General description

Chemical structure: nucleoside
Formycin A is an adenosine analog, and is cytotoxic in nature. It acts as a substrate for the human enzymes human erythrocytic adenosine deaminase and adenosine kinase.

Biochem/physiol Actions

Formycin A (FA) is a C-nucleoside that inhibits the E.coli enzyme purine nucleoside phosphorylase (PNP). FA was found to upsurge insulin release elevated by glucose, and was also shown to inhibit 5′-Methylthioadenosine/S-adenosylhomocysteine (MTA/AdoHcy) nucleosidase, an enzyme important in the recycling of methionine. Research has shown FA is an antiretroviral agent against HIV-1, targeting reverse transcription.
Formycin A possess antitumor function, along with its antibacterial and antiviral activity.

5'-Methylthioadenosine/S-adenosylhomocysteine (MTA/AdoHcy) nucleosidase is a key enzyme in a number of critical biological processes in many microbes. This nucleosidase catalyzes the irreversible hydrolysis of the N(9)-C(1') bond of MTA or AdoHcy to form adenine and the corresponding thioribose. The key

Formycin A (FOR-A) and pyrazofurin A (PRF-A) are purine-related C-nucleoside antibiotics in which ribose and a pyrazole-derived base are linked by a C-glycosidic bond. However, the logic underlying the biosynthesis of these molecules has remained largely unexplored. Here, we report
