Background:

DBIBB, a butylsulfamoyl benzoic acid analog, is a non-lipid agonist of LPA2 with an EC50 of 0.10 μM. DBIBB has no effect at other LPA receptor subtypes [1]. The bioactive phospholipid lysophosphatidic acid (LPA) has been involved in stimulating cell proliferation, migration and survival by acting on its cognate G-protein-coupled receptors. Aberrant LPA production, receptor expression and signalling probably contribute to cancer initiation, progression and metastasis [2].


In vitro: DBIBB treatment postirradiation significantly (p< 0.01) increased the clonogenic survival of IEC-6 cells in the 2-6 Gy dose range. DBIBB reduced DNA fragmentation 4hr after irradiation in a dose dependent manner. DBIBB also reduced caspase 3/7 activity and DNA fragmentation in LPA2MEF treated with adriamycin. In purified CD34+ progenitor cells, DBIBB significantly increased the total number of colonies and specifically enhanced the survival of the granulocyte/macrophage lineages [1].


In vivo: Using a murine GI-ARS mice model of partial-body irradiation (PBI) with shielding of the bone marrow contained in the tibiae, fibulae, and paws, administrations of up to 10 mg/kg of DBIBB for 10 days showed no visually observable adverse effects and pathological findings at necropsy, indicating the lack of toxicity. The group that received 10 mg/kg DBIBB showed a significant increase in survival. In C57BL/6 mice, DBIBB showed a dose-dependent increase in the number of surviving crypts compared with the vehicle control [1].
