[0001] Citation of relevant applications
[0002] This invention claims priority to Chinese patent application No. 202111228856.0, filed on October 21, 2021, entitled "A dual antagonist and its use therein", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This invention relates to a class of novel compounds with dual antagonistic effects on angiotensin II receptors and endothelin receptors, and their use in the preparation of pharmaceuticals. Background Technology
[0004] Angiotensin II (AngII) and endothelin-1 (ET-1) are two potent endogenous vasoactive peptides believed to play roles in controlling vascular tone and pathological tissue remodeling associated with various diseases. There are four subtypes of angiotensin II receptors: AT1, AT2, AT3, and AT4. AT1 and AT2 are predominant, with AT1 receptors mediating almost all pathophysiological functions of angiotensin II receptors. Angiotensin II receptor antagonists, as systemic antihypertensive drugs, have demonstrated advantages such as high affinity, high selectivity, oral efficacy, long half-life, and good tolerability. Endothelin is a potent vasoconstrictive vasoactive peptide that plays a crucial role in maintaining vascular homeostasis. Current technologies have identified various endothelin receptors (such as ETA, ETB1, ETB2, and ETC), among which ETA has been the most extensively studied, and its antagonists can be used to treat hypertension, pulmonary hypertension, chronic kidney disease, and atherosclerosis.
[0005] Preclinical and initial clinical data suggest that simultaneous blockade of angiotensin II and endothelin 1 at their respective receptors AT1 and ETA may offer improved treatment options for several cardiovascular diseases compared to using either mechanism alone. Dual antagonists of angiotensin II and endothelin receptors exhibit antagonistic effects against both receptors, demonstrating better efficacy and broader applicability than single angiotensin II or ETA receptor antagonists, representing a potential class of drugs for conditions such as hypertension or kidney disease. While a series of dual antagonists of angiotensin II and endothelin receptors have been disclosed in publications such as WO2000001389A1 and CN101891735A, further development is needed to develop dual antagonist drugs with better activity, higher selectivity, better water solubility, and fewer drug-drug interactions.
