Carbohydrate
derivatisation and glycocluster formation are both known to enhance avidity for lectin binding. Using a plant toxin and human adhesion/growth-regulatory lectins (inter- and intrafamily comparisons) the effect of their combination is examined. In detail, aromatic substituents were introduced at the 2-N or 3′-positions of N-acetyllactosamine and the products conjugated to two types of calix[n]arenes (n = 4, 6) viathiourea-linker chemistry.
众所周知,
碳水化合物衍生化和糖团的形成都会提高凝集素结合的热敏性。本研究利用一种植物毒素和人类粘附/生长调节凝集素(族间和族内比较),考察了它们结合的效果。具体而言,在 N-乙酰半
