5,5'-二叔丁基-3-(羧甲基)联苯冠醚和几种带有侧链羧酸基团的套索状醚的合成,以及p K a的测定描述了这些冠醚羧酸的值。另外,已经研究了这些冠醚与尿素的络合。大环联苯冠醚(≥29个环原子)和套索状醚(≥27个环原子)都将尿素溶解在氯仿中。套环醚使尿素络合的数据表明,为了有助于尿素络合,重要的是使羧酸基团靠近大环。当套索状醚的羧酸基团位于适当的位置时,尿素被这些大环配体的21–27%络合,联苯冠醚醚羧酸也是如此。这些结果表明,羧酸侧基可以帮助中性分子的络合。

photosensitizing ability to activate the S−H bond of cysteine. The slightly modified QCAT enables the effective photocatalytic cysteine‐specific conjugation of biologically relevant groups. The superior reactivity and cysteineselectivity of this methodology was further corroborated by traceless bioconjugation with a series of complex peptides and proteins under biocompatible conditions.

Bis(2-haloacetamido)- compounds for use as linkers to chemically cross-linking multiple thiol groups, and particularly, although not exclusively, the thiol groups of cysteine amino acids in peptide chains are described, along with their use as linking agents and resultant products which comprise antibodies, half-antibodies and antibody fragments having thiol groups bonded to said linkers (e.g. antibody- protein conjugates and antibody-drug conjugates), and methods of making said conjugates and products.
