Inhibition of photosynthesis in Anacystis by alkylbenzimidazoles was written by Buechel, Karl H.;Roechling, Hans;Baedelt, H.;Gerhardt, Bernt;Trebst, Achim. And the article was included in Zeitschrift fuer Naturforschung, Teil B: Anorganische Chemie, Organische Chemie, Biochemie, Biophysik, Biologie in 1967.Electric Literature of C15H22N2 This article mentions the following:
Seventeen 2-alkylbenzimidazoles were tested for their ability to inhibit photosynthesis in A. nidulans. Inhibition increased with increasing chain length reaching a maximum with 2-undecylbenzimidazole, with 11 carbons in the side chain, which inhibited photosynthesis by 50% at 4.4 γ/ml. compared with 4650 γ/ml. for 2-propylbenzimidazole or 55 γ/ml. for 2-(dodecylamino)benzimidazole. The photosynthetic inhibition was due to an uncoupling of photophosphorylation. Noncyclic photophosphorylation coupled to ferricyanide reduction in the cell-free alga preparation was more sensitive to 2-undecylbenzimidazole than was cyclic photophosphorylation. In the experiment, the researchers used many compounds, for example, 2-Octylbenzimidazole (cas: 13060-24-7Electric Literature of C15H22N2).
2-Octylbenzimidazole (cas: 13060-24-7) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
