摘要:
New phthalocyanin derivatives which can be used to differentiate basophils from other blood cells are disclosed. The compounds to which the present invention are quaternary salts of a substituted phthalocyanin structure wherein the substitutions are each independently hydrogen, sulfonate, or a C.sub.1 -C.sub.7 hydrocarbon, optionally containing at least one heteroatom, with the proviso that at least one of them is ##STR1## in which R.sub.1 -R.sub.3 are each independently lower alkyls, cycloalkyls or olefins of which at least one is C.sub.2 -C.sub.4 and two may join to form a ring; R.sub.4 is hydrogen or a C.sub.1 -C.sub.3 alkyl; n is an integer from 1 to 6; M is a polyvalent metal ion. It is preferred that at least two and especially at least three substitutions have the structure so set forth.
摘要:
Provided is a method of treating asthma. The method is the administering to a patient requiring treatment of an effective dose of a benzoxazole-2-carboxylic acid or an ester or therapeutically-acceptable salt of benzoxazole-2-carboxylic acid.
摘要:
A composition for the treatment of acne in the form of a solution, lotion or cream containing from about 1 to 10% by weight of a compound of the formula ##STR1## wherein R is an alkyl having up to 6 carbon atoms or aryl having up to 10 carbon atoms and R.sub.1 and R.sub.2 are independently hydrogen, lower alkyl having up to 6 carbon atoms, phenyl, phenyl-lower alkyl, lower alkylphenyl, halogen, halophenyl, trifluoromethyl, trifluoromethylphenyl, lower alkoxy, methylenedioxy, and lower alkoxyphenyl.
摘要:
The compounds are 1,4-dihydropyridines having antihypertensive activity. A particular compound of this invention is 1,4-dihydro-2,6-dimethyl-4-(2-trifluoromethylphenyl)pyridine-3,5-dicarboxylic acid bis-(2-hydroxyethyl)ester.
摘要:
8-Alkyl and alkenyl-10-hydroxy-5H[1]benzopyranopyridines are prepared by dehydrogenation of the corresponding N-benzyl or N-hydrogen-8-alkyl or alkenyl-1,2,3,4-tetrahydro-5H[1]benzopyranopyridines in a high boiling solvent in the presence of a noble metal dehydrogenation catalyst. Alkyl derivatives of 5-11 carbon atoms are particularly useful. Also the O-acetyl derivatives are very useful. The compounds are central nervous system depressants and animal polyphagic agents.
摘要:
The compounds of this invention are 5-heterocyclic-1,2,3,6-tetrahydro-4(5H)-pyrimidinethiones which have pharmacological activity, in particular gastric acid secretion inhibitory activity, and 5-heterocyclic-1,2,3,6-tetrahydro-4(5H)-pyrimidinones which are intermediates in the preparation therefor.
摘要:
N-Aminomethyl heterocyclic thioacetamide compounds are prepared by reacting a heterocyclic thioacetamide with formaldehyde and an amine. The products inhibit gastric acid secretion.
摘要:
This invention pertains to a novel group of 1,2-dithiin compounds useful as antiinfective agents, and a novel synthetic process to produce the same. The compounds are particularly effective in treating fungal infections, especially those caused by Candida albicans, Cryptococcus neoformans or Aspergillus fumigatus.
