Oxytetracycline is a broad-spectrum tetracycline antibiotic that inhibits protein synthesis in both Gram-positive and Gram-negative bacteria. The features of its biosynthesis often serve as a representative example for understanding the synthesis of other type II polyketides.1 Oxytetracycline is also used to examine the acquisition of oxytetracycline-resistance genes, which are associated with the development of antibiotic resistance.2

Exploring solid forms of Oxytetracycline hydrochloride
Int J Pharm 2020 Jul 30;585:119496.PMID:32504775DOI:10.1016/j.ijpharm.2020.119496.
Oxytetracycline hydrochloride, an antibiotic of the tetracycline family, is a polymorphic drug that evidences erratic absorption in oral administration. Additionally, poor solid state characterization of the polymorphs and diversity in the existing nomenclature impede the correct identification of the raw materials. In this work, Oxytetracycline hydrochloride solid forms were prepared from isopropyl alcohol, ethanol and methanol through different crystallization techniques, and then their physicochemical and microbiological properties were evaluated. A combination of advanced techniques such as solid state nuclear magnetic resonance, powder X-ray diffraction, infrared spectroscopy, thermal analysis, scanning electron microscopy and energy-dispersive X-ray spectroscopy were used in the characterization of solid samples giving clear evidence of the existence of three stable and one metastable solid forms of the Oxytetracycline hydrochloride. Solubility was determined in aqueous solution, simulated gastric fluid, and simulated intestinal fluid. In addition, microbiological studies were performed. The polymorphs showed similar antimicrobial activity against Escherichia coli and Staphylococcus aureus. Therefore, these solid forms of Oxytetracycline hydrochloride constitute promising candidates to encourage studies for repositioning old and known antibiotic drugs in the developing strategies for new therapeutic alternatives.
Simultaneous analysis of Oxytetracycline hydrochloride, lidocaine, and bromhexine hydrochloride in the presence of many interfering excipients
Arch Pharm (Weinheim) 2021 Oct;354(10):e2100131.PMID:34131945DOI:10.1002/ardp.202100131.
A gradient elution high-performance liquid chromatographic method with a diode array detector is introduced for the first time for the simultaneous estimation of three drugs, namely, Oxytetracycline hydrochloride (OXT), lidocaine (LDC), and bromhexine hydrochloride (BRH), in a veterinary formulation (OxyClear® solution) that contains many interfering additives. The method used a C-8 column. The chromatographic eluting solution included acidified water (0.1% trifluoroacetic acid in water) and acetonitrile at a 1-ml/min flow rate and 254 nm as a nominated detection wavelength. The chromatographic process was assessed in terms of linearity, precision, accuracy, LOD, and LOQ. OXT, LDC, and BRH were linear in the range of 1-60, 5-100, and 1-60 μg/ml, respectively. The three drugs were determined successfully without the interference of three excipients having UV absorbances. Furthermore, the purities of the peaks of the three drugs were confirmed by comparing the UV spectra of investigated peaks to the UV reference spectra in Clarke's Analysis of Drugs and Poisons. The greenness value of the method was 0.69 with a faint green-colored pictogram using the AGREE tool. These merits recommend the application of the planned method in QC laboratories for purity testing and concentration assays for the pure drugs and commercial formulations.
High-capacity removal of Oxytetracycline hydrochloride from wastewater via Mikania micrantha Kunth-derived biochar modified by Zn/Fe-layered double hydroxide
Bioresour Technol 2022 Oct;361:127646.PMID:35868467DOI:10.1016/j.biortech.2022.127646.
Antibiotic contamination in water has been an increasing global concern, and how to effectively remove antibiotics (e.g., oxytetracycline [OTC] hydrochloride) from wastewater becomes imperative. In this study, the biochar derived from an invasive plant (Mikania micrantha Kunth) was synthesized with Zn/Fe- layered double hydroxide (LDH) by co-precipitation method (ZnFe-LDH/MBC) to remove OTC from water. ZnFe-LDH/MBC posed the highest OTC removal performance of 426.61 mg/g. ZnFe-LDH/MBC exhibited stability and efficiency in OTC adsorption at different pH levels and under interfering conditions with co-existing ions, as well as outstanding regeneration capabilities during adsorption-desorption cycles. Furthermore, the removal of OTC by ZnFe-LDH/MBC was mediated by several processes including pore filling, hydrogen bonding force, electrostatic interaction, π-π interaction, as well as complexation. Consequently, ZnFe-LDH/MBC has excellent potential for the purification of OTC pollutants that is low-cost, efficient, and environmentally friendly.
Performance and mechanism of sycamore flock based biochar in removing Oxytetracycline hydrochloride
Bioresour Technol 2022 Apr;350:126884.PMID:35219786DOI:10.1016/j.biortech.2022.126884.
In this study, sycamore flocs (SF), which caused environmental and health problems, were utilized to prepare biochar. SFB2-900 obtained under the conditions of activation agent K2CO3, pyrolysis temperature 900℃ and m(K2CO3):m(BC) 2 had the strongest adsorption capacity (730 mg/g) for Oxytetracycline hydrochloride (OTC-HCl). The pseudo-second-order kinetic model and Langmuir model described the adsorption kinetics and isotherms best. SFB2-900 exhibited high OTC-HCl adsorption capacity in both higher ionic strength and wide pH range. The theoretical simulation indicated that the closest interaction distance between OTC-HCl and SFB2-900 was 2.44 Å via π-π stacking configuration. Pore filling, π-π electron donor acceptor (EDA) interaction, H-bonding and electrostatic interactions were also involved in the process of OTC-HCl removal. SFB2-900 showed great removal efficiency for OTC-HCl in different water matrices and good regeneration ability. This study solved the problems caused by SF, realized waste biomass recycling, and achieved preparing high-efficient adsorbent for antibiotic.
Community-level and function response of photoautotrophic periphyton exposed to Oxytetracycline hydrochloride
Environ Pollut 2022 Feb 1;294:118593.PMID:34864100DOI:10.1016/j.envpol.2021.118593.
Periphyton is considered important for removal of organic pollutants from water bodies, but knowledge of the impacts of antibiotics on the community structure and ecological function of waterbodies remains limited. In this study, the effects of Oxytetracycline hydrochloride (OTC) on the communities of photoautotrophic epilithon and epipelon and its effect on nitrogen and phosphorus concentrations in the water column were studied in a 12-day mesocosm experiment. The dynamics of nitrogen and phosphorus concentrations in the epipelon and epilithon experiment showed similar patterns. The concentrations of total nitrogen, dissolved total nitrogen, ammonium nitrogen, total phosphorus and dissolved total phosphorus in the water column increased rapidly during the initial days of exposure, after which a downward trend occurred. In the epilithon experiment, we found that the photosynthesis (Fv/Fm) and biomass of epilithon were significantly (P < 0.05) stimulated in the low concentration group. Contrarily, growth and photosynthesis (Fv/Fm) were significantly (P < 0.05) reduced in the medium and high concentration group. We further found that the photosynthetic efficiency of photoautotrophic epilithon was negatively correlated with the concentrations of nitrogen and phosphorus in the water column (P < 0.05). Principal coordinate analysis (PCoA) showed that the communities of epilithic algae in the control group and in the low concentration group were significantly (P < 0.05) different from that of the high concentration group during the initial 4 days. After 8 days' exposure, all groups tended to be similar, indicating that epilithon showed rapid adaptability and/or resilience. Similar results were found for the relative abundance of some epilithic algae. Our findings indicate that the biofilm system has strong tolerance and adaptability to OTC as it recovered fast after an initial suppression, thus showing the important role of periphyton in maintaining the dynamic balance of nutrients with other processes in aquatic ecosystems.
