Problems solved by technology

The etiology and pathogenesis of AD are complex, involving multiple factors such as genetics, immunity, infection, environment, and spirit, and are closely related to the impairment of the skin barrier function. Its treatment is one of the most difficult problems in clinical practice. Therefore, the research and development of effective drugs for the treatment of atopic dermatitis is particularly urgent

Embodiment 1

[0021] 1.1 Experimental animals and reagents

[0022] Experimental animals: 72 clean-grade healthy female Kunming mice, weighing 18-22 g, were purchased from the Experimental Animal Center of Nanchang University.

[0023] Reagent: Azamycin F 5a , Azamycin F 4a and azamycin F 3a Streptomyces Streptomyces hygroscopicus var .azalomyceticus , according to literature [2] Methods: The strains were fermented, and the fermentation products were prepared by solvent extraction, silica gel column chromatography and semi-preparative HPLC. The purity was 98.2%, 97.8% and 97.2%, respectively, and prepared with 0.15% CMC-Na aqueous solution before the experiment; 2, 4 - Dinitrofluorobenzene (DNFB) was purchased from Shanghai Chemical Reagent Company; mouse IL-4 and IgE ELISA kits were purchased from Invitrogen Company.

[0024] Establishment of atopic dermatitis model mice

[0025] 72 Kunming mice were randomly divided into model group, normal control group, azamycin F 5a group,...

Embodiment 2

[0058] 2.1 Experimental animals and reagents

[0059] Experimental animals: 91 clean-grade healthy female Kunming mice, weighing 18-22 g, were purchased from the Experimental Animal Center of Nanchang University.

[0060] Reagent: Azamycin F pure fractions A, B, C and D produced by Streptomyces Streptomyces hygroscopicus var .azalomyceticus , according to literature [2] The method is to carry out strain fermentation, and the fermentation product is obtained by solvent extraction and silica gel column chromatography; through HPLC analysis and determination, azamycin F in group A of azamycin F 3a , F 4a and F 5a The contents of Azamycin F in Group B were 61.7%, 33.5%, and 4.3%. 3a , F 4a and F 5a The contents of Azamycin F in group C were 13.5%, 73.2%, and 12.7%, respectively. 3a , F 4a and F 5a The contents of Azamycin F in Group D were 1.3%, 10.2%, and 87.8%. 4a and F 5a The contents of 2.9% and 96.7% were prepared with 0.15% CMC-Na aqueous solution before the ex...

Abstract

The invention discloses application of azalomycin F to the preparation of medicines for treating atopic dermatitis. Proved by experiments, the azalomycin F can obviously decrease the concentrations of IL-4 (Interleukin-4) and Ig E (Immunoglobulin E) in the serum of a model mouse suffering from the atopic dermatitis caused by DNFB (Dinitrofluorobenzene), inhibit the ear swelling of the mouse suffering from the atopic dermatitis and decrease the thymus index and the spleen index of the mouse, obviously improves the skin-lesion symptom of the mouse, and further presents the effect of being capable of radically treating the atopic dermatitis, thereby showing that the azalomycin F has an obvious anti-atopic-dermatitis function; the azalomycin F can be used for preparing the medicines for treating the atopic dermatitis; the favorable application and development prospect of the azalomycin F are shown.

Description

technical field [0001] The invention relates to the application of azalomycin F (Azalomycin F) in the preparation of medicines for treating atopic dermatitis. Background technique [0002] Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disease, the main clinical manifestations are recurrent skin inflammation and itching. The etiology and pathogenesis of AD are complex, involving multiple factors such as genetics, immunity, infection, environment, and spirit, and are closely related to the impairment of the skin barrier function. Its treatment is one of the most difficult problems in clinical practice. Therefore, the research and development of effective drugs for the treatment of atopic dermatitis is particularly urgent. [0003] Azamycin F is a 36-membered polyhydroxy macrolide compound, including 3 main components Azamycin F 5a , F 4a and F 3a , has broad-spectrum anti-gram-positive bacteria and anti-fungal effects, and can be fermented by a variety of...
