The intramolecular cyclization of 2'-aminochalcones derived from 2- and 4-Pyridinecarboxaldehydes was carried out in the presence of Amberlyst (R)-15/AcOH media. Unexpectedly, the reaction Proceeded through a 5-exo process turning into an alternative approach for the synthesis of 2-(pyridinylmethylene)indolin-3-ones. (c) 2008 Published by Elsevier Ltd.

본 발명은 2E-1-2-아미노페닐-3-3니트로페닐-2-프로펜-1-온 (2E-1-2-Aminophenyl-3-3-nitrophenyl-2-propen-1-one; BIA) 또는 그의 유사체의 BI-1과 관련된 질병의 예방, 치료 및 개선의 용도에 관한 것이다. 본 개시내용건에서 제시한 BIA 및 그 유사체들은 BI-1 (TMBIM6)유전자의 칼슘 유리 기능을 억제하고, 이로 인하여 mTORC2와의 결합을 감소시키며, 또한 mTORC1 및 mTORC2 활성을 감소시키고 리보솜의 모집(recruitment)를 감소시키며 궁극적으로 AKT를 억제하게 되어서, 암의 성장을 저해하는 효과를 가진다.
Synthesis, antibacterial and antioxidant activities of new 1-alkyl-4-(1-alkyl-4-oxo-1,4-dihydroquinolin-2-yl)pyridinium bromides
0 μg/mL). They also showed good antioxidantactivities in DPPH scavenging (SC50: 45–133 μg/mL) and ferric reducing/antioxidant power (14–141 μM TEAC) tests. The biological activities decreased as alkyl chainlength increased. The reason behind the obvious negative effect of alkyl chain elongation is unclear and requires investigations about the intermolecular interactions of these pyridinium salts with

The molecule, which is almost completely planar, contains an intramolecular N—H...Ohydrogen bond, and the molecules are linked by a combination of N—H...N, C—H...O and C—H...π(arene) hydrogen bonds to form a three‐dimensional framework structure.
