Current Research

  1. Mass spectrometric- and biocomputational-based proteomic research
    1. Development of mass spectrometric epitope mapping methods.

This research work focused on developing electrospray mass spectrometry-based epitope mapping methods in the gas phase. Intact Transition Epitope Mapping – One-step Non-covalent force Exploitation (ITEM-ONE), a mass spectrometric epitope mapping method in which epitopes are identified by the accurate masses of the complex released peptides, was developed. Also, the Intact Transition Epitope Mapping – Targeted High-Energy Rupture of Extracted Epitopes (ITEM-THREE) method identifies epitope peptides by partial amino acid sequencing of the CoRPs rapidly and accurately. In both methods, neither antibodies nor immune complexes are immobilized. Instead, both methods used ion mobility mass spectrometry for ion separation coupled with gas phase dissociation of immune complexes in the mass spectrometer's collision cell. The speed by which ITEM-ONE or ITEM-THREE can be conducted and the low required sample amounts outperform many of the other epitope mapping methods. Intact Transition Epitope Mapping - Thermodynamic Weak-force Order (ITEM-TWO) enables rapid epitope mapping and determination of apparent dissociation energies of immune complexes with minimal in-solution handling and characterizes two most important antibody properties, specificity, and affinity has been developed. ITEM-TWO was used to investigate the influence of a solvent’s composition on the stability of desorbed and multiply charged RNAse S ions by analyzing the non-covalent complex’s gas-phase dissociation processes. From the experimental data, it is concluded that the stability of RNAse S in the gas phase is independent of its in-solution equilibrium but is sensitive to the complexes’ gas-phase charge states. Bio-computational in-silico studies explained quantitative experimental data with single amino acid residue resolution.

 

    1. Africa-Ready Malaria Screening (ARMS).

This research focused on the mass spectrometric characterization of the MSP119 antigen to antiMSP119 (G17.12) monoclonal antibody interaction. The malarial antigen-containing fusion protein, MBP-pfMSP119, was cloned in Escherichia coli, which was structurally and functionally characterized before and after high pressure–assisted enzymatic digestion. ITEM-THREE was used to determine the area on the MBP-pfMSP119 antigen surface recognized by the antipfMSP119 antibody G17.12, which was part of an assembled epitope on the MBP-pfMSP119 antigen. This research established a workflow to obtain high quality control data for diagnostic assays, including ITEM-THREE as a powerful analytical tool. Further studies are being conducted on the computational design of MSP119 malaria antigen mimotope peptide and mass spectrometric characterization of molecular details of the predicted mimotope peptide as well as mass spectrometric investigations of antibody complexes to gain experimental details of specificity and affinity. Commercially available antibody for the detection of MSP119-specific malaria antigen in patients’ sera by ELISA will then be applied. Finally, developing the MSP119 malaria antigen mimotope peptide as a screening assay to determine the presence of anti-malaria antibody titers in persons who have gained immuno-protection either via vaccination or naturally will be conducted.

 

  1. Quality assessment of orthodox, and herbal medicinal products.
  1. Screening methods for the detection of substandard/falsified medicines.

The goal of this study was to use combined screening methods for the rapid detection of substandard/falsified medicines since it has become a global public health challenge. This study used three screening methods (GPHF Minilab, Colorimetry, and Counterfeit Drug Indicator) and one confirmatory method (high-performance liquid chromatography) for the quality assessment of different batches of artemether/lumefantrine dosage forms. The study's outcome showed that the combined screening methods and the confirmatory method provided equivalent quality assessment profiles and therefore demonstrated the usefulness of combined screening methods for the detection of falsified and/or substandard medicines in the absence of a confirmatory method. This approach is cheap, rapid, and can be applied to field monitoring substandard/falsified medicines.

 

  1. Quality assessment of herbal medicinal products.

Studies undertaken in this area assessed the quality of herbal medicinal products. These studies focused on a) the determination of residual solvents in herbal medicinal products using gas chromatography, b) monitoring and risk assessment of pesticide residues in herbal medicinal products using gas chromatography-mass spectrometry, c) classification of herbal medicinal products using XRF spectroscopy in combination with chemometric analysis, and d) classification and detection of expired antimalarial herbal medicinal product using ultraviolet-visible spectroscopy and chemometrics. These studies documented the presence of residual solvents and pesticide residues in some herbal medicinal products in Ghana. Also, these studies showed that analytical methods combined with a chemometric strategy could be used for a) the classification and detection of antimalarial herbal medicinal products and b) the classification of herbal medicinal products into various therapeutic agents based on their elemental composition. These studies suggested the need for continual monitoring of contaminants in herbal medicinal products as a public health concern and the potential need for more stringent regulation of herbal medicinal products marketed in Ghana.

 

  1. Pharmacokinetics studies of drug-drug, and drug-herb interaction.

This research focused on applying analytical methods for pharmacokinetics studies of drugs and drug-drug interaction. This work focused on the pharmacokinetics of drugs using animal models. The studies documented the effect of a) betamethasone on the pharmacokinetics of amikacin, b) aminophylline on the pharmacokinetics of amikacin, and c) the effect of Cellgevity® on the pharmacokinetics of carbamazepine. Results from the studies showed a) the possible interaction between aminophylline and amikacin, b) betamethasone altered the pharmacokinetics of amikacin, and c) Cellgevity® altered the pharmacokinetics of carbamazepine.
