| Description | Folinic acid (Leucovorin) is a biofolic acid that can be used in the treatment of methotrexate, often in combination with Methotrexate (MTX) to reduce MTX-induced toxicity, and can be used as an adjuvant treatment for colon cancer. |
| In vitro | Methotrexate (MTX) alone induces a concentration-dependent increase in the percentage of micronucleated binucleated cells (MNBN) and abnormal cells (Abs). As the concentration of MTX increases, the nuclear division index (NDI) decreases. Similarly, the mitotic index (MI) also decreases at all tested concentrations of MTX. The addition of 50 μg/mL folinic acid significantly reduces the % MNBN (40-68%) and % Abs (36-77%). In the presence of 5 μg/mL folinic acid, inhibitory effects are observed as well (MNBN from 12% to 54%, Abs from 20% to 61%)[2]. |
| In vivo | 处理小鼠时使用Folinic acid（7.0 mg/kg；腹腔注射；每隔一天；为期3周）似乎能逆转Methotrexate (MTX) 管理在年轻的雄性Balb/c小鼠中引起的生长抑制。众所周知，长期MTX管理会抑制小鼠的骨骼生长[1]。 |
