A process for synthesizing phosphoramidites by immobilizing a phosphitylating agent on an activated resin to create a loaded resin and then bringing the loaded resin into contact with a suitable substrate. The phosphoramidites are synthesized within minutes from applying the starting materials. Thus, the process makes it possible to create specific phosphoramidites on-demand as they are needed in further applications. The substrates to be applied are mostly nucleosides, thus to create nucleoside phosphoramidites for subsequent oligonucleotide synthesis.

This document relates to functionalized (e.g., mono- or bi-functional) polymers (e.g., polyethylene glycol and related polymers) as well as methods and materials for making and using such functionalized polymers.

A new process to synthesis of compound OBI-3424 R-form and S-form products is provided. The “R-form” compound OBI-3423 was first synthesized with 48% overall yield from compound OBI-3424-5 by installation of the labile phosphate motif at later stage. The stereo chemistry is established by 5 steps chemo-enzyme combination synthesis to afford 99% optical purity. After then, the “S-form” compound OBI-3424 is prepared with improving overall yield of 54% from compound OBI-3424-5. The stereo chemistry is established by 4 steps combination of chemo-enzyme synthesis with excellent optical purity of 99%.

Provided herein are novel materials and methods for site-specific incorporation of phosphotyrosines into proteins. The novel methods of the invention encompass the use of a novel aminoacyl tRNA synthetase capable of charging compatible tRNAs with a phosphotyrosine precursor. The phosphotyrosine precursor is then incorporated, site-specifically, into a protein at sites where phosphotyrosine residues are desired. The phosphotyrosine precursors are subsequently treated to convert them into phosphotyrosine residues, yielding proteins with phosphotyrosines at selected sites. The scope of the invention encompasses novel aminoacyl tRNA synthetases, novel phosphotyrosine precursors, and methods of using these materials to create site-specific phosphorylated tyrosine residues in a protein.

Provided herein are lipid compounds that can be used in combination with other lipid components, such as neutral lipids, cholesterol and polymer conjugated lipids, to form lipid nanoparticles for delivery of therapeutic agents (e.g., nucleic acid molecules) for therapeutic or prophylactic purposes, including vaccination. Also provided herein are lipid nanoparticle compositions comprising said lipid compounds.
