-
Page/Page column 44, (2009/04/24)
The present invention relates to a compound of the formula I wherein R1 to R6, A, B, n and m are as defined herein. Such novel sulfonyl amide derivatives are useful in the treatment of abnormal cell growth, such as cancer, in mammals. This invention also relates to a method of using such compounds in the treatment of abnormal cell growth in mammals, especially humans, and to pharmaceutical compositions containing such compounds.

4-Azidopyridines such as 3-acetyl-4-azido-2-pyridones 3 or 4-azido-3-ethoxycarbonylpyridine 7 with reactive ortho-acyl substituents were obtained from the 4-hydroxy-2-pyridones 1, resp. 5 via 4-tosyloxy-2-pyridones 2 or the 2,4-dichloropyridine 6. DSC-ass
An Easy and Convenient Synthesis of 6-Methyl-4(1H)-pyridone-3-carboxylic Acid
Mittelbach, Martin
, p. 479 - 480 (2007/10/02)
A new and easy synthesis of 6-methyl-4(1H)-pyridone-3-carboxylic acid (5), an important component of broad spectrum cephalosporins, is described.It starts from the readily available ethyl 4-hydroxy-6-methyl-2(1H)-pyridone-3-carboxylate (1), which is treated with phosphoryl chloride to give ethyl 2,4-dichloro-6-methylpyridine-3-carboxylate (2).Selective substitution of the chlorine in 4-position with alkoxide ion leads to the 4-alkoxypyridine derivatives 3.Hydrogenolysis of 3 affords ethyl 4-alkoxy-6-methyl-pyridine-3-carboxylates 4; which are hydrolysed to 5 in one step.
Aza Analogues of Lucanthone: Synthesis and Antitumor and Bactericidal Properties
Croisy-Delcey, Martine,Bisagni, Emile
, p. 1329 - 1333 (2007/10/02)
Three types of aza analogues of lucanthone were synthesized for evaluation as antitumor drugs.None of the compounds was found to have significant cytotoxic effects either on Friend tumor cells or on L1210 leukemia cells.However, one of the target compound
