  Novel hypotensive agents from Verbesina caracasana. 2. Synthesis and pharmacology of caracasanamide

  摘要：

  Caracasanamide, one of the hypotensive agents isolated from Verbesina caracasana, is a mixture of (Z)-1a and (E)-lb forms of 1-[(3,4-dimethoxycinnamoyl)amino]-4-[(3-methyl-2-butenyl)-guanidino]butane.1 The structure of (E)-caracasanamide (1b) was confirmed by high-yielding synthesis starting from N,N'-bis(tert-butoxycarbonyl)-S-methylisothiourea. The water-soluble Z-form of 1a, assayed by iv route in anesthetized rats at doses ranging from 50 to 1600 mug/kg body weight, was found to decrease blood pressure, to increase cardiac inotropism, respiratory frequency, and tidal volume, and to induce a very slight and not significant tachycardia. Higher doses determined respiratory depression and, in some cases, consequent cardiac arrest. The compound was shown to affect cardiovascular function by acting at the vascular level in inducing arterial vasodilation, by determining sympathetic hypotone through central neurogenic mechanisms, and by interacting with the cardiac beta1-adrenoreceptors. The respiratory effects were independent of the cardiovascular ones. In lowering blood pressure, the compound was more potent than guanethidine and not less potent than reserpine and papaverine. (Z)-Caracasanamide may therefore be useful in the treatment of arterial hypertension of moderate degree.

  Caracasancliamide, a second hypotensive agent isolated from Verbesina caracasana, is the cyclobutane dimer (truxinic type) of the previously reported 1-[(3,4-dimethoxycinnamoyl)amino]-4-[(3-methyl-2-butenyl)guanidino]butane (caracasanamide) (Delle Monache, G.; et al. BioMed. Chem. Lett. 1992, 25, 415-418). The structure was confirmed by synthesis starting from beta-truxinic acid obtained by photoaddition of 3,4-dimethoxycinnamic acid. The dimer was coupled with 2 mol of prenylagmatine to give caracasandiamide in satisfactory yield. By contrast, the direct photodimerization of caracasanamide was unsuccessful. Caracasandiamide, assayed by the iv route in anesthetized rats at doses ranging from 50 to 3200 mu g/kg of body weight, was found to have! no appreciable effect on heart rate. At lower doses, the drug stimulates breathing and increases cardiac inotropism, stroke volume, and cardiac output, thus augmenting blood pressure and aortic flow. At higher doses, caracasandiamide depresses breathing likely through central neurogenic mechanisms (not involved in the cardiovascular effects), continues to stimulate cardiac inotropism, and induces, by reducing peripheral vascular resistance, arterial hypotension with reduction of both aortic flow and stroke volume. These cardiovascular effects appear to involve complex interactions at the level of the peripheral beta(1)-, beta(2)-, and alpha(2)-adrenoreceptor-dependent as well as M-2- and M-4-cholinergic receptor-dependent transductional pathways both in cardiovascular myocells and at the level of the postganglionic sympathetic endings (with reserpine- and guanethidine-like mechanisms). The cardiovascular effects of caracasandiamide, different from those of caracasanamide, do not depend, on significant actions on the central nervous system and on baroreflex path-ways. In a similar manner and more effective than caracasanamide, caracasandiamide may be considered a hypotensive and antihypertensive drug. It is devoid of some of the negative side effects, e.g., reflex tachycardia and decreased cardiac inotropism, which are shown by the majority of the most common antihypertensive and vasodilator drugs.

  Previous studies on agmatine and its derivatives suggested that the presence of hydrophobic groups on the guanidine moiety was a crucial key for inhibitory activity of maize polyamine oxidase. Accordingly, new lipophilic agmatine and iminoctadine derivatives were synthesized and tested for their ability to inhibit this enzyme. Several compounds showed an affinity in the nanomolar range, while a cyclopropylmethyl derivative of iminoctadine was found to be the most potent inhibitor of maize polyamine oxidase reported so far (K-i = 0.08 nM).
