The synthesis of α-aminophosphonate analogues of tyrosine and tryptophan, e.g. 4 and 5 respectively, and their incorporation into proline-containing dipeptides is reported; of the sequences synthesised, the dipeptide Z-Pro-TrpP(OPh)2 is the only derivative that functions as an irreversible inactivator of the serine proteinase chymotrypsin, in contrast, the tyrosine analogue 4 behaves as a competitive reversible inhibitor of the enzyme and the tryptophan analogue 5 behaves as a slow-binding inhibitor.
报告了酪氨酸和色氨酸的 α-氨基膦酸盐类似物(如 4 和 5)的合成及其与含脯氨酸二肽的结合;在合成的序列中,二肽 Z-Pro-TrpP(OPh)2 是唯一的衍生物。在合成的序列中,Z-Pro-TrpP(OPh)2 是唯一一种可作为丝氨酸蛋白酶糜蛋白酶不可逆灭活剂的衍生物,相反,酪氨酸类似物 4 是该酶的竞争性可逆抑制剂,而色氨酸类似物 5 则是一种慢结合抑制剂。
