(1)変異体の製造及び培養条件
Ban、YH外(非特許文献16)に記載された方法に基づいてFK506を生産する菌株であるストレプトマイセス属KCTC11604BPのfkbD 遺伝子を二重交差相同組換え(double cross-over homologous recombination)によるインフレーム(inframe)欠失を通じて非活性化して△fkbDin−frame菌株を製造した。
上記△fkbDin−frame菌株の培養液4Lを遠心分離し、上澄液を酢酸エチルを用いて2回溶媒−溶媒分配(solvent-solvent partition)した。酢酸エチルに溶解した層を分離し、減圧下で蒸発させて暗赤色の抽出物を得た。上記抽出物を流速2mL/minにし、移動相としては60%の水性メタノールを使用し、逆相分取クロマトグラフィー(preparative reversed-phase HPLC)により分画してHPLC−ESI−MS分析を行った。
光学回転は、0.1dm経路の長さのセルを利用してJasco P−1010 polarimeterで測定した。
上記非定型の白色固体の分析結果は、下記の通りである。
図1は、△fkbDin−frame菌株の培養抽出物のHPLC−ESI−MS分析の結果として、m/z 793.1、13分とm/z 807.1、28分でアンモニウム付加物イオンのピークが現れた。したがって、図2で示された776.1、758.1、740.1、547.9で示されたフラグメントイオン(fragment ion)を見たときに、m/z 793.1、13分で示されるピークは9−デオキソ−プロリル−FK506によるものと予測した。各フラグメントイオン間の間隔が14Daであるという点で9−デオキソ−プロリル−FK506のフラグメントパターンは、9−デオキソ−FK506と類似する。しかし、9−デオキソ−FK506で特有のC−1−C−24フラグメントイオンは、m/z 561.9で示されたのに対し、本発明の9−デオキソ−プロリル−FK506の場合、m/z 547.9で示された。これは、9−デオキソ−プロリル−FK506が9−デオキソ−FK506及び他の9−デオキソ−FK506誘導体に比べて特有のC−1−C−24フラグメントでメチレン基を1個少なく有していることを示唆するものである。
上記非定型の白色固体に対してHR−ESI−MS分析した結果、m/z 776.4940で[M+H]+イオンを得、これは分子式であるC43H70NO11(calcd m/z 776.4949)と一致するように明らかになった。

(1)イン・ビトロ(In vitro)T−細胞活性分析
実際に、FK506と比較した上記化合物9−デオキソ−プロリル−FK506の相対的な免疫抑制特性は、Tリンパ球(lymphocytes)を使用してMo、SJ外(非特許文献17)に記載された方法で決定した。簡略的に、CD3/CD28−活性化したヒトT−細胞に上記化合物を0.1nMの濃度で16〜20時間処理した後、インターロイキン−2の分泌量を定量した。
FK506と比較した上記化合物の相対的な神経再生活性は、ラットPC12細胞(pheochromocytoma cell)を利用して、Mo、SJ外(非特許文献17)に記載の方法で決定した。上記PC12細胞に神経突起増殖を誘導する神経成長因子(NGF; KOMA Biotech; 10 ng/ml)を96時間処理した。このとき、10nM FK506または9−デオキソ−プロリル−FK506を共に処理または除外した。神経突起の長さは、プリントされた写真を使用してRevill、WP外(非特許文献18)に記載された方法で測定した。
