During the last decade, the focus of bioanalytics shifted from the mere analysis of biomacromolecules to the application of proteins and nucleic acids for analytical purposes, e.g. accessing the biological role of cellular constituents, target identification and validation, quantification of receptor-ligand interactions and others. The increasing impact of combining biomacromolecules with standard analytic devices can be exemplified by the central role of DNA and protein micro-arrays in the fields of genomics, proteomics, transcriptomics or pharmacogenomics. Medicinal chemistry is considered as the scientific discipline concerned with the discovery, design, identification, and preparation of biologically active compounds and the interpretation of their mode of action at the molecular level and their metabolites. From this definition it is evident that bioanalytical tools put into service of medicinal chemistry needs can contribute substantially to progress in drug discovery, design and identification, especially in cases when these tools are well-adapted for miniaturisation and automation to enable high throughput screening. Many successful examples of combining biomacromolecules with standard instrumental analytics indicate that the former role of biochemical testing in medicinal chemistry is more and more replaced by what we call molecular bioanalytics. In recent research, we showed how molecular biology methods and whole cell approaches can be integrated into new bioanalytical tools of complex assembly and how these tools are applicable for drug discovery, drug synthesis and high throughput screening. This is exemplified by the evolutive development of enzyme inhibitors for targets in chronic inflammatory diseases (cathepsin G) or cancer (CK2, hyaluronidase).

Essential hypertension (EH) is a risk factor for some severe diseases. This study aimed to screen out serum special proteins and seek interaction between them, which would provide new therapeutic targets and elucidate the comprehensive pathophysiological mechanism for EH. Patients with EH (Group A, n = 47) and healthy controls (HC) (Group B, n = 47) were recruited in this study. Serums from the two groups were analyzed with isobaric tags for relative and absolute quantitation coupled two-dimensional liquid chromatography followed by electrospray ionization-tandem mass spectrometry technique, while the candidate special proteins were verified with ELISA and western blot. A total of 404 proteins were identified, of which 30 proteins were upregulated (>1.2-fold, p < 0.05) and 81 proteins were downregulated (<0.833-fold, p < 0.05) compared with HC group. With GO, KEGG analysis, and literature retrieval, 4 proteins, cathepsin G, transforming growth factor beta-1, hyaluronidase-1, and kininogen-1, were found jointly involved in the renin-angiotensin-aldosterone system and kallikrein-kinin system. The profiles of these 4 candidate proteins were confirmed with ELISA and western blot. The concentration variation of these 4 proteins could better predict the occurrence and illustrate the pathophysiological mechanism of EH. And their discovery may help pave the way for exploring new therapies of EH.
