A series of trichloroacetamidine derivatives, obtained by addition of amines to trichloroacetonitrile, was evaluated for positive inotropic activity on isolated cat heart papillary muscles. Increased contractility, not antagonized by beta-adrenergic blockade with sotalol or reserpine pretreatment, was observed in this assay with a variety of N-substituted trichloroacetamidine derivatives. More extensive pharmacological studies with the 3-indolylmethyl analogue 2 showed that this amidine in dogs, 5 mg/kg iv, produced a positive inotropic effect more pronounced than that of ouabain, 50 microgram/kg iv. Several of the trichloroacetamidines were found to be inhibitors of guinea pig kidney and calf heart Na-K-dependent ATPase and to have specificity for these enzymes different from that of ouabain. Bacterial mutagenic activity was observed with three members, 2,3, and 12, of the series.

A mild platinum-catalysed method for the formation of free amidines from the reaction of amines and trichloroacetonitrile in nonpolar solvents has been developed. This protocol provides access to novel amidines that in some cases (4b–d) cannot be synthesised via the direct reaction of amines and halogenated nitriles.

Iodocyclisation of allyl-amidines (1) and-ureas (4) gives imidazolines (2) and imidazolinones (5) respectively; in contrast, bromocyclisation of the amidine (1a) results in formation of the six-membered ring (3).
