The primary objective of this project is to develop drug-loaded polymeric nanoparticles
suspended in a biocompatible gel for topical delivery of therapeutic agents commonly
employed in the treatment of ocular viral/bacterial ...
Novel targeted lipid prodrugs to improve cellular absorption of acyclovir and topical delivery to the eye via nanomicellar approach
(2013)
Biotinylated lipid prodrugs of acyclovir (ACV) were designed to target the
sodium dependent multivitamin transporter (SMVT) on the intestine and cornea to
facilitate ACV cellular transport. All the prodrugs were screened ...
Role of Membrane Transporters in Drug Delivery, Drug Disposition And Drug-Drug Interactions
(2014-08-28)
secondary aim of this investigation we developed novel pentablock (PB) copolymer nanoparticles of pazopanib for treatment of ocular neovascularization. Our results indicated that PB copolymer based drug delivery systems can serve as a platform technology...

(2015-05-22)
Saquinavir (SQV) is the first antiretroviral protease inhibitor approved by Food and
Drug Administration in the United States for the treatment of HIV infection due to its
potent anti-HIV activity. However, some unfavorable ...
Pentablock copolymers based controlled release formulations of small and macromolecules for ophthalmic applications
(University of Missouri--Kansas City, 2012)
