摘要:
A medicament having inhibitory activity against NF-κB activation which comprises as an active ingredient a substance selected from the group consisting of a compound represented by the following general formula (I) and a pharmacologically acceptable salt thereof, and a hydrate thereof and a solvate thereof: wherein X represents a connecting group whose number of atoms in a main chain is 2 to 5 (said connecting group may be substituted), “A” represents an acyl group which may be substituted, (provided that unsubstituted acetyl group and unsubstituted acryloyl group are excluded,) or a C1 to C6 alkyl group which may be substituted, or A may bind to connecting group X to form a cyclic structure which may be substituted, “E” represents an aryl group which may be substituted or a heteroaryl group which may be substituted, ring Z represents an arene which may have one or more substituents in addition to the group represented by formula —O-A wherein A has the same meaning as that defined above and the group represented by formula —X-E wherein each of X and E has the same meaning as that defined above, or a heteroarene which may have one or more substituents in addition to the group represented by formula —O-A wherein A has the same meaning as that defined above and the group represented by formula —X-E wherein each of X and E has the same meaning as that defined above.
摘要:
Novel cyclic ester-amides having the formula: ##STR1## where R is an alkyl group having from 2 to 5 carbon atoms, and x ranges from 2 to 6 by reacting a polyethylene glycol monoamine having the formula NH.sub.2 --(CH.sub.2 CH.sub.2 O).sub.x --H, where x is as above, with at least one dicarboxylic acid, where the dicarboxylic acid is selected from the group consisting of glutaric, adipic, pimelic acids and mixtures thereof. The a molar ratio of polyethylene glycol monoamine to dicarboxylic acid should be about 1:1. Catalysts may be optionally used, and may include such compounds as titanium alkoxides; and zinc, manganese and antimony salts of carboxylic acids. This method is anticipated to be a useful step in a new preparation of valuable cyclic products.
