Phytol (Pyt), a diterpenoid, possesses many important bioactivities. This study evaluates the anticancer effects of Pyt on sarcoma 180 (S-180) and human leukemia (HL-60) cell lines. For this purpose, cells were treated with Pyt (4.72, 7.08, or 14.16 μM) and a cell viability assay was performed. Additionally, the alkaline comet assay and micronucleus test with cytokinesis were also performed using doxorubicin (6 μM) and hydrogen peroxide (10 mM) as positive controls and stressors, respectively. Results revealed that Pyt significantly reduced the viability and rate of division in S-180 and HL-60 cells with IC values of 18.98 ± 3.79 and 1.17 ± 0.34 μM, respectively. Pyt at 14.16 μM exerted aneugenic and/or clastogenic effects in S-180 and HL-60 cells, where the number of micronuclei and other nuclear abnormalities (e.g., nucleoplasmic bridges and nuclear buds) were frequently observed. Moreover, Pyt at all concentrations induced apoptosis and showed necrosis at 14.16 μM, suggesting its anticancer effects on the tested cancer cell lines. Taken together, Pyt showed promising anticancer effects, possibly through inducing apoptosis and necrosis mechanisms, and it exerted aneugenic and/or clastogenic effects on the S-180 and HL-60 cell lines.
植物醇(Pyt)是一种二萜类化合物,具有许多重要的生物活性。本研究评估了 Pyt 对肉瘤 180(S-180)和人白血病(HL-60)细胞系的抗癌作用。为此,用 Pyt(4.72、7.08 或 14.16 μM)处理细胞,并进行细胞活力测定。此外,还使用阿霉素(6 μM)和过氧化氢(10 mM)作为阳性对照和应激源,分别进行碱性彗星试验和有丝分裂微核试验。结果表明,Pyt 显著降低 S-180 和 HL-60 细胞的活力和分裂率,IC 值分别为 18.98±3.79 和 1.17±0.34 μM。Pyt 在 14.16 μM 时对 S-180 和 HL-60 细胞产生了变应原性和/或断裂剂效应,经常观察到微核和其他核异常(如核质桥和核芽)的数量增加。此外,Pyt 在所有浓度下诱导细胞凋亡,并在 14.16 μM 时显示出坏死,表明其对测试的癌细胞系具有抗癌作用。综上所述,Pyt 表现出有希望的抗癌作用,可能通过诱导细胞凋亡和坏死机制,并对 S-180 和 HL-60 细胞系产生变应原性和/或断裂剂效应。
