Aminosterol compounds are described that are useful as inhibitors of the sodium/proton exchanger (NHE). Methods of using such aminosterols compounds are also disclosed, including those employing compounds that are inhibitors of a spectrum of NHEs as well as those using compounds that are inhibitors of only one specific NHE. Advantageous screening techniques and assays for evaluating a compound's therapeutic activity are also disclosed.

[EN] Methods for the chemical preparation or synthesis of the sterol antibiotic squalamine. Preferably, the preparation is by modifying the 3-position of a 3-oxo-7 alpha -hydroxy-24 zeta -ether protected alcohol group-5 alpha -cholestane with a spermidino moiety to form a 3 beta -spermidino-7 alpha -hydroxy-24 zeta -ether protected group -5 alpha -cholestane; deprotecting the 24-position of the 3 beta -spermidino-7 alpha -hydroxy-24 zeta -ether protected group-5 alpha -cholestane to the free hydroxyl; and sulfating the 24-position of the 3 beta -spermidino-7 alpha , 24-dihydroxy-5 alpha -cholestane. [FR] L'invention se rapporte à des procédés de préparation ou synthèse chimique de la squalamine, un antibiotique stérolique. On effectue de préférence la préparation en modifiant la position 3 d'une fonction alcool-5alpha-cholestane protégée par un 3-oxo-7alpha-hydroxy-24zeta-éther avec une fraction spermidino afin de former une fonction -5alpha-cholestane protégée par un 3beta-spermidino-7alpha-hydroxy-24zeta-éther; en déprotégeant la position 24 de la fonction -5alpha-cholestane protégée par un 3beta-spermidino-7alpha-hydroxy-24zeta-éther pour obtenir l'hydroxyle libre; et en sulfatant la position 24 du 3beta-spermidino-7alpha, 24-dihydroxy-5alpha-cholestane.
