Meso tetra (4-N, N, n-trimethylaminophenyl) porphyrin (ttmapp) /meso tetra - [4- (BOC threonine) aminophenyl] porphyrin (TAPP thr BOC) supplied by Qiyue

meso- Four (4-N,N,N- Trimethylaminophenyl ) porphyrin (TTMAPP) Introduction to

 

4-N,N- Dimethyl aminobenzaldehyde and pyrrole are heated and refluxed in propionic acid 24 Cool to room temperature after hours , Filter , The solid obtained by washing with methanol , That is, get dark blue meso- Four (4-N,N- Dimethylphenylamino ) porphyrin (TDMAPP).meso- Four (4-N,N,N- Trimethylaminophenyl ) porphyrin (TTMAPP) from TDMAPP With methyl p-toluenesulfonate in DMF Medium reflux , The crude product is washed with acetone 3 Time , Dry in the air to get pure product .

meso- Four -[4-(Boc- Threonine ) Aminophenyl ] porphyrin (TAPP-Thr-Boc)

Amino acid porphyrins are used in this paper :meso- Four -[4-(Boc- Threonine ) Aminophenyl ] porphyrin (TAPP-Thr-Boc) For small biological molecules L- Molecular recognition of tryptophan .TAPP-Thr-Boc It is a symmetrical cationic amino acid porphyrin compound , Its structure is shown in the figure 1 Shown , In biological systems ,L- Tryptophan is -- A common luminescent group , When it interacts with many metal ions and organic small molecule compounds, its fluorescence will be quenched . therefore , The study of quenching effect will provide the binding sites and conformational changes of proteins ,

This paper studies TAPP-Thr-Boc Determination L- The optimum conditions of tryptophan and its application in practical samples . be based on . The above results , We can draw :(1) Secondary amino acid porphyrin :meso- Four -[4-(Boc- Threonine ) Aminophenyl ] Porphyrins are very sensitive to small biological molecules L- Molecular recognition of tryptophan , And as a probe L- Tryptophan . In anionic surfactants AOT Under the condition of existence ,TAPP-Thr-Boc Can quench L- Fluorescence of tryptophan , A new kind of L- Determination of tryptophan .(2) Compared with other fluorescent spectral probes , Amino acid porphyrin (TAPP-Thr-Boc) As a fluorescence probe for quantitative determination L- The results of tryptophan were satisfactory. This new system has been used in piglet feed L- Tryptophan was determined with satisfactory results .
