Design, synthesis and evaluation of carbamate-modified (−)-N1-phenethylnorphysostigmine derivatives as selective butyrylcholinesterase inhibitors

Molecular modeling studies for exploring structural requirement of acetylcholinesterase inhibitors

“…In this work, a set of structurally diverse compounds (n = 225) [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], having AChE inhibitory activity (IC 50 in nM), have been considered for modeling study. The compounds were divided into training and test sets by k-means clustering.…”

Butyrylcholinesterase - BuChE: A Potential Target for Development of Drugs for Alzheimer's Disease Treatment

“…Takahashi e colaboradores descreveram uma série de inibidores potentes e seletivos para BuChE baseados em modificações estruturais no núcleo da norfisostigmina. 116 Baseando-se no potente e seletivo inibidor de BuChE descrito por Brus (31, CI 50 hBuChE = 2,7 nM), 94 Kosak e colaboradores propuseram uma série de modificações moleculares, como a troca bioisostérica da subunidade amida pelo grupo sulfonamida e a troca do núcleo di-idroindeno pelo grupo benzila. 121 As modificações propostas levaram a uma nova série de derivados sulfonamídicos que culminou na identificação de um novo inibidor reversível e seletivo de hBuChE: a sulfonamida 60 com 4,9 nM de CI 50 para hBuChe.…”

Regioselective, One‐Pot, Three‐Component Synthesis of 1,3,4‐ and 1,3,5‐Triarylpyrazoles from 1‐ and 2‐Aryl‐1‐alkenyl Sulfones

“…We have developed and reported one-pot, or one-flow, multicomponent coupling methods for the efficient synthesis of organic compounds. [26][27][28][29][30][31][32][33] As part of our drug development research into Alzheimer's disease [31,34,35] based on triarylpyrazoles, we decided to develop a rapid, one-pot approach for the synthesis of a structurally diverse triarylpyrazole library. In this paper, we report the regioselective onepot, three-component synthesis of 1,3,4-and 1,3,5-triarylpyrazoles from readily available starting materials: aryl aldehydes, aryl hydrazines, and 1-and 2-aryl-1-alkenyl sulfones (Scheme 1, b).…”
