Biochem/physiol Actions

6-Hydroxy-DL-DOPA is an inhibitor of APE1 (apurinic/apyrimidinic endonuclease) repair-function activity. APE1 is a nuclease crucial for DNA base excision repair pathway. 6-Hydroxy-DL-DOPA also blocks RAD52 (DNA repair protein) single-stranded DNA binding domain.
Precursor of the catecholaminergic neurotoxin, 6-hydroxydopamine; converted to 6-hydroxydopamine by L-aromatic amino acid decarboxylase.

Suppression of RAD52 causes synthetic lethality in BRCA-deficient cells. Yet pharmacological inhibition of RAD52, which binds single-strand DNA (ssDNA) and lacks enzymatic activity, has not been demonstrated. Here, we identify the small molecule 6-hydroxy-DL-dopa (6-OH-dopa) as a major allosteric inhibitor

2,4,5-Trihydroxyphenylalanine (TOPA) oxidizes in solution to form a quinone derivative that is a non-NMDA glutamatergic agonist and neurotoxin. DOPA can autoxidize in physiological solutions to form small amounts of both TOPA and TOPA quinone. We report here that this conversion

Although several nucleo(s)tide analogs are available for treatment of HBV infection, long-term treatment with these drugs can lead to the emergence of drug-resistant viruses. Recent HIV-1 studies suggest that combination therapies using nucleo(s)tide reverse transcriptase inhibitors (NRTIs) and non-nucleo(s)tide reverse
