ALL living cell need tetrahydrofolate cofactor for the synthesis of ........ purines, some amino acid and thymidine. Most bacteria and plant produce this folate cofactor by de novo biosynthesis. Compounds that interfere with this pathway, antifolate agents have found use as anticancer. Thus, the 2-propyl-4H-3,1-benzoxazin-4-one (2) was synthesized and allowed to interaction with Ammonium acetate o...
