  A Bivalent Ligand (KDN-21) Reveals Spinal δ and κ Opioid Receptors Are Organized as Heterodimers That Give Rise to δ₁ and κ₂ Phenotypes. Selective Targeting of δ−κ Heterodimers

  摘要：

  In view of recent pharmacological studies suggesting the existence of delta-kappa opioid receptor heterodimers/oligomers in the spinal cord, we have synthesized and evaluated (intrathecally in mice) a series of bivalent ligands (KDN series) containing kappa and delta antagonist pharmacophores. Pharmacological and binding data have provided evidence for the bridging of spinal delta-kappa receptor heterodimers by KDN-21 and for their identification as delta(1) and kappa(2). The selectivity profile of KDN-21 and the apparent absence of coupled delta(1)-kappa(2) phenotypes in the brain suggest a new approach for targeting receptors.

  Optimum Cross-linking Spacer Length of Dimeric Neurokinin B Analogs for Interaction with NK-1 Tachykinin Receptors.

  摘要：

  为寻找与速激肽受体二价相互作用的最佳连接间隔长度，合成了一系列神经激肽B（NKB）羧基端七肽的二聚体类似物。通过琥珀酰双[甘氨酸（n）—OH]在七肽的氨基端进行二聚化，其中甘氨酸的数目从0到4变化。二聚体D–（甘氨酸）n–NKB4—10，即琥珀酰双[甘氨酸（n）–天冬氨酸–丝氨酸–苯丙氨酸–缬氨酸–甘氨酸–亮氨酸–蛋氨酸–NH2]（n = 0—4），在利用大鼠输精管进行的实验中几乎无活性，表明它们与NK-2受体亚型无相互作用。相比之下，这些二聚体在含有所有NK-1、NK-2和NK-3受体的大鼠回肠（GPI）中非常活跃。当连接间隔为n = 2的寡甘氨酸时，相对活性最高，而链长更短和更长的二聚体（n = 0和1；3和4）活性显著降低。为了明确二聚体在GPI中结合的受体亚型（NK-1或NK-3），在NK-1受体被甲酯化的P物质脱敏的条件下检测了二聚体。所有二聚体的收缩活性都急剧降低，表明二聚体专门与NK-1受体相互作用。进一步通过利用阿托品阻断NK-3受体的反应，证实了这一点，阿托品对二聚体的收缩活性没有影响。结果表明，二聚体通过桥接相邻的两个结合位点与NK-1受体发生二价相互作用。

• Anticandidal activity of 5-fluorocytosine-peptide conjugates

  日期：1979.9

  An approach to the development of new anticandidal drugs is described that employs peptides as carriers of toxic agents into cells. 5-Flurorcytosine (5-FC) was chosen as a toxic agent with which to prepare 5-FC-peptide conjugates as models to test the carrier proposal. Model compounds were synthesized and then tested for antiyeast activity against S. Cerevisiae 9763, C. albicans 1-V, C. albicans WD 18-4, and C. Krusei 1-T. The 5-FC derivatives showed antiyeast activity comparable to 5-FC in all strains except C. krusei 1-T, in which case the compounds were less active. The solution stabilities of 5-FC conjugates at 37 degrees C were tested in the same growth medium used for susceptibility testing. The results indicated a range of stabilities where the half-life (t1/2) = 0.3--17.6 h. These results and those obtained in the susceptibility testing suggest extracellular hydrolysis and indicate that the type of linkage used to conjugate 5-FC to peptides will not provide appropriate compounds to evaluate the peptide-carrier concept.

  A series of dimeric analogs of neurokinin B (NKB) COOH-terminal heptapeptide were synthesized in order to find an optimum length of cross-linking spacer for bivalent interaction with tachykinin receptors. Dimerization was carried out at the NH2-terminus of heptapeptide with succinyl bis[(Gly)n–OH], in which the number of glycine varies from 0 to 4. Dimers D–(Gly)n–NKB4—10, namely succinyl bis[(Gly)n–Asp–Ser–Phe–Val–Gly–Leu–Met–NH2] (n = 0—4), were almost inactive in the assay using rat vas deferens, indicating that they have no interaction with NK-2 receptor subtype. In contrast, these dimers were very active in guinea pig ileum (GPI) containing all of NK-1, 2, and 3 receptors. Relative activity was highest when the cross-linking spacer with oligoglycine of n = 2, and decreased sharply for dimers with shorter and longer chain lengths (n = 0 and 1; 3 and 4). In order to specify receptor subtype (NK-1 or NK-3) in GPI to which dimers bind, dimers were examined under the conditions that NK-1 receptors are desensitized by substance P methyl ester. All dimers exhibited drastically diminished contractile activity, indicating that dimers exclusively interact with NK-1. This was further confirmed by blocking the response of NK-3 receptors with atropine, which had no effect on the contractile activity of dimers. The results suggested that dimers interact bivalently with NK-1 receptors by bridging adjacent two binding sites.
