, p. 313 - 320 (2014)
Cholesterol appended pyridinium urea 1 acts as low molecular weight gelator in DMSO:H2O (1:1, v/v) showing distinct colour change in the presence of aqueous solution of KF as well as tetrabutylammonium fluoride and recognises F- specifically. In addition, this hydrogel is noted to detect aqueous solution of Cu2+ and Pb2+ ions over a series of other metal ions and exhibits good semi-conducting property.

The invention provides a ureido-containing platinum pyridyl complex with an anion recognition function and a preparation method thereof. The structure of the ureido-containing platinum pyridyl complexis shown by a formula (1) as shown in the specification
Model studies on a synthetically facile series of N-substituted phenyl-N'-pyridin-3-yl ureas leading to 1-(3-pyridylcarbamoyl) indolines that are potent and selective 5-HT(2C/2B) receptor antagonists
Bromidge, Steven M.,Dabbs, Steven,Davies, David T.,Davies, Susannah,Duckworth, D.Malcolm,Forbes, Ian T.,Gadre, Angela,Ham, Peter,Jones, Graham E.,King, Frank D.,Saunders, Damian V.,Thewlis, Kevin M.,Vyas, Deepa,Blackburn, Thomas P.,Holland, Vicky,Kennett, Guy A.,Riley, Graham J.,Wood, Martyn D.

A model series of 5-HT(2C) antagonists have been prepared by rapid parallel synthesis. These N-substituted phenyl-N'-pyridin-3-yl ureas were found to have a range of 5-HT(2C) receptor affinities and selectivities over the closely related 5-HT(2A) receptor. Extrapolation of simple SAR, derived from this set of compounds, to the more active but synthetically more complex 1-(3-pyridyl-carbamoyl)indoline series allowed us to target optimal substitution patterns and identify potent and selective 5-HT(2C/2B) antagonists.
