These inhibitors react with their target proteins to form a covalent complex in which the protein has lost its function.The majority of these successful drugs, which include penicillin, omeprazole, clopidogrel, and aspirin were discovered through serendipity in phenotypic screens (Potashman & Duggan, 2009).

Furthermore, there are no specific tools for predicting the occurrence of hepatotoxicity induced by these drugs.

Therefore, there has been considerable interest in elucidating the mechanism(s) of Abeta neurotoxicity.

Here, we review the molecular signaling pathways involved in Abeta-induced cell death, including signaling through the neuronal nicotinic receptor and the Abeta-triggered generation of reactive oxygen species (ROS) leading to the activation of the c-jun N-terminal kinase (JNK), and the ensuing phosphorylation of p66Shc and inactivation of the Forkhead transcription factors.

Methimazole and propylthiouracil have been used in the management of hyperthyroidism for more than half a century.

However, hepatotoxicity is one of the most deleterious side effects associated with these medications.

Genome-wide identification of the mechanism of action (Mo A) of small-molecule compounds characterizing their targets, effectors, and activity modulators represents a highly relevant yet elusive goal, with critical implications for assessment of compound efficacy and toxicity.

Current approaches are labor intensive and mostly limited to elucidating high-affinity binding target proteins.The purpose of this article is to give an overview on possible susceptibility factors in liver injury induced by antithyroid agents.Age, gender, metabolism characteristics, alcohol consumption, underlying diseases, immunologic mechanisms, and drug interactions are involved in enhancing antithyroid drugs-induced hepatic damage.
