  • 2-Alkyl-substituted histamines and hydroxyethylimidazoles with G-protein-stimulatory activity
    作者:H Detert、C Leschke、W Tögel、R Seifert、W Schunacki
    DOI:10.1016/0223-5234(96)89166-5
    日期:1996.1
    Cationic-amphiphilic 2-substituted histamines activate pertussis toxin-sensitive guanine nucleotide-binding proteins (G-proteins) by a receptor-independent mechanism. From our recent studies it became apparent that lipophilicity is an important determinant for this G-protein activation, but the influence of basicity remained unknown. We prepared seven novel 2-alkyl-substituted histamines and five novel 2-alkyl-substituted hydroxyethylimidazoles and studied their effects on high-affinity guanosine triphosphate (GTP) hydrolysis in membranes of the human leukemia cell line, HL-60. 2-Octylhistamine was found to be the most effective GTPase activator among 2-substituted histamines presently available (150% stimulation above basal), and 2-tetradecylhistamine is the most potent substance in this regard (pEC(50) = 5.9). Branching of the alkyl chain and the introduction of an ether group adversely affected GTPase activation. Compared to a phenyl ring, a bulky adamantyl sphere enhanced G-protein-stimulatory activity. In the case of 2-(3-bromophenyl)histamine, 2-adamantylhistamine and 2-(3-phenylpropyl)histamine, replacement of the aminoethyl group by a hydroxyethyl group at the imidazole greatly reduced GTPase-activating properties, pointing to the importance of the basic domain in the activation process. Unexpectedly, however, in the case of a very lipophilic substituent (heptadecyl chain) the exchange of the aminoethyl group by a hydroxyethyl group had no substantial inhibitory effect, indicating that the presence of a primary amine is not a conditio sine qua non for a substance being a receptor-independent G-protein activator. Concerning histamine H-1-receptors the newly prepared compounds proved to be weak antagonists.
