摘要:
A 6-fluoroprostaglandin having the formula: ##STR1## wherein A is a carbonyl group or a hydroxymethylene group, R.sup.1 is a substituted or unsubstituted C.sub.1 -C.sub.10 alkyl group or a substituted or unsubstituted 5- or 6-membered cycloalkyl group, R.sup.2 is a hydrogen atom or a C.sub.1 -C.sub.10 alkyl group, each of R.sup.3 and R.sup.4 which may be the same or different is a hydrogen atom or a protecting group, R.sup.5 is a hydrogen atom or a hydroxyl group, and is a single bond or a double bond, and its salt when R.sup.2 is a hydrogen atom.
摘要:
A novel prostaglandin I.sub.2 derivative selected from a prostaglandin I.sub.2 having a halogen atom on the carbon atom corresponding to the 7-position of natural prostaglandin I.sub.2 and having a cycloalkylene group in the .alpha.-chain, and its esters and salts.
摘要:
An isoindazole compound of the formula (1) or a salt thereof; a method for the production thereof; and pharmaceutical use of the compound and a salt thereof, particularly as an angiotensin II antagonist and as an agent for the prophylaxis and treatment of circulatory diseases (particularly hypertension and heart failure); ##STR1## wherein Q is a heterocyclic derivative of the formula (2) or (3) ##STR2## wherein other symbols of the above formulas are as defined in the Specification. The compound and its salt show superior angiotensin II antagonism and are low toxic. Accordingly, they are useful as angiotensin II antagonists for the treatment or prophylaxis of angiotensin II-mediated diseases such as circulatory diseases of hypertension (e.g. essential hypertension, renal hypertension) and heart failure.
摘要:
A quinoline compound represented by the formula (1) or a salt thereof: ##STR1## wherein the definition of each substituents are described in the specification, which have angiotensin II antagonism and hypotensive action and are useful as an agent for the prevention and treatment of cardiovascular system diseases such as hypertension, heart failure and the like.
摘要:
An emulsion of lipid containing a prostaglandin analogue of the formula (1): ##STR1## wherein R.sup.1 is an alkanoyl group, R.sup.2 is a hydrogen atom or an alkyl group, each of R.sup.3 and R.sup.4 is a hydrogen atom or a protective group for an alcohol, R.sup.5 is an alkyl group which may have a substituent, and is a single bond or a double bond.
摘要:
Quinolin-2-yl benzoic acid compounds which are useful as intermediates of quinoline compounds having angiotensin II antagonist activity prepared by decarboxylating 2-(carboxyphenyl)-4-quinolinecarboxylic acid compounds in which a carboxyl group bonded to a phenyl group may be esterified, while a carboxyl group bonded to a quinoline ring is not esterified, and both rings may have one or more substituents inert to the decarboxylation reaction.
