Cinobufotalinは、複数の生物学的活性を持つステロイドグリコシドである[1]。Cinobufotalinはヒキガエルの分泌物から抽出される心態式ステロイドである[2]。Cinobufotalinは心態、利尿薬、止血薬として使用されており、抗腫瘍活性も患っている[3]。
体外では、Cinobufotalin(0.1、1、5、10μM)の治療は24-72時間で用量依存的にSK-OV-3、CRL-1978とCRL-11731細胞の増殖、遷移と浸潤を阻害する[4]。 Cinobufotalin(40、60、80nm)の24-48Hの治療はHEPG2、SMMC-7721とSNU-368細胞に作用し、上皮マーカー(E-Cadherin)を上方修正し、間葉系マーカー(N-Cadherin,Snail,Snail,Snail,Slug和Zeb1和Zeb1)を下方修正する[5]。
体内ではCinobufotalin(1,5mg/kg)で1週間腹腔内注射によりA549細胞異種移植鼠を治療に与え、それは腫瘍の成長率を著しく阻害し、生存率を増加できる[6]。 Cinobufotalin(5mg/kg)は復興内注射によってH22肝がん鼠を治療することで顕著に腫瘍の成長を阻害し、鼠の免疫機能を増加し、Cinobufotalinの化学療法作用を高める[7]。
