  Effect of cosolvent on the lateral order of spontaneously formed amphiphilic amide two-dimensional crystallites at the air-solution interface

  摘要：

  At low temperature (5-12-degrees-C), uncompressed films of insoluble amphiphilic molecules C19H39X, where the head group X contains one (CONH2, 1) or two (CONHC2H4CONH2, 2) amide groups, spontaneously form two-dimensional (2D) crystalline clusters over aqueous subphases containing soluble amide or carboxylic acid molecules. These crystallites were detected and their structures were studied using grazing incidence X-ray diffraction (GID). In the presence of subphases containing carboxylic acid (RCO2H, R = H, CH2Cl) at sufficiently high concentrations, a loss of diffraction signal was observed for 1, while amide and less concentrated acid subphases did not show such a destructive effect. The effect of the subphase solute molecules was understood in terms of the different ways in which the solutes hydrogen bond to the amide head groups of the amphiphiles. Both amide and acid solute molecules can form hydrogen-bonded cyclic dimers with the amide head groups. With an amide subphase, such dimers lead to an extension of the hydrogen-bonding network of the crystallites, and thus enhance its stability, but acid molecules may also bind to the monolayer at low concentrations with less than full occupancy. At high acid concentration, and thus more extensive formation of cyclic dimers between carboxylic acid and amphiphilic amide molecules, repulsive interactions between lone pair electrons on oxygen atoms of bound acid molecules inhibit formation of ordered arrays of these dimers and lead to a lack of diffraction signal. In 2, the second amide group strengthens the crystallites to the extent that there is no decrease in crystallinity over a 1 M formic acid subphase. The shape of the intensity profiles of the Bragg rods and the specular X-ray reflectivity measurements of 2 indicate formation of molecular trilayers.

  结构，超分子组织和相行为的ň酰基-β-丙氨酸：哺乳动物大脑成分的结构同源ñ -acylglycine和ñ酰基氨基丁酸

  摘要：

  Ñ酰基-β-丙氨酸（一个Nabas）是结构同源物Ñ -acylglycines（唠叨）和Ñ酰基-γ氨基酸（NAGABAs），和非手性异构体Ñ -acylalanines，这些都是存在于哺乳动物的脑和其他组织和调节具有各种功能的生物受体的活性。在本研究中，我们合成并表征了一系列带有饱和酰基链的NABA（n = 8-20），并研究了它们的超分子组织和热致相行为。在差示扫描量热（DSC）研究中，大多数NABA在干态主链熔融相变之前以及与水水合时都会发生一两个次要的过渡，但在与缓冲液水合时仅会发生一个过渡（ pH 7.6）。从DSC研究获得的跃迁焓（ΔH t）和熵（ΔS t）显示出在干燥状态和缓冲液水合时对链长的线性依赖性，而在用水水合时观察到奇偶变化。N-月桂酰-β-丙氨酸（NLBA）和N的晶体结构在P21 / c空间群的单斜系统中解决了-肉豆蔻酰基-β-丙氨酸（NMBA）问题。NLBA和NMB

• Mixed monolayers for the design of structured surfaces to induce oriented 3-D crystallization

  Mixed monolayers containing two different amphiphiles C19H39CONHCH2CH2CO2H (A) and C19H39CONH2 (B) were designed in order to form a two-dimensional (2-D) crystalline solid solution in which the A-type molecules form domains within the sea of B-type molecules. A ''continuous'' 2-D arrangement of the aliphatic chains was expected, driven by the amide hydrogen bonding requirement; a tendency for the formation of the embeded A-type domains should be provided by the interactions between the -CH2CH2CO2H head group moieties. The mixed monolayers served to promote the oriented nucleation of silver propionate 3-D crystals attached at the monolayer-solution interface. Only the A-type domains induced silver propionate crystallization whereas the B-type domains were essentially inert. The mixed A + B monolayers were found to be efficient nucleators down to a 1:10 molar ratio, providing proof for the existence of A-type domains. Additional information such as the structure and ion-binding properties of the mixed monolayers was furnished by specular X-ray reflectivity and grazing incidence X-ray diffraction using synchrotron radiation.

  Inhibition of the farnesylation of ras proteins has been identified as a promising target in tumor therapy. Only a few farnesyltransferase inhibitors are bisubstrate analogues displaying features of both substrates, the farnesylpyrophosphate and the C-terminal CAAX-tetrapeptide sequence of the res protein. These known bisubstrate analogues consist of an AAX-tripeptide and a farnesyl residue connected through various linkers. We have developed a class of novel compounds that mimic a bisubstrate inhibitor structure and that differ from the known ones by lacking peptidic or farnesylic substructures. Long chain fatty acids and aryl-substituted carboxylic acids were used as farnesyl surrogates. These structures were linked to isoleucine amide, benzoic acid amide, N-substituted aminobenzenesulfonamides and N-alpha-aryl-substituted methionine derivatives, respectively, which function as AA- or AAX-mimetics.

  Strong hydrogen bonding interactions between COOH groups of the molecules from opposite leaflets as well as NH⋯O hydrogen bonds between the amide groups from adjacent molecules in the same leaflet as well as dispersion interactions between the acyl chains stabilize the bilayer structure. The d-spacings calculated from powder X-ray diffraction studies showed odd-even alteration with odd-chain length compounds
