CCK2R Ligand-Linker Conjugate 1 is a hydrophilic peptide linker that conjugates to the cytotoxic antimicrotubule agents Desacetyl Vinblastine Hydrazide (DAVBH) and Tubulysin B Hydrazide (TubBH) as ligand-linker conjugates[1].
Mal-amido-(CH2COOH)2, also known as compound 7a, is an intermediate compound that contains maleimidoethyl for use in hydrophilic ADC linker synthesis[1].
Biotin-PEG7-amine is a PEG derivative containing a biotin group and a terminal primary amine group. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound.
