ABSTRACT
INTRODUCTION:
Adrenomedullin (AM) is a peptide responsible for many physiological processes including vascular health and hormone regulation. Dysregulation of AM signaling can stimulate cancers by promoting proliferation, angiogenesis and metastasis. Two AM receptors contribute to tumor progression in different ways. Adrenomedullin-1 receptor (AM1R) regulates blood pressure and blocking AM signaling via AM1R would be clinically unacceptable. Therefore, antagonizing adrenomedullin-2 receptor (AM2R) presents as an avenue for anti-cancer drug development. AREAS COVERED We review the literature to highlight AM's role in cancer as well as delineating the specific roles AM1R and AM2R mediate in the development of a pro-tumoral microenvironment. We highlight the importance of exploring the residue differences between the receptors that led to the development of first-in-class selective AM2R small molecule antagonists. We also summarize the current approaches targeting AM and its receptors, their anti-tumor effects and their limitations. EXPERT OPINION As tool compounds, AM2R antagonists will allow the dissection of the functions of CGRPR (calcitonin gene-related peptide receptor), AM1R and AM2R, and has considerable potential as a first-in-class oncology therapy. Furthermore, the lack of detectable side effects and good drug-like pharmacokinetic properties of these AM2R antagonists support the promise of this class of compounds as potential anti-cancer therapeutics.Palavras-chave
