BIOLOGICAL ACTIVITY:
Coluracetam(MKC-231) is a new choline uptake enhancer. IC50 value: Target: in vitro: MKC-231 (10(-10)-10(-6) moll) significantly
increased high affinity choline uptake (HACU) when it was incubated with the hippocampal synaptosomes of ethylcholine mustard
aziridinium ion (AF64A) treated rats, but not of normal rats. MKC-231 did not affect the AChE activity, [3H]- quinuclidinyl benzilate
binding, and [3H]-pirenzepine binding [1]. in vivo: Oral administration of MKC-231 (1-10 mg/kg) significantly improved the learning
deficits in the Morris’ water maze of AF64A-treated rats, but it did not produce any significant side effects, like tremor, salivation or
hypothermia, which were observed in rats treated with high doses of tacrine [1]. In acute behavioral experiments, MKC-231 and THA
had no significant effect on AF64A-induced memory deficits at any doses tested (0.3, 1.0 and 3.0 mg/kg), whereas Dup 996, at a
dose of 1.0 mg/kg, significantly improved memory deficits. In chronic experiments, MKC-231 improved memory deficit at all doses
tested (0.3, 1.0, or 3.0 mg/kg p.o., once daily for 11 days) and Dup 996 did so only at a dose of 3.0 mg/kg, whereas THA did not
improve memory deficit at any doses tested [2].
