IONIZABLE LIPIDS AND LIPID NANOPARTICLE COMPOSITIONS FOR THE DELIVERY OF NUCLEIC ACIDS
摘要:
Novel ionizable lipids are provided. Also provided are novel lipid nanoparticle compositions for the delivery of nucleic acid material to cells in vitro and in vivo with different and improved pharmacokinetic profiles as compared to what is typically observed in the art. Also provided are methods for using the compositions in research and as therapeutics.
An efficient method, tandem [3 + 2] cycloaddition–decarboxylation of α-keto acid and isocyanide promoted by copper salt, has been developed. Under oxidant-free conditions, a series monosubstituted oxazoles have been constructed. Different from the traditional application of α-oxo acids as acyl surrogates, the elegant approach herein ingeniously avoids consuming excess oxidants.

The present invention relates to an organometallic complex, to the preparation of said material, to the use of said material and to a light emitting device which transform electric energy into light. The present invention is further related to provide phosphorescent complexes which contribute to extend the life time in operation of said OLEDs and especially when they are involved in the EL. The objectives of this invention are accomplished by iridium complex comprising 7-membered fused ring ligands which are tris-homoleptic or bis-homoleptic with an ancillary ligand.
