Paragraph 0010; 0237; 0239; 0242, (2020/03/09)
A method of producing a pluripotent stem cell is provided. The method is comprising contacting a non-pluripotent donor cell obtained from a mammalian donor with a compound characterized by general formulas (1) and (3). Furthermore, methods for inducing OCT4 and NANOG, increasing histone 3 lysine methylation and the maintenance of pluripotency are provided.

An efficient synthesis of fused imidazo-heterocycles is described using Cu(OTf)2 in [bmim]BF4 by the multi-component reaction of pyridin-2(1H)-one or thiazol/benzo[d]thiazol-2(3H)-ones with O-tosylhydroxyl amine and acetophenones under microwave irradiation. The present method is very rapid and the product formation occurs via a C-H functionalization/tandem addition-cyclization process. The ionic liquid containing copper triflate is recovered and reused four times.
NITROGENOUS HETEROCYCLIC DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING THE SAME

Page/Page column 84, (2008/06/13)
A specific derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising the compound. An organic electroluminescence device comprising at least one of organic compound layers including a light emitting layer sandwiched between an anode and a cathode, wherein said at least one of the organic compound layers comprises the derivative of the heterocyclic compound having nitrogen atom as a sole component or as mixed component. The organic electroluminescence device achieves elevation of luminance and excellent efficiency of light emission, and also achieves long lifetime by an improvement of an electrode adhesion.

Bridgehead nitrogen heterocycles were synthesized from heteroaromatic amidines and cyclic or acyclic α-bromoketones under solvent-free conditions at room temperature on a solid surface in excellent yields, which are higher than those obtained with hithert
Synthesis of [123I]N',N'-dimethyl-6-methyl-(4'-iodophenyl)imidazo[1,2-a]pyridine-3-acetamide for the study of peripheral benzodiazepine receptors using SPECT

, p. 385 - 394 (2007/10/03)
The [123I] labelled imidazo[1,2-a]pyridine [123I]iodozolpidem 4 was found to exhibit preferential activity towards Peripheral rather than Central Benzodiazepine receptors in vivo and was synthesised for the potential study of the Peripheral Benzodiazepine Receptors (PBR) using SPECT. [123I]Iodozolpidem was prepared from the corresponding tributyl tin precursor by iododestannylation with Na[123I] in the presence of peracetic acid or chloramine-T. Purification by semipreparative C-18 RP HPLC gave the product in radiochemical yields of 60-85%. The product was obtained in > 97% chemical and radiochemical puritiy with a specific activity > 80 GBq/μmol.
