Description

Description:

Tirzepatide (LY3298176) is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that is being developed for the treatment of type 2 diabetes. Tirzepatide (LY3298176) shows significantly better efficacy with regard to glucose control and weight loss than do Dulaglutide.

Tirzepatide, also known as LY 3298176, is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Tirzepatide has a greater affinity to GIP receptors than to GLP-1 receptors, and this dual agonist behavior has been shown to produce greater reductions of hyperglycemia compared to a selective GLP-1 receptor agonist. Signaling studies reported that tirzepatide mimics the actions of natural GIP at the GIP receptor. Tirzepatide was approved for improving blood sugar control in adults with type 2 diabetes, as an addition to diet and exercise.

FAQ

1. How to make an order?
Send me message and let me know what you need with quantity , then i will calculate to you

2. What's the lead time and shipping ways?
We will delivery to the package by USPS, FEDEX, DHL paket and YANWEN express to you after receive your payment, it would take around 5-15 days to your address.

3. How do i keep the peptides when i receive it ?
Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.

4. What's the payment methods ?
We could accept pay through paypal,bank transfer, XTransfer and bitcoin.

ECHEMI Editorial Reference

3,3',5-Triiodo-L-thyronine is a potent agonist of thyroid hormone receptors TRα and TRβ with Kis of 2.3 nM.
Crystalline T3 (liothyronine sodium, Cytomel) has a rapid onset and short duration of action. It is the therapy of choice when it is desirable to have rapid onset or cessation of activity, such as in patients with heart disease.
Off-White Solid
ChEBI: An iodothyronine compound having iodo substituents at the 3-, 3'- and 5-positions. Although some is produced in the thyroid, most of the 3,3',5-triiodo-L-thyronine in the body is generated by mono-deiodination of L-thyroxi e in the peripheral tissues. Its metabolic activity is about 3 to 5 times that of L-thyroxine. The sodium salt is used in the treatment of hypothyroidism.
Likely impurities are as in thyroxine. Purify it by dissolving in dilute NH3 at ~20o, then crystallise it by addition of dilute acetic acid to pH 6. Alternatively 35g are purified by dissolving it in a mixture of EtOH (250mL) and 2N NaOH (100mL), then hot 2N HCl is added to the boiling solution until the pH is 4-5. After cooling for a few hours, the solid is filtered off and dried in a vacuum [m 233-235o(dec)]. [Chambers et al. J Chem Soc 2433 1949, Beilstein 14 III 1566, 14 IV 2373.]

Research

Class:

Actin-sequestering protein / 43-amino-acid peptide

Status:

Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:

A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:

Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
