Webb10 dec. 2007 · Sulfadimethoxine inhibits bacterial synthesis of folic acid (pteroylglutamic acid) from para-aminobenzoic acid. Sulfadimethoxine is approved in Russia for use in humans, including children, and has been successfully used there for more than 35 years. WebbFolic acid (FA) was coupled to nHA with polyethylene glycol (PEG), and the grafting ratio of PEG-nHA and FA-PEG-nHA was determined by the thermogravimetric analysis ...
Delivery luteolin with folacin-modified nanoparticle for glioma …
Sulfamethoxazole, a sulfanilamide, is a structural analog of para-aminobenzoic acid (PABA). They compete with PABA to bind to dihydropteroate synthetase and inhibit conversion of PABA and dihydropteroate diphosphate to dihydrofolic acid, or dihydrofolate. Inhibiting the production of dihydrofolate intermediate interferes with the normal bacterial synthesis of folic acid (folate). Folate is an essential metabolite for bacterial growth and replication because it is used in DNA synthesis, … WebbSince folic acid receptors express on the surface of tumors, we modified the edge of PEG with folic acid, so that luteolin nanodrugs can have targeted function. The content of luteolin in the microparticles was determined by HPLC. The DL and ER of luteolin/Fa-PEG-PCL microparticles were calculated, respectively, by formula (1) and formula (2). english pronunciation for hindi speakers
