Biological Activity

Folinic acid is an adjuvant used in cancer chemotherapy involving the compound methotrexate. Folinic acid serves as a cofactor and participates in one-carbon-transfer reactions. It helps in improving wound healing in rats. Folinic acid calcium salt has been used in the preparation of topical 1% and 2.5% folinic acid creams for use in wound healing studies. It has also been used as a component in the chemically defined-Chinese hamster ovary medium (CD-CHO) to culture CHO DUKX B11.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
