Methylene Blue (5mg-60)

In Stock

Nomenclature & Synonyms

Methylene blue, also scientifically known as tetramethylthionine chloride, is a heterocyclic aromatic chemical compound. It is frequently referred to in research by its chemical name and has been used historically in various applications, although specific research codes have not been consistently applied to this compound.

Structural Characteristics

Methylene blue does not consist of an amino acid sequence as it is a phenothiazine derivative. It has a tricyclic phenothiazine structure, featuring a central sulfur and nitrogen atom with methyl substitutions that influence its redox properties. The compound is not derived from a larger protein fragment, but its planar aromatic structure is crucial for its electron transfer capability.

Molecular Pharmacology

Methylene blue primarily functions by inhibiting the enzyme guanylate cyclase, thus impacting the NO-cGMP pathway. This interference can modulate vascular tone and neurotransmitter release. It has also been noted to act as a redox agent, accepting and donating electrons through alteration in its oxidation states. EC50 values vary depending on the cellular context, but it can modulate several cellular processes via its electron transfer roles.

Research Applications

  • Methylene blue was first synthesized by Heinrich Caro in 1876 and has been extensively explored in histological staining, serving as a vital stain in various cellular and microbiological applications.
  • Studies have demonstrated its utility in exploring mitochondrial function due to its ability to carry electrons across membranes.
  • Investigative uses in neuropharmacology due to its inhibition of monoamine oxidase (MAO) and exploration in neuroprotective roles have been documented.

Technical Properties

Methylene blue is highly soluble in water, particularly at concentrations such as 1mg/mL, making it conducive for aqueous applications. Reconstitution is recommended in sterile water or appropriate buffer solutions. Stability data suggest that it remains stable in lyophilized form and must be handled under light-limiting conditions due to its photolabile nature.

Compliance

For laboratory research use only. Not for human or veterinary use. Not intended for diagnostic, therapeutic, or preventive applications.

Tesofensine (500mcg-60)
CAPSULE

Tesofensine (500mcg-60)

Nomenclature & Synonyms

The full chemical name for Tesofensine is (3R)-1,3,4,5-tetrahydro-3-[2-(dimethylamino)ethyl]-2-benzofuran-5-ol. It is referred to as NS-2330 in early development stages, and its parent compound is derived from sibutramine, though it is not a direct fragment or analog. Alternative naming in literature includes the designation Tesofensine without additional numeric codes.

Structural Characteristics

Tesofensine is not a peptide and thus lacks an amino acid sequence; it is a small organic molecule without recognizable peptide modifications. However, its molecular conformation is non-linear, with a distinct benzofuran moiety that contributes to its biological activity.

Molecular Pharmacology

Tesofensine is a potent inhibitor of presynaptic reuptake of norepinephrine, dopamine, and serotonin. It has been shown to act as an indirect agonist at these monoaminergic pathways. Studies indicate that it increases extracellular concentrations of these neurotransmitters, exerting its pharmacological effects through modulation of monoaminergic signaling cascades. The pharmacological profile includes a higher binding affinity for the serotonin transporter (SERT) compared to norepinephrine (NET) and dopamine (DAT) transporters. Precise EC50/IC50 values can vary across studies.

Research Applications

  • First synthesized in the early 2000s by NeuroSearch, Tesofensine has been extensively studied in neurological and metabolic research models, with specific in vitro studies demonstrating its effects on neurotransmitter regulation.
  • Research models have employed various cellular and rodent systems to assess its impact on monoaminergic transmission and related behavioral outcomes.

Technical Properties

Tesofensine is soluble in DMSO at concentrations exceeding 10mg/mL and requires careful control of solubility conditions during reconstitution. For research purposes, it should be stored as a lyophilized powder in a desiccated environment to ensure stability. Reconstituted solutions are stable for short periods at low temperatures.
