Eighteen trifluoroacetyl derivatives of amino acids and of amino acid analogs were prepared and tested for growth-inhibitory activity using a Lactobacillus casei system as a prescreen for antitumor activity. Of the compounds tested, the trifluoroacetyl derivatives of o-, m-, and p-fluorophenylalanine and of beta-3-thienylalanine showed modest activity; trifluoroacetyl derivatives of phenylalanine and of
制备了十八种氨基酸和氨基酸类似物的三氟乙酰基衍生物,并使用干酪乳杆菌系统作为抗肿瘤活性的预筛测试了其生长抑制活性。在所测试的化合物中,邻,间和对氟苯基丙氨酸和β-3-噻吩丙氨酸的三氟乙酰基衍生物显示出适度的活性。苯丙氨酸和β-2-噻吩丙氨酸的三氟乙酰基衍生物显示边缘活性。活性三氟乙酰基化合物表现出的活性与先前报道的大多数活性氯乙酰基衍生物所指出的活性相同,这是通过将它们与氯乙酰基-间-氟苯丙氨酸的活性进行比较来判断的。当这些抑制剂的代表用相应的天然代谢物挑战时,没有发现抑制作用的逆转,
