Synthesis, biological evaluation and SAR of 3-benzoates of ingenol for treatment of actinic keratosis and non-melanoma skin cancer
摘要:
Ingenol 3-benzoates were investigated with respect to chemical stability, pro-inflammatory effects, cell death induction and PKC delta activation. A correlation between structure, chemical stability and biological activity was found and compared to ingenol mebutate (ingenol 3-angelate) used for field treatment of actinic keratosis. We also provided further support for involvement of PKC delta for induction of oxidative burst and cytokine release. Molecular modeling and dynamics calculations corroborated the essential interactions between key compounds and C1 domain of PKC delta. (C) 2013 Elsevier Ltd. All rights reserved.
