Reducing bioactivation potential by chemical design
Continuing the theme of an earlier post, an excellent article in Current Topics in Medicinal Chemistry looks at the issue of adverse drug events associated with the formation of reactive intermediates. The authors (from Novartis) give some background to drug-related … Continue reading →

Structural Alert: Benzimidazoles
An informative letter, just published by a team from Novartis, highlights the risk of suitably substituted benzimidazoles acting as latent precursors to reactive ortho-iminoquinone species. The example they report (see structure on left below) was Ames positive and exhibited time-dependent inhibition … Continue reading →
