Beta Blockers

Applications Centrally acting α-adrenoceptor agonist. Antihypertensive. References Urosevic, D., et al.: Br. J. Pharmacol., 142, 609 (2004), Remko, M., et al.: Bioorg. Med. Chem., 14, 1715 (2006), Nikolic, K., et al.: Bioorg. Med. Chem., 16, 7134 (2008).

rac-N-Desbutyroyl acebutolol is a prodrug that is metabolized to the active form, acebutolol. The metabolism of rac-N-desbutyroyl acebutolol is mediated through cytochrome P450 (CYP) enzymes, specifically CYP2D6. Rac-N-desbutyroyl acebutolol has been shown to inhibit the growth of bacteria in vitro and in vivo. It has also been shown to have therapeutic effects on diabetic patients with high levels of fatty acids in their blood. Rac-N-desbutyroyl acebutolol has also been found to be effective for the treatment of patients with polycarboxylic acid exposure and dna replication diseases.

Erythromycin E is a diluent that is used to make erythromycin solutions. It has been shown to have bioactive molecules by incubating it with chromatographic methods. These bioactive molecules are conjugates of erythromycin and methyl ethyl groups. Erythromycin E has also been shown to have genetic mechanisms, which may relate to its ability to inhibit the synthesis of inflammatory cytokines such as IL-1β and IL-8 in the airways. The acetate extraction method is used for the production of erythromycin E. This process involves extracting erythromycin from Streptomyces bacteria grown in an acetate buffer solution.
