MSDS Information

Melanotan II Usage And Synthesis

Description

Melanotan II is a synthetic analogue of the melanocortin peptide hormone alpha-melanocyte stimulating hormone (α-MSH) that occurs naturally. In usage, Melanotan II has been revealed to have aphrodisiac and melanogenesis (tanning) effects that have been subjected to clinical trials and preliminary studies. The compound is a cyclic lactam analogue of α-MSH that has an amino sequence named MTII (Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-NH2). Notably, no government drug regulatory agency across the world had approved for the use of any compound incorporating the Melanotan II peptide by 2010

First aid measures

If inhaled

Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.

Following skin contact

ECHEMI Editorial Reference

Thymalfasin is an immunomodulating agent able to enhance the Thl immune response. Sequence: N-acetyl-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn.
Thymalfasin is a polypeptide.|Thymalfasin is a synthetic analogue of thymosin-alpha-1, a 28-amino acid protein derived from the precursor protein prothymosin-alpha. Exhibiting a variety of immunoregulating properties, thymosin-alpha-1 induces differentiation of murine T-cell precursors and human thymocytes and the terminal differentiation of functionally immature cord blood lymphocytes and induces production of IL-2, high affinity IL-2 receptors, and B-cell growth factors by peripheral blood mononuclear cells. T-helper and cytotoxic/suppressor T-cell populations are targets of thymosin activity. Thymosin-alpha-1 has been shown to increase the efficiency of antigen presentation by macrophages and to be an endogenous modulator of alpha-thrombin activity. (NCI04)|A thymus hormone polypeptide found in thymosin fraction 5 (a crude thymus gland extract) but now produced by synthesis. It is used alone or with interferon as an immunomodulator for the treatment of CHRONIC HEPATITIS B and HEPATITIS C. Thymalfasin is also used for the treatment of chemotherapy-induced immunosuppression, and to enhance the efficacy of influenza and hepatitis B vaccines in immunocompromised patients.

Research

Class:

Synthetic cyclic heptapeptide / non-selective melanocortin receptor agonist

Status:

Research compound — NOT FDA approved. FDA issued warning letters. WADA banned substance.

Mechanism:

A synthetic cyclic heptapeptide (Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH₂) analog of α-MSH. Melanotan II is a high-affinity non-selective agonist at MC1R, MC3R, MC4R, and MC5R. MC1R activation induces melanogenesis (skin darkening/tanning); MC4R activation affects sexual function, appetite suppression, and energy homeostasis. Carries significant safety risks including nausea, hypertension, and priapism.
