    摘要:
    为了确定放射性碘化碲脂肪酸的心肌摄取和保留特性,我们制备了两种新的碲脂肪酸,其中碘125已通过附着作为反乙烯基碘而化学稳定(I-CH = CH-R-Te-R '-COOH),并在大鼠中对其进行了评估。通过将1,5-二碘-1-戊烯与12-(甲氧基羰基)-n-十二烷基-1-基碲化钠偶联来完成18-碘-13-碲-十七-十八烯酸的制备。[5-125I] -1,5-二碘-1-戊烯是通过有机硼烷技术制备的,该技术涉及125I +处理5-碘-1-戊-1-基硼酸[I(CH2)3CH = CHB(OH)2 ]。该药物的绝对心脏摄取量中等(60分钟后为1.47-2.52%剂量/克),但心脏/血液比率较低(约2.6:1)。仅发生体内边缘脱碘,因为甲状腺摄取量低(60分钟后剂量为15-18%/ g)。碲在位置13的影响是出乎意料的。为了确定低心脏特异性和低心/血比是否取决于碲的位置,我们制备了具有相同链长的类似物18-

    日期:——
    Functionalized arylmagnesium reagents bearing an ester, cyano, nonaflate or trialkylsilyloxy group undergo fast cross-coupling reactions with alkenyl iodides or bromides in the presence of catalytic amounts of Fe(acac)3 (5 mol%) at -20 °C within 1 hour resulting in the formation of the desired cross-coupling products in satisfactory yields. Excellent yields can be achieved by performing the cross-coupling reaction on solid phase by generating the Grignard reagent on the resin.

  • Effects of alkyl and aryl substitution on the myocardial specificity of radioiodinated phosphonium, arsonium, and ammonium cations
    作者:P. C. Srivastava、H. G. Hay、F. F. Knapp
    DOI:10.1021/jm00145a009
    日期:1985.7
    Several radioiodinated iodopentenyl-trisubstituted phosphonium, arsonium, and ammonium iodides have been prepared and evaluated in rats to determine the effects of structural variations of the cations on myocardial uptake and retention. The synthesis of (E)-(1-iodo-1-penten-5-yl)-trisubstituted phosphonium, arsonium, and ammonium iodides via the condensation of trisubstituted phosphine, arsine, and amine precursors, respectively, with (E)-1,5-diiodopentene is described. In some cases a second route involved condensation with (E)-1-borono-5-iodo-1-pentene followed by iodination. In the phosphonium series, the compounds triphenyl 1, dicyclohexylphenyl 5, tricyclohexyl 6, and dimethyl-n-octyl 8 were prepared. The triphenylarsonium 10 and triethylammonium 11 compounds were also prepared. The corresponding radioiodinated analogues were prepared and tissue distribution studies performed in rats. The results (percent dose/gram, 30 min) demonstrate that replacement of phosphorus with arsenic (1, 3.99%; 10, 3.17%) or the replacement of the phenyl ring with the cyclohexyl ring system (6, 2.67%) has no apparent effect on heart uptake. In the series of compounds studied, replacement of the cyclic ring system with alkyl groups, however, significantly decreased heart uptake with both the phosphorus (8, 1.95%) and nitrogen agents (11, 1.11%). Gamma camera imaging studies with [123I]-5 and [123I]-8 further substantiated the decreased heart uptake with alkyl substitution and the apparent hepatobiliary clearance of 8.
