ml-228

ML228 is a potent the Hypoxia Inducible Factor (HIF) pathway activator with EC50 of 1 μM. ML228 potently activates HIF in vitro as well as its downstream target VEGF.

Antibacterial agent 228 (Compound 8) inhibits mycobacterial ribosomes with an IC50 of 2.31 μM against Mycobacterium smegmatis. It demonstrates antibacterial activity with MIC values of 2 and 0.25 μg/mL against both wild-type and Δ1258c mutant strains of M. tuberculosis H37Rv, 8 μg/mL against wild-type and Δ2780c mutant strains of M. abscessus ATCC 19977, and 8 μg/mL against M. smegmatis.

Pradefovir (Remofovir) is a reverse transcriptase inhibitor potentially for treatment of chronic HBV infection. Pradefovir is also a liver-targeted prodrug of adefovir. After metabolic activation, Pradefovir was converted to PMEA (9-(2-phosphonylmethoxyethyl)adenine) in human liver microsomes with a K(m) of 60 microM, a maximum rate of metabolism of 228 pmol/min/mg protein, and an intrinsic clearance of about 359 ml/min.
