Chemical linkage reagents, methods of making and method of using the same are provided. Chemical linkage reagents according to at least some of the embodiments of the present disclosure may be incorporated into or operatively-linked with affinity molecules for attachment to silicon oxide surfaces to, for example, measure interactions between an affinity molecule and its targeting biomolecules.

Here we present a new formulation of the recently introduced OxymaPure additive for peptide bond formation, in which the N-hydroxylamine group is replaced by a potassium salt. The complete suppression of its acidity converts KOxyma into the most suitable coupling choice when peptides are assembled on highly acid-labile solid-supports. The cou
'Click' glycosylation of cysteine-containing peptides were carried out in good yield by Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC). For that peptides were functionalized though direct propargylation of the cysteine residue allowing their use in CuAAC with suitable free or protected azido sugars of gluco, manno and galacto configuration. Among these free and protected glycopeptides a series of 'glycoRGD' peptides were obtained and submitted to in vitro platelet aggregation tests, showing that the pseudoglycosylation of the adhesion sequence lowers the IC50 value and thus could improve the in vivo pharmacokinetic properties.

Particles, including nanoparticles and microparticles, and pharmaceutical formulations thereof, containing conjugates of an active agent such as a therapeutic, prophylactic, or diagnostic agent attached to a targeting moiety via a linker have been designed which can provide improved temporospatial delivery of the active agent and/or improved biodistribution. Methods of making the conjugates, the particles, and the formulations thereof are provided. Methods of administering the formulations to a subject in need thereof are provided, for example, to treat or prevent cancer or infectious diseases.
