5、arget DNA alkylator 1体外研究 Temozolomide (TZM) is a methylating agent that crosses the blood-brain barrier and is indicated formalignant gliomas and metastatic melanomas. Temozolomide is effective against tumor cells that arecharacterized by low levels of O6-alkylguanine DNA alkyltransferase (OGAT) an

6、d a functional mismatchrepair system (MR) 1. Determination of the IC50 for Temozolomide (TZM) in different cell lines gave valuesranging from 14.1 to 234.6 M that fell into two clearly differentiated groups: cell lines with low IC50 values(50 values (100 M), which include SF268 (147.22.1 M) and SK-N

7、-SH cells (234.62.3 M) 2.体内研究 Temozolomide (TZM), as a single agent, does not significantly increase mdian survival time (MST) withrespect to control. Noteworthy, intracranial injection of NU1025, immediately before the administration of 100or 200 mg/kg Temozolomide, significantly increases lifespan

8、s with respect to controls or to groups treatedwith Temozolomide only. When Temozolomide is fractionated, the increase in lifespan (ILS) obtained withthis schedule is higher than that observed when NU1025 is combined with a single injection ofTemozolomide (statistical comparison of survival curves:
