Bexarotene prodrugs: Targeting through cleavage by NQO1 (DT-diaphorase)
摘要:
Bexarotene, a retinoid X receptor (RXR) agonist, is being tested as a potential disease modifying treatment for neurodegenerative conditions. To limit the peripheral exposure of bexarotene and release it only in the affected areas of the brain, we designed a prodrug strategy based on the enzyme NAD( P) H/quinone oxidoreductase (NQO1) that is elevated in neurodegenerative diseases. A series of indolequinones (known substrates of NQO1) was synthesized and coupled to bexarotene. Bexarotene-3(hydroxymethyl)-5-methoxy-1,2-dimethyl-1H-indole-4,7-dione ester 7a was cleaved best by NQO1. The prodrugs are not cleaved by esterase. (C) 2014 Elsevier Ltd. All rights reserved.

The invention relates generally to pyrrolobenzodiazepine monomer and dimer prodrugs having a glutathione-activated disulfide prodrug moiety, a DT-diaphorase-activated quinone prodrug moiety or a reactive oxygen species-activated aryl boronic acid or aryl boronic ester prodrug moiety. The invention further relates to pyrrolobenzodiazepine prodrug dimer-antibody conjugates.
