Pimecrolimus Usage And Synthesis

Topical immunomodulators	Pimecrolimus is a topical immunomodulators and is a kind of semi-synthetic products of the Streptomyces-produced ascomycin. It has a greater lipophilicity than tacrolimus with a stronger affinity with the skin. It can effectively and safely control the signs and symptoms of facial seborrheic dermatitis and can quickly relieve the itching symptoms of patients with dermatitis and eczema as well as reduce the lesion area, clear atopic dermatitis (eczema) sign. Therefore, it is an effective treatment method for the treatment of atopic dermatitis (eczema) for both early remission purpose and long-term control purpose.  Seborrheic dermatitis is the body's immune inflammatory response to lipophilic Malassezia. Both the humoral and cellular immunity participate in the sickening process. Pimecrolimus can selectively inhibit the activation of T cell through inhibiting the activity of the calcium-dependent nerve transcription proteins which is indispensible for the activation of T cells and prevent the release of cytokines and pro-inflammatory mediator, and further exhibiting strong anti-inflammatory activity. These results suggest that the mechanism of pimecrolimus for treatment of seborrheic dermatitis comes from its anti-inflammatory effect and immune regulation. Currently there have been no reports regarding on its direct participation of antifungal activity. But in recent years, there have been reports finding that tacrolimus (a kind of immunomodulatory agents with similar chemical structure and mechanisms as pimecrolimus) have some anti-Malassezia activity.  Similar as the tacrolimus, pimecrolimus is a cellular selective inhibitor which is produced and released by the pro-inflammatory cytokine and can combine with macrophilin 12 (FKBP-12) to inhibit of calcium-dependent calcineurin as well as suppress the T-cell activation through blocking the early cytokines transcription of T cells. In particular, a level of nanogram is enough to suppress the synthesis of T cell IL-2 and IFN-γ (Th1 cell origin) factor and can also inhibit the synthesis of IL-4 and IL (Th2 cell-derived). In addition, in vitro experiments, pimecrolimus can also be applied to inhibit the antigen as well as IgE stimulated mast cells’ release of inflammatory cytokines and inflammatory mediators [4, 5]. Clinical data have shown that after topical application, the blood concentration is very low and is usually under the detected value (<0.5 ng/mL). It also has no drug accumulation phenomenon.  The above information is edited by the Chemicalbook of Dai Xiongfeng.
Chemical Properties	White Solid
Uses	Pimecrolimus is a semi-synthetic, macrocyclic lactone derived from ascomycin by activation of the 32-hydroxy group with a triflate ester, and nucleophilic substitution with chloride under phase transfer conditions to provide the chloro analogue. Pimecrolimus has been targeted for treatment of inflammatory skin disorders. Like all tacrolimus analogues, pimecrolimus binds to receptor protein, FKBP12. The complex then binds to mTOR preventing it from interacting with target proteins. Pimecrolimus is extensively cited in the literature with over 2,000 citations.
Uses	Macrolactam ascomycin derivative; inhibits production of pro-inflammatory cytokines by T cells and mast cells. Immunosuppresant
Uses	Pimecrolimus caused a strong and dose-dependent inhibition of anti-IgE–induced release of histamine from mast cells and basophils (maximally 73% and 82%, respectively, at 500 nmol/L pimecrolimus) and of mast cell tryptase (maximally 75%) and a less pronou
