Polymeric dispersants containing one or two quaternary amine anchoring groups with improved chemical and thermal stability

The present invention relates to a dispersant having a tertiary or quaternary amine anchoring group and a solubilizing polymer selected from C.sub.8-50 fatty acid; a C.sub.8-50 ak(en)yl substituted succinic acid, anhydride or partial ester; a dimer or trimer fatty acid; and/or polymers from repeating units of polyesters, polyethers, polyacrylate, polyamides, polyurethanes or mixtures of said repeating units in a random or blocky copolymer. The dispersants are an improvement in that the alkylene connecting group between the tertiary or quaternized amine and the solubilizing polymer lacks abstractable hydrogen atoms at the geminal carbon atom from the nitrogen of the tertiary or quaternized amine over the prior art. The dispersants are useful as dispersants with improved thermal stability and low amounts yellow color after aging at elevated temperatures.

FLOW CELLS

An example of a kit includes a flow cell, a primer fluid, and a cleaving fluid. The flow cell includes at least one surface functionalized with a polymeric hydrogel including azide functional groups or amine functional groups. The primer fluid includes a plurality of alkyne-containing primers, each alkyne-containing primer having an amino cleavable group attaching a primer sequence of the alkyne-containing primer to an alkyne-containing moiety of the alkyne-containing primer. The cleaving fluid includes a substance that is reactive with the amino cleavable group.

POLY(AMINE-CO-ESTER) POLYMERS WITH MODIFIED END GROUPS AND ENHANCED PULMONARY DELIVERY
20230233693 · 2023-07-27 ·

Poly(amine-co-ester) polymers, methods of forming active agent-load polyplexes and particles therefrom, and methods of using them for delivery of nucleic acid agents with optimal uptake have been developed. Examples demonstrate critical molecular weights in combination with exposed carboxylic and/or hydroxyl groups, and methods of making. Typically, the compositions are less toxic, more efficient at drug delivery, or a combination thereof compared to a control other transfection reagents. In some embodiments, the compositions are suitable for in vivo delivery, and can be administered systemically to a subject to treat a disease or condition. For poly(amine-co-ester) polymers with specific amine or hydroxyl group containing end-groups in admixture with PEGylated poly(amine-co-ester) polymers, in vivo delivery to the lung by inhalation has been shown.
