Gene Information

General description

Estructura química: pirimidina

Application

El trimetoprim se utiliza principalmente como agente antibacteriano. Tiene actividad inhibidora de la dihidrofolato reductasa con selectividad por la enzima procariota. Se utiliza para tratar infecciones de las vías urinarias, prostatitis aguda leve, cistitis recurrente, bacteriuria asintomática durante el embarazo e infecciones del sistema respiratorio[1].
Se utiliza principalmente como un antibacteriano. Inhibidor de la dihidrofolato reductasa con selectividad por la enzima procariota.

Biochem/physiol Actions

La combinación de trimetoprim y sulfametoxazol interfiere en el metabolismo celular del ácido fólico en la célula bacteriana al bloquear la biosíntesis de los nucleótidos. El trimetoprim se une a la dihidrofolato reductasa e inhibe la reducción del ácido dihidrofólico (DHF) a ácido tetrahidrofólico (THF). El THF es un precursor esencial en la vía de síntesis de timidina y la interferencia con esta vía inhibe la síntesis bacteriana de ADN[1].

Questions

1–5 of 5 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
