We report the results of a multidisciplinary research effort where the methods of computational photochemistry and retrosynthetic analysis/synthesis have contributed to the preparation of a novel N-alkylated indanylidene-pyrroline Schiff base featuring an exocyclic double bond and a permanent zwitterionic head. We show that, due to its large dipole moment and efficient photoisomerization, such ...
The ability of small particles to associate with DNA and to transport it to desired targets without being subjected to interferences can make them efficient vehicles for gene delivery. Keeping these requirements in mind, zwitterionic latex particles with two different functional tethers were chosen for studying their interaction with DNA as vehicle complexes. From adsorption and electrokinetic ...
Step by step: The sequential coordination of calcium ions (yellow) to four lipid carbonyl oxygen atoms in neutral zwitterionic phospholipid bilayers has been studied by molecular dynamics simulations.
A highly isotactic stereoblock PLA has been obtained using the achiral heteroscorpionate zwitterionic zinc complexes as catalysts, for the first time, via a chain-end control mechanism.
The zwitterionic cyclopentadienyl-bis(2-oxazolinyl)borate diamidozirconium(IV) complex is a precatalyst for the cyclization of aminoalkenes to five- and six-membered rings under mild conditions.
First demonstration of heat and pH-responsive hydrogel of SDS and a zwitterionic amphiphile, sodium N-(n-dodecyl-2-aminoethanoyl)-L-valinate with very low minimum gelation concentration.
A molecular thermodynamic theory is developed for polyampholytes from the coarse-grained charged hard-sphere chain model. The phase behavior of polyampholytes with variations in sequence and chain length is satisfactorily predicted by the theory, consistent with simulation results and experimental observations. At a fixed chain length, the phase envelope expands as the sequence of charge distri...
