2-Substituted derivatives of the antihistaminic agents Bamipine, Diphenylpyraline and of their 1-phenyl analogues were tested for their antimycobacterial and H(1)-antagonistic activities. They are strong H1-receptor antagonists and also inhibit the growth of mycobacterials with a maximum MIC of 6.25 microg/mL against Mycobacterium tuberculosis H(37)Rv. H1-receptor antagonistic potency was slightly decreased by substitution in ring position 2 and distinctly diminished by N-aryl substitution. The antimycobacterial potency of Diphenylpyraline was in general increased by substitution in ring position 2, whereas only a few Bamipine derivatives showed markedly improved activity. A correlation between the two activities was not detected for those compounds.

A series of compounds containing privileged scaffolds of the known histamine H(1) receptor antagonists cetirizine, mianserin, ketotifen, loratadine, and bamipine were synthesized for further optimization as ligands for the related biogenic amine binding dopamine D(3) receptor. A pharmacological screening was carried out at dopamine D(2) and D(3) receptors. In the preliminary testing various ligands have shown moderate to high affinities for dopamine D(3)receptors, for example, N-(4-{4-[benzyl(phenyl)amino]piperidin-1-yl}butylnaphthalen-2-carboxamide (19a) (hD(3)K(i)=0.3 nM; hD(2)K(i)=703 nM), leading to a selectivity ratio of 2343.

Activity of various amphiphilic agents in reversing multidrug resistance of L 1210 cells

Q1 · MEDICINE

Author: E.W. Hahn ; H. Osswald ; E.W. Pommerenke ; M. Volm

Several compounds (bamipine, chlorphenoxamine, estracyt, hycanthone, quinidine, quinine, tamoxifen, trifluoperazine and verapamil) have a common basic structure with the following features: lipophilic aromatic ring system; linked chain hydrophilic N-alkyl group. They are used medically for varying diseases. Their activity in reversing multidrug-resistance (MDR) with other compounds (diethylstilbestrol, beta-estradiol, methylbiguanide, methylpiperazine, testosterone) lacking one of these chemical features is compared. The in vitro test system we used was the nucleoside incorporation assay using parental L 1210 ascites tumor cells and a doxorubicin resistant subline, which expresses the MDR phenotype. The substances lacking one of these features were not effective in reversing the MDR whereas all other tested substances demonstrated modulating potential in the MDR resistant L 1210 cells.
