synthesized novel irreversible serine protease inhibitors containing aliphatic sulfonyl fluorides as an electrophilic trap. These substituted taurine sulfonyl fluorides derived from taurine or protected amino acids were conveniently synthesized from β-aminoethanesulfonyl chlorides using KF/18-crown-6 or from β-aminoethanesulfonates using DAST. Their potency of irreversible inhibition of serine proteases
我们已经设计和合成了新型不可逆的丝氨酸蛋白酶抑制剂,其中含有脂肪族磺酰氟作为亲电子阱。这些衍生自牛磺酸或受保护的氨基酸的取代的牛磺酸磺酰氟可方便地使用KF / 18-crown-6由β-氨基乙烷磺酰氯合成或由DAST由β-氨基乙烷磺酸酯合成。在使用胰凝乳蛋白酶的不同酶法中描述了其不可逆抑制丝氨酸蛋白酶的能力,导致结合亲和力高达22μM。
