Inal microsomes were not offered in the vendor. Taken together, nitric oxide formation by way of conversion of DB844 to MX might not clarify the observed GI toxicity, but possibility exists exactly where an elevated CYP1A1/1B1 as a result of induction (e.g., by dietary phytochemicals27) leads to MX formation and nitric oxide release from DB844. It’s not yet recognized if this intramolecular rearrangement and resulting nitric oxide release can occur with other amidine analogs (e.g., benzamidoximes/N-hydroxylated benzamidines). If true, it may contribute towards the understanding of toxicity caused by other benzamidoxime- or benzmethamidoxime-containing molecules, such as ximelagatran, a direct thrombin inhibitor that failed in clinical trials as a result of idiosyncratic liver injury.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptCIAcknowledgmentsThis function was supported in component by a grant to the Consortium for Parasitic Drug Improvement (CPDD; http:// thecpdd.org) from the Bill and Melinda Gates Foundation and by an NIH grant R01GM089994 (MZW).
