ARUNDIC ACID (ONO-2506) is an enantiomeric, three carbon atom homolog of valproic acid under development by ONO Pharmaceutical for the potential treatment of stroke, as well as Amyotrophic Lateral Sclerosis and Parkinson's disease. The injectable formulation (Proglia) is finished phase III trials for acute-phase cerebral infarction, and the oral formulation (Cereact) is finished phase II trials in the UK for Alzheimer's disease (AD) and Parkinson's disease (PD). ARUNDIC ACID restores normal astrocyte functions after brain damage by preventing reactive astrocytosis, by activating astrocytic GABAA receptors and suppressing GABA transferase. ARUNDIC ACID inhibits S-100β synthesis in activated cultured astrocytes. This agent has additional antiglutamate and antiinflammatory COX-2 inhibitor properties

In Vitro Use Guide

E13.5 embryos were dissected in filter sterilized Krebs (containing the following in mM: 120.9 NaCl, 5.9 KCl, 1.2 MgCl2, 1.2 NaH2PO4, 14.4 NaHCO3, 2.5 CaCl2, and 11.5 glucose). The entire embryonic gut, including the stomach, small intestine and colon, was removed and pinned in small Sylgard dishes using 50 mm diameter tungsten wire, as described previously (Shyer et al., 2013). Gut explants were cultured in 2 ml of DMEM/F12 with 1% penicillin/streptomycin. Arundic acid (ONO-2506, Tocris Bioscience, catalog #4530) was dissolved in DMSO and added to the culture media. S100B (Sigma, cat #A6677) was dissolved in Krebs or Dulbecco’s phosphate buffered saline (DPBS) and also added to the culture media, either alone, or in combination with arundic acid. Appropriate vehicle control cultures were also performed. All preparations were incubated for 48 h at 37_C, 5% CO2 with media refreshed at 24 h.
