  Novel inhibitors of the sodium–calcium exchanger: benzene ring analogues of N-guanidino substituted amiloride derivatives

  摘要：

  A series of N-guanidino substituted 2,4-diamino-5-carbonylguanidine molecules related to amiloride were synthesised and, evaluated for their ability to inhibit the sodium-calcium exchanger in rat insulinoma cells (RINm5F) and human platelets. Specific chemical pathways were used to prepare the benzene derivatives designed as bioisosteric analogues of the pyrazine derivatives of amiloride. Several so-called 'simplified analogues', where some substituents of amiloride were omitted or replaced, were also prepared and included in the biological evaluation. The inhibitory potency of the sodium-calcium exchanger was screened on both cell types by measuring their effect on Ca-45(2+) uptake. Among the most active compounds, N-(2 -amino-5-chloro-4-nitrobenzoyl)-N'-(1-naphtylmethyl)guanidine (IC50 = 3.4 muM) was found more active than amiloride (IC50 = 690 muM) and 3,4-dichlorobenzamil (IC50 = 15.2 muM), the reference inhibitor.
