摘要:
A pharmaceutical composition comprising a pyrimidine represented by the following formula ##STR1## wherein R.sup.1 represents a hydrogen atom, an acyl group having 2 to 4 carbon atoms, an alkoxycarbonyl group having 2 to 5 carbon atoms, an alkoxycarbonylmethyl group having 3 to 5 carbon atoms, a 3,4-dimethoxybenzoyl group or a 3,4-methylenedioxybenzyl group,R.sup.2 represents a hydrogen atom, an amino group, a monoalkylamino group having 1 to 4 carbon atoms, an alkoxy group having 1 to 5 carbon atoms or an alkoxycarbonyl group having 2 to 4 carbon atoms,R.sup.3 represents a hydrogen atom, an alkoxycarbonyl group having 2 to 4 carbon atoms, a dialkylaminocarbonyl group having 1 to 9 carbon atoms in each alkyl moiety, an alkoxy group having 1 to 5 carbon atoms, or a hydroxyethyl group, R.sup.2 and R.sup.3, together with the carbon atoms to which they are bonded, may form a 5- to 7-membered carbocyclic ring or a heterocyclic ring having N, O or S as the hetero atom, and R.sup.4 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or an alkylthio group having 1 to 4 carbon atoms,or a pharmaceutically acceptable salt thereof. The above active compound has activities of promoting growth of nerve cells, forming neurites, and restoring motor functions, and is useful as an agent for treating diseases of peripheral and central nerves.
摘要:
The present invention provides a method for the screening of a wound-healing agent, which comprises determining a substance to be active as a wound-healing agent on the basis of potentiation or modification of biological activities of a growth and/or differentiation factor, a growth hormone or a cytokine. This invention also provides a wound-healing method, which comprises as an active ingredient a compound of the following formula (1) or formula (2) found to be active by the screening method. ##STR1##
摘要:
Disclosed herein are phosphoric acid esters of myoinositol, which are represented by the following general formula (I): ##STR1## and their salts, as well as a preparation process thereof. The myoinositol derivatives can each be obtained by causing a phosphorylating agent to act on a myoinositol derivative substituted with catalytic reduction removable substituent groups at the positions other than those desired to be substituted by phosphoric acid residual groups and then catalytically reducing the thus-phosphorylated myoinositol.
摘要:
Disclosed herein is an antihypertensive preparation containing, as an active component, a novel quinazoline derivative represented by the following general formula or a salt thereof: ##STR1## wherein R.sup.100 means a hydrogen atom or methoxy group, R.sup.200 and R.sup.300 denote individually a hydrogen atom or lower alkoxy group, R.sup.400 is a hydrogen atom or amino group, l stands for 2 or 3, and Het is a specific hetero ring group.
摘要:
Disclosed are 2-thiazol derivatives having the general formula ##STR1## where R.sub.1 and R.sub.2 independently represent lower alkyl radicals having 1 to 4 carbon atoms and X represents a lower alkyl radical, a lower alkoxy radical, a lower alkoxycarbonyl radical, a halogenoalkoxy radical, a radical of the formula ##STR2## or a radical of the formula ##STR3## Also disclosed are a process for preparing the derivatives and pharmaceutical compositions having immunomodulatory activity which comprise the derivatives as the active ingredient.
