摘要:
A link between ApoE4 allele and sirtuins expression level is identified that is believed to be associated with elevated risk for the promotion of processing of amyloid precursor protein (APP) by the non-amyloidogenic pathway in a mammal leading to elevated risk for Alzheimer's disease. Compounds are identified that upregulate sirtuins ( e.g. , SirT1) expression levels and appear to be useful in the treatment and/or prophylaxis of MCI and/or Alzheimer's disease.

摘要:
The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula Al , X1 , wherein A1 represents a cation and X1 représents an anion.
摘要:
A method for modifying at least one non-ester-containing parent compound, and the compounds produced using such method, which compounds are deployed to temporarily incapacitate at least one subject are disclosed. The modified compounds are rapidly metabolized to inactive and non-toxic metabolites when exposure to the modified compounds is halted. One or more of a predetermined chemical arrangement is incorporated into the parent compound having the formula (I): Phi-R-X-R'; where Phi is a phenyl, substituted aryl or heteroaryl system present in the parent compound or is 10 added to the parent compound; R is an alkyl or alkene containing chain either branched or unbranched from 0 to 10 carbons present in the parent compound or is added to Phi; X is a carboxyl, sulfoxyl or phosphatyl function added to R; and, R' is an alkyl, alkenyl or aralkyl group either branched or unbranched containing from 1 to 10 carbons is added to X in a metabolically 15 labile manner, or is a structural element already present as an inherent portion of the parent compound that is connected to X in a metabolically labile manner.

摘要:
This invention relates to novel homotopic prodrugs and medicaments and methods for their preparation, testing and use. In one embodiment, the homotopic prodrug has the general formula (I) wherein (II) is a biologically-active moiety comprising a carboxylic acid functional group, and Rb is a homotopically-symmetrical alcohol bonded to the biologically-active moiety through the carboxylic acid functional group to form an ester linkage, as well as optical isomers, enantiomers, pharmaceutically acceptable salts, biohydrolyzable amides, esters, and imides thereof and combinations thereof.
摘要:
Compounds or their salts of general formula (I): A-(B) wherein A = R-T1-, wherein R is the drug radical and T1 = (CO)t or (X)t', wherein X = O, S, NR1C, R1C is H or an alkyl having from 1 to 5 carbon atoms, or a free valence, t and t' are integers and equal to zero or 1, with the proviso that t = 1 when t' = 0; t = 0 when t' = 1; B = -TB-X2 wherein TB = (CO) when t = 0, TB = X when t' = -, X being as above defined; X2, monovalent radical, is such that the precursor drug of A and the precursor of B respectively meet the pharmacological tests described in the application.
摘要:
There are described liposomogenic UV absorbers, comprising a hydrophilic head group (=Z), a spacer (=W), a UV chromophore (Q) having an absorption in the range from 285 to 400 nm and at least one hydrophobic tail group (=A) of the formula (1), in which A1 and A2, independently of one another, are a hydrophobic radical, Q is a UV chromophore, W is an organic radical, Z1 and Z2, independently of one another, are a hydrophilic radical, n1 and n2, independently of one another, are a number from 0 to 4, n1=n2=0 not being additionally included, p is 1 or 2, q is a number from 0 to 3, r1 is 1 or 2, r2 is 0 or 1, and s1 is a number from 1 to 3. The liposomogenic UV absorbers according to the invention are preferably used as sunscreen agents in cosmetic preparations. They are capable of self-organization into bimolecular layers, and can thereby penetrate into the stratum corneum to a high extent and behave there in an extremely wash-resistant manner.
