Lysine as a potential low molecular weight angiogen: its clinical, experimental and in-silico validation- A brief study

Globally, the area of angiogenesis is dominated by investigations on anti-angiogenic agents and processes, due to its role in metastatic cancer treatment. Although, the area of ischemic tissue reperfusion is having much bigger demand and foot-mark. Following clinical failure of VEGF (Vascular endothelial growth factor) as a potential agent for induction of a controlled angiogenic response in ischemic tissues and organs, the progress is reasonably quiet as for new low molecular weight (LMW) angiogen molecules and their clinical applications are concerned. Basic amino acid Lysine has been observed to have profound angiogenic property in ischemic tissues, which is controlled, reproducible, time bound and without any accompanying reperfusion damage. In this study, the basic amino acid Lysine has been suggested as a LMW-angiogen, where it has been proposed to have a molecular binding property between VEGF and VEGF receptor (VEGFR). Here, the molecular adhesive hypothesis is being probed and confirmed both in the clinical and lab conditions through induced angiogenic response in tissue repair and in chick chorio allantoic membrane (CAM), respectively; and in dry-docking experiments (in-silico studies).
