How ACE inhibitors transformed the renin-angiotensin system

Area of Science:

• Pharmacology
• Cardiovascular Medicine
• Biochemistry

Background:

• The renin-angiotensin system (RAS) is crucial in cardiovascular medicine, impacting nearly 50% of patients.
• Potential applications of RAS modulation extend to diabetes, Alzheimer's disease, and cancer.

Purpose of the Study:

• To analyze the historical transformation of the RAS from academic research to clinical practice.
• To identify key scientific and clinical events driving the RAS's evolution.
• To assess the roles of chance, coincidence, and conviction in this transformation.

Main Methods:

• Historical analysis of scientific literature and clinical data.
• Review of key discoveries, including bradykinin-potentiating peptides and ACE inhibitors.
• Examination of the development pathway of synthetic RAS inhibitors like captopril and angiotensin receptor blockers.

Main Results:

• The RAS pathway led to the development of captopril and angiotensin receptor blockers, transforming cardiovascular treatment.
• The journey involved critical scientific insights and clinical validation over five decades.
• The transformation demonstrates a successful interplay between basic research, drug development, and patient care.

Conclusions:

• The evolution of the RAS represents a significant success story in medicine and pharmacology.
• Continued research into the RAS holds promise for treating complex diseases beyond cardiovascular conditions.
• The RAS transformation underscores the importance of interdisciplinary collaboration and persistent scientific inquiry.
