Synthesis of 12-hetaryl-9,9-dimethyl-7,8,9,10-tetrahydrobenzo[a]acridin-11(12H)-ones
摘要:
Three-component condensation of naphthalen-2-amine with 5-arylfuran(thiophene, N-methylpyrrole)-2-carbaldehyde and 5,5-dimethylcyclohexane-1,3-dione, as well as condensation of N-[(5-arylfuran(thiophen)-2-ylmethylidene]naphthalen-2-amine with 5,5-dimethylcyclohexane-1,3-dione gave the corresponding 12-[5-arylfuran(thiophen, N-methylpyrrol)-2-yl]-7,8,9,10-tetradrobenzo[a]acridin-11(12H)-ones.
An easy operable method of detecting phosphatase which comprises a step for the production of a dye to obtain an azo dye by the reaction of phosphatase in a tissue or cell or on chromosome with a 2'-naphthol AS phosphate, e.g. 3-hydroxy- N-2-biphenyl-2-naphthalenecarboxamide phosphate ester, followed by the reaction between the 2'-naphthol AS phosphate with a diazonium salt; an excitation step for the irradiation of excited light to the azo dye; and a detection step for the detection of fluorescence which is emitted upon irradiation of the excited light. The fluorescence is intense and lasts for a long time.
一种易于操作的检测磷酸酶的方法,它包括一个生产染料的步骤,通过组织或细胞或 染色体上的磷酸酶与 2'-萘酚 AS 磷酸酯(如 3-羟基-N-2-联苯-2-萘甲酰胺磷酸酯)反 应,得到偶氮染料;一个激发步骤,用于激发组织或细胞或染色体上的磷酸酶。3-hydroxy- N-2-biphenyl-2-naphthalenecarboxamide phosphate ester,然后 2'-naphthol AS phosphate 与重氮盐反应;激发步骤,将激发光照射到偶氮染料上;检测步骤,检测激发光照射后发出的荧光。荧光强度高,持续时间长。
