The invention relates to novel compounds which correspond to general formula (I) below: and also to the method for preparing them, and to their use in pharmaceutical compositions for use in human or veterinary medicine, in particular in dermatology, and also in the field of cardiovascular diseases, immune diseases and/or diseases related to lipid metabolism, or alternatively in cosmetic compositions.
摘要:
The present invention relates to crystalline 1-adamantanamine salts, and polymorphic forms thereof, of prostaglandin analog intermediates of formula 3a, 4a and 6a, useful in the preparation of Tafluprost and Lubiprostone and processes for their preparation.
摘要:
The present invention is directed to a method for the prophylactic and therapeutic treatment of diabetic retinopathy. The method involves the administration of an inhibitor of formulae (I), (II) and (III) of the branch chain amino acid-dependent aminotransferase (BCAT) pathway to an animal, such as a mammal, in particular a human, in an amount sufficient to treat the retina for diabetic retinopathy prophylactically or therapeutically. The present invention is also directed to several novel inhibitors of formula (IV) of the BCAT pathway. In formulae (I-IV), n, m, X and R1-R13 have the meanings given in the description.
摘要:
Compound of formula (I) wherein the dotted line is no bond or the dotted line together with the carbon-carbon bond represents a double bond; X and Y represent independently carbonyl, -CH 2 -, -CHMe-, or -C(Me) 2 -; and n and m are independently 0 or 1; with the proviso that if X is carbonyl either or both of n or m is 0, and their use as malodor counteractant. Furthermore, a process of their production and consumer products comprising them is described.
摘要:
The present invention relates to diterpene derivatives prepared from the components which are extracted from Acanthopanax Koreanum and represented by Chemical Formula (1).

摘要:
The present invention describes methods for the diagnosis and differential diagnosis of the different forms of multiple sclerosis The methods measure the intensities of specific small molecules called metabolites in samples from patients with clinically diagnosed relapsmg-remittmg or primary-progressive forms of multiple sclerosis and compare these intensities to the intensities observed in a population of healthy individuals, thus identifying markers of multiple sclerosis A method is also provided for the differential diagnosis of subjects afflicted with relapsing- renitting multiple sclerosis from secondary-progressive multiple sclerosis.
