The present invention is directed to methods and compositions for activating a Parkin ligase by administering to a subject in need thereof a therapeutically effective amount of a compound that disrupts at least one Parkin ligase zinc finger. The present invention is also directed to methods of treating and/or reducing the incidence of diseases or conditions related to the activation of Parkin ligase.

We previously identified two small molecules targeting the HIV-1 gp41, N-(4-carboxy-3-hydroxy)phenyl-2,5-dimethylpyrrole 12 (NB-2) and N-(3-carboxy-4-chloro)phenylpyrrole 13 (NB-64), that inhibit HIV-1 infection at low micromolar levels. Oil the basis of molecular docking analysis, we designed a series of 2-aryl 5-(4-oxo-3-phenethyl-2-thioxothiazolidinylidenemethyl)furans. Compared with 12 and 13, these compounds have bigger molecular size (437-515 Da) and could occupy more space in the deep hydrophobic pocket oil the gp41 NHR trimer. Fifteen 2-aryl 5-(4-oxo-3-phenethyl-2-thioxothiazolidinylidenemethyl)furans (11a-o) were synthesized by Suzuki-Miyaura cross-coupling followed by a Knoevenagel condensation and tested for their anti-HIV-1 activity and cytotoxicity on MT-2 cells. We found that all 15 compounds had improved anti-HIV-1 activity and 3 of them (11a, 11b, and 11d) exhibited inhibitory activity against replication of HIB-1(IIIB) and 94UG103 at < 100 nM range, more than 20-fold more potent than 12 and 13, suggesting that these Compounds can serve as leads for development of novel small molecule HIV fusion inhibitors.
