Description:

WARNING: This product is for research use only, not for human or veterinary use.

Emeramide, also known as NBMI, BDTH2 or N,N'-Bis(2-mercaptoethyl)isophthalamide, is a mercury/heavy metal chelator. Emeramide molecule consists of two thiol groups and linked via a pair of amide groups. NBMI can be used to chelate heavy metals like lead, cadmium, copper, manganese, zinc, iron, and mercury from ground water, coal tailings, gold ore, waste water of battery-recycling plants, and contaminated soil. WARNING: THIS PRODUCT IS A PURE CHEMICAL REAGENT IN POWDER FORM, IS INTENDED FOR RESEARCH USE ONLY, NOT FOR HUMAN USE. Qualified customers may send email to sales@medkoo.com to inquire price and procedure to order this product. To prevent non-qualified buyer to order this product, the online order for this product is not available.

Biological target:

Emeramide is a thiol-redox antioxidant and heavy metal chelator.

In vitro activity:

Even the lowest NBMI concentration (10 µM) successfully attenuated PbAc-induced toxicity by bringing the cell viability up from 42 to 83% (p < 0.0001), while the positive control DMSA did not show any impact in cell viability at even the highest concentration (100 µM) tested (Fig. 4b). Reference: Arch Toxicol. 2021 Aug;95(8):2643-2657. https://pubmed.ncbi.nlm.nih.gov/34165617/

In vivo activity:

Here this study used the nematode Caenorhabditis elegans (C. elegans) to test the efficacy of NBMI in attenuating MeHg toxicity in vivo in the whole organism. The results showed that NBMI reduced both the acute toxicity (125 μM MeHg, 1 h) and chronic (5 μM MeHg, 24 h) MeHg toxicity. Co-treatment with NBMI achieved maximal efficacy against MeHg toxicity, however delayed treatment 6 days after initiation of exposure was also effective at reducing neurotoxicity. Co-treatment of NBMI reduced the worms' death rate, structural damage in DAergic neurons, and restored antioxidant response levels.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
