Fig. 1 is emission spectrum of the pyrene in Soluplus dispersion liquid in embodiment 1;
Fig. 2 is tacrolimus-Soluplus self-assembled nanometer grain transmission electron microscope picture in embodiment 2;
Fig. 3 is that AIA rat paw edema is write music line in embodiment 4.
(5) specific embodiment
Technical solution of the present invention is described further below by specific embodiment, but protection scope of the present invention is not
It is limited to this.
The structural identification of embodiment 1:Soluplus self-assembled nanometer grain
Pyrene is a kind of micropolar fluorescence probe of medium, belongs to condensed-nuclei aromatics class, at room temperature, when the concentration of pyrene is less than 10- 5When mol/L, after pyrene solution excites at 335nm, there are 5 fluorescent emission electricity in 373,379,384,394 and 480nm respectively
Sub- vibration peak.The ratio between the fluorescence intensity of first electronic vibration peak 373nm and third electronic vibration peak 384nm I1/I3With pyrene point
The polarity of sub- local environment is in very strong correlation.I1/I3Smaller, the polarity of corresponding environment is smaller, i.e., hydrophobicity is stronger.Usually
Think, I1/I3The turning point of ratio is critical micelle concentration.
Precision weighs pyrene 19.62mg, and dehydrated alcohol is added to dissolve, and is diluted to 10ml measuring bottle, is configured to 1.962mg/ containing pyrene
Ml solution.Precision measures liquid 0.25ml, adds ethyl alcohol to be diluted to 50ml measuring bottle, is configured to the 9.81 μ g/ml solution containing pyrene.Precision amount
100 μ l of the liquid is taken, is placed in clean and dry test tube, volatilizes.Be separately added into containing Soluplus 0,10,50,100,150,200,
300, the dispersion liquid of 500,1000,5000,10000 μ g/ml, 37 DEG C are protected from light constant temperature oscillation 12h.In F-4600 fluorescence spectrophotometry
Meter, fixed excitation wavelength 335nm, exciting slit 5nm, transmite slit 2.5nm, sweep speed 240nm/min, 350~500nm are swept
It retouches, records launching light spectrogram, and calculate I373/I384。
It can be seen from figure 1 that the fluorescence intensity of pyrene is gradually increased with the increase of Soluplus concentration, illustrate Soluplus pairs
Pyrene has solubilization, but I373/I384The ratio between do not reduce the phenomenon that.
When Soluplus concentration is 5mg/ml, that is, there is macroscopic light blue opalescence, pass through laser granulometry
Measure the range of 0.01~80mg/ml of Soluplus concentration, average grain diameter 56nm ± 5nm.Illustrate that Soluplus is self-assembly of
Particle be in nanoparticulate form, rather than the form of micella.
Embodiment 2: the preparation method of tacrolimus-Soluplus self-assembled nanometer grain compares
Composition | Dosage |
Tacrolimus | 300mg |
Soluplus | 8000mg |
Dehydrated alcohol | 10ml |
Water for injection adds to | 100ml |
Preparation method one: tacrolimus is dissolved in dehydrated alcohol;Soluplus is dissolved in water for injection;It is stirred again in magnetic force
Mix it is lower by tacrolimus ethanol solution inject the water phase containing Soluplus in, stir evenly.
Preparation method two: tacrolimus and Soluplus are dissolved in dehydrated alcohol, under magnetic agitation, inject water for injection
In, it stirs evenly.
Partial size, encapsulation rate and the dilution stability of self-assembled nanometer grain are measured respectively.As the result is shown prepared by two methods
Self-assembled nanometer grain average grain diameter is 70nm or so, is slightly increased compared with blank nanoparticle;Encapsulation rate is 93% or more;But method
When the nanoparticle dilution of one preparation, drug leakage is easily led to, when Soluplus concentration is diluted to 0.5mg/ml from 80mg/ml,
Method one has 35% drug leakage;And method two only 21%.
Embodiment 3: the freeze-dried preparation of tacrolimus-Soluplus self-assembled nanometer grain
Preparation: tacrolimus and Soluplus are dissolved in dehydrated alcohol, under magnetic agitation, are injected in water for injection, are stirred
It mixes uniformly;Again through ultrafiltration membrane Biomax 30kD ultrafiltration, in nano suspension: fresh water for injection (1:50) ratio ultrafiltration removes
Dehydrated alcohol;Freeze drying protectant mannitol, sucrose or lactose are added, the quality dosage of freeze drying protectant is respectively water for injection
5%, 10% and the 15% of quality;It is freeze-dried freeze-dried to get tacrolimus-Soluplus self-assembled nanometer grain.
As a result: using mannitol as freeze drying protectant, complete appearance, nothing is collapsed.Other freeze drying protectant appearances exist different
The defect of degree;But redisperse and encapsulation rate are had little effect.Mannitol dosage increases, the grain after freeze-dried powder redisperse
Diameter slightly increases.Therefore freeze drying protectant is excellent with 5% mannitol.
Embodiment 4: tacrolimus-Soluplus self-assembled nanometer grain is compared with the pharmacodynamics of solution
It male SD rat 20, weight 160g or so, raises after a week, in unilateral right 100 μ L Freund of metapedes intracutaneous injection
Freund's complete adjuvant (CFA, the tubercle bacillus 5mg/mL containing inactivation) is used as the 0th day on the day of modeling.The next day measure degree of paw swelling, work as foot
Swelling > 100% is considered as rheumatoid arthritis modeling success.D7 is grouped according to the swelling of rat injection parapodum,
Every group 5, by tacrolimus dosage 10mg/kg intravenous injection give the tacrolimus self-assembled nanometer grain prepared in embodiment 2,
Solution;It is total to three times one time a day with control group blank self-assembled nanometer grain, physiological saline.
It measures the toes volume of same rat injection side and opposite side per daily drainage during administration and weighs in, give
The next day after medicine, measures.Concrete operations are as follows: using at the ankle-joint top about 1cm of rat hindleg as water-immersed online, fixation
Rat respectively immerses the left and right hind leg of rat in measuring appliance, and the weight change value of water is as big divided by the density of water in container
The water-immersed sufficient volume of mouse.Same rats with bilateral compares enough, calculates swelling, and formula is as follows:
Swelling=(Vt-Vt ')/Vt ' × 100
Vt: the t days injection parapodum volumes after modeling
Vt ': the sufficient volume of sufficient opposite side is injected within the t days after modeling
From result (Fig. 3) as it can be seen that when dosage is identical, tacrolimus self-assembled nanometer grain group is significantly dropped compared with solution group
Low the degree of paw swelling of AIA rat (p < 0.05).And blank self-assembled nanometer grain and physiological saline group are swollen almost without foot is reduced
The effect of expansibility.
