DNA-PK cancer ratio Ratio to that of amonafide

Question. A comparison of the activity t of UNBS3157 DNA-PK cancerDNA-PK cancer chemical structure, mitoxantrone, taxol and two models of human orthotopic hormonrefrakt Another PC-3 and DU145 prostate carcinomas. Medication administration began 7 days after transplantation of tumor cells, so that the treatment had begun when tumors already started to develop means. All compounds were administered with a schedule of three doses per week for 4 weeks. Control Mice Who again U the vehicle are shown by black circles. Each treatment group consisted of nine animals. Consisting of an impact on the survival of M Mice with orthotopic PC 3 xenografts. UNBS3157 and amonafide were administered orally, w During intravenous mitoxantrone was S at a dose of 2.5 mg / kg. UNBS3157 impact on the survival of depleted uranium 145 in M Mice with orthotopic xenografts.
AB1010 UNBS3157 and amonafide were at 20 mg / kg IV or orally 40 mg / kg administered with taxol in both experiments, only iv 20 mg / kg. Flight neoplasia. 10, No. 6, 2008 naphthalimide and treatment of prostate cancer Mijatovic et al. 577 reported that 10 mg / kg dose UNBS5162 as effective as 20 mg / kg. We have decided, 10 mg / kg dose for chronic administration in vivo using xenograft studies, w While the 20 mg / kg dose in the pharmacokinetic study. UNBS5162 administration before or after taxol Changed nothing on the therapeutic benefits of Taxol alone. In contrast, the administration UNBS5162 along taxol to 3 PC orthotopic tumor-bearing M mice significantly increased the therapeutic benefits of Taxol alone ht.
It is important to note that the treatment does not consist of transplantation started, but after the tumors and has grown considerably. Thus, the data will relate to the reduction of tumor growth and metastatic processes in these orthotopic Table 1 IC50 values for inhibition of in vitro growth of human cancer cell lines and UNBS3157 UNBS5162.

IC 50 values reported mean values of six separate determinations are calculated. SEM values are reported for reasons of clarity.
It is also noted that the h HIGHEST value was calculated less than 5% of their average value SEM. Figure 2 UNBS5162 is the product of hydrolysis of UNBS3157. In vitro, a rapid and completely Requests reference requests getting to hydrolysis of UNBS3157 UNBS5162. The in vitro degradation kinetics were determined by HPLC UNBS3157 UV analysis using a 5 m Atlantis DC18, 4.6 × 150 mm analytical column and am a re S gradient, comprising: A mobile phase A: 0, 1% w ssriger formic acid and mobile phase B: 0.05% formic acid in acetonitrile, as described in Materials and methods.
