PHYSICO-CHEMICAL PROPERTIES OF Nd(III) AND Er(III) COMPLEXES WITH SOME BIOLOGICAL BUFFER LIGANDS
摘要:
The new Nd(III) and Er(III) complexes with the zwitterionic buffer ligands N-tris[hydroxymethyl]methyl-3-aminopropane-sulfonic acid sodium salt (NaTAPS) and 3-[N,N-bis(2-hydroxyethyl)amino]-2-hydroxypropanesulfonic acid sodium salt (NaDIPSO) have been prepared and characterized by IR, DTA, TG, mass, elemental analyses and electrical conductivity measurements. The Nd(III) complexes may be formulated as [Nd(DIPSO)(2)(H2O)(n)]NO3 . mH(2)O, where n = 1 and m = 1 for NaDIPSO as ligand while n = 2 and m = 0 for NaTAPS as ligand, [Nd(TAPS)(2)(H2O)(n)]NO3. The Er(III) complexes may be described as [Er(DIPSO)(2)(H2O)n]Cl . mH(2)O, where n = m = 2 for NaDIPSO as ligand while n = 2 and m = 0 for NaTAPS as ligand. Thermogravemetric studies show that the Er(III) complexes are thermally more stable than the Nd(III) complexes. The electrical conductivity of DMF solutions of these complexes indicate 1:1 electrolytic behavior.

The invention relates generally to disulfide drug conjugates wherein a linker comprising a sulfur-bearing carbon atom substituted with at least one hydrocarbyl or substituted hydrocarbyl is conjugated by a disulfide bond to a cysteine sulfur atom of a targeting carrier, and wherein the linker is further conjugated to a drug moiety. The invention further relates to activated linker-drug conjugates suitable for conjugation to a targeting carrier by a disulfide bond. The invention further relates to methods for preparing hindered disulfide drug conjugates.
