A large variety of halogenated nitroarenes have been selectively reduced with hydrazine hydrate in the presence of Pd/C to give the corresponding (halogenated) anilines in good yield.

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 45Ca2+ uptake. Among the most active compounds, N-(2-amino-5-chloro-4-nitrobenzoyl)-N′-(1-naphtylmethyl)guanidine (IC50 = 3.4 μM) was found more active than amiloride (IC50 = 690 μM) and 3,4-dichlorobenzamil (IC50 = 15.2 μM), the reference inhibitor.
