被験組成物57~392をそれぞれ4℃に1本、60℃の安定性試験器に4本保存した。各4℃保存品を開始時、各60℃保存品を1週間ごとに取り出し、逆相HPLCにより含量を算出し、保存開始時の含量に対する含量割合(%)の減少による安定性の評価を行った。
各被験組成物の開始時を検量線試料(100%)として、実施例1-2と同様の方法で検量線試料(60%~100%)を調製した。検量線試料(60%~100%)及び各保存試料につき30 μLを実施例1-2と同様の方法でHPLCにて測定した。
結果を図17~23に示す。本結果より、PK-7006、NK-7006及びPH-7069は、60℃、4週間でも高い保存安定性を有することが示された。
本出願は、日本で出願された特願2014-267087(出願日:2014年12月29日)及び特願2015-081298(出願日:2015年4月10日)を基礎としており、その内容は全て本明細書に包含されるものとする。
