reverse effects, with the R = Me analogue being more potent than the R = H one as well as being the most potent in the series [IC(50) in JL(C) cells 0.08 nM; superior to that for the clinical bis(naphthalimide) LU 79553]. Overall, the IC(50)s of analogues with linker chains (CH(2))(n)NH(CH(2))(m)NH(CH(2))(n) were inversely proportional to linker length. Constraining the rigidity of the linker chain by incorporating

indicative of partial agonist actions. Like spermine, the ability of these piperazine and homopiperazine derivatives to enhance [3H]MK-801 binding could be inhibited by both a competitive polyamine antagonist (arcaine) and a specific, noncompetitive polyamine antagonist (conantokin-G). However, unlike endogenous polyamines, high concentrations (up to 1 mM) of these novel polyamine-like compounds did not inhibit

Salts of triazinic compounds with phosphorus oxyacids, having the general formula (I):
obtained by salifying oligomeric derivatives of 2,4, 6-triamino-1,3,5-triazine with a phosphorus-containing acid.
The compounds with general formula (I) find use in particular as flame-retardant additives.

La présente invention a trait à un procédé pour améliorer la compatibilité des plastifiants notamment des huiles et des charges avec les polymères.
Il se caractérise par le fait que l'on met en oeuvre des compositions à additifs à base d'alcényl succinimides obtenus par condensation d'une polyamine sur un anhydre alcényl succinique dont le radical alcényle contient de 3 à 100, de préférence de 3 à 80 atomes de carbone.
Il s'applique en particulier au renforcement du caoutchouc.
