• 使用

  Bongkrekic acid solution has been used as an adenine nucleotide translocator (ANT) inhibitor to find out a different approach for the inhibition of oxidative phosphorylation in intact T98G cells. It has also been used as an inhibitor of the permeabilization transition pore complex (PTPC) pore and a tool to explore the role of PTPC in induction of apoptosis.

• 定義

  ChEBI: A tricarboxylic acid that is docosa-2,4,8,10,14,18,20-heptaenedioic acid substituted at positions 2 ,5 and 17 by methyl groups, at positions 6 by a methoxy group and at position 20 by a carboxymethyl group.

• 酵素阻害剤

  This toxic tricarboxylic acid (FWfree-acid = 486.61 g/mol; CAS 11076-19-0), produced Pseudomonas cocovenenans, is a potent competitive inhibitor of the mitochondrial ATP-ADP translocator, effectively blocking nucleotide binding to the carrier. The name is derived from bongkrek, a moldy coconut product produced in Indonesia. The toxin accumulates when P. cocovenenans outgrows the mold. Klingenberg et al. investigated bongkrekate binding to mitochondrial membrane to examine the reorienting site mechanism. The inferred mode of inhibition requires bongkrekate to bind to the single carrier site only from the inner face of the mitochondrial membrane (i.e., the matrix side)). They confirmed the pH-dependent accumulation of [3H]bongkrekate inside the mitochondria which superimposes onto the binding at carrier sites. By breaking the membrane with Lubrol or sonication, binding to the carrier sites could be titrated, and a Kd value of approximately 5 x 10–8 M was determined. The presence of ADP or ATP increases the amount of binding but does not alter the Kd. [35S]Atractylate is displaced by [3H]bongkrekate at a 1:1 molar ratio; this displacement is dependent on ADP concentration with the Km = 0.5 x 10–6 M. See also Atractyloside The isomer known as isobongkrekic acid, which has a cis-double bond at the dicarboxylic acid end of the molecule, has similar biological activity. Target(s): Adenine nucleotide translocator, ADP/ATP carrier; ATPase; bromelain, stem; papain; ficain, or ficin.
