1.Interactions of a non-fluorescent fluoroquinolone with biological membrane models: A multi-technique approach.
Sousa CF1, Ferreira M1, Abreu B1, Medforth CJ1, Gameiro P2. Int J Pharm. 2015 Nov 30;495(2):761-70. doi: 10.1016/j.ijpharm.2015.09.037. Epub 2015 Sep 21.
Fluoroquinolones are antibiotics which act by penetrating into bacterial cells and inhibiting enzymes related to DNA replication, and metal complexes of these drugs have recently been investigated as one approach to counteracting bacterial resistance. In this work, we apply a multi-technique approach to studying the partition coefficient (Kp) for the non-fluorescent third-generation fluoroquinolone sparfloxacin or its copper-complex with lipid membrane models of Gram-negative bacteria. The techniques investigated are UV-vis absorption and (19)F NMR spectroscopies together with quenching of a fluorescent probe present in the lipids (using steady-state and time-resolved methods). (19)F NMR spectroscopy has previously been used to determine the Kp values of fluorinated drugs but in the case of sparfloxacin did not yield useful data. However, similar Kp values for sparfloxacin or its copper-complex were obtained for the absorption and fluorescence quenching methods confirming the usefulness of a multi-technique approach.
2.Comprehensive evaluation of formulation factors for ocular penetration of fluoroquinolones in rabbits using cassette dosing technique.
Sharma C1, Biswas NR2, Ojha S3, Velpandian T2. Drug Des Devel Ther. 2016 Feb 22;10:811-23. doi: 10.2147/DDDT.S95870. eCollection 2016.
OBJECTIVE: Corneal permeability of drugs is an important factor used to assess the efficacy of topical preparations. Transcorneal penetration of drugs from aqueous formulation is governed by various physiological, physiochemical, and formulation factors. In the present study, we investigated the effect of formulation factors like concentration, pH, and volume of instillation across the cornea using cassette dosing technique for ophthalmic fluoroquinolones (FQs).
3.Cutaneous Phototoxicity: Clinical Observations versus Histopathological Findings.
Learn DB1, Elliott MW2. Toxicol Pathol. 2016 Apr 12. pii: 0192623316643617. [Epub ahead of print]
Determination of test material-induced cutaneous phototoxicity for risk assessment has traditionally been based on visually observed skin reactions such as erythema, edema, and flaking. Because of its role in determining a toxic effect, the use of histopathological evaluation in this determination arises from time to time. However, there is little published information regarding the time course and types of histopathologic changes in the skin after test material-induced phototoxic insult nor any regulatory requirement or precedent for its use. This work evaluated both the visual and histopathological time course of the phototoxic response of the skin of the Long-Evans rat after oral administration of the phototoxins sparfloxacin and 8-methoxypsoralen (MOP) followed by a single exposure to solar-simulated ultraviolet radiation. Both sparfloxacin and 8-MOP elicited visual cutaneous reactions and microscopic changes consistent with a phototoxic response.
4.FREEQUNCY OF ESCHERICHIA COLI IN PATIENTS WITH COMMUNITY ACQUIRED URINARY TRACT INFECTION AND THEIR RESISTANCE PATTERN AGAINST SOME COMMONLY USED ANTI BACTERIALS.
Ahmad W, Jamshed F, Ahmad W. J Ayub Med Coll Abbottabad. 2015 Apr-Jun;27(2):333-7.
BACKGROUND: Urinary tract infection (UTI) is a very common health problem and Escherichia coli (E coli) are the most common organisms associated with community acquired UTI. Unfortunately these bacteria have developed extensive resistance against most of the commonly used antibacterials. The objective of this study was to determine the frequency and resistance pattern of E. Coli in patients of community acquired UTI in an area in northern part of Pakistan.
