  Lipophilic amines as potent inhibitors of N-acylethanolamine-hydrolyzing acid amidase

  摘要：

  N-Acylethanolamines (NAEs) including N-arachidonoylethanolamine (anandamide) and N-palmitoylethanolamine are endogenous lipid mediators. These molecules are degraded to the corresponding fatty acids and ethanolamine by fatty acid amide hydrolase (FAAH) or NAE-hydrolyzing acid amidase (NAAA). Lipophilic amines, especially pentadecylamine (2c) and tridecyl 2-aminoacetate (11b), were found to exhibit potent NAAA inhibitory activities (IC50 = 5.7 and 11.8 mu M), with much weaker effects on FAAH. These simple structures would provide a scaffold for further improvement in NAAA inhibitory activity. (C) 2012 Elsevier Ltd. All rights reserved.

  Anchor Dependency for Non-Glycerol Based Cationic Lipofectins: Mixed Bag of Regular and Anomalous Transfection Profiles

  摘要：

  Although detailed structure activity, physicochemical and biophysical investigations in probing the anchor influence in liposomal gene delivery have been reported for glycerol-based transfection lipids, the corresponding investigation for non-glycerol based simple monocationic transfection lipids have not yet been undertaken. Towards this end, herein, we delineate our structure - activity and physicochemical approach in deciphering the anchor dependency in liposomal gene delivery using fifteen new structural analogues (lipids 1 - 15) of recently reported nonglycerol based monocationic transfection lipids. The C-14 analogues in both series 1 (lipids 1 - 6) and series 2 (lipids 7-15) showed maximum efficiency in transfecting COS-1 and CHO cells. However, the C-12 analogue of the ether series (lipid 3) exhibited a seemingly anomalous behavior compared with its transfection efficient C-10 and C-14 analogues (lipids 2 and 4) in being completely inefficient to transfect both COS-1 and CHO cells. The present structure - activity investigation also convincingly demonstrates that enhancement of transfection efficiencies through incorporation of membrane reorganizing unsaturation elements in the hydrophobic anchor of cationic lipids is not universal but cell dependent. The strength of the interaction of lipids 1 - 15 with DNA was assessed by their ability to exclude ethidium bromide bound to the DNA. Cationic lipids with long hydrophobic tails were found, in general, to be efficient in excluding EtBr from DNA. Gel to liquid crystalline transition temperatures of the lipids was measured by fluorescence anisotropy measurement technique. In general (lipid 2 being an exception), transfection efficient lipids were found to have their mid transition temperatures at or below physiological temperatures (37degreesC).
