摘要:
A chemical linking agent formed of a di- or higher functional photoactivatable compound and providing at least one group that is charged under the conditions of use in order to provide improved water solubility. The linking agent further provides two or more photoactivatable groups in order to allow the agent to be used as a cross-linking agent in aqueous systems. The charged group can be provided by a radical that includes one or more salts of organic acids, onium compounds, or protonated amines (and optionally one or more additional photoreactive group), and the photoreactive groups can be provided by two or more radicals that include an aryl ketone.
摘要:
4-Amino-5-oxy-2,6,6-trimethyl-2-cycloheptene compounds represented by general formula (I), pharmacologically acceptable salts thereof, or solvates of these wherein R?1 and R2¿ independently represent each hydrogen, optionally substituted alkyl or phenyl optionally having hydroxy, lower alkoxy, amino, nitro, carboxy, lower alkoxycarbonyl or halogeno on its ring, or R?1 and R2¿ together with the nitrogen atom may form a nitrogen-containing heterocycle; R3 represents hydrogen, lower alkyl or lower aliphatic acyl; and W represents oxo, oxime or oxime ether. The compounds exert effects on a rat peripheral embolism model, a spontaneously hypertensive rat and a histamine-induced airway constriction model, which indicates that they are useful as a remedy for hypertension, peripheral embolism or bronchial asthma.
摘要:
The present invention provides the new use in the treatment of amyloidosis with the anthracyclinone of formula (A) wherein R1, R2, R3, R4 and R5, are appropriate substituents. Some compounds of formula (A) are novel. Processes for their preparation and pharmaceutical composition containing them are also described.

These compounds are useful psychotherapeutics and are potent serotonin (5-HT1) agonists and antagonists and may be used in the treatment of depression, anxiety, eating disorders, obesity, drug abuse, cluster headache, migraine, pain and chronic paroxysmal hemicrania and headache associated with vascular disorders, and other disorders arising from deficient serotonergic neurotransmission. The compounds can also be used as centrally acting antihypertensives and vasodilators.
wherein Q represents an aryl group, a heterocyclic group, a diarylmethyl group, an aralkyl group composed of an aryl group and an alkylene group, an alkyl group or a cycloalkyl group, in which the aryl group, heterocyclic group, and the aryl moiety of the diarylmethyl group and aralkyl group may be substituted with one or more substituents; R represents a bicyclic, substituted, nitrogen-containing heterocyclic group or a substituted phenyl group, in which the nitrogen-containing heterocyclic group is composed of a 5-membered, substituted, aromatic or saturated ring containing one or two nitrogen atoms and a 6-membered ring; and Z represents an alkylene group, an alkenylene group, an alkylene group, a carbonyl group, an alkylene group containing a carbonyl group or an oxalyl group, or a salt thereof. The compound has calmodulin inhibitory activity and is useful as a treating agent for diseases in the circulatory organs or in the cerebral region which are caused by excessive activation of calmodulin.
