  ageladine A analogs that include 2-aminoimidazo[4,5-c]azepines (seven-membered rings) and 2-amino-3H-imidazo[4,5-c]pyridine (six-membered rings) derivatives were synthesized and evaluated for their anticancer effects against several human cancer cell lines and MMP-2 inhibition in vitro. Only compounds possessing the aromatic azepine (seven-membered ring) core showed anticancer activity with IC50 values

  A bio‐inspired cascade reaction has been developed for the construction of the marine natural product ageladine A and a de novo array of its N1‐substituted derivatives. This cascade features a 2‐aminoimidazole formation that is modeled after an arginine post‐translational modification and an aza‐electrocyclization. It can be effectively carried out in a one‐pot procedure from simple anilines or guanidines

  A one-pot synthesis of ageladine A and analogues is reported. The key Pictet - Spengler reaction between 2-aminohistamine and aryl aldehydes has been successfully utilized for the synthesis of the natural product and 14 analogues. These compounds were screened for their matrix metalloprotease (MMP) and kinase inhibition to develop the first structure-activity relationship of ageladine A analogues. One compound, which showed significant kinase activity but little MMP inhibitory activity, was found to be highly active in an antiangiogenic screen, suggesting that the angiogenic activity of ageladine A is not associated with MMP inhibition but rather kinase inhibitory activity. Cytotoxicity was excluded as a mode of action by the assay of ageladine A and an analogue against 60 human cell lines.
