      • Overview
        • Minocycline is a broad-spectrum, second-generation tetracycline. Like all tetracyclines, Minocycline shows broad spectrum antibacterial and antiprotozoan activity. It was patented in 1961 (American cyanamid), synthesized in 1966 (Lederle Labs). Formulations containing Minocycline have been used for acne vulgaris, Current research is reviewing its neuroprotective and anti-inflammatory effects. Minocycline has been found to have many non-antibiotic biological effects in experimental models wtih inflammatory basis and autoimmune disorders. It is an indirect inhibitor of inducible nitric oxide synthase. Minocycline is soluble in ethanol, methanol, DMF or DMSO but has limited water solubility.

          Background

          Minocycline acts by binding to the 30S and 50S ribosomal sub-units, inhibiting the binding of aminoacyl-tRNA to the ribosomal acceptor (A) site thus blocking protein synthesis. It has many non-antibiotic effects, multiple mechanisms of action have been proposed. A better understanding of the in vivo activity is needed before its therapeutic potential can be accurately assessed.

      • Applications
        • Application Description
          Spectrum: Minocycline has broad-spectrum antibacterial activity and antiprotozoan activity. It has bacteriostatic activity against both Gram-positive and Gram-negative bacteria. It can also be used for methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Acinetobacter baumannii.

          Microbiology Applications: Minocycline is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (Etest, disk diffusion, and broth microdilution methods) against Gram-positive and Gram-negative microbial isolates. Medical microbiologists use AST results to recommend antibiotic treatment options. Representative MIC values include:
          Staphylococcus aureus (methicillin-resistant) 0.25 µg/mL - 8 µg/mL http://antibiotics.toku-e.com/antimicrobial_821_9.html.
          Pharmacokinetic/pharmacodynamic studies on Minocycline are scarce. A hollow-fibre in vitro model to simulate free-drug serum concentration with MRSA strains confimed that this agent is an AUC/MIC-driven agent. The estimation of MIC breakpoints is even more complex since tetracyclines including minocycline have an atypical non-linear protein binding pattern, meaning that the free fraction of the Minocycline
          Cancer Applications: Minocycline inhibits in vitro invasion and experimental pulmonary metastatis in mouse renal adenocarcinoma (MRAC-PM2) cells (Masumori et al, 1994). It has been described to inhibit tumor growht in the xenograft tumor model of C6 glioma cells, inducing autophagic cell death. Its anti-proliferative activiites increase its anti-tumor potential.
