Chemo- and enantio-selective reversed-phase HPLC analysis of rosuvastatin using a cellulose-based chiral stationary phase in gradient elution mode. J Pharm Biomed Anal 2023; 225:115239. [PMID: 36638567 DOI: 10.1016/j.jpba.2023.115239] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/04/2023] [Accepted: 01/06/2023] [Indexed: 01/09/2023]
Abstract
A direct reversed-phase high-performance liquid chromatographic (HPLC) method was developed for determining the content of the enantiomeric impurity of the chiral statin rosuvastatin calcium salt (RSV) in commercial tablets. The baseline enantioseparation was achieved using the Lux Cellulose-2 column and a binary linear gradient of acetonitrile and trifluoroacetic acid 0.05% in an aqueous solution. The flow rate of the mobile phases and column temperature were set at 1.0 mL min- 1 and 40 °C, respectively. In comparison with the isocratic HPLC method reported in the European Pharmacopoeia (EP) monograph for RSV, the gradient elution method offered improved chemo-and enantio-selectivity and reduced analysis times. The limits of quantitation and detection of the enantiomeric impurity were found to be 0.15 and 0.05 µg mL-1.

Optimization of a liquid chromatography method for the analysis of related substances in daclatasvir tablets using design of experiments integrated with the steepest ascent method and Monte Carlo simulation. J Pharm Biomed Anal 2020; 178:112943. [PMID: 31677954 DOI: 10.1016/j.jpba.2019.112943] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 10/17/2019] [Accepted: 10/17/2019] [Indexed: 11/20/2022]
Abstract
Analytical method for the determination of related substances (RS) in Daclatasvir tablets was optimised using quality by design (QbD) approach. Seven degradants (each more than 1.0%) generated during oxidation study, adversely affected the selectivity of the method. Coelution of the degradant peaks with API and known impurities, suggested failure in developing a stability indicating method. To overcome the shortcomings and develop a robust method, QbD principles were incorporated. Resolution was the critical quality attribute (CQA) and buffer pH, column oven temperature, gradient slope and flow rate were the critical method variables (CMVs) studied through design of experiments (DoE). Discovery of an unknown impurity (named as impurity D, about1.0%) was a key finding from this DoE study. The most crucial responses viz. Resolution between impurity D and the main peak and resolution between the main peak and impurity E demanded contradictory pH requirements. To select the right pH, responses were prioritised and eventually to attain the desired resolution between Daclatasvir and impurity E the value for pH was fixed to 3.0. Next, to improve resolution between impurity D and Daclatasvir, method of steepest ascent was applied to locate an apt value for column oven temperature. Accordingly, experiments were performed at different temperatures along the path of rapid increase in response. Finally, at 45 °C (pH :3.0), both the critical pairs were well resolved. The global optimum was determined through a Response surface methodology (RSM) design with pH and column oven temperature as critical factors. pH 3.0, column oven temperature 44 °C, % MP. B 45% and flow rate 1.0 mL min-1 was found to be the optimum condition. Further, the design space was complimented by establishment of a robust zone through Monte Carlo simulation and capability analysis. An analytical control strategy (ACS) was set up to ensure that the method repeatedly meets its acceptance criteria. The optimised method was successfully validated within the factor ranges mentioned in the ACS. Despite various intricacies, the QbD approach facilitated systematic optimisation of a stability indicating robust method.

SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2019; 213:288-300. [PMID: 30708286 DOI: 10.1016/j.saa.2018.12.052] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Revised: 12/20/2018] [Accepted: 12/29/2018] [Indexed: 06/09/2023]
Abstract
Novel univariate and multivariate factor-based calibration-prediction techniques were validated for simultaneous ultraviolet spectrophotometric determination of ribavirin (RIV), daclatasvir (DAV), sofosbuvir (SOV), and sorafenib (SON) which are co-administered for treatment of hepatocellular carcinoma (HCC) that results from Hepatitis C-virus (HCV) infection in their commercial products and in biological fluids. Determination of these compounds is essential owing to their pharmacotherapeutic benefits. Due to spectral overlapping of RIV, DAV, SOV, and SON, univariate extended derivative ratio (EDR) method and multivariate partial least-squares (PLS) and principal component regression (PCR) methods were used for constructing the calibration curves. The extended derivative ratio (EDR) absorption maxima at 215 nm and minima at 310.5 nm was used for determination of RIV and DAV, respectively and absorption maxima at 240.3 nm and minima at 284.5 nm for determination of SOV and SON, respectively. The linearity was established over the range of 6-42 μg mL-1, 4-16 μg mL-1, 10-70 μg mL-1, and 3-9 μg mL-1 for RIV, DAV, SOV and SON with correlation coefficient (r2) of 0.9997, 0.9997, 0.9999 and 0.9997, respectively. This method was effectively applied to pure, pharmaceutical preparations and to spiked human urine and plasma. PLS and PCR models were established for the determination of the studied drugs in the range of 6-42, 4-16, 10-70 and 3-9 μg mL-1 for RIV, DAV, SOV, and SON, respectively. Furthermore, updating the PLS model (PLS model update) were allowed for the determination of these drugs in spiked human urine, plasma and drug-dissolution test of their tablets. The obtained results were compared to official and reported method showing that there were no significant differences. The results of applying PLS and PCR models for evaluation of RIV, DAV, SOV, and SON in human urine samples as real samples were also encouraging. It is expected that the suitable features of the proposed method make it helpful for biological and clinical applications.

Abstract
A simple and highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) bioanalytical method was developed and fully validated for the first time for the simultaneous determination of newly discovered antiviral drugs, namely sofosbuvir (SOF) and daclatasvir (DAC) in human plasma. Tadalafil (TAD) was used as internal standard (IS). SOF, DAC and TAD (IS) were extracted from plasma using liquid-liquid extraction technique with methyl tert-butyl ether. The chromatographic separation was carried out using ZorbaxSB-C18 column (4.6 × 50 mm,5 μm) and 5 mm ammonium formate buffer (pH 3.5)-acetonitrile (50:50, v/v) as mobile phase in an isocratic elution mode pumped at a flow rate 0.7 mL min-1 . The quantitation was performed on API4500 triple quadrupole tandem mass spectrometer with positive electrospray ionization interface in multiple reaction monitoring mode. Validation was applied according to US Food and Drug Administration guidelines for bio-analytical methodswith respect to linearity, precision, accuracy, selectivity, carry-over, stability and dilution integrity. Linearity was obtained over concentration ranges of 0.3-3000 and 3-3000 ng mL-1 for SOF and DAC, respectively, by applying a weighted least-squares linear regression method (1/x2 ). The proposed method could be applied successfully in bioequivalence and/or clinical studies for therapeutic drug monitoring of patients undergoing dual combination therapy as the latter combination proved more efficacious and powerful tool for the complete treatment of hepatitis C genotype 3 within 16 weeks. The suggested method has been applied successfully to pharmacokinetic studies with excellent assay ruggedness and reproducibility.

Abstract
A series of ecofriendly ternary deep eutectic solvents (DESs) with different molar ratios were prepared as candidate functional monomers. Three of the optimal ternary DESs as functional monomers were applied to the preparation of molecularly imprinted polymers (MIPs). After synthesis, the proposed polymers were characterized by elemental analysis (EA), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller surface area measurements (BET) and Fourier transform infrared spectroscopy (FT-IR). These MIPs based on ternary DESs with different molar ratios exhibited different absorption capacities of levofloxacin. A sample of levofloxacin (500ng) was dissolved in a millet extractive (10mL). All MIPs were used as SPE adsorbents to purify the extracts. According to characterization result, the ternary DES-3 (1:3:1.5) was joined in the synthetic process of MIP-1. The green ternary DES-3-based MIPs had the best selectivity recovery for levofloxacin (91.4%) from the millet extractive. The best selectivity of MIP-1 was attributed to the novel monomer (ternary DES) in the preparation of the materials. Overall, ternary DES-based MIPs have potential applications as media in many research areas.

Abstract
A comprehensive stability indicating HPLC with diode array detection method was developed for the determination of the recently approved antiviral drug daclatasvir dihydrochloride (DCV) which is used for the treatment of chronic Hepatitis C Virus (HCV) genotype 3 infection. Effective chromatographic separation was achieved using Waters C8 column (4.6×250mm, 5μm particle size) with isocratic elution of the mobile phase composed of mixed phosphate buffer pH 2.5 and acetonitrile in the ratio of 75:25 (by volume). The mobile phase was pumped at a flow rate of 1.2mL/min, and quantification of DCV was based on measuring its peak areas at 306nm. DCV eluted at retention time 5.4min. Analytical performance of the proposed HPLC procedure was thoroughly validated with respect to system suitability, linearity, range, precision, accuracy, specificity, robustness, detection and quantification limits. The linearity range was 0.6-60μg/mL with correlation coefficient>0.99999. The drug was subjected to forced degradation conditions of neutral, acidic and alkaline hydrolysis, oxidation and thermal degradation. The proposed method proved to be stability-indicating by resolution of the drug from its forced-degradation products. The validated HPLC method was successfully applied to analysis of the cited drug in its tablets.
