Sequence-specific 1H, 15N and 13C resonance assignments of Art v 1: a proline-rich allergen of Artemisia vulgaris pollen

Art v 1 is the major allergen of mugwort (Artemisia vulgaris) pollen, a significant cause of hay fever all over Europe. Specific immunotherapy is the only treatment modality for allergic disease. Application of modified allergens makes the treatment safer and more efficient. In this work, two out of three (citraconic anhydride, cis-aconitic anhydride, 2,3-dimethylmaleic anhydride) tested anhydrides were proven to be suitable for chemical modifications of allergens. Art v 1 was modified by cis-aconitylation and citraconylation in order to obtain derivatives of Art v 1 that may be suitable for further immunological testing. Acylation of Art v 1 gave derivatives (caaArt v 1 and citArt v 1) with about 80 % modified amino groups. The derivatives were in the monomeric form and had dramatically reduced pI values. Both derivatives were relatively stable at neutral pH values, while the acyl groups undergo hydrolysis under acidic conditions. Modification of allergens by cis-aconitylation and citraconylation could be a new tool for obtaining allergoids.

New Treatments

Diseases mediated by the immune system are difficult problems to treat such as human immunodeficiency virus (HIV) and other lethal viruses. Infections that occur in normal people are generally brief and rarely leave permanent damage. Treatment of this disease requires an aggressive and innovative approach to the development of new treatments so that it requires the role of immunomodulators to improve the immune system. A substance that acts as an enhancer or immune enhancer can be obtained by using herbs that are efficacious as immunostimulants. One of the herbs used is herbal binara (Artemisia vulgaris L) which has been studied as a potential immunomodulator with high antioxidant activity. Previous research also stated that red shoots (Syzygium oleana) were studied as potential immunomodulators with high antioxidant activity. Several other species such as Syzygium samarangense have 16 flavonoida compounds which show pharmacological immunological activity. The purpose of this study was to determine the content of secondary metabolites of ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) and to determine the best dose of extract from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) can reduce the volume of swelling of mouse feet. Examination of the chemical content of secondary metabolites from the ethanol extract of herbal binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) is carried out by chemical screening and characterization of simplicia and extract. The method used is the slow type hypersensitivity method. In this test the independent variable is the secondary metabolite of ethanol extract of herb binara (Artemisia vulgaris L.) with red shoots (Syzygium oleana) with four concentrations (50, 100, 200 and 400 mg / kgBB). The positive control used by Stimuno dose is 32.5 mg / kgBB
