, p. 7831 - 7836 (2021)
Understanding the fundamental facts behind dynamicity of catalytic processes has been a longstanding quest across disciplines. Herein, we report self-assembly of catalytically active gold nanorods that can be regulated by tuning its reactivity towards a p
Vesicles accelerate proton transfer from carbon up to 850-fold

, p. 127 - 130 (2000)
(equation presented) We have analyzed the different catalytic effects of surfactant aggregates upon the rate-determining hydroxide ion induced deprotonation reaction of 1. Vesicles are more effective catalysts than micelles, most likely providing a more a
Investigation of medium effects in a family of decarboxylase antibodies
Tarasow,Lewis,Hilvert
, p. 7959 - 7963 (1994)
A family of naphthalenedisulfonate-binding antibodies catalyze the decarboxylation of 5-nitro-3-carboxybenzisoxazole, providing a series of structurally similar catalysts for investigating the influence of protein microenvironment on reactivity. Eight rep
Mechanistic study of proton transfer and hysteresis in catalytic antibody 16E7 by site-directed mutagenesis and homology modeling
Zheng, Lei,Manetsch, Roman,Woggon, Wolf-Dietrich,Baumann, Ulrich,Reymond, Jean-Louis
, p. 1021 - 1029 (2005)
Antibody 16E7 catalyzes the carbon protonation of enol ether 2 to hemiacetal 3, and the carbon deprotonation of benzisoxazole 7 to phenol 8. This antibody shows an extreme case of hysteresis, requiring several hours to reach full activity. Antibody 16E7 w
Characterization of proton-transfer catalysis by serum albumins
Hollfelder, Florian,Kirby, Anthony J.,Tawfik, Dan S.,Kikuchi, Kazuya,Hilvert, Donald
, p. 1022 - 1029 (2000)
Two independent investigations of catalysis by BSA and other serum albumins are combined to provide detailed insight into the mechanism of a classical proton-transfer reaction taking place on the surface of a protein. The Kemp elimination involves the gen
Influence of water-soluble pillararene hosts on Kemp elimination

Since pillar[5]arene was first discovered in 2008, it has developed into a multifunctional supramolecular host. Its application covers many fields from drug delivery and chemical sensing to the construction of molecular machines, and so on. Supramolecular
Design, synthesis, and biological evaluation of 5-(4-(pyridin-4-yl)-1H-1,2,3-triazol-1-yl)benzonitrile derivatives as xanthine oxidase inhibitors

, p. 526 - 533 (2017/10/23)
A series of 5-(4-(pyridin-4-yl)-1H-1,2,3-triazol-1-yl)benzonitrile derivatives (1a–p) was designed, synthesized, and identified as xanthine oxidase inhibitors with micromolar level potencies. Among them, the most promising compounds 1j and 1k were obtained with IC50 values of 8.1 and 6.7?μm, respectively. The Lineweaver–Burk plot revealed that compound 1k acted as a mixed-type xanthine oxidase inhibitor. SAR analysis revealed that a carbon atom occupying the X3 position is not as effective as a nitrogen atom, and an iso-pentyloxy or a cyclopentyloxy at the 2-position of benzonitrile moiety will benefit the inhibitory potency. The basis of xanthine oxidase inhibition by 1k was rationalized by molecular modeling studies.
