一般描述

Chemical structure: macrolide

应用

Clarithromycin is a semisynthetic macrolide antibiotic that is derived from erythromycin. Clarithromycin may be bacteriostatic or bactericidal depending on the organism and drug concentration . Clarithromycin may be used to attenuate cardiac transplantation rejection via matrix metalloproteinase suppression. Clarithromycin has been used to study inflammatory markers in chronic obstructive pulmonary disease (COPD). It is used to study bacterial protein synthesis and peptide translation.

生化/生理作用

克拉霉素是一种大环内酯类抗生素，能干扰细菌蛋白质的合成。克拉霉素是红霉素的酸稳定形式，对革兰氏阴性细菌特别有效。它的半衰期很短，但是其代谢产物 14-羟基克拉霉素对某些细菌的活性几乎是克拉霉素的两倍。
Clarithromycin inhibits bacterial protein synthesis by binding to the bacterial 50S ribosomal subunit. Binding inhibits peptidyl transferase activity and interferes with amino acid translocation. Clarithromycin is first metabolized to 14-OH clarithromycin, which is active and works synergistically with its parent compound. Clarithromycin penetrates the bacteria cell wall and reversibly binds to domain V of the 23S ribosomal RNA of the 50S subunit of the bacterial ribosome, blocking translocation of aminoacyl transfer-RNA and polypeptide synthesis. Clarithromycin also inhibits the hepatic microsomal CYP3A4 isoenzyme and P-glycoprotein, an energy-dependent drug efflux pump.

制备说明

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. I want to use Carithromycin, Product C9742, in cell culture.  What solvent can I use?

    One reference mentions making stock solutions in ethanol at 2 mg/mL (Kikuchi, T., et al., J. Antimicrobial Chemotherapy, 49, 745-755 (2002)). Another paper infers that clarithromycin is soluble in ethanol to a minimum of 30 mg/mL. (Hoffman, H.L. et al., Antimicrob Agents Chemother. 47(2), 739-746 (2003)).

  4. Can I dissolve Carithromycin, Product C9742, in DMSO?

    While we have not tested this ourselves, one publication mentions preparation of clarithromycin in DMSO at 100 mM.  Nagaya, T., et al., J. Clin. Invest., 106(3), 393-402 (2000).

  5. How should I store stock solutions of Carithromycin, Product C9742?

    While we have not tested solution stability ourselves, one reference indicates storage of stock solutions of clarithromycin at -20°C, with preparation of fresh stock solutions once a month. Reference: Chen, B. -M., et al., J. Pharm. Biomed. Anal., 42(4), 480-487 (2006).
