Abstract

We developed a novel pathway for the successful synthesis of leteprinim potassium 1, which is one of the candidate substances for treating Alzheimer’s disease, and subsequently synthesized 4 types of corresponding novel derivatives 2–5 that have hypoxanthine or 2-chloro-6-aminopurine as the nucleobase. We then determined the angiogenic activity of these compounds by using human umbilical vein endothelial cells. Compounds 1–4 showed no angiogenic potencies judging from statistical analysis, student’s t-test.
