In situ blood–brain barrier permeability of a C-10 paclitaxel carbamate
摘要:
We report the synthesis and blood-brain barrier (BBB)-permeability of (14)C-CNDR-29, a paclitaxel C-10 carbamate derivative shown to be devoid of P-glycoprotein (Pgp)-interactions, in an in situ mouse brain perfusion model, in comparison with (14)C-paclitaxel. The results presented reveal a 3- to 4-fold higher BBB-permeability for the C-10 modified taxane compared to paclitaxel. These results support the notion that circumvention of Pgp-mediated efflux can lead to higher BBB-permeability. Further studies however are needed to evaluate the therapeutic potential of the C-10 carbamates paclitaxel derivatives for the treatment of CNS diseases. (C) 2008 Elsevier Ltd. All rights reserved.

N-Acylethanolamines, including N-palmitoyl-ethanolamine (PEA), are hydrolyzed to the corresponding fatty acids and ethanolamine by fatty acid amide hydrolase (FAAH). Recently, N-acylethanolamine-hydrolyzing acid amidase (NAAA) was identified as being able to specifically hydrolyze PEA. In order to find selective and effective inhibitors of this enzyme, we synthesized and screened several amides, retroamides, esters, retroesters and carbamates of palmitic acid (1-21) and esters with C15 and C17 alkyl chains (22-27). Cyclopentylhexadecanoate (13) exhibited the highest inhibitory activity on NAAA (IC50 = 10.0 mu M), without inhibiting FAAH up to 50 mu M. Compound 13 may become a useful template to design new NAAA inhibitors. (C) 2009 Elsevier Ltd. All rights reserved.
