salts 27a-d have been synthesized and tested as chromogenic substrates for beta-alanyl aminopeptidase, which is present in Pseudomonas aeruginosa, the most common respiratory pathogen in patients with cystic fibrosis. The biological results show that 7-N-(beta-alanyl)amino-1-pentylphenoxazin-3-one trifluoroacetate salt 27a is a chromogenic substrate for this bacterium, with a low degree of diffusion
已合成新型7-N-(β-丙氨酰基)氨基苯恶嗪-3-酮盐27a-d并作为β-丙氨酰氨基肽酶的生色底物进行了测试,该酶存在于铜绿假单胞菌中,铜绿假单胞菌是囊性纤维化患者中最常见的呼吸道病原体。生物学结果表明,7-N-(β-丙氨酰基)氨基-1-戊基苯恶嗪-3-一三氟乙酸盐27a是该细菌的发色底物,在营养培养基中的扩散程度低,可用于细菌培养和明亮的培养。红色,使其很容易与琼脂背景区分开。
