Biological Activity

Description Benzamide, a derivative of benzoic acid, is an inhibitor of poly(ADP-ribose) polymerase with an IC50 of 3.3 μM.

In vitro

Benzamide, an inhibitor of PARP is protective against excitatory amino acid-induced cell death in primary cultures of neurons derived from neonatal rat brain. In addition, benzamide has more recently been shown to partially prevent the loss of dopaminergic cells and the increase in reactive gliosis caused by METH in vitro in fetal rat mesencephalic cells in culture[1]. Benzamide prevents transformation in a cell cycle-specific manner, maximal prevention coinciding with early S phase, also characteristic of maximal susceptibility to transformation[2].

In vivo PARP inhibitor benzamide is neuroprotective in C57Bl/6N mice against different types of neurotoxicities and without affecting body temperature[2]. Benzamide treatment significantly decreases the iNOS expression and number of apoptotic neurons and thereby improves the neuronal survival and memory during GCI. Benzamide administration (160 mg/kg i.p.) does not induce hypothermia and reaches the CNS in 30 min in the concentration range of 0.09-0.64 mM, at which, it shows neuroprotection[3].

Protocol (from reference)

Cell Research:

[2]

  • Cell lines: Primary human fibroblasts
  • Concentrations: 1 mM
  • Incubation Time: 10 hr
  • Method:

    Exposure to carcinogens and benzamide is done 10 hr after the release of the metabolically induced G1/S block and exposure lasts 10 hr, followed by three washings and refeeding with fresh media.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
