Abstract:
Sterically hindered phosphoramidates such as N, N'-bis[di-(2,6-xylenoxy)phosphinyl]piperazine are prepared by the reaction of a sterically hindered diaryl chlorophosphate, such as di-(2,6-xylyl) chlorophosphate, with a basic nitrogen compound containing at least two basic N-H groups, preferably a heterocyclic compound such as piperazine, in a predominantly liquid, solvent-free reaction mixture. The reaction my be conducted in the melt or in the presence of a non-solvent carrier, typically an aliphatic hydrocarbon. An excess of the basic nitrogen compound is employed as an acid acceptor.
Abstract:
The present invention provides amidophosphate derivatives useful for potentiating glutamate receptor function in a mammal and therefore, useful for treating a wide variety of conditions, such as psychiatric and neurological disorders.
Abstract:
Disphosphonates, or their salts between disphosphonic acids and linear, branched substituted and non-substituted, cyclic, hetero-cyclic and aromatic amino-alcohols, and their use in the treatment of osteoporosis, and pharmaceutical compositions that contain at least one diphosphonate as active principle for the treatment of osteoporosis.
Abstract:
The invention relates to acetic acid derivatives of formula (I) and pharmaceutically acceptable derivatives thereof and salts and solvates thereof, in which X?1 and Y1¿, which may be the same or different, represent CH or N; X2 represents CH or, when X1 represents CH, may also represent N; Y2 represents N or, when Y1 represents N, may also represent CH; Z represents N or N+R5; R1 represents a hydrogen atom or a hydroxyl, C¿1-4?alkyl or 2,2,2-trifluoroethyl group; R?2¿ represents a hydrogen atom or, when both X?1 and X2¿ represent CH, may also represent a fluorine, chlorine or bromine atom or a C¿1-4?alkyl group; R?3¿ represents a hydrogen atom or, when both Y?1 and Y2¿ represent N, may also represent a C¿1-4?alkyl or hydroxymethyl group. R?4¿ represents a hydrogen atom or, when Z represents N, R4 may also represent a C¿1-4?alkyl group; R?5¿ represents a C¿1-4?alkyl or phenylC1-4alkyl group; R?6¿ represents a hydrogen atom or a C¿1-4?alkyl group. The compounds inhibit fibrinogen-dependent blood platelet aggregation.
Abstract:
The present invention relates to herbicidally active cinnolinium derivatives and formulations comprising such derivatives. The invention further extends to herbicidal mixtures comprising a cinnolinium derivative as described herein and at least one additional herbicidal active ingredient. The use of the afore-mentioned cinnolinium derivatives, formulations and/or herbicidal mixtures in controlling undesirable plant growth: in particular the use for the post-emergence control of weeds, also falls within the scope of the present invention.
Abstract:
La présente invention concerne une nouvelle classe de petites molécules anticancéreuses dérivées de l'acide éthacrynique (symbolisé par AE). L'invention concerne les activités anticancéreuses in vitro et in vivo et les procédés de préparation de la nouvelle famille de l'AE. De nouveaux analogues de l'AE ont été synthétisés puis, leurs activités cytotoxiques in vitro ont été évaluées sur la lignée cellulaire tumorale P815 en utilisant le test MTT. Le dérivé de l'AE, qui a présenté la meilleur cytotoxité in vitro , a été ensuite testé in vivo en utilisant le modèle de souries DBA2/P815 (H 2 d). A 30 mg/kg, la dose effective, les animaux ont montré une tolérance générale avec un pourcentage de survie aux alentours de 80%, et aucune perte de poids significative n'a été observée
