- injection administration can be omitted in the stomach compared to oral administration can reduce the loss of the drug and absorption time, so it is particularly widely used in the treatment of intractable diseases such as cancer or diabetes diseases that require effective drug treatment.
- injectable drugs need to be water-soluble, and many intractable drugs are poorly soluble in water. Therefore, in order to solubilize these, various kinds of additives such as surfactants are used. In this case, many side effects occur and the treatment effect is greatly limited.

After the micelle stability in aqueous solution, intravenous injection experiments were performed. First of all, the dostaxel anticancer agent prepared in Example 1 of the present invention was obtained as a powdered micelle, but the dostaxel anticancer agent prepared in Example 1 of Korean Patent No. 0567397 was obtained in an oily liquid form.
- Example 1 of Korean Patent No. 0767397 was about 3 days. After most of the dostaxel drug was precipitated separated from the phosphazene micelle, but the solution of Example 1 of the present invention was not observed at all, even after three months.
- the AUC (Area under the curve) value indicating the bioavailability of the drug is about 2 times higher than the micelle-type dotaxel anticancer drug (0.664) of the taxotere (0.360).
- taxane-type anticancer drugs are very hydrophobic and are removed very quickly by transport proteins in the blood, unlike other anticancer drugs such as platinum complexes, the double half-life and bioavailability of the drug is a great result.
- Test animal Korean nude mouse CAnN.Cg-Foxn1nu / CrljOri was used per group, 5 cancer cell lines used were MDA-MB-231, breast cancer, excipient placebo (Placebo), and positive control.
- In vivo anticancer effects were compared at the optimal dose of 15 mg / kg and two different doses of phosphazene micelle-type docetaxel of 5 mg / kg and 15 mg / kg of Example 6 as the test substance. It was.
- the breast cancer cell line is transplanted into nude mice, and the volume of cancer tissue is 80-100 mm. 3
- the drug was administered three times on the 1st, 5th, and 9th days according to the above dose, and the growth rate of the cancer tissue was measured for 5 weeks, and is shown in FIG. 4.
- Taxotere shows the complete regression of cancer tissue as expected at 15 mg / kg of the optimal dosage reported in the literature, showing that the phosphazene micelle type dotaxel (denoted DTX) In some cases, the same 15 mg / kg dose, as well as the minimum dose of 5 mg / kg, shows complete cancer tissue healing.
- the results of these animal studies show that phosphazene micelle-type docetaxel can potentially reduce the therapeutic dose of taxotere used by the current clinical trials by one third, which is very innovative.
- these experimental results are in agreement with the results of the bioavailability parameter (AUC) of phosphazene micelle type dotaxel almost doubled in taxotere in the blood metabolism test of Experimental Example 1.
- AUC bioavailability parameter
- mice Male ICR mice, weighing 20-22 g at 6 weeks of age, were acclimated at 20 ° C. and 60% humidity for 5 days and tested according to OECD guideline 423. That is, the test substance was dissolved in physiological saline, and in the case of Taxotere, 5, 30, 50, 100 mg / Kg doses, and the phosphazene micelle-type docetaxel containing 10% of the dostaxel of Example 6, 5, 50 3, 4, 300, 500, 1000 and 2,000 mg / Kg doses were administered intravenously, followed by body weight change and survival for 2 weeks. After 2 weeks, a biopsy was performed and LD 50 values were calculated according to OECD guideline 425. It was.
- the dostaxel LD 50 value of Taxotere prepared with polysorbate 80 is 28 mg / Kg
- the dostaxel prepared with phosphazene micelle of Example 6 has an LD 50 value of 75 mg / Kg. It was calculated to increase three times. The reason for this three-fold reduction in acute toxicity is that in the case of Taxotere micelles that have been micelles, micelles are immediately broken in the body immediately after injection, and doxtaxel is released into the blood. Due to its stability, it is released slowly from micelles. Therefore, acute toxicity is alleviated and bioavailability is increased to increase drug efficacy.
- IV cannula was administered to the jugular vein for the administration of the test substance at a rate of 10 mg / Kg / min. Administered via a previously secured vein using a controlled syringe pump. Anesthetic induction was evaluated in the following order, and the amount of propofol that entered the end point of the anesthetic induction was determined as the total dose.
- Example 11 the phosphazene micelle type propofol is the anesthesia time than the Diprivan ® propofol injections of the lipid emulsion to be used as the current product being slightly delayed There This fact the conventional propofol in lipid emulsion injection immediately after the Compared to the release of the emulsion into the blood and reaction with the pain receptor, propofol trapped in the phosphazene micelle does not immediately flow into the blood immediately after injection, but is absorbed into the tissue in micelle form and delayed anesthesia.
- the propofol trapped in the phosphazene micelle of the present invention rather than the lipid emulsion propofol, which is a problem at present, is expected to contribute significantly to pain relief by reducing the reaction time with the pain receptor in the blood.
