This invention relates to a method of protecting plants, plant parts or soil from fungus attack by utilization of an effective amount of a 1-(alkoxyaroyl)guanidine having the formula: ##STR1## wherein R contains from 7 to 30 carbon atoms and is alkoxyphenyl, alkenyloxyphenyl or alkoxynaphthyl, which radicals are optionally substituted, in either the aliphatic or the aromatic moiety, with a member of the group of halogen, hydroxy and alkyl of from 1 to 2 carbon atoms; and R' is hydrogen, alkyl of from 1 to 4 carbon atoms.
Substituted 2-naphthoylguanidines, process for their preparation, their use as a medicament or diagnostic, and medicament containing them Substituted 2-naphthoylguanidines of the formula I ##STR1## having the meanings indicated in claim 1 for R1 to R8, are suitable as antiarrhythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and infarct treatment and for the treatment of angina pectoris. They also preventively inhibit the pathophysiological processes in the formation of ischemically induced damage, in particular in the production of ischemically induced cardiac arrhythmias.
Substituted 1-naphthoylguanidines, process for their preparation, their use as a medicament or diagnostic, and medicament containing them. Substituted 1-naphthoylguanidines of the formula I ##STR1## in which R2 to R8 have the meanings indicated in the claims, are suitable as antiarrhythmic pharmaceuticals having a cardioprotective component for infarct prophylaxis and infarct treatment and for the treatment of angina pectoris. They also preventively inhibit the pathophysiological processes in the formation of ischemically induced damage, in particular in the production of ischemically induced cardiac arrhythmias.
Guanidine derivatives of the formula: ##STR1## wherein Y is C--R.sup.1 (in which R.sup.1 is hydrogen, lower alkyl, hydroxy, protected hydroxy, etc.,) R.sup.2 is pyrrolyl, tetrazolyl, pyrazolyl, etc., R.sup.3 is hydrogen, lower alkoxy, hydroxy, protected hydroxy, etc., Z is C--R.sup.4 (in which R.sup.4 is hydrogen, carboxy, protected carboxy, nitro, halogen, hydroxy(lower)alkyl, etc.,), and W is R.sup.12 (in which R.sup.12 is hydrogen, lower alkoxy, nitro, hydroxy or protected hydroxy) and pharmaceutically acceptable salts thereof which are useful as a medicament which are useful in inhibiting Na.sup.+ /H.sup.+ exchange in cells and in the prevention of cardiovascular diseases, cerebrovascular diseases, renal diseases, arteriosclerosis and shock.
Substituted benzoylguanidines, process for their preparation, their use as a pharmaceutical or diagnostic, and pharmaceutical containing them. Described are benzoylguanidines of the formula I ##STR1## where R(1) to R(3) are H, Hal, (cyclo)alkyl, N.sub.3, CN or OH, alkyloxy, phenyl, phenoxy or benzoyl, and their pharmacologically acceptable salts, but with the exception of the compounds benzoylguanidine, 4-chlorobenzoylguanidine, 3,4-dichlorobenzoylguanidine and 3- or 4-methylbenzoylguanidine. They are obtained by reacting a compound II ##STR2## with guanidine, L being a leaving group.
3,4,5-Substituted benzoylguanidines, process for their preparation, their use as a medicament or diagnostic and medicament containing them Benzoylguanidines of the formula I ##STR1## where R(1) is R(4)--SO.sub.m or R(5)R(6)N--SO.sub.2 --, where R(4) and R(5) are alk(en)yl, --C.sub.n H.sub.2n --R(7), and where R(7) is cycloalkyl or phenyl, where R(5) is also H, R(6) is H or C.sub.1 --C.sub.4 --alkyl, R(2) is hydrogen, (cyclo)-alk(en)(yn)yl, aryl and hetaryl, R(3) is defined as R(2) and their pharmaceutically tolerable salts are described.
