Abstract
Derivados de Cefalosporin piridino de la fórmula general I (gráfico), en donde R1 es hidrógeno, alquilo inferior, cicloalquilo o acetilo; X es CH o N; n es 0,1 o 2; m es 0 o 1; R2 es hidrógeno, alquilo inferior, w-hidroxi alquilo, bencilo o alquilo inferior-heterociclilo, estando el bencilo y el grupo heterociclilo insustutuido o sustituido por a lo menos uno de los grupos amino, ciano, carboxilo, hidroxilo, alquilo inferior, alcoxilo inferior o-CONR2, siendo R hidrógeno o alquilo inferior; o R2 es -CH2CON-R4R5; en donde R4, R5 son, independientemente hidrógeno, w-hidroxi-alquilo, fenilo, naftilo o heterocíclico, estando el fenilo, naftilo o heterociclilo insustituído o sustituído por a lo menos uno de los grupos de hidroxilo, opcionalmenteprotegido, halógeno, alquilo inferior opcionalmente sustituído, alcoxilo inferior opcionalmente sustituido, w-hidroxialquilo y/o ciano; o los grupos R4 y R5 forman conjuntamente un grupo de la fórmula (gráfico), con la salvedad de que m es 1, cuando el anillo de piridinio A es un piridinio-4-ilo; así como sus ésteres fácilmente hidrolizables, sales farmacéuticamente aceptables de dichos compuestos e hidratos de los compuestos de fórmula I y de sus ésteres y sales.Cephalosporin pyridine derivatives of the general formula I (graph), wherein R1 is hydrogen, lower alkyl, cycloalkyl or acetyl; X is CH or N; n is 0.1 or 2; m is 0 or 1; R2 is hydrogen, lower alkyl, w-hydroxy alkyl, benzyl, or lower alkyl-heterocyclyl, the benzyl and heterocyclyl group being unsubstituted or substituted by at least one of the amino, cyano, carboxyl, hydroxyl, lower alkyl, lower alkoxy groups. o-CONR2, where R is hydrogen or lower alkyl; or R2 is -CH2CON-R4R5; wherein R4, R5 are independently hydrogen, w-hydroxy-alkyl, phenyl, naphthyl, or heterocyclic, with phenyl, naphthyl, or heterocyclyl being unsubstituted or substituted by at least one of the hydroxyl groups, optionally protected, halogen, optionally lower alkyl. substituted, optionally substituted lower alkoxy, w-hydroxyalkyl and / or cyano; or the groups R4 and R5 together form a group of the formula (graph), except that m is 1, when the pyridinium ring A is a pyridinium-4-yl; as well as its easily hydrolyzable esters, pharmaceutically acceptable salts of said compounds and hydrates of the compounds of formula I and their esters and salts.
