The activity of resisting tumor metastasis of the measurement compound 6 of embodiment 12
Lewis murine lung cancer cell (LLC the is purchased from ATCC) inoculation of this rating model, selects DMEM culture medium (to contain 10% Fetal calf serum through inactivating, 1 × 105U/L penicillin and 100mg/L streptomysin), it was passed according to attached cell cultural method every two days In generation, is primary, enrichment of cell.Vitellophag when cell growth state is good and is in logarithmic growth phase, is adjusted thin with physiological saline Born of the same parents' density is to 1 × 107A/mL.The dyeing of placenta indigo plant, makes viable count>95%.Take inbred strais C57BL/6 male mice (SPF Grade, 20 ± 2g of weight), the fixed mouse of left hand.It is sterilized with 75% Mice Hepatocytes Injured by Ethanol right fore skin of axillary fossa.It is sterile that the right hand holds 1mL LLC tumor cell suspension is subcutaneously injected toward mouse armpit in syringe, and every mouse injects 0.2mL.After mouse inoculation 10 days, grow The tumour of diameter about 4-5mm is knurl source.The Lewis lung cancer tumor-bearing mice etherization of inoculation 10 days, cervical dislocation are put to death.With 75% ethyl alcohol impregnates 10min, and knurl is removed in disinfection on superclean bench.Select well-grown tumor tissues sterile flat It shreds, is placed in the tissue homogenizer of glass manufacture in ware.The ratio for being again 1 to 3 (g ratio mL) than physiological saline volume in tumor mass The physiological saline that heating degree is 4 DEG C, is lightly ground and cell suspension is made.Cell suspension crosses 200 mesh cell sieve single cell suspensions. With the cell density of physiological saline tune single cell suspension to 1.5 × 107A/mL.The dyeing of placenta indigo plant, makes viable count>95%. Left hand fixes inbred strais C57BL/6 male mice, is sterilized with 75% Mice Hepatocytes Injured by Ethanol right fore skin of axillary fossa.The right hand holds 1mL Tumor cell suspension, every injection 0.2mL is subcutaneously injected in mouse armpit in asepsis injector.Mouse grows diameter 4- after inoculation 10 days Mice Inoculated is grouped by the tumour of 5mm at random by the gross tumor volume measured.Every group of 12 mouse.The 11st day of inoculated tumour is small Mouse or the normal saline solution (dosage be 20 μm ol/kg/ days) or oral administration of compound 6 for taking orally generally acknowledged anti tumor translocation peptide RGDS Normal saline solution (dosage be 0.5 μm ol/kg/ days) or the normal saline solution of oral administration of compound 8 (dosage is 5 μm of ol/ Kg/ days) or oral normal saline (dosage is 10mL/kg/ days), 1 medicine is given daily, successive administration 12 days, is measured every three days And record gross tumor volume.The next day measurement knurl product of last time administration, etherization cervical dislocation are put to death, and the tumour of mouse is taken to claim Weight takes the lung of mouse and calculates the burrknot number of tumour lung transfer.It is examined with t for statistical analysis to data.It the results are shown in Table 1. In 0.5 μm of ol/kg dosages for Compound 6 not only effectively inhibit neoplasm lung metastasis, and activity and dose ratio it high 40 times RGDS and its high 10 times compound 8 of dose ratio do not have significant difference.These statistics indicate that, the present invention has significant technology to imitate Fruit.
The activity of resisting tumor metastasis of 1 compound 6 of table
A) with physiological saline ratio p<0.01, compare p with RGDS and compound 8>0.05;N=11
Embodiment 13 measures the neoplasm growth activity of compound 6
Adriamycin, compound 8 and compound 6 are all used into physiological saline solution before measurement, are administered for S180 mouse.In nothing It is taken in collarium border and is inoculated in male ICR mouse 10 days eugonic S180 ascitic tumor fluids, with normal saline dilution at (1:2) Liquid is sufficiently mixed, and by 0.2% Trypan Blue of tumor cell suspension Fresh, white blood cell count(WBC) method is pressed after mixing It counts, dye blue person is dead cell, and tinter is not living cells.By viable count/4 × 10 in cell concentration=4 block plaids4× Extension rate=cell number/mL calculates cell density, by cell survival rate=viable count/(viable count+dead cell number) × 100% calculates cell survival rate.It is 2.0 × 10 that density, which is made, with homogenate method in tumor liquid by survival rate greater than 90%7A/mL's is thin Born of the same parents' suspension.The cell suspension inoculation is subcutaneous (0.2mL/ is only) in mouse right axillary, manufactures S180 tumor-bearing mice.S180 after inoculation for 24 hours Normal saline solution (dosage oral administration of compound 8 for 2 μm of ol/kg/ days g) or daily of adriamycin is injected intraperitoneally in tumor-bearing mice daily Normal saline solution (dosage be 5 μm ol/kg/ days) or the normal saline solution of daily oral administration of compound 6 (dosage is 0.5 μ Mol/kg/ days).It is administered once a day, successive administration 12 days.The next day measurement knurl product of last time administration, etherization are de- Cervical vertebra is put to death, and is then fixed mouse right axillary tumor location with tweezers, is cut off skin blunt separation tumour and weigh.Use knurl weight (mean value ± SD g) indicates curative effect, and data are examined with t and variance analysis.It the results are shown in Table 2.In 0.5 μm of ol/kg dosages for Compound 6 not only effectively inhibit tumour growth, but also activity does not have significant difference with its high 10 times compound 8 of dose ratio.These Statistics indicate that the present invention has significant technical effect.
Influence of 2 compound 6 of table to S180 mice tumors grew
A) with physiological saline ratio p<0.01, compare p with compound 8>0.05;N=12.
The anti-inflammatory activity of the measurement compound 6 of embodiment 14
Because mouse ear swelling caused by dimethylbenzene is acknowledged as acute inflammation model, the present invention causes in dimethylbenzene Mouse ear swelling model on measure compound 6 therapeutic effect.Because aspirin is the positive drug for treating acute inflammation, institute Select aspirin as positive control drug using the present invention.ICR male mice (20 ± 2g of weight) is quiet in the environment that temperature is 22 DEG C Breath 2 days, free water and feed.Later, physiological saline group (dosage is 0.2mL/), aspirin group (dosage are randomly divided into For 1.11mmol/kg), 8 groups of compound (dosage is 5 μm of ol/kg) and 6 groups of compound (dosage is 0.5 μm of ol/kg), every group 12 Mouse.Mouse is by place group or oral normal saline or oral aspirin or oral administration of compound 8, or oralization when measurement Close object 6.After 30min is administered, the left auricle toward mouse uniformly smears 30 μ L dimethylbenzene, and mouse receives etherization after 2h, and break neck It puts to death, cuts two ears of left and right, take round auricle in the same position of two ears with the punch of 7mm, weigh, it is poor to find out two ear swellings Value is used as swelling.That is swelling=left ear disk weight-auris dextra disk weight.It the results are shown in Table 2.Under 0.5 μm of ol/kg dosage Compound 6 not only effectively inhibits mouse ear swelling caused by dimethylbenzene, but also activity and its high 2220 times Ah Si of dose ratio Woods and its high 10 times compound 8 of dose ratio do not have significant difference.These statistics indicate that, the present invention has significant technology to imitate Fruit.
