curcumin exhibits potent anticancer properties but faces clinical limitations due to poor bioavailability and rapid metabolism.
- Developing effective drug delivery systems is crucial to enhance curcumin's therapeutic efficacy.
- Micellar systems offer a promising approach to encapsulate hydrophobic drugs like curcumin.
Purpose of the Study:
- To synthesize a novel micellar delivery system using monomethoxypoly(ethylene glycol)-poly(ε-caprolactone) (mPEG-PCL) for curcumin.
- To evaluate the encapsulation efficiency and in vitro release profile of curcumin from the developed mPEG-PCL micelles.
Main Methods:
- Curcumin was encapsulated into mPEG-PCL micelles via a single-step nano-precipitation method.
- mPEG-PCL copolymers were synthesized and characterized using HNMR, FTIR, DSC, and GPC.
- Curcumin-loaded micelles (Cur/mPEG-PCL) were characterized by dynamic light scattering (DLS) and atomic force microscopy (AFM).
Main Results:
- Successfully formed smooth, spherical curcumin-loaded micelles with an encapsulation efficiency of 88 ± 3.32%.
- Atomic force microscopy confirmed spherical micelles with an average size of 73.8 nm.
- In vitro studies demonstrated a remarkably sustained release profile of curcumin from the entrapped micelles.
Conclusions:
- The successful formulation of curcumin-loaded mPEG-PCL micelles was achieved.
- These curcumin-loaded mPEG-PCL micelles represent a potential effective strategy for future cancer treatment.
- The sustained release profile suggests improved therapeutic potential for curcumin delivery.

314
Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

231
Drug release from modified-release dosage forms is designed to achieve specific therapeutic effects by controlling the rate and extent of drug release. The classification of these drug release systems is based on key pharmacokinetic assumptions: drug disposition follows first-order kinetics, drug release is the rate-limiting step in absorption, and the released drug is rapidly and completely absorbed.There are four major models of drug release patterns. The first model is the slow zero-order...

Delayed-release drug delivery systems are specialized pharmaceutical formulations designed to postpone the release of active compounds until the drug reaches a specific region of the gastrointestinal (GI) tract, typically the intestine. These systems are essential for drugs that may cause gastric irritation, are unstable in acidic environments, or need to exert therapeutic effects locally in the intestinal or colonic regions.The core feature of delayed-release systems is the use of enteric...

Micelle formation is an intricate process that hinges on the properties of amphiphilic or amphipathic molecules and the conditions of the system in which they are found. Amphiphilic molecules, which have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts, play a critical role in this process.In aqueous environments, these molecules arrange themselves such that their hydrophilic heads are turned towards the water phase, while their hydrophobic tails are oriented away...

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...

Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...
