Ionic Liquid-Mediated Hydrofluorination of o-Azaxylylenes Derived from 3-Bromooxindoles

The hydrofluorination reaction of 3-bromooxindole using mild HF reagents in an ionic liquid is described. This transformation can operate at room temperature to give a series of 3-substituted 3-fluorooxindole derivatives including racemic BMS 204352 (MaxiPost). The mechanistic study about interactions between HF and 3-butyl-1-methylimidazolium tetrafluoroborate [bmim][BF4] is also discussed on the basis of energy calculations.

Catalytic enantioselective fluorination of oxindoles

We have developed a highly efficient catalytic enantioselective fluorination of oxindole derivatives. In the presence of a catalytic amount of chiral Pd complex 2 (2.5 mol %), various substrates, including aryl- and alkyl-substituted oxindoles, were fluor

Use of 3-substituted oxindole derivatives as kcnq potassium channel modulators

The present invention relates to a novel method of treating of pain or anxiety, using compounds that modulate KCNQ potassium channels and currents.

Enantioselective synthesis of BMS-204352 (MaxiPost) using N-fluoroammonium salts of cinchona alkaloids (F-CA-BF4).

The enantioselective synthesis of a potent Maxi-K potassium channel opener (BMS-204352) mediated by N-fluoroammonium salts of cinchona alkaloids is described. Two synthetic pathways were evaluated. An ee as high as 88% was achieved (>99% after a single re

Methods for treating hyperactive gastric motility

This invention provides methods and pharmaceutical compositions for treating, inhibiting or preventing hyperactive gastric motility in a mammal utilizing agonists of KCNQ potassium channels, including KCNQ2, KCNQ3, KCNQ4 and KCNQ5 potassium channels, alone or in combination. The hyperactive gastric motility may be associated with maladies including, colitis, irritable bowel syndrome and Crohn's disease. Compounds useful in these methods include the 1,2,4-triamino-benzene derivatives described in U.S. Pat. No. 5,384,330 (Dieter et al.) and the substituted 3-phenyl oxindole compounds described in U.S. Pat. No. 5,565,483 (Hewawasam et al.). Among the preferred compounds of this invention is N-[2-amino-4-(4-fluorobenzylamino)-phenyl]carbamic acid ethyl ester, also referred to as retigabine.

Methods for modulating bladder function

This invention provides methods and pharmaceutical compositions for maintaining bladder control or treating urinary incontinence in a mammal utilizing agonists of KCNQ potassium channels, including KCNQ2, KCNQ3, KCNQ4 and KCNQ5 potassium channels, alone or in combination. Compounds useful in these methods include the 1,2,4-triamino-benzene derivatives described in U.S. Pat. No. 5,384,330 (Dieter et al.) and the substituted 3-phenyl oxindole compounds described in U.S. Pat. No. 5,565,483 (Hewawasam et al.).

Synthesis and structure-activity relationships of 3-aryloxindoles: A new class of calcium-dependent, large conductance potassium (maxi-K) channel openers with neuroprotective properties

A series of 3-aryloxindole derivatives were synthesized and evaluated as activators of the cloned maxi-K channel mSlo expressed in Xenopus laevis oocytes using electrophysiological methods. The most promising maxi-K openers to emerge from this study were

Discovery of a novel class of BK channel openers: Enantiospecific synthesis and BK channel opening activity of 3-(5-chloro-2-hydroxyphenyl)-1,3-dihydro-3- hydroxy-6-(trifluoromethyl)-2H-indol-2-one

3-Aryl-3-hydroxyindol-2-ones have been identified as a novel class of BK channel openers. Synthesis of both racemic and chiral 3-aryl-3-hydroxyindolones is described along with their electrophysiological evaluation as activators of the cloned BK channel m
