Supramolecular Gels for Self-Delivery Applications

Partho Dastidar
Professor and Head

A conventional drug delivery system requires a delivery vehicle that is usually made up of polymer, micelles, vesicles etc. However, cytotoxicity of the vehicle, drug loading into the vehicle and its release into the affected site etc. are some of the major challenges in drug delivery research. A new approach is being proposed wherein a drug molecule is converted into supramolecular gel which can then be applied to the affected site topically (both hydro- and organogels) or subcutaneously (hydrogels) thereby getting rid of the vehicle and delivering the drug itself (self-delivery).

By exploiting the lessons learnt in our decade long endevour in designing supramolecular gelators based on supramolecular synthon rationale, we have recently undertaken an ambitious drug delivery research project that aims at developing drug based supramolecular gelators for self-delivery applications. This talk will highlight our recent efforts in converting non-steroidal-anti-inflammatory-drugs (NSAIDs) into supramolecular gelators and their applications both in vitro and in vivo.
