(i)次の式Iの前駆体化合物を[18F]フッ化物イオンの適当な供給源と反応させて次の式IIの化合物を得る段階、
LGは脱離基であり、
PG1はカルボキシ保護基であり、
PG2はアミン保護基である。)
(ii)式IIの化合物をPG1脱保護剤と反応させて次の式IIIの化合物を得る段階、
(iii)式IIIの化合物をPG2脱保護剤と反応させて[18F]FACBCを得る段階、及び
(iv)[18F]FACBCをクエン酸緩衝液で製剤化して医薬組成物を得る段階
を含んでなる方法を提供する。
(i)反応混合物を親水性親油性バランス化(HLB)固相に通すことを含むる第1の精製段階を実施し、
(ii)反応混合物をアルミナ固相に通すことを含む第2の精製段階を任意に含んでいる。
実施例1は、本発明の組成物を得るための方法を記載している。
ATR 減衰全反射率
DTGS 重水素化トリグリシンスルフェート

MeCN アセトニトリル
MeOH メタノール
QMA 第四級メチルアンモニウム
RCY 放射化学収率
SPE 固相抽出
TLC 薄層クロマトグラフィー
UV 紫外線
全ての試薬及び溶媒はMerck社から購入し、それ以上精製せずに使用した。[18F]FACBC前駆体であるsyn−1−(N−(tert−ブトキシカルボニル)アミノ)−3−[[(トリフルオロメチル)スルホニル]オキシ]シクロブタン−1−カルボン酸エチルエステルは、GE Healthcare社から入手した。Oasis HLB plusカートリッジ及びSep−Pakカートリッジ(QMA light Plus(K2CO3形)、tC18 light、Alumina N light)は、Waters社(ミルフォード、米国マサチューセッツ州)から購入した。全ての放射能測定のためにCapintec Nalイオンチャンバー(モデルCRC15R)を使用した。ラジオ薄層クロマトグラフィー(ラジオTLC)は、シリカゲルの予備被覆プレート(Merck 60F254)を用いてPackardインスタントイメージャー上で実施した。
実施例1:本発明の[ 18 F]FACBC組成物の合成及び製剤化
GE PETtrace 6サイクロトロン(Norwegian Cyclotron Centre、オスロ)上での18O(p,n)18F核反応によって担体無添加[18F]フッ化物イオンを生成した。デュアルビームの30μA電流を使用しながら、HAVAR箔を備えた2つの同等なAgターゲットに16.5MeVのプロトンを用いて照射を行った。各ターゲットは、96%以上の[18O]水(Marshall Isotopes社)を1.6ml含んでいた。照射及びホットセルへの送達に続いて、各ターゲットを1.6mlの[16O]水(Merck社、GR分析用の水)で洗浄し、3.2mlの[16O]水中に約2〜5Gbqを得た。
