Well-controlled Permeability for Effective Drug Delivery
The research involved the synthesis of three polymersomes with different hydrophobic chains, PEO43-b-P(CL45-stat-CTCL25), PEO43-b-P(CL108-stat-CTCL16), and PEO43-b-PCTCL4-b-PCL79. The process involved introduced crystalline PCL moiety as part of the membrane’s molecular structure via the synthesis of three polymersomes with different hydrophobic chains, PEO43-b-P(CL45-stat-CTCL25), PEO43-b-P(CL108-stat-CTCL16), and PEO43-b-PCTCL4-b-PCL79. The amorphous PCTCL moiety in the membranes resulted in a high permeability and a finely adjustable drug release rate. The mesoscopic dynamics simulations (MesoDyn), along with the doxorubicin releases tests, confirmed that membrane permeability was indeed related to membrane phase separation. The membrane phase separation technique, which was used to modify polymersomes, improved the programmed drug release rates. This is a significant improvement in the drug delivery field.
In biomedicine, the delivery of small molecules was based on membranes like polymersomes. The effectiveness and efficiency in drug delivery are therefore key factors when developing treatments for cancer, among other diseases. Although they have been extensively researched, and are a promising option for drug delivery vessels due to their homogeneity. This makes it difficult to release the drug. Recent research has focused on modifying and customizing the polymersome membranes for programmed release of small molecules to meet biomedical needs. This research is a continuation from previous efforts to overcome the high permeability caused by the amorphous polymersomes based on PCTCL. It will make it easier to deliver small molecules to a wider range of applications.
The importance of and use for medicines is expected to grow as the world population grows along with the longevity. This will have a longer-term impact on our ecosystem and health. There is an increasing need to support precision medicines and reduce the use of ineffective medicine which can burden patients, society, and environment over time. This research’s outcome, which is the improved capability of programmed release of drugs via modification of polymersomes meets this demand. (SDG 3 : Good Health and Well-being)
