Over 60% of currently used anti-cancer agents are derived in one-way or another from natural sources, including plants, marine organisms and microorganisms. Calotropis gigantea (Linn.) (Family: Asclepiadaceae) is a perennial shrub and it is used as a traditional folk medicine for the treatment of various health complications. But there is no report on isolation of anticancerous chemicals from the flower of Calotropis gigantea. The objective of the present study is to explore the antitumor effect of anhydrosophoradiol-3-acetate (A3A), isolated from the flower of Calotropis gigantea (Linn.) against Ehrlich's ascites carcinoma (EAC) in Swiss albino mice.
Antitumoric effect of A3A was assessed by evaluating viable tumor cell count, survival time, body weight gain due to tumor burden, hematological and biochemical (glucose, cholesterol, triglyceride, blood urea, SALP, SGPT and SGOT) parameters of EAC bearing host at doses of 10 and 20 mg/kg body weight.
Treatment with A3A decreased the viable tumor cells and body weight gain thereby increasing the life span of EAC bearing mice. A3A also brought back the altered hematological (Hb, total RBC and total WBC) and biochemical parameters more or less to normal level.
Results of this study conclude that in vivo the A3A was effective in inhibiting the growth of EAC with improving in cancer induced complications.
目前使用的 60%以上的抗癌药物都或多或少地来源于天然来源,包括植物、海洋生物和微生物。牛奶菜(Calotropis gigantea(Linn.)(家族:夹竹桃科)是一种多年生灌木,它被用作治疗各种健康并发症的传统民间药物。但是,目前还没有从牛奶菜的花中分离出抗癌化学物质的报道。本研究的目的是探索从牛奶菜(Calotropis gigantea(Linn.))花中分离得到的脱水螺旋内酯醇-3-乙酸酯(A3A)对瑞士白化病小鼠艾氏腹水癌(EAC)的抗肿瘤作用。
通过评估活肿瘤细胞计数、存活时间、因肿瘤负担导致的体重增加、EAC 荷瘤宿主的血液学和生化(葡萄糖、胆固醇、甘油三酯、血尿素、SALP、SGPT 和 SGOT)参数来评估 A3A 的抗肿瘤作用。以 10 和 20mg/kg 体重的剂量。
A3A 治疗可减少活肿瘤细胞并增加体重增加,从而延长 EAC 荷瘤小鼠的寿命。A3A 还使改变的血液学(Hb、总 RBC 和总 WBC)和生化参数或多或少恢复到正常水平。
这项研究的结果表明,在体内,A3A 有效抑制 EAC 的生长,并改善癌症引起的并发症。
