Ethynodiol diacetateS3160

Nordihydroguaiaretic acid (NDGA) (< 1.5 μM) decreases the percentage of sister chronnatid exchanges (SCEs) in human lymphocyte culture treated with ethynodiol diacetate (150 μg/mL). Since the NDGA treatment, in the presence of S9 mix, reduce the genotoxic damage by ethynodiol diacetate, the reduction may be due to the inhibition of cytochrome P450s which prevents the metabolic activation of ethynodiol diacetate or NDGA may act as a free radical scavenger. ^[1] Ethynodiol diacetate (150 μg/mL) increases sister chromatid exchanges (SCEs) and chromosomal aberrations (CAs) frequencies and inhibits lymphocyte proliferation in the presence of S9 mix in human lymphocyte. ^[2]
