    derivatives was synthesized as dual inhibitors of thromboxane A(2) synthase (P450 TxA(2)) and aromatase (P450 arom). Dual inhibition of these enzymes could be a novel strategy for the treatment of mammary tumors and the prophylaxis of metastases. The most potent dual inhibitors, 5-(2-imidazol-1-ylethyl)-7,8-dihydroquinoline (31) (P450 TxA(2): IC(50) = 0.29 microM; P450 arom: IC(50) = 0.50 microM) and its

  • New combination of pharmacophoric elements of potent σ1 ligands: Design, synthesis and σ receptor affinity of aminoethyl substituted tetrahydrobenzothiophenes
    作者:Dipak Harel、Dirk Schepmann、Bernhard Wünsch
    DOI:10.1016/j.ejmech.2013.09.006
    日期:2013.11
    The aminoethyl substituted tetrahydrobenzothiophenes 4 resulted from combination of the pharmacophoric elements of the potent cri ligands 2 and 3. The aminoethyl substituted tetrahydrobenzothiophenes 4 were prepared in an 8-step synthesis starting with thiophene. Whereas the rri affinity of the N-benzyl derivative 4a is in the medium nanomolar range (K-i = 49 nM), the analogous N-cyclohexylmethyl derivative 4d exhibits low nanomolar affinity (Ki = 5.0 nM). The reduced sigma(1) affinity and sigma(2)/sigma(1) selectivity of tetrahydrobenzothiophenes 4 compared to analogous spirocyclic piperidines 3 is attributed to the increased conformational flexibility of the aminoethyl side chain.
