Description of Anhydrotetracycline (hydrochloride)

Anhydrotetracycline (hydrochloride) es un precursor bioaint'etico de tetraciclina y un inhibidor competitivo de amplio espectro de la destructasa de tetraciclina[1]. Anhydrotetracycline (hydrochloride) es un regulador del represor de la tetraciclina (TetR) y los represores transcripcionales del represor inverso de tetraciclina (revTetR) en las c'elulas eucariotas [2]. TetR es una proteína de unión de DNA bregulada por efecttores que se une firmemente a su DNA operador teoO palindrómico en ausencia dde efectores, bloqueando así la transcripción de cualquier gen descendente [3]. Anhydrotetracycline se une mal a la subunidad ribosómica 30S, por lo que no puede actuar como un inhibidor de la traducción general y es un antibiótico pobre [4].

In vitro, el tratamiento de las células NIH3T3-HER2 con anhidrotetraciclina (clorhidrato) (10 ng/ml) durante 3 días resultó en la regulación a la baja del gen HER2 por debajo del límite de detección [5]. El tratamiento de células N1 con anhidrotetraciclina (clorhidrato) (10-200nM) durante 7 días redujo significativamente el nivel de expresión del gen GUS impulsado por Top10[6].

In vivo, el tratamiento de ratones con un modelo tumoral basado en células NIH3T3-HER2 con anhidrotetraciclina (clorhidrato) (10mg/kg; s.c.) resultó en una regresión tumoral de más del 95% en 7 días[5]. El tratamiento de ratones con el modelo tumoral basado en células NIH3T3-HER2 con anhidrotetraciclina (clorhidrato) (10mg/kg; i.p.) indujo la regulación a la baja del ERBB2 mRNA, lo que llevó a una rápida reducción en el volumen tumoral[7].

Protocol of Anhydrotetracycline (hydrochloride)

Experimentos celulares [1]:

Líneas celulares

Células NIH3T3-HER2

Método de preparación

Las células NIH3T3-HER2 se recolectaron de platos de cultivo confluentes en un 90% y se colocaron en 105 células por plato en frascos de 75 cm2 . Después de 24 horas, las células se incubaron con 10 ng/ml de 4-epoxiciclina o Anhydrotetracycline clorhidrato) durante 3 días.

Condiciones de reacción

10 ng/ml; 3 días

Áreas de aplicación

Anhydrotetracycline (clorhidrato) y 4-epidoxycycline dieron como resultado la regulación a la baja de HER2 por debajo del límite de detección.
Experimentos con animales [2]:

Modelos animales

Ratones desnudos machos

Método de preparación

Las células NIH3T3-HER2 se inyectaron por vía subcutánea en la piel dorsal de ratones desnudos machos de tres a cuatro semanas de edad. Tan pronto como los tumores alcanzaron un volumen de 1.6 cm3 , ratones fueron asignados a uno de los cuatro grupos de tratamiento: (i) doxiciclina, 7.5 mg/ml en agua potable, (ii) 4-epidoxycycline, 7.5 mg/ml en agua potable, (iii) inyecciones subcutánes diarias de 4-epidoxycycline de 10 mg/kg de peso corporal, y (iv) Anhydrotetracycline (clorhidrato) inyecciones subcutáneas diarias de 10 mg/kg de peso corporal.

Forma de dosificación

10 mg/kg; s.c.

Áreas de aplicación

Doxycycline, 4-epidoxycycline y Anhydrotetracycline (clorhidrato) provocaron una rápida remisión tumoral en 7 días. La inyección subcutánea y la adminitración en agua potable produjeron efectos similares.
