Description
cuya divulgación se incorpora en el presente documento por referencia. Los aminoácidos no naturales también incluyen α-aminoácidos en los que las cadenas laterales se reemplazan con derivados sintéticos. En determinados modos de realización, los grupos sustituyentes para los compuestos de la presente invención incluyen el residuo de un aminoácido después de retirar el resto hidroxilo del grupo carboxilo del mismo; es decir, grupos de fórmula C(=O)CH(cadena lateral)-NH2. A continuación en la tabla A se muestran cadenas laterales representativas de αaminoácidos naturales y no naturales.

[1,3,2]dioxaborolan-2-il)-fenoxi]-propil}-pirrolidina (11,76 g, 34 mmol) en una mezcla de THF (200 ml) y EtOH (100 ml) y se añadió gota a gota a la mezcla de reacción. Se introdujo solución saturada de NaHCO3 (360 ml). Se calentó la mezcla de reacción a 80 °C durante 15 h, se enfrió y se evaporó hasta un residuo, que se llevó a CH2Cl2 (300 ml) y se lavó con agua y solución saturada de NaHCO3. La fase de CH2CI2 se secó (Na2SO4) y se evaporó. Se obtuvo el 5 producto por cromatografía ISCO en gel de sílice, eluyendo con EtOAc inicialmente y después con una mezcla de EtOAc/CH3OH (9:1) para proporcionar el compuesto del título (10,20 g, 90 %) como un sólido color crema con p.f. de 107-108,5 °C; RMN de 1H (CDCl3) 1,10 (d, 3H, -CH3), 2,99 (m, 2H, -CH2-), 3,18 (m, 2H, -CH2-), 4,10 (m, 2H, -CH2-), 7,04 (d, 2H, Ar-H), 7,50 (d, 1H, C-H), 7,78 (d, 1H, C-H), 7,99 (d, 2H, Ar-H) (solamente señales representativas); tiempo de retención de HPLC 6,893 min.

Modelo de dipsogenia: Inhibición del consumo de agua inducido por agonistas de la histamina en la rata.
La histamina y el agonista selectivo de H3 (R)-α-metilhistamina (RAMH) inducen el consumo de agua en la rata cuando se administran de forma periférica o central (Kraly, F.S., June, K.R. 1982 Physiol. Behav. 28: 841.; Leibowitz,
10 S.F. 1973 Brain Res. 63:440; Ligneau X., Lin, J-S., Vanni-Mercier G., Jouvet M., Muir J.L., Ganellin C.R., Stark H., Elz S., Schunack W., Schwartz, J-C. 1998 J Pharmcol. Exp. Ther. 287:658-66; Clapham, J. y Kilpatrick G.J. 1993 Eur. J. Pharmacol. 232:99-103), un efecto que bloquean los antagonistas del receptor H3 tioperamida y ciproxifano. Los compuestos de la invención han demostrado o se espera que bloqueen la inducción del consumo de agua por la RAMH.
