PHARMACEUTICAL COMPOSITION FOR PREVENTING OR TREATING IMMUNE DISEASES OR INFLAMMATORY DISEASES, CONTAINING BIGUANIDE DERIVATIVE COMPOUND AS ACTIVE INGREDIENT
The present invention relates to a biguanide derivative compound capable of effectively preventing and treating immune diseases. The biguanide-based derivative compound according to the present invention inhibits the generation of IL-17 and TNF-α, which are inflammatory cytokines, increases the activity of regulatory T cells having an immunomodulatory function, and exhibits excellent therapeutic effects in animal models of immune diseases. Accordingly, the biguanide-based derivative compound can be usefully used as an immunosuppressant or a pharmaceutical composition capable of preventing or treating various immune diseases, such as autoimmune diseases, inflammatory diseases, and transplant rejection, caused by the dysregulation of immune responses.
HIGHLY LOADED METAL OXIDE MATERIALS BY SELF-ASSEMBLY FOR EXTENDED BIOLOGICALLY ACTIVE MOLECULE RELEASE IN MEDICAL AND DENTAL APPLICATIONS
A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

COMPOSITIONS AND METHODS FOR THE TREATMENT OF NEUROLOGICAL DISEASES AND DISORDERS
In certain embodiments allosteric inhibitors of BACE are provided. Illustrative inhibitors include but are not limited to various metformin analogs.
Metformin glycinate for blood glucose control
The present invention relates to metformin glycinate salt and pharmaceutical compositions thereof for the treatment of diabetes mellitus. The method includes administration of the metformin glycinate salt by various routes selected from oral, intravenous injectable, intramuscular injectable, nasal, intraperitoneal, or sublingual, in order to achieve a reduction in blood glucose levels. The invention further relates to the synthesis of a new 1,1-dimethylbiguanide glycinate salt, called Metformin Glycinate. The resulting salt exhibits advantages over other metformin salts. These advantages are due, in the first place, to the fact that the glycine counterion exhibits hypoglycemic effects by itself. Moreover, the salt exhibits more rapid absorption, reaching higher plasma concentrations than those produced with metformin hydrochloride.
