Compounds of formula (I): ##STR1## (wherein n is 0 or 1, R.sup.1 and R.sup.2 are hydrogen or alkyl, one of A.sup.1 and A.sup.2 is --Z--Y and the other is --W--COOH, where W and Z are alkenylene or alkylene and Y is imidazolyl or pyridyl, and the broken lines represent two single bonds or one single bond and one double bond) and their salts, esters and amides have the ability to inhibit the synthesis of thromboxane A.sub.2 and hence are useful in the treatment or prophylaxis of thrombotic conditions. They may be prepared by introducing an imidazolyl or pyridyl group into the corresponding compound in which Y is replaced by an active group or atom.

摘要:
A method of treating a PAF-mediated pathology or for treating or preventing psoriasis, nephritis, asthma, inflammation or shock by administering an effective amount of a PAF antagonist of the formula ##STR1## wherein R.sup.1 and R.sup.2 are each --R.sup.5, --CH.dbd.CH--R.sup.5 or --C.tbd.C--R.sup.5 ; R.sup.5 is an unsubstituted or substituted C.sub.6 -C.sub.14 carbocyclic aryl of an aromatic heterocyclic having from 5 to 14 ring atoms, of which from 1 to 5 are hetero-atoms selected from the group consisting of nitrogen, oxygen and sulfur, the heterocyclic group being unsubstituted or substituted; R.sup.3 is hydrogen, a C.sub.1 -C.sub.6 alkyl, cyano, or --R.sup.5 ; X is oxygen or sulfur; A is a 1,4-piperazin-1,4-diyl or a 1,4-homopiperazin-1,4-diyl; B is a C.sub.1 -C.sub.6 alkylene, carbonyl, thiocarbonyl, sulfinyl or sulfonyl; and R.sup.4 is an unsubstituted or substituted phenyl group.
摘要:
Glycerol derivatives having at least one heterocyclic group on the 1 or 2 position are PAF antagonists which may be used to treat asthma, inflammation and shock.
摘要:
This invention relates to a mammalian artificial chromosome vector, which retains a human chromosome 7 fragment comprising human cytochrome P450 genes and is transmittable to progeny, wherein the human chromosome 7 fragment retains a region of approximately 1 Mb±500 Kb in size comprising at least a human CYP3A gene cluster, which region is located between chromosome markers AC004922 and AC073842, and to a non-human mammalian animal retaining the vector.
摘要:
The invention relates to pharmaceutical compositions comprising gastrointestinal proliferative factor (GIPF) polynucleotides and polypeptides. The invention further relates to the therapeutic use of GIPF to prevent or treat conditions or disorders associated with the degeneration of the epithelial mucosa.
摘要:
In order to control volatilization or release of organic solvent, especially formaldehyde, and to adsorb them, and at the same time, to improve weather resistance, water resistance, stain resistance and fungus resistance, natural paint is composed of vegetable drying oil, haze wax, candelilla wax and carnauba wax as the main components, and contains at least one or more of rosin, silk powder and component of rice bran.

Compounds of formula (I): ##STR1## wherein R.sup.1 and R.sup.2 is each --R.sup.5, --CH.dbd.CH--R.sup.5 or --C.tbd.C--R.sup.5, wherein R.sup.5 is optionally substituted aryl or aromatic heterocyclic; R.sup.3 is hydrogen, alkyl, cyano or --R.sup.5 ; X is oxygen or sulfur; A a 1,4-homopiperazin-1,4-diyl; B' is alkylene, carbonyl, thiocarbonyl, sulfinyl or sulfonyl; and R.sup.4 is optionally substituted phenyl and pharmaceutically acceptable salts thereof have valuable PAF antagonist activity, and may be prepared by reacting a compound containing the homopiperazine part of the molecule with a compound containing the other part of the molecule.
摘要:
Prostaglandin derivatives, and specifically derivatives of isocarbacyclin, have an optionally substituted methylene group as a substituent on the .alpha.-carbon atom of the .alpha.-side chain. They have a variety of physiological effects, notably a strong ability to inhibit blood platelet aggregation and a strong anti-ulcer activity.
