摘要:
The process for the preparation of chiral 3-(1-amino-1,1-bisalkylmethyl)-1-substituted-pyrrolidines used as key intermediates for the preparation of naphthyridine and quinolone antibacterial agents which comprises reacting readily available chiral 1-substituted-3-pyrrolidinols to their corresponding chiral sulfonate esters; converting the sulfonate esters to chiral 1-substituted-3-cyanopyrrolidines having an inverse configuration, and then dialkylating the chiral cyanopyrrolidines with alkyl lithium in the presence of a Lewis acid without racemization at the asymmetric carbon atom is described.
摘要:
Novel 8-alkenyl, alkynyl, allenyl and cycloalkyl-quinolinecarboxylic acids are described as antibacterial agents as well as methods of manufacture including novel intermediates used in said manufacture.
摘要:
The present invention is a novel process for preparing both known and novel nitroimidazoles having novel intermediates. The process advantageously reduces the number of process steps, provides increased yield with both greater safety and greater control of stereoisomerism in the products.
摘要:
Optically pure isomers of 7-[3-(1,1-dialkylmethyl-1-amino)-1-pyrrolidinyl]quinolones and naphthyridones as therapeutically active and safe antibacterial agents are described, as well as pharmaceutical compositions thereof, and a method of treating bacterial infections therewith. Also described is a method of manufacture of the quinolones and naphthyridones as well as the starting materials, the optically pure pyrrolidine moieties for attachment at the 7-position.
摘要:
The present invention is novel nitroimidazoles useful as radiosensitizing or chemosensitizing agents in the treatment of hypoxic tumor cells. Also, the present invention is a novel process for preparing both known and novel nitroimidazoles having novel intermediates. The process advantageously reduces the number of process steps, provides increased yield with both greater safety and greater control of stereo-isomerism in the products.
摘要:
Novel purine derivatives are described as agents for treating autoimmune diseases as well as a method of manufacture and pharmaceutical compositions as well as novel intermediates in the manufacture thereof.
摘要:
Compounds, compositions and methods are provided which are useful in the treatment of diseases through the inhibition of sodium ion flux through voltage-gated sodium channels. More particularly, the invention provides substituted aryl sulfonamides, compositions comprising these compounds, as well as methods of using these compounds or compositions in the treatment of central or peripheral nervous system disorders, particularly pain and chronic pain by blocking sodium channels associated with the onset or recurrence of the indicated conditions. The compounds, compositions and methods of the present invention are of particular use for treating neuropathic or inflammatory pain by the inhibition of ion flux through a voltage-gated sodium channel.

Compounds, compositions and methods are provided which are useful in the treatment of diseases through the inhibition of sodium ion flux through voltage-gated sodium channels. More particularly, the invention provides heterocyclic aryl sulfonamides, compositions and methods that are useful in the treatment of central or peripheral nervous system disorders, particularly pain and chronic pain by blocking sodium channels associated with the onset or recurrence of the indicated conditions. The compounds, compositions and methods of the present invention are of particular use for treating neuropathic or inflammatory pain by the inhibition of ion flux through a voltage-gated sodium channel.
摘要:
Compounds having utility as anti-inflammatory agents in general and, more specifically, for the prevention and/or treatment of immunoinflammatory and autoimmune diseases are disclosed. The compounds are pyrimidine-containing compounds and, in one embodiment, are esters of the same. Methods are also disclosed for preventing and/or treating inflammatory conditions by administering to an animal in need thereof an effective amount of a compound of this invention, preferably in the form of a pharmaceutical composition.
