The present invention provides a composition comprising an effective amount of benfotiamine and an effective amount of pyridoxamine in a suitable vehicle for topical application. The present compositions are useful in improving the appearance of aged skin characterized by wrinkles, loss of elasticity, and hyperpigmentation caused by chronoaging and/or photoaging of skin, by inhibiting particularly skin damage resulting from reactive carbonyl species (RCS), glycation of skin proteins, formation of advanced glycation endproducts (AGEs) and formation of advanced lipoxidation endproducts (ALEs).

This invention provides a method for treating a subject either during or soon after a seizure, in order to reduce the extent of neuronal damage in the subject resulting from the seizure comprising administering to the subject, either during or soon after the seizure, a therapeutically effective amount of an inhibitor of receptor for advanced glycation endproducts (RAGE), so as to thereby reduce the extent of neuronal damage in the subject. This invention further provides a method for inhibiting neuronal damage which would otherwise result from a seizure in a subject predisposed to having a seizure, comprising administering to the subject a prophylactically effective amount of an inhibitor of receptor for advanced glycation endproducts (RAGE), so as to inhibit neuronal damage which would otherwise result from a seizure in the event the subject were to suffer a seizure.

A method of treating Alzheimer's disease, Parkinson's disease, sexual dysfunction or erectile dysfunction in a man by administration of a 5alpha reductase inhibitor together with a testosterone supplement is described. The method is also concerned with the use of the 5alpha reductase inhibiting compound and the testosterone supplement together with another agent useful for treating erectile dysfunction, including PDE V inhibitors; AGE (advanced glycation end-product) breakers; alpha 1 blockers; alpha 1A antagonists; alpha 2 antagonists; dopamine agonists; dopamine D4 agonists; melanocortin agonists; oxytocin agonists; prostaglandin; radical scavengers; rotamase inhibitors; aviptadil; nitroglycerine; and GPCR agonists for treating male sexual dysfunction or erectile dysfunction.

The present invention provides a method for treating symptoms of diabetes in a diabetic subject which comprises administering to the subject a therapeutically effective amount of an agent which inhibits binding of advanced glycation endproducts to any receptor for advanced glycation endproducts so as to treat chronic symptoms of diabetes in the subject.

This invention relates to methods for lowering lipid levels in mammals using compounds that inhibit advanced glycation endproducts (AGEs), LR-9, LR-74 and LR-90. These compounds, which inhibit non-enzymatic protein glycation, also inhibit the formation of advanced lipoxidation endproducts (ALEs) on target proteins by trapping intermediates in glycoxidation and lopoxidation and inhibiting oxidation reactions important in the formation of AGEs and ALEs.

Disclosed herein are a leaf and stem extract of Aster koraiensis, a root extract of Aster koraiensis, a flower extract of Aster koraiensis, a pharmaceutical composition for the prevention or treatment of diabetic complications, a health functional food for the improvement of diabetic complications, and a pharmaceutical composition and health functional food for the prevention or delay of aging, in which each of the compositions and the foods contain, as an active ingredient, at least one of the Aster koraiensis extracts. Each of the extracts is obtained by drying and finely cutting each of the leaf and stem part, root and flower of Aster koraiensis, extracting the cut plant with alcohol or aqueous alcohol solution, filtering the extracted solution and concentrating the filtrate under reduced pressure. Also disclosed are a pharmaceutical composition for the prevention or treatment of diabetic complications, a health functional food for the improvement of diabetic complications, and a pharmaceutical composition and health functional food for the prevention or delay of aging, which contain, as an active ingredient, at least one of fractions obtained by fractionating each of the Aster koraiensis extracts in the order of hexane, ethyl acetate, n-butanol and water fractions. The leaf and stem extract of Aster koraiensis, the root extract of Aster koraiensis and the flower extract of Aster koraiensis have the effect of inhibiting the production of advanced glycation endproducts (AGEs), the causes of diabetic complications, and effectively inhibit aldose reductase (AR) activity. Thus, the disclosed extracts will be highly useful for the prevention or treatment of diabetic complications and the prevention of aging.

Pentoxifylline, pioglitazone and metformin have been found to inhibit the nonenzymatic glycation of proteins which often results in formation of advanced glycation endproducts and crosslinks. The nonenzymatic glycation and crosslinking of proteins is a part of the aging process with the glycation endproducts and crosslinking of long-lived proteins increasing with age. This process is increased at elevated concentrations of reducing sugars in the blood and in the intracellular environment such as occurs with diabetes. The structural and functional integrity of the affected molecules become perturbed by these modifications and can result in severe consequences. The compounds of the present invention can be used to inhibit this process of nonenzymatic glycation and therefore to inhibit some of the ill effects caused by diabetes or by aging. The compounds are also useful for preventing premature aging, rheumatoid arthritis, Alzheimer's disease, uremia, neurotoxicity, atherosclerosis and spoilage of proteins in food and can prevent discoloration of teeth.

The invention provides a new medical application of ritonavir and in particular relates to an application of the ritonavir for preventing or treating Acute Lung Injury/Acute Respiratory Distress Syndrome (ALI/ARDS) and pulmonary fibrosis in such a manner of inhibiting the occurrence and development of the ALI/ARDS and the pulmonary fibrosis by inhibiting the apoptosis of type I alveolar epithelial cells and promoting the expression of the Receptor For Advanced Glycation Endproducts (RAGE) of the type I alveolar epithelial cells. When in use, the oral administration dosage of the ritonavir ranges from 100mg to 6000mg, preferably, from 200mg to 3000mg.
