Using nanoparticles for the delivery of small molecules in anticancer therapy is a rapidly growing area of research. Nanoparticles can be used in targeted drug delivery to improve the aqueous solubility of poorly soluble drugs and the bioavailability of drugs and thus are widely applied in therapeutic uses. CD Bioparticles is experienced in providing small molecule drug carriers such as polymeric nanoparticles, liposomes, viral-like nanoparticles for your need.
Small Molecule Drugs Introduction
Drug delivery systems that deliver the small molecule drugs in a manner that meets the therapeutic need of the patient while eliciting fewer adverse effects are becoming increasingly common. In recent years, the development of therapeutic nanoparticles for the delivery of small molecule anticancer agents has received great attention from the medical research community. Many small molecules have been employed for different medical therapeutic uses over the years with great success. From the most dreaded diseases like cancer, diabetes, epilepsy, obesity to more humane ailments of cough, fever, cold amongst others.
Small molecule drugs are low but variably specific (predominantly) organic substances with well-defined structures and molecular weight less than 900 Daltons that help regulate biological processes mainly by metabolic degradation. The small molecules can reach almost any desired destination in the body because of their tiny size. Their small structure and chemical composition often also help them to easily penetrate cell membranes. Several small molecule drugs including paclitaxel, doxorubicin, and 5-fluorouracil have been successfully formulated using nanotechnology.
The advantages of using nanoparticles for delivering small molecule drugs are displayed as follows:
Owing to their flexible characteristics, nanoparticles can be fabricated from biodegradable, absorbable and biocompatible polymeric materials. Therapeutic nanoparticles can be formulated with several materials such as lipids (liposomes), polymers (macromolecules, micelles or dendrimers) and viruses (viral-like nanoparticles) with distinct characteristics.
