Description

Pegylation lapatinibditosylate and injection thereof and preparation method
Technical field
The present invention relates to the conjugate field of lapatinibditosylate, in particular to Pegylation lapatinibditosylate and injection thereof and preparation method.
Background technology
Lapatinibditosylate (Lapatinib) is a kind of oral small molecule epidermal growth factor receptor tyrosine kinase inhibitor, be mainly used in associating capecitabine treatment ErbB-2 overexpression, and previously accepted the late period of anthracycline, taxol or Herceptin treatment or metastatic mammary cancer, come into the market in 2007 by U.S. FDA approval.Lapatinibditosylate can suppress cancer stem cell, as U87-MG cancer of the brain stem cell and SUM225 breast carcinoma stem cell.
The molecular weight of lapatinibditosylate is 581.06, belong to small molecule anti-cancer drug, there is water-soluble difference, biologically stable is poor, toxic side effect is large shortcoming, and micromolecular lapatinibditosylate is by diffusing into cancer cells or cancer stem cell can be gone out by p-glycoprotein membrane pump, and then causes resistance.And the polymer coupling anticancer stem cell small-molecule drug of long-acting slow-release greatly can reduce the toxicity of small-molecule drug, greatly promote its water-soluble and biologically stable, strengthen its passive targeting, relative to antibody coupling anticarcinogen (ADC), antibody anticarcinogen, the antibody of antibody anticancer stem cell drugs or immunotherapy is cheap, and cancer cells or the extremely strong resistance of cancer stem cell can be avoided, this is because polymer coupling anticarcinogen or polymer coupling anticancer stem cell drugs have larger molecular weight, cancer cells or cancer stem cell can only be absorbed it by endocytosis and pinosome.But for be anticarcinogen and the polymer coupling technology of the lapatinibditosylate of anticancer stem cell drugs report and product not yet find.
In view of this, special proposition the present invention.
Summary of the invention

2, drug resistance tests repeatedly group: through the observation of 1 week, compare with physiological saline, hair has some setbacks, brightless smooth.Body weight change no significant difference; Without nausea,vomiting,diarrhea, appetite, maldigestion, xerosis cutis, fash, red swelling of the skin, scratch where it itches, pain, backache, expiratory dyspnea, the situation such as tired and insomnia occur.Intracorporeal organ naked eyes viewing indifference.Mice sleep and enliven situation indifference; Mouse anus and defecation situation indifference, do not have diarrhoea situation.
The mouse live body curative effect of experiment 3, polyethylene glycol conjugation lapatinibditosylate
Mouse becomes knurl: SK-BR-3 cell cultures is to after several bottles, and trysinization, uses serum-free 1640 substratum resuspended after PBS washing counting, be that solution density reaches 1*10E7/mL, trash ice placed stand-by.Hair is shaved at NOD mouse inoculation position, and use disposable sterilized injector inoculation SK-BR-3 cell, 0.2mL/ props up, and uses cotton ball soaked in alcohol wiping to kill the cell of spilling, put back in cage and normally raise after inoculation.
Live body is treated:
Former medicine LPT: physiological saline disperses, and 1g is scattered in 200mL physiological saline, dispersed.Oral administration gavage 20mg/kg at noon.7-129: be divided into and respectively inject a 10mg/kg (conversion dosage) in the morning and afternoon, interval time, 6-7 hour, amounted to 20mg/kg.
Experiment grouping: former medicine multiple dosing group; 7-129 multiple dosing group; Physiological saline group.
Experimental result
As shown in figure 24, compared with former medicine, 7-129 shows higher inhibition to tumour to tumor growth curve, and illustrate that lapatinibditosylate is after Pegylation, drug effect significantly improves.
