摘要:
Disclosed herein are heteromeric molecules comprising two or more different pathogen associated molecular patterns (PAMPs), wherein the two or more PAMPs are linked together with discrete, linear inter-PAMP spacing. Also disclosed are immunogenic compositions comprising the heteromeric molecules and related methods of stimulating an immune response in vivo in a subject or ex vivo comprising administering the immunogenic composition to cells. Also disclosed is a method of synthesizing an immunostimulant comprising: identifying 2 or more different PAMPS, covalently linking the 2 or more different PAMPS together, varying spacing between the 2 or more different PAMPs, and testing the effect of spacing between the 2 or more different PAMPS to identify an optimal spacing that results in immune stimulation.

Disclosed are multi-arm polyethylene glycol derivatives having structure of formula I or formula VI. Compared with straight chain polyethylene glycol, multi-arm polyethylene glycol has a plurality of terminal groups, thus has a plurality of introducing points of functional groups and can support a plurality of reactive terminal groups, thereby enabling multi-arm polyethylene glycol to have more flexibility and wider range of application.
摘要:
Provided is a multi-arm polyethylene glycol-azido derivative of general formula I , wherein R is a central molecule,which is selected from a polyhydroxy structure, a polyamino structure or a polycarboxyl structure; n is the number of branches or arms, n 3; PEG is the same or different —(CH2CH2O)m—, the average value of m being an integer from 3 to 250; X is a linking group of a azido end group; k is the number of the branches having the azido end group; F is selected from the group consisting of amino, carboxyl, sulfhydryl, ester group, maleic imide group and acrylic group; and Y is a linking group of an end group F.
摘要:
The present invention relates to a composition containing a particulate solid, an organic or aqueous medium and a dispersant that may be a reaction product of an organic di or polyepoxide with a primary amine, aminoalcohol, amino acid, hydroxyacid or alcohol containing a fused or non-fused aromatic imide group. The invention further provides compositions for coatings, inks, toners, plastic materials (such as thermoplastics), plasticisers, plastisols, crude grinding and flush.
摘要:
The invention provides a water-soluble polymer comprising (i) an imide group comprising a linking nitrogen atom, a first carbonyl group covalently attached to the linking nitrogen atom, and a second carbonyl group covalently attached to the linking nitrogen atom; (ii) a first water-soluble polymer segment covalently attached, either directly or through one or more atoms, to the first carbonyl group of the imide group and (iii) a second water-soluble polymer segment covalently attached, either directly or through one or more atoms, to the second carbonyl group of the imide group. The invention also provides, among other things, methods for preparing polymers, conjugates, pharmaceutical compositions and the like.
