| Coluracetam | 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. 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.

| Polyethyleneimine, linear | Polyethylenimine (PEI) or polyaziridine is a polymer with repeating unit composed of the amine group and two carbon aliphatic CH2CH2 spacer. Linear polyethyleneimines contain all secondary amines, in contrast to branched PEIs which contain primary, secondary and tertiary amino groups. Totally branched, dendrimeric forms were also reported. PEI is produced on industrial scale and finds many applications usually derived from its polycationic character.Linear PEI fragment Typical branched PEI fragment PEI dendrimer generation 4. Uses: Used to produce polyethyleneimine and other organic chemicals; used in the paper, textile, petroleum, lacquer, cosmetic, and photography industries. Group: Pharmaceutical. Alternative Names: Aziridine, homopolymer; Ethylenimine, polymers; Montrek 1000; Polymin FL; Tydex 12; PEI 1120; PEI 18; Montrek 6; CF 218 (polymer); PEI 6; Polyaziridine; PEI 100. CAS No. 9002-98-6. Pack Sizes: 250 mg. Product ID: B1370-356807. Molecular formula: (C2H5N)x. Mole weight: 25,000 Da. Custom synthesis is available. Send your inquiries for more information. | London |
