N-(2-Aminophenyl)pyrazine-2-carboxamide

Description

BG45 is an HDAC class I inhibitor with selectivity for HDAC3 (IC₅₀ = 289 nM). It inhibits HDAC1, HDAC2, and HDAC6 with greatly reduced potency (IC₅₀s = 2, 2.2, and >20 μM, respectively). At concentrations up to 50 mg/kg, BG45 alone or in combination with bortezomib has been shown to dose-dependently inhibit tumor growth in a mouse model of multiple myeloma.

The Uses of N-(2-Aminophenyl)pyrazine-2-carboxamide

BG45 acts as an HDAC class I inhibitor with selectvity for HDAC3. HDACs represent novel targets for anti-tumer drugs treating various cancers including multiple myeloma cancer.

Definition

ChEBI: N-(2-aminophenyl)-2-pyrazinecarboxamide is an aromatic amide.

in vitro

bg45 is reported as an hdac class i inhibitor with selectivity for hdac3 over hdac1, 2. consistent with hdac3 knockdown data, bg45 significantly inhibited mm cell growth dose-dependently. importantly, bg45 also triggered a potent growth inhibitory effect against patient-derived mm cells, without affecting normal donor pbmcs [1].

in vivo

bg45 significantly inhibited mm tumor growth in a dose-dependent fashion. for example, significant differences were observed in control versus bg45 15 mg/kg, control versus bg45 50 mg/kg, and bg45 15 mg/kg versus bg45 50 mg/kg at day 22. moreover, bg45 50 mg/kg in combination with bortezomib enhanced either single agent activity further. these results confirmed that bg45 triggers in vivo anti-mm activities [1].
