Erythromycin Ethylsuccinate

Erythromycin Ethylsuccinate belongs to the class of medications known as macrolide antibiotics. Erythromycin Ethylsuccinate is an ester of erythromycin suitable for oral administration. Erythromycin Ethylsuccinate is known chemically as erythromycin 2’-(ethylsuccinate). It is used to treat many bacterial infections, including chest infections such as pneumonia, skin infections, and throat infections such as strep throat, diphtheria, ear infections, and certain sexually transmitted infections such as syphilis or chlamydia. Erythromycin ethylsuccinate may also be used to prevent heart problems after dental work for people with heart disease.

Florfenicol, CAS 73231-34-2

What is Florfenicol? Florfenicol is a fluorinated synthetic analog of thiamphenicol. It was successfully developed in late 1980s. It is a broad-spectrum antibacterial classified in chloramphenicol. Florfenicol was marketed first in Japan in 1990. In 1993, Florfenicol was approved by Norway for using in the treatment of dothienesis in trout. In 1995, it was approved by France, England, Austria, Mexico, and Spain for using in the treatment of bovine respiratory diseases. In Japan and Mexico, Florfenicol is approved as feed additive for pigs, preventing and treating swine bacteriosis. It has also been approved in China. Pharmacology of Florfenicol Due to its liposolubility, Florfenicol can diffuse into the cells of bacteria. It works on the 50s subunit of the 70s ribosome and restrain the extension of transpeptidase and thus the formation of peptide chain. The synthesis of protein is therefore prevented. The antibacterial spectrum of Florfenicol is very broad. It is particularly effective against Grams positive and negative bacteria and mycoplasma. The bacteria that are sensitive to Florfenicol include hemophilus, Shigella dysenteriae, salmonella, colibacillus, pneumococcus, Bacillus influenzae, streptococcus, Staphylococcus aureus, chlamydia, Leptospira, and Rickett's organism, etc. in swine and cattle. Oral Florfenicol is fast to absorb. It distributes broadly in the body, with long half-life period, high blood concentration, and lasts long in blood.

Metronidazole Hydrochloride

Metronidazole Hydrochloride is an anti-infective agent used in the treatment of anaerobic bacteria and protozoa.It is also commonly used in the preoperative treatment of patients prior to colorectal surgery or those at high risk for bacterial contamination during the operative intervention.

Oxytetracycline Hydrochloride

Oxytetracycline hydrochloride is a widely used antibiotic with clinically proved activity against gram-positive and gram-negative bacteria, rickettsiae, spirochetes, large viruses, and certain protozoa. It is well tolerated and well absorbed after oral administration. It diffuses readily through the placenta and is present in the fetal circulation. It diffuses into the pleural fluid, and under some circumstances, into the cerebrospinal fluid.

Chloramphenicol Sodium Succinate

Chloramphenicol Sodium Succinate is a mixture of variable proportions of sodium (2R,3R)-2-(2,2-dichloroacetamido)-3-hydroxy-3-(4-nitrophenyl)-propyl succinate and sodium (1R,2R)-2-(2,2-dichloroacetamido)-3-hydroxy-1-(4-nitrophenyl) propyl succinate. It also acts as prodrug. It is effective in treating infections caused by organisms susceptible to its antimicrobial effects when less potentially hazardous therapeutic agents are ineffective or contraindicated.

Chloramphenicol, CAS 56-75-7, chlornitromycin

What is Chloramphenicol? Chloramphenicol is a prototypical broad-spectrum antibiotic. It is a bacteriostatic made of Streptomyces venezuelae by David Gottlieb and became available for clinical application in 1949. It was the first antibiotic to be manufactured synthetically on a large scale. The pharmacokinetics and action mechanism of Chloramphenicol Chloramphenicol is a small molecule which is extremely lipid soluble and relatively unbound to protein. It works by inhibiting protein synthesis through preventing protein chain from extending by inhibiting the peptidyl transferase activity of the bacterial ribosome. It specifically binds to A2451 and A2452 residues in the 23S rRNA of the 50S ribosomal subunit, preventing peptide bond formation. While chloramphenicol and the macrolide class of antibiotics both interact with ribosomes, chloramphenicol is not a macrolide. It directly interferes with substrate binding, whereas macrolides sterically block the progression of the growing peptide. The distribution of Chloramphenicol in the body is not uniform. It is metabolized by the liver to chloramphenicol glucuronate, which is inactive, and the majority of the chloramphenicol dose is excreted by the kidneys as the inactive metabolite, chloramphenicol glucuronate. As a result, the highest concentrations are in the liver and kidney, and the lowest concentrations are in the brain and cerebrospinal fluid. When the meninges are not inflamed, the concentration achieved in brain and cerebrospinal fluid is around 30-50%, while the percentage rises to 89% when the meninges are inflamed. Moreover, chloramphenicol increases the absorption of iron.


4-(3,7-Dimethyl-3-Vinyl-Octa-1,6-Dienyl)-Phenol is a natural phenol and a meroterpene found in Psoralea corylifolia and in Otholobium pubescens. It acts against four major pathophysiologic features that cause acne, suggesting its use to complement and/or enhance the effectiveness of current anti-acne agents. It is widely used in Indian as well as Chinese medicine to treat a variety of diseases and it possesses anti-tumor, anti-bacterial, cytotoxic and anti-helmenthic properties.
