A series of 2-(2-nitrophenyl)benzothiazole 7, 2-(2-nitrophenyl)benzoxazole 10 and 2-(2-nitrophenyl)benzimidazole 13 derivatives have been synthesised and assessed as indicators of nitroreductase activity across a range of clinically important Gram negative and Gram positive bacteria. The majority of Gram negative bacteria produced strongly fluorescent colonies with substrates 7 and 10 whereas fluorescence
一系列的2-(2-硝基苯基)苯并噻唑7苯并恶唑,2-(2-硝基苯基)10和2-(2-硝基苯基)苯并咪唑13衍生物已被合成,并在一系列临床上重要的革兰氏评定为硝基还原酶活性的指标阴性和革兰氏阳性细菌。大多数革兰氏阴性细菌产生带有底物7和10的强荧光菌落,而革兰氏阳性细菌中的荧光产生则较少。的升-丙氨酸16和19和β丙氨酸21和23的衍生物已经从2-(2-氨基苯基)苯并噻唑制备14和2-(2-氨基苯基)苯并恶唑17。已经评估了这四种化合物作为氨基肽酶活性的指标。这些底物通常抑制革兰氏阳性细菌的生长,但是在测试的大多数革兰氏阴性细菌中产生了荧光菌落。
