تهیّه کیت [I131] متا یُدو بنزیل گوانیدین (MIBG- I131)

Abstract

متا یدوبنزیل گوانیدین به عنوان هم فرمول ”نوراپینفرین“ با اتّصال به یُد رادیوآکتیو به صورت MIBG-I123 و MIBG-I131 به ترتیب برای تشخیص و درمان اختلالات غدّة فوق کلیوی، مانند فئوکروموسیتوما و نوروبلاستوما بکار رفته است. در این کار پژوهشی روشی سریع برای تولید MIBG-I131 عرضه شده است. متایدوبنزیل گوانیدین در مجاورت محلول سولفات مس به I131 اضافه و به مدّت 30 دقیقه در حمام آب جوش قرار گرفت. اساس این کار بر مبنای واکنش جانشینی هسته دوست با حضور یون 1Cu+ و عوامل احیاکنندة کمکی با حرارت دادن محیط واکنش استوار است. برای تنظیم pH و هم‌تنش کردن محلول از بافر سیترات استفاده شد. در این روش، درجة خلوص رادیوشیمیایی بیش از90% بدست آمد. برتری این روش که آن را نسبت به روش‌های دیگر متمایز کرده است سهولت تهیّه و کنترل سریع آن در مراکز پزشکی هسته‌ای است.
