摘要:
There are provided substituted acetamide derivatives represented by general formula (I): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11, R.sup.12, R.sup.13, n and Z are defined in the specification. The substituted acetamide derivatives strongly inhibit acylcoenzyme A cholesterol acyltransferase (ACTA) and are expected to be effective for the treatment and prevention of hypercholesterolemia, hyperlipemia and arteriosclerosis.
摘要:
Substituted heterocyclic derivatives represented by the formula (I) ##STR1## wherein R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, Q.sup.1, Q.sup.2, Q.sup.3, Q.sup.4, X and Y are as defined, including, specifically, the compound (E)-3-[3-[3-(2-methoxymethyl-8,8-dimethyl-4-nonen-6-ynyl)phenoxymethyl]phenyl]thiophene, exhibit squalene epoxidase inhibiting activity and are useful in the treatment or prophylaxis of hypercholesterolemia, hyperlipidemia and arteriosclerosis.
摘要:
As new compounds are now provided N-methyl-3-(3,4-dihydroxyphenyl)serine alkyl esters which are effective as an .alpha.-adrenergic and .beta.-adrenergic agent to stimulate the .alpha.-adrenergic and .beta.-adrenergic functions of the central nervous system of mammalian animals and are expectable to be useful for therapeutic treatment of disorders as invoked by reduced biological activities or functions of the .alpha.- and/or .beta.-adrenergic neurons. N-methyl-L-threo-3-(3,4-dihydroxyphenyl)serine (C.sub.1 -C.sub.6) alkyl esters are preferred amongst the new compounds of this invention.
摘要:
An L-dopa derivative represented by formula (I) ##STR1## wherein one of R.sup.1 and R.sup.2 denotes a hydrogen atom and the other denotes a group of formula R--CO-- in which R denotes an alkyl, alkenyl, optionally substituted cycloalkyl, optionally substituted phenyl, optionally substituted aralkyl, lower alkoxy or optionally substituted aralkyloxy group,and its acid addition salt. The compounds are useful in the medical field, especially in the treatment of a series of diseases called Parkinson's disease or Parkinsonism.
