3,7-bis(dimethylamino)phenothiazin-5-ium | An organic cation that is phenothiazin-5-ium substituted by dimethylamino groups at positions 3 and 7. The chloride salt is the histological dye 'methylene blue'. | 3,7-bis(dimethylamino)phenothiazin-5-ium |
7-methylguanosine | A positively charged methylguanosine in which a single methyl substituent is located at position 7. | 7-methylguanosine |
7-methylinosine | A positively charged methylinosine in which a single methyl substituent is located at position 7 on the hypoxanthine ring. | 7-methylinosine |
chelerythrine | A benzophenanthridine alkaloid isolated from the root of Zanthoxylum simulans, Chelidonium majus L., and other Papaveraceae. | chelerythrine |
chelirubine | A benzophenanthridine alkaloid that is sanguinarine bearing a methoxy substituent at position 10. | chelirubine |
chloroeremomycin | An organic cation obtained by deprotonation of the carboxy group and protonation of the three amino functions of chloroeremomycin; major species at pH 7.3. | chloroeremomycin(2+) |
diphenyleneiodonium | An organic cation that is fluorene in which the methylene group is replaced by a positively charged iodine. | dibenziodolium |
diquat | The organic cation formed formally by addition of an ethylene bridge between the nitrogen atoms of 2,2'-bipyridine. Most often available as the dibromide. | diquat |
homoserine lactone | The conjugate acid of homoserine lactone; major species at pH 7.3. | homoserinium lactone |
macrocin | An organic cation that is the conjugate acid of macrocin, obtained by protonation of the tertiary amino group; major species at pH 7.3. | macrocin(1+) |
nitroblue tetrazolium | nitro blue tetrazolium(2+) | |
nostocarboline | A member of the class of beta-carbolines that is 9H-beta-carbolin-2-ium substituted by a chloro group at position 6 and a methyl group at position 2. It is isolated from a fresh water cyanobacterium Nostoc 78-12A and acts as an inhibitor of butyrylcholinesterase. | nostocarboline |
oxazine 1 | oxazine-1 | |
oxomethylium | Conjugate acid of carbon monoxide arising from protonation of the carbon; major species at pH 7.3. | carbon monoxide(1+) |
paraquat | An organic cation that consists of 4,4'-bipyridine bearing two N-methyl substituents loctated at the 1- and 1'-positions. | paraquat |
rhodamine 123 | A cationic fluorescent dye derived from 9-phenylxanthene. | rhodamine 123(1+) |
s-adenosylmethionine | A zwitterionic tautomer of S-adenosyl-L-methionine arising from shift of the proton from the carboxy group to the amino group. | S-adenosyl-L-methionine zwitterion; S-adenosyl-L-methionine |
sepantronium | An organic cation that is 1-(2-methoxyethyl)-2-methyl-1H-naphtho[2,3-d]imidazole-4,9-dione in which the nitrogen at position 3 of the napthoimidazole moiety has been alkylated by a pyrazin-2-ylmethyl group. | sepantronium |
trimethylselenonium | An organic cation consisting of three methyl groups covalently bound to a central selenium atom. | trimethylselenonium |
triphenyltetrazolium | An organic cation that is tetrazole carrying three phenyl substituents at positions 2, 3 and 5. | 2,3,5-triphenyltetrazolium |
zm323881 | A member of the class of quinazolines carrying 2-fluoro-4-methyl-5-hydroxyanilino and benzyloxy substituents at positions 4 and 7 respectively. | ZM 323881 |
