Abstract:
Among other things, the present invention provides novel compounds capable of effectively inhibiting inflammatory responses that are mediated by G-proteins or GPCRs in neutrophils, macrophages and platelets. In particular, compounds of the present invention act as inhibitors of edema, inhibitors of erythema and inhibitors of MPO (myeloperoxidase), pharmaceutical compositions containing the same compounds and the use thereof for the treatment of diseases that may benefit from edema, erythema and MPO inhibition, such as inflammation (acute or chronic), asthma, autoimmune diseases, and chronic obstructive pulmonary disease (COPD) (e.g., emphysema, chronic bronchitis and small airways disease, etc.), inflammatory responses of the immune system, skin diseases (e.g., reducing acute skin irritation for patients suffering from rosacea, atopic dermatitis, seborrheic dermatitis, psoriasis), irritable bowel syndrome (e.g., Chron's disease and ulcerative colitis, etc.), and central nervous system disorders (e.g., Parkinson's disease).
Abstract:
The invention provides novel methods for selective targeting of chemical compounds to cells undergoing a death process, in particular apoptosis, and to platelets undergoing activation during blood coagulation. The invention further provides compounds to be used in said methods for medical practice, for diagnostic and therapeutic purposes.
Abstract:
Certain known and novel pyruvate derivatives are particularly active in restoring or preserving metabolic integrity in oxidatively competent cells that have been subjected to oxygen deprivation. These pyruvate-derived compounds include, but are not limited to oximes, amides, pyruvate analogues, modified pyruvate analogues, esters of pyruvate (e.g., polyol-pyruvate esters, pyruvate thioesters, glycerol-pyruvate esters and dihydroxyacetone-pyruvate esters). Such pyruvate derivatives (including single tautomers, single stereoisomers and mixtures of tautomers and/or stereoisomers, and the pharmaceutically acceptable salts thereof) are useful in the manufacture of pharmaceutical compositions for treating a number of conditions characterized by oxidative stress.

Abstract:
Inhibiteurs de métalloprotéases, leurs procédés de préparation et leurs utilisations thérapeutiques. La présente invention a pour objet de nouveaux composés α-vinyl carbonylés répondant à la formule générale (I) : dans laquelle R 1 , R 2 , R 3 , R 4 , R 5 et Y sont tels que définis à la revendication 1, leurs isomères, diastéréoisomères et sels d'addition à un acide ou une base pharmaceutiquement acceptable. L'invention concerne encore un procédé de préparation desdits composés (I). Elle concerne également l'utilisation desdits composés (I) comme inhibiteurs sélectifs de métalloprotéases, et notamment des métalloprotéases matricielles 12 (MMP-12) et/ou 9 (MMP-9). Les composés (I) seront ainsi particulièrement utiles pour prévenir et/ou traiter la broncho-pneumopathie chronique obstructive (BPCO), en particulier l'emphysème induit par la fumée de cigarettes.
Abstract:
On one hand, the present invention relates to cosmetic compositions comprising poly(lactic glycolic) acid (PLGA) nanoparticles for applica¬ tions to the skin. On the other hand, it also concerns polymeric nanoparticles having on its surface a plurality of cosmetically active agents, each of said agents being associated to said nanoparticle via oleylcysteineamide, delivery systems for topical application based on said particles and cosmetic formulations comprising said particles.

Abstract:
The invention relates generally to optical agents for biomedical applications, including phototherapy. Azide derivatives of some embodiments have an azido group that is directly attached to a phenyl ring having a combination of electron donating groups and electron withdrawing groups. Optical agents of the invention include phototherapeutic agents, including Type 1 phototherapeutic agents that enable a versatile phototherapy platform for treatment of a range of pathological conditions, including the treatment of cancers, stensosis and inflammation. The invention further provides preparations and formulations comprising azide derivatives and related methods of making and using azide optical agents in in vivo or ex vivo biomedical procedures.
