Ingredient List: Coluracetam Powder
Coluracetam (full structural name of 2-(2-oxopyrrolidin-1-yl)-N-(2,3-dimethyl-5,6,7,8-tetrahydrofuro2,3-b quinolin-4-yl)acetoamide and codenames of MKC-231 or BCI-540) is a racetam compound formulated as a nootropic for the purpose of cognitive enhancement.
A known metabolite is hydroxylated coluracetam on the 2-carbon of the pyrrolidinone backbone, it is sometimes referred to as M-MKC-231. It appears inactive on the main mechanism of action coluracetam is known for (increasing HACU).
High affinity choline uptake (HACU) is the uptake of choline at the synapse for the purpose of acetylcholine synthesis, and is seen as a rate-limiting step of acetylcholine synthesis. Coluracetam appears to associated with these transporters.
Study: MKC-231, a choline uptake enhancer: (3) Mode of action of MKC-231 in the enhancement of high-affinity choline uptake. 
Abstract - MKC-231, a putative cholinergic activity, is reported to improve learning and memory impaired in AF64A-treated animals. MKC-231 enhances high-affinity choline uptake (HACU) known as the rate-limiting step of acetylcholine (ACh) synthesis. We investigated the mode of action (MOA) of HACU enhancement by MKC-231. Intracerebroventricular (i.c.v.) injections of AF64A (3 nmol/brain) resulted in significant HACU reduction in hippocampal synaptosomes. Treatment with MKC-231 increased Vmax of HACU and Bmax of [3H]-HC-3 binding 1.6 and 1.7-fold, respectively. In studies of [3H]-MKC-231 binding and Biacore analysis, MKC-231 showed noticeable affinity for cloned high-affinity choline transporters (CHT1). The present study suggests that MKC-231 directly affects trafficking of CHT1 and increases the numbers of transporter, working for HACU, at the synaptic membrane.
