(2) application study:
By the non-ionic water solubility of the cycloaddition synthesis with different chains number polyethylene glycol (PEG) of nitrine-alkynes Tetraphenyl ethylene (TPE)-functionalization polyethylene glycol (PEG) shiner (P1/6, P2/6 and P3/6), by hydrophobic TPE become Into hydrophilic molecules.These shiners show preferable heat endurance, referring to table 1, the wherein T of P1/6, P2/6 and P3/6dPoint Wei 351.6 DEG C, 342.2 DEG C and 352.1 DEG C.As shown in figs. 4 a-4d, the polymer after these synthesis is water-soluble and amphipathic , show AIE characteristics in THF/ aqueous solvent systems and THF/ hexane solvent systems.In a large amount of aqueous solution, these gather Compound forms micellar copolymerization thing when exceeding critical micelle concentration (CMC).As shown in Fig. 5 A, 5B and 5C, by using these polymerizations During thing coherent condition the luminous property of autofluorescence obtain P1/6, P2/6 and P3/6 CMC be respectively 0.09mM, 0.12mM and 0.20mM, particle diameter respectively may be about 100nm.All results show that the micella of these polymer is by the nonpolar TPE heads in inner side With the hydrophilic PEG chains composition for pointing to aqueous medium.These polymer are then individually dissolved in medium and do not send out in below CMC Light, when concentration is increased to more than CMC, these polymer initially form micella, and TPE moiety aggregations show in hydrophobic interior Stronger fluorescence radiation.Therefore, because restriction (the restriction of intramolecular of Internal Rotations of Molecules Rotation, RIR) impact to micellization, these polymer become to light.
In order to study impacts of the P1/6 to living cells, using CCK8 cytotoxicity analysis are carried out.WST-8([2-(2- methoxy-4-nitropheny)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H-tetrazoliun, Monosodium salt], [2- (2- methoxyl group -4- nitrobenzophenones) -3- (4- nitrobenzophenones) -5- (2,4- double sulfophenyls) -2H- Tetrazole, sodium glutamate] first a ceremonial jade-ladle, used in libation is changed into by intracellular dehydrogenase, it is directly proportional to the quantity of living cells.Such as Fig. 6 institutes Show, the cytotoxicity of P1/6 is in dose dependent after P1/6 is exposed to HepG2 cell 24h.Concentration is 50,75,100,125 μ Cell survival rate corresponding to g/mL is respectively 99.93%, 98.1%, 95.82% and 92.94%, and in concentration 150 μ g/ are reached During mL, cell survival rate still remains above 86%.There is data to suggest that P1/6 has the preferable biology for living cells imaging Compatibility.
Table 1:The molecular weight and thermal property of P1/6, P2/6 and P3/6
As pharmaceutical carrier be used for clinical practice aspect, PEG be bio-compatible and suitable for transmit organic coloring agent It is extremely intracellular.Pure coloring agent TPE cannot be penetrated into intracellular space (non-display data) because of its high hydrophobicity.Due to having The preferably optical characteristics of AIE properties, using the PEG polymer of TPE- functionalization to adherent type HepG2 cell dyeing as life Physical prospecting pin.Amphipathic nature polyalcohol tends to form nanometer polymer in aqueous solution, and it can be promoted thin by endocytosis Born of the same parents absorb.As shown in fig. 7, when HepG2 cells dye 12h by P1/6, can light from cytoplasmic region.With the increasing of P1/6 concentration Plus, fluorescence becomes higher, and the efficiency for showing endocytosis depends on P1/6 dosage in the medium.Although as shown in figure 8, thin The P2/6 and P3/6 of born of the same parents and high concentration carries out cultivating the longer time, but lights compared with P1/6 and want much weaker.This species diversity is returned Because of the ratio between TPE and PEG.
In order to monitor cellular morphology for a long time, manufacturer has done the best the load time improved after dyeing.For example, business is thin Born of the same parents' tracker, CellTrackerTMBlue CMAC (7-Amino-4-Chloromethylcoumarin, 7- amino -4- chloromethyls Cumarin) and blueness CMHC (4-chloromethyl-7-hydroxycoumarin, 4- chloromethyl-umbelliferone) by chlorine Methyl functional group's functionalization.When the probe of tracker enters intracellular, probe can enter with the mercaptan on proteins and peptides Row reaction, but cell can only be illuminated after dyeing about 24 hours according to agreement coloring agent.As shown in figure 9, as first Generation, HepG2 cells living are exposed to P1/6 polymer 24 hours, send high light.Because in the cell large biological molecule PEG can lock Firmly fluorogen, intracellular P1/6 is passed to careful intracellular.Although the increase in hyperplasia generation causes fluorescence to die down, probe is also It is can to follow the trail of to the 5th generation.Therefore, P1/6 can be used as long-term living cells tracker, be potential alternative.Therefore, this is glimmering Photopolymer can be applicable to monitor Intracellular drug release.

(2) application study
Cell membrane is the protective barrier of cell, and the integrality, growth and death for cell is most important.In the urgent need to Shiner in living cells and dying cell to cell membrane imaging.There is provided a kind of new amphipathic with four benzene second in the present embodiment Pyridiniujm (tetraphenylethene-based pyridinium salt, TPE-MEM) based on alkene, with significant Aggregation-induced emission (AIE) characteristic, and for the dyeing of selecting cell film.Fluorescence probe (the TPE- of the shiner of the high yield MEM) it is synthesized by following, including asymmetric McMurry reactions, Suzuki coupled reactions and with doubly charged pyridiniujm And the condensation reaction between hexyloxy tetraphenyl ethylene benzaldehyde (hexyloxytetraphenylethene benzaldehyde). Due to double charge characteristic, TPE-MEM has poor dissolubility in non-polar solven, such as in THF and DCM non-polar solvens In, but it is solvable in polar solvent, it is such as solvable in water, DMF, DMSO and methyl alcohol.
Figure 10 shows ultraviolet (UVs) and luminescence generated by light (PL) spectrum of the TPE-MEM in aqueous solution (40 μM).TPE- The absorption maximum wavelength of MEM falls in 395nm.For convenience biologic applications, using 405nm as excitation wavelength PL measure is carried out. The light of aqueous solution excites induction in 590nm Yellow light-emitting low temperatures, and expression there occurs a large amount of displacements of 185nm, and this is made by extended conjugation With and from the Intramolecular electron transfer (intramolecular of electron donor TPE aglucons to electron acceptor pyridine unit Charge transfer, ICT) cause.
As shown in Figure 11 A and 11B, TPE-MEM shows substantially contrary AIE properties, and this is due to its highly polar property Caused by matter.The DMSO solution of TPE-MEM (25 μM) is luminous weaker, and in the THF of content 99%, it is strong in the luminous changes of 625nm. In view of the molecular structure of TPE-MEM, thus it is speculated that amphipathic TPE-MEM molecules can form micelle in the case of high concentration.Benefit In the property of AIE, the critical micelle concentration (CMC) of TPE-MEM can be measured using the fluorescence intensity of its own.Such as Figure 12 Shown, the concentration of TPE-MEM is molecular melting in below CMC, therefore does not produce fluorescence;In more than 0.01mM, PL intensity urgency Increase severely strong;Correlation curve between PL intensity and stain concentration produces two lines, and the crosspoint of two lines determines that CMC is 0.02mM.As illustrated in figures 13 a and 13b, also demonstrate that in high dye by transmission electron microscope and eletrokinetic potential Particle Size Analyzer The formation of nanometer polymer and CMC value in toner concentration.The effective diameter of aqueous micellar is 77.4nm, with dehydration effectively directly Footpath tapers to 40nm.When TPE-MEM the following is molecular melting in CMC, it is impossible to detect particulate;When in CMC (0.02mM) when more than, it can be observed that particulate.The inflection point determined by PL is identical with CMC value.Additionally, the grain of nanometer polymer Footpath had both been suitable for cell in vitro intake and body-internal-circulation, and bio distribution is suitable for again.
Before cell imaging, using MTT colorimetric methods in the intracellular cytoactives that can determine TPE-MEM of HeLa and Cytotoxicity.Under the conditions of 37 DEG C, dark CO2 incubator inner cells be exposed to variable concentrations (0,2.5 μM, 5 μM, 10 μM, 20 μM) TPE-MEM 6 hours, be then further cultured for 18 hours carrying out cell propagation in the fresh culture medium of incubator.Such as Shown in Figure 14, even if the concentration for as a result showing TPE-MEM in the dark reaches 20 μM of also typically no cytotoxicities.Then as It is contemplated that be used for the dyeing of selective cell membrane to TPE-MEM being estimated.As shown in figures 15 a-d, using CellMaskTM The experiment of combined staining that Deep Red cell membrane coloring agents (C10046) is carried out show the fluorescence observed from TPE-MEM be from In the cell membrane of HeLa cells living, the wherein cell membrane coloring agent is a kind of commercially available cell membrane imaging agent.It is logical Cross and use Laser Scanning Confocal Microscope (CLSM LSM7;Carl Zeiss, Germany) software, determine Figure 15 A and Figure 15 B between Overlap coefficient is 72%.Overlap coefficient is at a relatively high, and this is due to the competition between thin-layer cell membrane structure and two kinds of coloring agents Suppress.Compared with C10046, TPE-MEM shows less internalization effect, and the imaging to cell membrane shows preferably Imaging resolution.More very, by TPE-MEM it will be appreciated also that see cell microvillus.Except complex staining experiment, also enter The Z-type CLSM that gone scans (Z-stack CLSM scanning).
Cell membrane is the organelle that larger negative potential is shown on the interface of film, the phospholipid bilayer master on the organelle To be made up of thin amphipathic phospholipid bilayer.Therefore, it is amphipathic that cell membrane target organism coloring agent generally needs to meet And cation.The hydrophobicity and hydrophily of coordinated balance molecule is to meet the amphipathic of cell membrane, and this is new for designing Cell membrane biological coloring agent is most important.TPE-MEM has a characteristic amphipathic and with positive lotus, therefore can be used as splendid using it Biological stain, for the cell membrane of specific stain living cells.Amphipathic TPE-MEM is spontaneous to be arranged in phospholipid bilayer, To make hydrophobic tail region be to electrostatically attracted in the double-deck interior and hydrophilic head region that the polar liquid with around is isolated The phosphate of negative electrical charge.Such as electrostatic force and Van der Waals interaction force (van der Waals interactions) Dye etc. specific targets are caused.
For cell imaging coloring agent, light resistance is one of most important standard.Some for specific cell dyeing AIE coloring agents are all high-light-fastness.Helical molecular structures and its polymerization forming process can prevent oxygen from diffusing into AIE In particulate, oxygen meeting oxyluciferin into AIE particulates is rolled into a ball and makes its PL light and bleaches.As shown in figure 16, in living cells Similar light resistance result is obtained.According to initial fluorescent intensity standardized fluorescent intensity.As shown in figure 16, total irradiation time 5 Minute (30 scanning), the loss of signal of TPE-MEM is less than 40%.Time from 0s to 325.7s, the loss of signal is bright with imaging Degree is slightly decreased, and this is the diffusion due to coloring agent and the movement of cell.
As shown in figure 16, bubble can be seen in series of scans in CLSM time courses.It is apparent that cell fine hair shrinks And disappear, laser scanning is then based on, cell expansion is simultaneously revealed, it is seen that cytoplasma membrane becomes discontinuous and is seepage.It is this Phenomenon shows that cell death is by the reason for caused by laser scanning, this just excites people's follow-up study strongly.Pi-conjugated Phenthazine (phenothiazinium) the base molecule with positive charge is widely used in active oxygen (ROS) and generates and light in system Therapy.Compared with phenthazine, TPE-MEM also has positive charge in Pi-conjugated systems, and this is possible to that photoinduction ROS can be caused to give birth to Into causing cell death.
In order to confirm above-mentioned it is assumed that carrying out ROS detections using commercial ROS fluorescence probes H2DCFDA.When by already present During ROS oxidation H2DCFDA, can detect in 535nm (λex=488nm) transmitting hyperfluorescence.Surprisingly, it is normally white Room light (LED bulb, 3W) produces enough ROS when being irradiated to TPE-MEM solution.PBS solution containing H2DCFDA, contain The PL spectrum of the PBS solution of TPE-MEM and the PBS solution simultaneously containing H2DCFDA and TPE-MEM are all in identical room What light-illuminating was obtained.PL spectrum (Figure 17 A, the λ of record sample difference irradiation timeex=488nm) and the peak value of 535nm it is strong Correlation curve (Figure 17 B) between degree and irradiation time.In Figure 17 A, when there is H2DCFDA and TPE-MEM simultaneously in solution When, oxidized H2DCFDA occurs and as light irradiation strengthens in the characteristic peak of 535nm.Even if measurement result shows compartment lamp The light irradiation time, PL intensity still persistently strengthened, and just makes fluorescence bleach within ultraviolet light only a few minutes more than 120 minutes (non-display data).Individually H2DCFDA solution and single TPE-MEM solution are by the PL Strength Changes after room light-illuminating Slightly.Observation indicate that actually light is radiated at the ROS produced when TPE-MEM, causes cell damage and death.
However, the pathology of cell death are still without method interpretation.The integrality of cell membrane be most important morphological feature it One, for distinguishing Apoptosis and meronecrosis.During meronecrosis, cell expansion, cell membrane become it is leaky simultaneously Division, final cell exchanges material with surrounding environment.Propidium iodide (propidium iodide, PI) is impermeable by thin After birth, generally exclude outside living cells.When cell membrane is leaky, PI is usually used in the karyon to dead cell and dyes.Cause This, PI is opened for dead cell being recognized in a large amount of cells and in multicolor fluorescence technology as counterstain.In this example In, as shown in figure 18, TPE-MEM is added and is marked to the culture medium with living cells, is then introduced to PI to observe base It is interior.As shown in the A-D in Figure 18, the TPE-MEM (channel come from cell membrane can be only detected before light irradiation I gold-tinted).When irradiating cell about 5 minutes (30scans), then another 5 minutes are irradiated for absorbing PI, such as Figure 18 In E-H shown in, it is observed that the change of cellular morphology and coming from PI in the cytoplasm and nucleus in portion in the cell The ruddiness that (channel II) sends out.It is because PI Intercalations cause to DNA to come from the ruddiness that PI sends out in nucleus PI glows, and intracytoplasmic danger signal is likely to be cell karyorhexis and enters to what is caused in cytoplasm.Do not having In the Control release of TPE-MEM, (I-L in Figure 18) is all not detected by redness after pre-irradiation (non-display data) and irradiation Signal (channel II).All observation results show that cell membrane becomes leaky, show in the case where there are TPE-MEM Carrying out light irradiation can cause meronecrosis.
All results show that TPE-MEM promotes to produce ROS under room light-illuminating.TPE-MEM is except with cell membrane Selective and fabulous light resistance, TPE-MEM can the potential lucotherapy medicine as treating cancer.In order to assess using normal Impact of the lucotherapy of room light-illuminating TPE-MEM to HeLa cancer cell multiplications, as shown in figure 19, by mtt assay, for Room light-illuminating 2 hours and do not irradiate 2 hours two kinds of situations and determine the cell survival of the TPE-MEM containing variable concentrations respectively Rate.By the MTT values for determining and the relation preparation standard between the MTT values that the sample of TPE-MEM and non-illumination is measured is not contained Curve further calculates cell survival rate.
The result of Figure 19 shows that undosed cell is that have survival rate and the cell survival rate from 0 μM -10 μM is about 90%, the sample for not containing TPE-MEM does not show toxicity Jing after room light-illuminating.However, the TPE- of Jing rooms light-illuminating MEM produces ROS, and in the cell survival rate of the TPE-MEM containing 10 μM 47% is down to.In the case of containing TPE-MEM, Jing rooms Between light-illuminating sample and the sample without room light-illuminating between obtain than larger cell survival rate difference.White room Between light-illuminating be gentle, be readily available and cheaply, with reference to the high yield for producing ROS so that lucotherapy non-hazardous, resistance to Light, dark toxicity are low.It is a kind of preferable sensitising agent (being referred to as emulsion) that all of advantage causes TPE-MEM.
Even if it is difficult to identify the mechanism that ROS materials and explanation ROS are produced, but being observed that the generation of ROS.ROS Having shown that can strengthen the propagation of cancer cell, but the ROS levels of excess can cause cancer cell-apoptosis and necrosis.In this example In, cell membrane biological coloring agent (TPE-MEM) produces excessive ROS by room light-illuminating, can in real time visualize original The process of position cancer cellular necrosis.
In a word, the asymmetrical amphipathic tetraphenyl ethylene yl pyridines salt with strong AIE characteristics of synthesis (tetraphenylethene-based pyridinium salt, TPE-MEM) can be used for cell membrane dyeing.Due to cation With it is amphipathic, TPE-MEM cell membrane is had high specific and in living cells have splendid light resistance.Unexpected It is only generation ROS just can effectively to be induced by TPE-MEM under normal room light-illuminating, causes meronecrosis.These are unique Feature allows to the process of Real Time Observation meronecrosis in the original location and the process of lucotherapy.Therefore, ROS and can light is produced The result of gamma therapy causes the shiner of the present embodiment to can be used to prepare the new AIE lucotherapy medicines for the treatment of cancer.

(3) application study
In order to reach dual-use function, synthesize in the present embodiment containing GD- diethylenetriamine pentaacetic acid (Gd- Diethylenetriamine pentaacetic acid, DTPA) chelate TPE derivatives (TPE-2Gd), then to it Carry out the detection of photophysical property.Uv-vis spectra shows the maximum absorption wavelength of TPE-2Gd in 330nm, with parental generation fluorescence The maximum absorption wavelength similar (non-display data) of element-TPE.As shown in figures 20 a-20 c, when 330nm is excited, when THF/ it is water-soluble Water content (f in liquidw) less than 50% when, the fluorescence radiation of TPE-2Gd is weaker.With fwIncrease, the fluorescence of solution gradually becomes By force, high intensity is become in pure water solution to light, obvious AIE effects are shown.The photo of Figure 20 A is clearly demonstrated, with FwGradually increase in the THF/ aqueous solution, the fluorescence of TPE-2Gd is strengthened.
From Figure 20 C it is noted that when stain concentration from increase to 100 μM for 1 μM when, TPE-2Gd is glimmering in pure water Luminous intensity increased one times.Micella can be formed when speculating amphipathic TPE-2Gd molecules high concentration.Due to AIE properties, TPE- The critical micelle concentration (CMC) of 2Gd can be estimated using fluorescence intensity.When concentration is less than CMC, dyeing agent molecule can To be preferably dissolved in solution, therefore not luminescence.When stain concentration is higher than 10 μM, solution lights.Such as Figure 21 A-21C institutes Show, the correlation curve between fluorescence intensity and stain concentration forms two, and the crosspoint of two lines provides CMC for 70 μM, should Value is more much lower than the value (CMC=8.2mM) of lauryl sodium sulfate, caused by the strong-hydrophobicity mainly due to TPE aglucons. Even so low CMC is also ensured that under blood flow dilution formed in vivo nanometer polymer.As shown in Figure 22 A and 22B, Confirmed by transmission electron microscope and eletrokinetic potential Particle Size Analyzer and form nanometer polymer under high stain concentration.Contain The effective diameter of glue beam is 164.9nm, and 70nm is reduced to after dehydration.The particle diameter of nanometer polymer is suitable for cell in vitro intake With body-internal-circulation and bio distribution.
A kind of commercial Gd- base MR (Gd-based MR) contrast preparation ratified by FDAIt is a kind of allusion quotation The extracellular fluid reagent of type, can Rapid Circulation in cell outskirt or tissue space.On the other hand, TPE-2Gd can be poly- with nanometer The form of compound is entered in tumour cell, is imaged into line justification by living cells.HeLa cells are cultivated by 30 μM of TPE-2Gd 4 hours, TPE-2Gd entered to that this is intracellular, and by blue-fluorescence cytoplasm district is illuminated.In order to be further characterized by TPE-2Gd's Dyeing area, using PI as counterstain.PI is the nuclear nuclei dyeing toner that can dye fixed cell.Such as Figure 23 A- Shown in 23D, clearly illustrate that TPE-2Gd is selective in perinuclear blue-fluorescence and only cytoplasm district is dyeed.TPE-2Gd Nanometer polymer living cells is internalized into by the approach of endocytosis so that TPE-2Gd can be on a cellular level Tumour is followed the trail of, be compensate forThe defect of tumour is followed the trail of in tissue level.
Using mtt assay TPE-2Gd is determined in HeLa intracellular toxicity.Expose cells to the TPE- of variable concentrations 2Gd (0,15 μM, 30 μM, 45 μM and 60 μM) 4 hours, then cultivates 24 hours, for assessing nanometer in fresh culture medium The internalization of polymer cell proliferation affects.As shown in figure 24, when the concentration of TPE-2Gd is less than 30 μM, typically do not have Toxicity, after being processed with coloring agent, about 98.8% cell is all living.Even if concentration increases to 60 μM, compare cell imaging The working concentration of experiment is higher by 2 times, and cell survival rate still there are about 87.8%.This result shows that TPE-2Gd is that biology can phase Hold for cell imaging, and be expected to further carry out In vivo study.
On the other hand, in order to detect whether TPE-2Gd is effective MRI contrast agent, using 3.0T Magnetic resonance imagings (MRI) instrument is at room temperature according to Gd3+The longitudinal relaxation time of TPE-2Gd or spin lattice (T in the concentration mensuration aqueous solution1)。 As shown in figure 25, with the increase of TPE-2Gd concentration in cushioning liquid, the signal strength signal intensity (brightness) of mixture becomes strong, and identical Gd3+ConcentrationIt is similar.As shown in figure 26, the relaxivity for determining TPE-2Gd is 3.36 ± 0.10mM-1·s-1,Relaxivity be 3.70 ± 0.02mM-1·s-1, relaxivity referred in the contrast preparation of per unit concentration The paramagnetism composition of spin lattice.WithCompare, TPE-2Gd has high relaxation speed, show that TPE-2Gd can be with Strengthen the relaxation rate of its neighbouring water proton, and then cause signal strength signal intensity to strengthen.Such as Figure 27, Figure 28 A, Figure 28 B and Figure 29 institutes Show, TPE-2GD is used as nano-particle, and the half-life in blood is longer, can be used for extending liver and cardiac MRI imaging when Between window.
