Key result
Oral administration of the novel angiotensin receptor neprilysin inhibitor S086 effectively reduced blood pressure and alleviated target organ injury in spontaneously hypertensive rats.
Why the study?
To develop S086 as a novel ARNi and evaluate its protective effects on target organs in preclinical animal models.
Does S086 reduce blood pressure and alleviate target organ injury in spontaneously hypertensive rats?
Does S086 reduce blood pressure and alleviate target organ injury in spontaneously hypertensive rats?
The novel ARNi S086 demonstrates protective effects against target organ injury and reduces blood pressure in a hypertensive rat model.
Hypothesis-generating in hypertensive rats; leaves open translation of S086 effects to human disease.
BACKGROUND: Hypertension is a clinical syndrome characterized by elevated systemic arterial blood pressure associated with injury to the heart, kidney, brain, and other organs. Angiotensin receptor neprilysin inhibitors (ARNi), including angiotensin receptor blockers (ARBs) and neprilysin inhibitors (NEPi), have been shown to be safe and effective at reducing blood pressure and alleviating development of target organ injury. This study was used to develop S086 as a novel ARNi and conducted preclinical studies in animal models to evaluate the protective effects of S086 on target organs. METHODS: This study used a 14-month-old spontaneously hypertensive rat (SHR) model to evaluate the protective effects of S086 on the cardiovascular system and organs such as heart and kidney by blood pressure monitoring, urine and blood examination, pathological examination, and immunological index detection. RESULTS: After administering S086 orally to the SHR, their blood pressure and levels of renal injury indicators such as serum creatinine and urinary microalbumin were reduced, and myocardial cell necrosis and cardiac fibrosis of the heart were significantly improved. In addition, there were also significantly improvements in the histological lesions of blood vessels and the kidneys. CONCLUSIONS: The findings showed that S086 effectively reduced the blood pressure of SHR and had effects on alleviating development of heart, blood vessels and kidney.

Xiao et al. (2023) studied Hypertension. S086 was evaluated on Blood pressure and target organ injury (renal injury indicators, myocardial cell necrosis, cardiac fibrosis). Oral administration of the novel angiotensin receptor neprilysin inhibitor S086 effectively reduced blood pressure and alleviated target organ injury in spontaneously hypertensive rats.
