New suppressed fluorescent origin Characteristic chemical compound

摘要

(57) Abstract The chemical compound general formula (i) Conversion 1 [In formula, R¹, R², R³, R⁴ and R^{5 the} hydrogen atom and pigment origin Characteristic (chromogenic) to be the substituent, as for X, hydroxyl; OR⁶ (as for R⁶, from group which consists of C₁ - C₄ alkyls it is chosen,); Or (as for Me ⁺, organicity or cation which is induced from inorganic base it is,) it is O-Me ⁺]. These chemical compounds do not show significant fluorescence, but it can be cleft the enzyme phosphatidyl which is collimating mark of bacterial activity - by inositol unique phospholipase C; The effective test manner regarding the various pathogenic bacteria where the umbelliferryl part which it occurs from that kind of cleavage is powerful fluorescent source, therefore, like Listeria, Staphylococcus and Clostridium genus is offered. Synthetic manner is disclosed. The genus whose general formula (i) chemical compound is desirable 4 - mechiruunberihuerirumio - the inositol - 1 - the phosphate and the organicity or is that salt of the inorganic base.
