  • Silver carboxylate promoted lactonization: a general method applicable to prepare medium and large-sized lactones without high dilution or slow addition
    作者:Le Liu、Shimin Xu、Hongwei Zhou

    日期:2013.9
    and simple operation, remains a challenging task for the organic community. We developed a ‘freshman-can-do’ protocol to medium- and large-sized lactones, not depending on high-dilution or slow addition techniques. Application of this method for the synthesis of natural lactones or potentially pharmaceutical compounds might be useful for organic chemists and pharmacists.

  • Effects of adenine nucleosides and nucleotides on neuromuscular transmission to the prostatic stroma of the rat

    The aim of this study was to investigate the effects of adenine nucleosides and nucleotides on contractility of the smooth muscle of rat prostate gland. Nerve terminals within rat isolated prostatic tissues were electrically field stimulated (60 V, 0.5 ms, 10 Hz, 20 pulses every 60 s). Adenosine 5′‐triphosphate (ATP), adenosine 5′‐diphosphate (ADP), adenosine 5′‐monophosphate (AMP) and adenosine had no effect on baseline smooth muscle tone but concentration‐dependently inhibited electrically‐evoked contractile responses. The relative order of potency was ATP ≅ AMP ≅ adenosine>ADP. The inhibition by ATP and adenosine of field stimulation‐induced contractions in the rat prostate was antagonized by 8‐phenyltheophylline (10 μM), but not by suramin (100 μM) and only slightly by reactive blue 2 (5 μM). The adenosine metabolizing enzyme adenosine deaminase (0.1 unit ml−1) inhibited the inhibitory effects of ATP and adenosine. The P2 purinoceptor agonist 2‐methylthio ATP (10 nM–0.1 mM), had no effect on field stimulation‐induced contractions of the rat prostate. ATP and adenosine did not modify the contractile responses of the rat prostate to exogenously added noradrenaline (10 μM). Inhibitory concentration‐response curves to a number of adenosine analogues with differing stabilities and selectivities for the different adenosine receptors yielded a relative rank order of agonist potency of: N6‐cyclopentyladenosine (CPA)>N6‐cyclohexyladenosine (CHA) ≅ (−)‐N6‐(2‐phenylisopropyl)‐adenosine (R‐PIA) ≅ 5′‐(N‐ethylcarboxamido)‐adenosine (NECA)>(+)‐N6‐(2‐phenylisopropyl)‐adenosine (S‐PIA)>2‐p‐[2‐carboxyethyl]phenethyl‐amino‐5′‐N‐ethylcarboxamido‐adenosine (CGS 21680). These results indicate that adenine nucleoside and nucleotide induced inhibition of electrically‐evoked contractions in the rat prostate occurs through activation of adenosine but not ATP receptors. The relative order of potency of adenosine analogues is consistent with activation of receptors of the A1‐adenosine receptor subtype. These receptors appear to be prejunctional.

    本研究的目的是探讨腺嘌呤核苷和核苷酸对大鼠前列腺平滑肌收缩的影响。 在大鼠前列腺组织中,神经末梢被电场刺激(60 伏,0.5 毫秒,10 赫兹,每 60 秒 20 次脉冲)。ATPADPAMP腺苷对基线平滑肌张力没有影响,但浓度依赖性地抑制了电刺激引起的收缩反应。效力的相对顺序为 ATPAMP腺苷 > ADP ATP腺苷对大鼠前列腺电刺激引起的收缩的抑制作用被 8-苯基茶碱(10 μM)拮抗,但不被 suramin(100 μM)拮抗,仅轻度被 reactive blue 2(5 μM)拮抗。 腺苷代谢酶腺苷脱氨酶(0.1 单位/毫升)抑制了 ATP腺苷的抑制作用。P2 突触前受体激动剂 2-甲ATP(10 nM–0.1 mM)对大鼠前列腺电刺激引起的收缩无影响。 ATP腺苷不会改变大鼠前列腺对外源性添加的去甲肾上腺素(10 μM)的收缩反应。 针对稳定性不同的多种腺苷类似物的抑制浓度反应曲线,产生了激动剂效力的相对排序:N⁶-环戊基腺苷(CPA)> N⁶-环己基腺苷(CHA) ≅ (-)-N⁶-(2-苯基异丙基)腺苷(R-PIA) ≅ 5′-(N-乙基羧酰胺)腺苷(NECA)> (+)-N⁶-(2-苯基异丙基)腺苷(S-PIA)> 2-p-[2-羧乙基]苯乙基基-5′-N-乙基羧酰胺腺苷(CGS 21680)。 这些结果表明,腺嘌呤核苷和核苷酸引起的对大鼠前列腺电刺激收缩的抑制是通过激活腺苷受体而非 ATP 受体实现的。腺苷类似物效力的相对顺序与激活 A₁-腺苷受体亚型一致。这些受体似乎位于前突触。 British Journal of Pharmacology (2000) 131, 1073–1080; doi: 10.1038/sj.bjp.0703652
