多くのグリコスフィンゴ脂質を合成し、NKT細胞活性についてテストした。化合物の構造は式1によるものである。
<抗原提示細胞(APC)の活性>
A20CD1d細胞及びmNK1.2細胞を、APC及び効果細胞としてそれぞれ使用した。Guava ViaCount試薬を、Guava EasyCyte Plusを備える細胞の生存能力及び生存可能数を決定するために使用した。マウスIL−2 DuoSet ELISA Development Systemを、IL−2の生産を検知するために使用した。細胞及び糖脂質を37℃で共培養し、培養の24時間後に上清を、収集した。そして、培養の2日後に、生存可能性を決定するために細胞を回収し、その結果は、これらのグリコスフィンゴ脂質(glycospingolipids)が有毒でないことを示す。図6に示されるように、この組み合わせにおいて、試験化合物はすべて、APC活性活動を示す。
メスのC57BL/6マウス(16w4d)を犠牲にし、脾臓をアッセイのために回収した。細胞及び糖脂質を、3日間、37℃で共培養し、培養の後3日後(〜60時間)に上清を収集した。その後、アラマーブルー(alarma Blue)(5%/200ul)を加え、細胞増殖を決定するために、細胞を7時間、培養した。マウスIL−4及びIFN−γ Duo Set ELISA Development Systemを、サイトカインの生産を検知するために使用した。このアッセイでは、DMSOは、負の対照であって、KRN−7000は正の対照であった。図7−9に示されるように、化合物は、Th1に偏ったサイトカイン分泌特性を示し、抗腫瘍性、抗ウイルス性/抗菌性、及びアジュバントの活性へのそれらの適用可能性を示す。
