Chemistry is traditionally divided into organic and inorganic chemistry. category: indole-building-block. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 3189-13-7
Novel [4′-(3″-indolyl)-piperidino]-alkyl-arylketones of the formula SPC1 Wherein R is selected from the group consisting of hydrogen and alkoxy of 1 to 5 carbon atoms, R1 and R2 are individually selected from the group consisting of hydrogen and alkyl of 1 to 5 carbon atoms, n is 2 or 3 and X is selected from the group consisting of hydrogen, fluorine, chlorine and bromine and their non-toxic, pharmaceutically acceptable acid addition salts having central nervous system depressant activity.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: indole-building-block, you can also check out more blogs about3189-13-7
