Direct evidence for the importance of hydrophobic mismatch for cell membrane recognition
摘要:
In this Letter, we describe the synthesis of amphiphilic oligo(p-phenylene)s from 31 to 44 Angstrom length and delineate the interaction of these rigid-rod molecules with lipid bilayers using fluorescence quenching methods. The results demonstrate high importance of hydrophobic mismatch for selective cell membrane recognition by rigid-rod molecules. (C) 1999 Elsevier Science Ltd. All rights reserved.

The invention relates to nanoparticles made from organometallic hybrid materials made from iron carboxylates, used for example as contrast agents. The particles can also be used for the encapsulation and vectoring of molecules of interest such as active3 pharmaceutical agents, cosmetically interesting compounds and markers. Apart from the intrinsic properties thereof for imaging, said nanoparticles give good results in terms of capacity for loading with medicaments and in biocompatibility.

Ester-linked, crystalline, porous, covalentorganicframeworks (COFs) have been synthesized and structurally character-ized. Transesterification reactions between di-topic 2-pyridinyl aromatic carboxylates and tri- or tetra-topic phenols gave the corresponding ester-linked COFs. They crystallize as 2D structures in kgm (COF-119) and hcb (COF-120, 121, 122) topologies with surface areas of up to 2,092
palladium/chiral norbornene cooperative catalysis. The obtained C–N axialchirality originates from the preformed transient C–C axialchirality with high fidelity. A variety of C–N axiallychiral phenanthridinones are obtained in excellent enantioselectivities (44 examples, up to >99% ee). This method can be applied for the construction of two stereogenic axes via double atroposelective C–H arylation
