The described New video diagnosis and treatment preparation method of reagent thereof based on tryptophan and its derivative specifically includes following steps:
Step 1:Radioactive label
By tryptophan and its borate precursor and Cu (Pyr) of derivative4(OTf)2It is dissolved in DMF;Mixture is in rubber
Barrier film and aluminium crimping cap closure in the reaction tube of Feng Youyi atmospheric air while carry out;By Fluorine source18F-TBAF(18The fourths of F- tetra-
Base ammonium fluoride) MeCN solution be added dropwise by insulin syringe, reaction under the conditions of 110 DEG C stir 20 minutes.
Step 2:Deprotection and post-processing step A
After radioactive label, H is added in rapid product one step up2SO4, and reacted 10 minutes at 140 DEG C, reaction knot
It is cooled to room temperature after beam, reaction solution is neutralized with NaOAc solution, and with aluminum oxide solid-phase extraction column separation and Extraction;
Or, step 2:Deprotection and post-processing step B
After radioactive label, TFA is added in rapid product one step up, and reacted 5 minutes under the conditions of 130 DEG C, reaction
Liquid is heated by batch (-type) and argon gas stream is concentrated.Residue is configured to suspension with KOH, and 5 points are reacted under the conditions of 160 DEG C
Clock;Reaction is neutralized after terminating with 50%AcOH solution, and with aluminum oxide solid-phase extraction column separation and Extraction.
Further, the radioactive source is Fluorine source18F-TBAF。
It is solid by aluminum oxide after object is by radiolabeled general step and deprotection and post-processing step A
Crude product is obtained after phase extraction column, crude product is purified by HPLC and following condition.
The present invention also illustrates tryptophan derivative, and (including the tryptophans that methylate of N- and alpha-methylated tryptophan spread out
It is biological) halogenated precursors synthetic method, synthetic route is:
Concretely comprise the following steps:Under condition of nitrogen gas, Pd (dppf) Cl is loaded in history Ranque tube2, KOAc and B2pin2, and add
Enter the tryptophan methyl ester under anhydrous DMSO and B DEG C of protection, 12h stirred under the conditions of 80 DEG C, reaction is cooled to room temperature after terminating,
Target substrates must be corresponded to by crossing post separation by ethyl acetate/petroleum ether.
Synthetic product includes:
Synthetic reaction has:
Experiment it is initial, we want to confirm whether induction prothetic group (being easily converted to the functional group of halo, such as boron) can be with
It is introduced in each position of tryptophan.As shown in scheme 1A, using the tryptophan derivative of iodo or bromo as substrate, lead to
Miyaura boron glycosylation reactions are crossed, borate group Bpin can successfully be incorporated into 4,5,6 and No. 7 positions of indole ring.In order to
The presence reduction flag rate of N-H groups acid on indoles is prevented, we are protected to nitrogen-atoms with BoC groups.Except
Borate precursor can be fluorinated, and iodonium ylides can also equally realize that electron rich aromatic ring is Radiofluorinated (such as scheme 1B institutes
Show).The synthetic work of borate above and iodonium ylides is to realize that the Radiofluorinated of tryptophan provides the foundation.
The synthesis of the radiolabeled tryptophan derivative of scheme 1
Then, our focuses of work are mainly focused on has been carried out together to the Bpin of 4,5, the 6 and No. 7 positions tryptophans replaced
Position element mark.With anhydrous18F- tetrabutyl ammonium fluorides react progress 20 minutes under 110 degrees Celsius, and then a step as Fluorine source
Deprotection, we respectively obtain 4,5,6,7- with 2.8-8% separation yield (without correction for attenuation)18The tryptophan of F marks.By
Sensitive to alkali in DDTC, tetrabutyl ammonium hydrogen carbonate is largely residued in as phase transfer catalyst18In F- tetrabutyl ammonium fluorides, because
This uses larger amount of18F- tetrabutyl ammonium fluorides on the contrary can reduction flag rate.It may be increased using other weakly alkaline Fluorine sources
Mark rate.Because mark reaction is generally to acid-sensitive, in order to improve reaction yield, we are protected to acid indoles-NH
Shield.However, we are when synthesizing 7-Bpin tryptophan, the BoC protection groups of indoles N atoms are dissociated in building-up process, are pushed away
Survey may due to Bpin groups and BoC protection groups space it is crowded caused by.But we are still isolated with considerable yield18F-
The fluoro- tryptophans of 6- (6.4% separation yield, without correction for attenuation), this shows that the protection to indoles-NH is not necessary.
In addition to being easy to synthesis, we do not use optically pure initiation material in the synthesis of all substrates, because we are main
New 18F-PET reagent of the research and utilization radioactive halogenation reaction synthesis based on tryptophan and its derivative.If these reagents
It is synthesized and applies in imaging technique in the future, we can be respectively studied D, L-configuration.
The tryptophan derivative of scheme 2 it is Radiofluorinated
We expand substrate spectrum, have attempted the tryptophan derivative of other substituted bases.As shown in Scheme 3,1- methyl
Replace and can be obtained in indole ring C-5 and the C-6 tryptophan derivative for there are Bpin prothetic groups with synthesizing in high yield, synthesize these examinations
After agent, we select that experiment is marked exemplified by 5-Bpin-1- methyl tryptophans, with high radiochemical purity and 7.9% receipts
Rate is obtained18The fluoro- 1- methyl tryptophans of 5- of F marks.
Synthesis (B) other positions 1- methyl tryptophans precursor (C) 5- of scheme 3 (A) 5-Bpin-1- methyl tryptophans
The labelling experiment of Bpin-1- methyl tryptophans
We use Alpha-Methyl tryptophan as the 3rd class tryptophan reagent, in fact,11C- Alpha-Methyls-L-Trp
(AMT) it is a kind of tryptophan homologue, possesses great potential application in cancer research.However, due to11C is shorter partly to decline
Phase, so as to limit its extensive use in clinical test, it is impossible to realize large-scale production and its commercialization.As shown in Scheme 4,
We are obtained with high radiochemical purity and 7.9% yield18F-5- fluoro-alphas-methyl-L-tryptophan.5-Bpin-AMT precursors can
To be synthesized by two kinds of paths, method synthesis step is relatively fewer shown in scheme 4, but it is Radiofluorinated after deprotection condition
It is harsh.Another method synthesis step is more (as shown in scheme 5), be advantageous in that it is Radiofluorinated after deprotection process condition
Gently.In addition, although we are only tested to 5-Bpin- Alpha-Methyls-L-Trp, the fluorination of other positions can be adopted
With same response strategy.
