Use of mestranolMestranol is the 3-methyl ether of ethinylestradiol. It was the estrogen used in many of the first oral contraceptives.Target: Estrogen Receptor/ERRMestranol is absorbed very rapidly from the digestive tract and maximum plasma levels are attained in 1-4 hours, the majority at 1-2 hours. Detectable levels of mestranol are present 24 hours postingestion in 58% of subjects after a 50 μg dose and in 79% after a 100 μg dose. At all dose levels, highest plasma mestranol levels and area under the curve of plasma levels (AUC) occurred in Sri Lankan women, and lowest plasma levels in Nigerian women, even when corrected for body surface differences [1]. |

Cheminformatics analysis of assertions mined from literature that describe drug-induced liver injury in different species.
Chem. Res. Toxicol. 23 , 171-83, (2010) Drug-induced liver injury is one of the main causes of drug attrition. The ability to predict the liver effects of drug candidates from their chemical structures is critical to help guide experimental... |

Translating clinical findings into knowledge in drug safety evaluation--drug induced liver injury prediction system (DILIps).
J. Sci. Ind. Res. 65(10) , 808, (2006) Drug-induced liver injury (DILI) is a significant concern in drug development due to the poor concordance between preclinical and clinical findings of liver toxicity. We hypothesized that the DILI typ... |
