  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).

  A rewritable optical information recording medium including a recording layer composed of an organic dye film is provided, in which recording and erasing information can be performed reversibly by laser light irradiation. A rewritable optical information recording medium including at least one organic dye film which is substantially made of only at least one kind of organic dye compounds as a recording film is provided. The recording and erasure of information are performed by a reversible physical change of the organic dye film substance caused by laser light irradiation. Specifically, data recording is performed by a physical change locally caused by the irradiation of recording laser light, data reproduction is performed by detecting change in intensity of returned light of reproducing laser light having less power than the recording laser light, and data erasure is performed by applying at least once continuous light or pulse light having laser power more than the reproducing laser light and less than the recording laser light. The physical change is a change in shape.

  secondary amines with long chains containing ether bonds were synthesized by a three-step protection–etherification–deprotection process from diethanolamine. The optimum reaction conditions were examined. This method has the advantages of simplicity, low cost, and high yield. Furthermore, some new downstream products (diglycolamides) were prepared from the ether-containing long-chain secondary amines as reactants
