Synthesis of TP10-SS-Flu-ITAM (5). The TP10-carrier was first prepared on the resin with the Fmoc-Lys(Boc-Cys(Trt))-OH (20) building block incorporated into the sequence (seventh residue from the N-terminus). During cleavage and deprotection the cysteine was activated, yielding TP10-Cys(pNpys) (22). This carrier was conjugated to cargo Flu-ITAM (30) to yield the construct 5.

Palladium diacetate
CAS number: 3375-31-3
Palladium acetate is a chemical compound of palladium. It is used as a catalyst for many organic reactions and as a precursor to other palladium(II) compounds. It has now been found that palladium diacetate can be prepared in crystalline form free of undesired contaminants such as palladium hydroxy acetate by reaction of specially prepared hydrous palladium oxide (referred to hereinafter as HPO).

epsilon-N-1-(1-deoxylactulosyl)lysine
CAS number: 34326-63-1
Epsilon-N-1-(1-Deoxylactulosyl)-L-lysine is a specific chemical compound formed when lactose reacts with lysine, a type of amino acid, under certain conditions. It is an Amadori product, meaning it's formed through a Maillard reaction where a reducing sugar (like lactose) reacts with a primary amine (lysine). This reaction can occur during food processing or under physiological conditions.
