    • Homocysteine thiolactone derivatives in which the nitrogen is acylated with groups containing acidic functionalities have been synthesized. These include the succinyl, the carboxymethylglutaryl, the 3-phosphonopropionyl and the 3-sulfopropionyl derivatives. These thiolactones can be used to introduce a thiol functionality into proteins such as the outer membrane protein complex of Neisseria meninioitidis (OMPC) allowing conjugation with electrophilic ligands. This chemistry is similar to known N-acetyl-homocysteine thiolactone chemistry, but the pK.sub.a values are such that at pH 7, concomitant negative charge is introduced into the conjugate. Such negative charge neutralizes excess positive charge introduced when arginine- and lysine-rich peptides are bonded as ligands. In the case of OMPC, introduction of positive charge commonly effects irreversible precipitation of the conjugate. Conjugates prepared with the anionic thiolactones have improved solubility.
    • 已经合成了其中氮与含有酸性官能团的基团进行酰化的同型半胱氨酸硫内酯衍生物。 这些包括琥珀酰基,羧甲基葡萄糖基,3-膦酰基丙酰基和3-磺基丙酰基衍生物。 可以使用这些硫内酯将硫醇官能团引入蛋白质,例如允许与亲电子配体缀合的奈瑟氏球菌(OMPC)的外膜蛋白复合物。 该化学类似于已知的N-乙酰基 - 同型半胱氨酸硫内酯化学,但pKa值使得在pH7时,伴随的负电荷被引入缀合物中。 当富含精氨酸和富含赖氨酸的肽作为配体键合时,这种负电荷中和了引入的过量正电荷。 在OMPC的情况下,引入正电荷通常会影响缀合物的不可逆沉淀。 用阴离子硫醇内酯制备的缀合物具有改善的溶解性。
