Biochem/physiol Actions

MDL-860 is a 5-nitro-2-phenoxybenzonitrile that exerts broad-spectrum antipicornaviral activity (MIC50 from 0.1-1.5 μg/mL in HeLa cultures) by acting as an irreversible inhibitor against host phosphatidylinositol-4 kinase beta (PI4KB; PtdIns 4-kinase beta; PI4Kbeta; NPIK; PI4K92) via covalent modification of Cys646 located at the bottom of a surface pocket apart from the PI4KB active site. MCL-860 (MIC50 from 0.1-1.5 μg/mL in HeLa cultures). A pleconaril/MDL-860/oxoglaucine consecutive alternating administration (CAA), but not simultaneous daily treatment, is reported to be effective against coxsackievirus B1 infection without the development of drug resistance in newborn mice (75 mg/kg MDL-860 via s.c. every third day on the day following pleconaril and prior to oxoglaucine).

A nitrobenzene derivative, MDL-860, was found to inhibit plaque formation, cytopathic effect, or both in 11 of 12 picornaviruses at concentrations which did not affect cell growth. The compound did not directly inactivate the virus. MDL-860 inhibited actinomycin D-resistant [3H]uridine

MDL-860 is a broad-spectrum antipicornavirus compound discovered in 1982 and one of the few promising candidates effective in in vivo virus infection. Despite the effectiveness, the target and the mechanism of action of MDL-860 remain unknown. Here, we have characterized

The newly synthesized compound 2-(3,4-dichlorophenoxy)-5-nitrobenzonitrile (MDL-860) has been found to inhibit picornavirus replication. In multiple growth cycle experiments, 1 microgram of MDL-860 per ml caused a reduction in virus yield of at least 1.0 log10 50% tissue culture infectious doses

Bioorganic & medicinal chemistry letters, 27(19), 4540-4543 (2017-09-06)
A series of twelve novel compounds, analogues of antiviral agent MDL-860 were synthesized and their antiviral activity was evaluated in vitro against enteroviruses poliovirus 1 (PV1), Coxsackieviruses B1 (CVB1) and Coxsackieviruses B3 (CVB3). Compounds 14, 24 and 25 manifested strong
