The present compositions are useful in improving the appearance of aged skin characterized by wrinkles and loss of elasticity. Preferred components include R-lipoic acid or R-dihydrolipoic acid, acetyl-l-carnitine, and l-carnosine.

The present invention relates to compounds of the formula (I) wherein X1 and X2 independently represent O, NH or S, R1 and R2 are independently selected from the group consisting of a C1-C30 hydrocarbyl group, an amino acid bonded via an amide bond or a peptide bonded via an amide bond each having up to 200 amino acids, the conjugated residue X1 or X2 in this case being NH, and hydrogen, both radicals R1 and R2 preferably not being H, wherein R3 is a residue selected from group consisting of —S—R6, wherein R6 is a C1-C30 hydrocarbyl group, at least one of R1 and R2 not being H when X1 and X2 are oxygen, —S—CH2—CH(NH2)(COOH) (cysteine-S-yl), a homologue or derivative (e.g. N-acetyl cysteine-S-yl) thereof, a peptide having up to 200 amino acids which contains at least one amino acid radical with a thiol group, preferably a cysteine radical, and is bonded via the thio sulfur, preferably via the cysteine sulfur (peptide-S-yl), coenzyme A which is bonded via a thiol group or fragments thereof, acyl carrier protein bonded via a thiol group, and dihydrolipoic acid bonded via a thiol group, and pharmaceutically acceptable salts thereof. The present invention also relates to the use of these compounds for preparing a drug and drugs containing the same.

Long term storage stable pemetrexed-containing liquid pharmaceutical compositions are disclosed. The compositions can include pemetrexed or pharmaceutically acceptable salts thereof; an antioxidant selected from lipoic acid, dihydrolipoic acid, methionine and mixtures thereof; a chelating agent selected from lactobionic acid, sodium citrate, tribasic and mixtures thereof; and a pharmaceutically acceptable fluid. The pH of the compositions is in a range of about 8 to about 9.5. The pemetrexed-containing compositions have less than about 5% total impurities, on a normalized peak area response (“PAR”) basis as determined by high performance liquid chromatography (“HPLC”) at a wavelength of 227 nm, after at least about 18 months of storage at a temperature of from about 5° C. to about 25° C. Methods of preparing the formulation as well as methods of treatment of pemetrexed-susceptible diseases using the same are also disclosed.

The present invention discloses a fluorescent gold nanocluster, comprising: a dihydrolipoic acid ligand (DHLA) on the surface thereof, wherein the fluorescent gold nanocluster generates fluorescence by the interaction between the dihydrolipoic acid ligand and the nanocluster and the particle diameter of the fluorescent gold nanocluster is between 0.5 nm and 3 nm, wherein the wavelength of the emission fluorescence of the fluorescent gold nanocluster is between 400 nm and 1000 nm. In addition, the fluorescent gold nanocluster is used as bioprobes and / or applied in fluorescent biological label, clinical image as contrast medium, clinical detection, clinical trace, and clinical treatment etc.

Disclosed herein is a method for treating an inflammatory disease in a subject, including administering to the subject a therapeutically effective amount of a dihydrolipoic acid (DHLA) coated gold nanocluster about 0.1 to 20 nm in diameter. Also disclosed is a method for reducing the expression of a pro-inflammatory molecule in a cultured cell, including contacting the cultured cell with the saidDHLA coated gold nanocluster. Still disclosed is a pharmaceutical composition that includes the present DHLA coated gold nanocluster. The pharmaceutical composition is useful for treating the inflammatory disease in the subject.

Formulations comprising docetaxel or a salt thereof in combination with α-lipoic acid and / or dihydrolipoic acid and / or salts thereof in narrow concentration ranges have improved stability as concentrate liquid formulations and permit longer times between dilution from higher concentrations through completion of infusions prepared therefrom allowing for lesser waste and more efficient use of personnel in infusion preparation.

A stabilized dihydrolipoic acid (DHLA) compound is provided. The stabilized DHLA is derived from a microbiological culture media including at least one live probiotic organism, R-lipoic acid and at least one nutritive agent. The stabilized DHLA may be prepared by dispersing the microbiological media in distilled water to form a broth, incubating the broth at a predetermined temperature for a select period of time to induce probiotic activity, adding organic ethanol to the broth to halt the probiotic activity, and separating the derived stabilized DHLA from the broth.
