  • Specific Affinity Labeling of<i>μ</i>Opioid Receptors by S-Activated Enkephalin Analog Containing<i>p</i>-Nitrophenylalanine

    p-Nitrophenylalanine (Phe(p-NO2)) was incorporated in place of Phe4 of [d-Ala2, Leu(CH2S-Npys)5]enkephalin. In the rat brain receptor binding assay, Npys-containing Phe(p-NO2)4- and Phe4-enkephalins exhibited almost unchanged affinities for μ receptors (IC50 = 16—21 nM). However, when the membrane was incubated with each analog, Phe(p-NO2)4-enkephalin (EC50 = 6.90 nM) could label the μ receptors about three times more effectively than Phe4-enkephalin.
    硝基苯酸(Phe(p-NO2))取代了[d-Ala2, Leu(CH2S-Npys)5]脑啡肽的Phe4。在大鼠脑受体结合实验中,含Npys的Phe(p- )4-和Phe4-脑啡肽对μ受体的亲和力几乎不变(IC50 = 16—21 nM)。然而,当膜与每个类似物孵育时,Phe(p- )4-脑啡肽EC50 = 6.90 nM)标记μ受体的效率比Phe4-脑啡肽高约三倍。
  • Synthesis of sulfur-containing analogs of bestatin. Inhibition of aminopeptidases by .alpha.-thiolbestatin analogs
    作者:Timothy D. Ocain、Daniel H. Rich
    DOI:10.1021/jm00119a022
    日期:1988.11
    Sulfur-containing amino acid and peptide analogues of bestatin [((2S,3R)-3-amino-2-hydroxy-4-phenyl-butanoyl)-L-leucine] (1) have been synthesized and evaluated as inhibitors of aminopeptidase M (AP-M), leucine aminopeptidase (LAP), and aminopeptidase B (AP-B). The 2-thiolbestatin analogue (6) was found to be a potent inhibitor of all three aminopeptidases (AP-M, Ki = 4.4 microM; LAP, Ki = 0.55 microM; AP-B, Ki = 4.6 nM) but only a slightly better inhibitor of these aminopeptidases than the parent hydroxy-containing compound 1. Synthetic analogues of L-leucinethiol(4), a strong inhibitor of aminopeptidases, were prepared in which the carbon alpha to the thiol groups was substituted with methyl, methyl carboxylate, and carboxamide derivatives and found to be much weaker inhibitors of all aminopeptidases. A thioamide analogue of bestatin (49) is a modest inhibitor of AP-M (Ki = 40 microM), LAP (Ki = 0.33 microM), and AP-B (Ki = 2.4 microM). These results suggest that the sulfur atoms in 2-thiolbestatin and bestatin thioamide do not interact strongly with the active-site zinc atom of these aminopeptidases when the inhibitors are bound to the enzyme. These results are not consistent with proposed models for the inhibition of aminopeptidases by bestatin and related analogues.
