Chloramphenicol Succinate is prepared by acylation of chloramphenicol with succinic anhydride to provide a water soluble pro-drug. Chloramphenicol is released in the presence of succinate dehydrogenase in the human gut.
Chloramphenicol Succinate is soluble in ethanol, methanol, DMF and DMSO.
We also offer:
- Chloramphenicol, USP (C028)
- Chloramphenicol Solution (50 mg/ml) (C090)
- Chloramphenicol Palmitate (C168)
- Chloramphenicol Succinate Sodium (C170)
- Chloramphenicol Acetate (C172)
| Mechanism of Action | After entering a bacterial cell, Chloramphenicol reversibly binds to the peptidyltransferase center at the 50S ribosomal subunit of 70S ribosome, preventing peptide bond formation. Resistance to Chloramphenicol may be due to decreased cell permeability or a mutation in the 50S ribosomal subunit |
| Microbiology Applications | Chloramphenicol is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options. Representative MIC values include:
Chloramphenicol is used as a selective agent in: Dermasel Agar - Dermasel Selective Supplement. Selection of dermatophyte fungi from hair, nails, and skin scrapings. Chromogenic Candida Agar - Candida Selective Supplement |
| Plant Biology Applications | Chloramphenicol is gene selection agent for resistant plants containing the cat gene. Chimeric genes made up of the nopaline synthase promoter and bacterial coding sequences that specify resistance to chloramphenicol were inserted into a Ti plasmid vector and used to transform tobacco protoplasts. The use of a non-oncogenic Ti plasmid was used and phenotypically normal fertile plants regenerated from the resistant calli, thus providing a natural environment for studying gene expression and development of plant cells. (De Bloc et al, 1984). |
| Cancer Applications | Researchers at the University of Manchester, UK found a conserved phenotypic dependence on the biogenesis of mitochondria for the expansion of cancer stem cells. Since Chroramphenicol can inhibit mitochrondrial biogenesis, it was found to inhibit tumor-sphere formation in MCF7 cells. This approach is mutation-independent, and treats cancer like a single disease of ‘stemness’, independent of tumor type. This approach was successful in vitro with 12 different cancer cell lines, across 8 different tumor types (breast, DCIS, ovarian, prostate, lung, pancreatic, melanoma, and glioblastoma (brain)(Lamb et al, 2015). |
