The Introductction of Chlortetracycline hydrochloride
Chlortetracycline hydrochloride is golden yellow or yellow crystals; odorless, bitter taste; gradually darkening when exposed to light. It is slightly soluble in water or ethanol, almost insoluble in acetone, ether or chloroform.
The antibacterial spectrum of chlortetracycline hydrochloride is the same as that of tetracycline, and its efficacy against penicillin-resistant Staphylococcus aureus is slightly stronger than that of tetracycline.
Chlortetracycline HCl, obtained from Streptomycesaureofaciens, is a broad-spectrum antimicrobial agent. chlortetracycline HCl binds strongly to a site in the 30S subunit and inhibits the activity of a wide range of Gram-positive and Gram-negative bacteria, including specialized anaerobes.
Chlortetracycline HCl inhibits bacterial growth mainly by inhibiting protein synthesis at the ribosomal level.ChlortetracyclineHCl inhibits the following Streptococcuspyogelles, Diplococcuspneuliloniap, Bacillussubtilis,Streptococcusfaecalis,Bacillussubtilis,Mycobacteriumranae with MICs of 0.292,0.098,0.195,0.3,0.15,0.3 mg/L, respectively.
Chlortetracycline HCl is a broad-spectrum antibiotic with antibacterial effect on both gram-positive and negative bacteria.
