This study aim to investigate effects of 4(3H)quinazlonones-2-ethyl-2-phenyl ethyl (QEPE) as a new quinazolinone on brain development of newborn Balb/C mice. Pregnant Balb/C mice (n=8) were divided into 3 groups of control, receiving distilled water, sham,treated with 0.05% methyl cellulose (the solvent)and experimental group, receiving one of the most effective dose of 100mg/kg/body weight of 4(3H)quinazlonones-2-ethyl-2-phenyl ethyl (QEPE), by IP injections on days 8 th to 15 th of gestation.

Data demonstrated an increase in the number of astrocytes of cerebral cortex and medulla of newborn mice of treated groups. Confirming the results, statistical studies showed no significant differences between the morphology of newborn mice of control, sham and treated groups'astrocytes, but there were significant differences in the number of astrocytes of newborn mice of group treated with QEPE. In conclusion, astrocyte hyperplasia decreases toxic effects of QEPE by passing through blood-brain barrier. Keywords: 4(3H)quinazlonones-2-ethyl-2-phenyl ethyl (QEPE), Brain, Balb/C mice.
