[Display omitted] • l -Type amino acid transporter 1 (LAT1) can deliver drugs into the brain parenchyma. • Non-steroidal anti-inflammatory drugs (NSAIDs) could inhibit neuroinflammation. • Novel LAT1-utilizing ester prodrugs of 4 NSAIDs was synthesized and evaluated. • Prodrugs were uptaken into microglia/astrocytes and inhibited PGE 2 production. • Prodrugs were bioconverted by CES and other enzymes with varable rates. Non-steroidal anti-inflammatory drugs (NSAIDs) can have protective effects in the brain by inhibition of cyclooxygenases (COX). However, the delivery into the brain across the blood–brain barrier (BBB) and particularly into the brain parenchymal cells is hindered. Therefore, in the present study, we developed four l -type amino acid transporter 1 (LAT1)-utilizing prodrugs of flurbiprofen, ibuprofen, naproxen, and ketoprofen, since LAT1 is expressed on both, the BBB endothelial cells as well as parenchymal cells. The cellular uptake and utilization of LAT1 by novel prodrugs were studied in mouse cortical primary astrocytes and immortalized microglia (BV2), and the release of the parent NSAID in several tissue and cell homogenates. Finally, the effects of the studied prodrugs on prostaglandin E 2 (PGE 2) production and cell viability were explored. The gained results showed that all four prodrugs were carried into their target cells via LAT1. They also released their parent NSAIDs via carboxylesterases (CES) and most likely also other un-identified enzymes, which need to be carefully considered when administrating these compounds orally or intravenously. Most importantly, all the studied prodrugs reduced the PGE 2 production in astrocytes and microglia after lipopolysaccharide (LPS)-induced inflammation by 29–94% and without affecting the cell viability with the studied concentration (20 µM).
