Application and Uses
L-5-MTHF-Ca (5-mthf) is a naturally occurring salt-forming methyl derivative of folic acid. 5-mthf is also known as levomethyl-folate, which is the most biologically active and functional of folic acid. Form, more easily absorbed than ordinary folic acid. Common folic acid must be converted to type 1 methyl folate to participate in two major metabolic pathways: methylation and DNA synthesis, the only form of free folate normally present in human plasma and cells is 5-mthf. Lack of folic acid is usually caused by vitamin deficiency, which is insufficient for absorption.
Application:
1. Mainly for folic acid antagonists (such as methotrexate, pyrimethamine, benzyl cefalexin and trimethoprim) antidote, it's usually used for prevention of methotrexate dose or overdose treatment caused severe toxic effects.
2. as adjuvant therapy for colon cancer, rectal cancer
3. Combined with 5-FU and treatment of digestive tract tumors or other 5-FU-sensitive tumors. High-dose CF used in conjunction with 5-FU (LF), the basic programme is currently the treatment of colon and rectal cancer.
