Abstract:
3,4-Dihydroisoquinoline derivative compounds represented by the following general formula (I) (wherein each symbol has the meaning as specified in the description) or nontoxic salts thereof. Because of having a CB2 receptor agonist activity, the compounds represented by the general formula (I) are useful in preventing and/or treating various diseases, for example, asthma, nasal allergy, atopic dermatitis, autoimmune diseases, rheumatish, immnodeficiency, postoperative pain and carcinomatous pain.
Abstract:
The use of a compound of the formula (I) and isomers, salts, solvates, chemically protected forms, and prodrugs thereof, in the preparation of a medicament for inhibiting the activity of PARP, wherein A and B together represent an optionally substituted, fused aromatic ring, the dotted line between the 3 and 4 positions indicates the optional presence of a double bond, at least one of RC1 and RC2 is independently represented by -L-RL, and if one of RC1 and RC2 is not represented by -L-RL, then that group is H, where L is of formula: -(CH2)¿n1¿-Q¿n2?-(CH2)n3-wherein n1, n2 and n3 are each selected from 0, 1, 2 and 3, the sum of n1, n2 and n3 is 1, 2 or 3 and each Q (if n2 is greater than 1) is selected from O, S, NR3, C(=O), or -CR1R2-, where R1 and R2 are independently selected from hydrogen, halogen or optionally substituted C1-7 alkyl, or may together with the carbon atom to which they are attached form a C3-7 cyclic alkyl group, which may be saturated (a C3-7 cycloalkyl group) or unsaturated (a C3-7 cycloalkenyl group), or one of R1 and R2 may be attached to an atom in RL to form an unsaturated C3-7 cycloalkenyl group which comprises the carbon atoms to which R1 and R2 are attached in Q, -(CH2)n3- (if present) and part of RL, and where R3 is selected from H or C1-7 alkyl, and RL is selected from optionally substituted C3-20 heterocyclyl, C5-20 aryl and carbonyl, and RN is selected from hydrogen, optionally substituted C1-7 alkyl, C3-20 heterocyclyl, C5-20 aryl, hydroxy, ether, nitro, amino, thioether, sulfoxide and sulfone.
Abstract:
A reporter system reflecting the transport process of GPI anchor protein to cell wall is constructed and a compound inhibiting this process is found out. Further, a gene imparting tolerance to the above compound is identified and a method of screening a compound inhibiting the activity of the protein encoded by this gene is developed. Thus, it is clarified by the novel compound that antifungal agents depending on a novel mechanism, wherein the transport process of GPI anchor protein to cell wall is inhibited, are available.
Abstract:
The invention relates to novel acetamide derivatives of formula (I) and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of such compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as orexin receptor antagonists.
Abstract:
Compounds which are highly potent and highly specific β3-Adrenoreceptor agonists are provided. The compounds are formulated into pharmaceutical preparations and administered for stimulating, regulating and modulating metabolism of fats in adipose tissues in animals, particularly humans and other mammals. The compounds of the invention have the structure (A). R1 and R2 are each independently members selected from the group consisting of H, OH, C1, NO2, CH3SO2NH, NH2, CH3O and weak acids of the structure R7-NH, where R7 is an acyl group, wherein at least one of R1 and R2 is OH. It is generally preferred that R2 be OH; R3, R4 and R5 are variously and independently members selected from I, Br, C1, F, OCH3, CH3, alkyl, alkylaryl, aminoalkyl, thioalkyl, and O-alkyl. Preferably, R4 and R5 are each a halogen, the same or different; R6 is an acid moiety which forms an acid salt with the NH group. R6 is desirably HC1 or (COOH)2. While the racemic mixtures are active, selective, and bioavailable, we have found that the isolated isomers are ordinarily of more particular interest. The S(-) isomers are preferred, as they will be found to have the highest selectivity and the highest bioavailability. The R(+) isomers are also of interest, as the R-isomers are in some cases easier to isolate. The compounds are formulated into pharmaceutical carriers to serve as highly selective, effective and safe β3-Adrenoreceptor agonists to provide long term weight control. In humans, the compositions are administered to control body fat levels, and to maintain acceptable body fat levels over time. In domesticated animals, the compositions are administered to attain desirably low fat content in carcass meats intended for human consumption.
