Description générale

1,1-Dimethylbiguanide hydrochloride (metformin) is a strong base. It forms well defined salts and possessing excellent coordination capacity with transition metals, forming highly colored bidentate chelate complexes.[1] Metformin (MET) exists in various forms: diprotonated (H2MET)2+ in strong acidic solution, monoprotonated (HMET)+ in weak acid, MET in neutral and deprotonated (MET)- in strong alkali solution.[2] It is an oral antidiabetic drug. Pharmacokinetics of metformin has been studied.[3] Determination of metformin in human plasma has been described by simple HPLC-UV method.[4] Metformin is reported to increase plasma active glucagon-like peptide-1 (GLP-1) in humans.[5]

Metformin is used as an organic base catalyst for the transesterification of coconut oil with methanol.

Application

1,1-Dimethylbiguanide hydrochloride is suitable biguanide agent used in a study to investigate its role in enhancing the secretions of plasma active glucagon-like peptide-1 (GLP-1) levels.[5] It may be used in the synthesis of the following:
  • bis(1,1-dimethylbiguanido)copper(II) octahydrate[1]
  • bis(1,1-dimethylbiguanido)nickel(II)[2]
  • 1,1-dimethylbiguanidium tetrabromothallate(III)[6]

Actions biochimiques/physiologiques

Metformin is an antidiabetic agent that reduces blood glucose levels and improves insulin sensitivity. Its metabolic effects, including the inhibition of hepatic gluconeogenesis, are mediated at least in part by activation of the LKB1-AMPK (AMP-activated protein kinase) pathway. Activation of this pathway also appears to be involved in the antiproliferative and proapoptotic actions of metformin in cancer cell lines.

Metformin was reported to increase plasma active glucagon-like peptide-1 (GLP-1) in humans. There are two possible mechanisms for this effect: (1) metformin inhibits dipeptidyl peptidase IV (DPPIV), an enzyme degrading GLP-1, and (2) metformin enhances GLP-1 secretion. To elucidate the

Questions

1–7 sur 7 questions  

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

    1 réponse

    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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 réponse

    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.
