synthesized as potential inhibitors of L-asparagine synthetase and subjected to screening as antitumor agents. Target amino acids were obtained by condensation of a blocked reactive sulfonyl chloride with the appropriate amine or hydrazide, followed by deblocking with hydrogen--palladium or liquid hydrogen fluoride--anisole. Neither the target compounds nor their protected precursors inhibited the enzyme
合成了一系列与谷氨酰胺结构相关的化合物4-(取代的氨基磺酰基)-和4-(取代的肼磺酰基)-2-氨基丁酸,它们是L-天冬酰胺合成酶的潜在抑制剂,并经过筛选作为抗肿瘤剂。通过将封端的反应性磺酰氯与适当的胺或酰肼缩合,然后用氢-钯或液态氟化氢-茴香醚解封来获得目标氨基酸。目标化合物及其受保护的前体都不能抑制L5178Y / AR的酶或延长P-388淋巴细胞白血病小鼠的寿命。然而,DL-4,4'-二硫代双[2-(苄氧基羰基氨基)丁酸],一种合成目标氨基酸的中间体,在10 mM时对L-天冬酰胺合成酶有90%的抑制作用。
