Diagnostic and prognostic value of cystatin C as an early marker of renal dysfunction in patients with cardiovascular pathology
Disorders of the kidneys often occur in cardiovascular diseases. They are connected with the heart by complex hemodynamic and neuroendocrine bonds. The structure, functions, and possibilities of using an endogenous indicator of the functional state of the kidney - cystatin C are discussed in the article. Available data allow the use of cystatin C as a predictor of renal dysfunction in patients with cardiovascular pathology and arterial hypertension, in particular. However, the widespread use of cystatin C in routine clinical practice requires further study and improvement.
Abstract Some unexpected promiscuous inhibitors were observed in a virtual screening protocol applied to select cruzain inhibitors from the ZINC database. Physical–chemical and pharmacophore model filters were used to reduce the database size. The selected compounds were docked into the cruzain active site. Six hit compounds were tested as inhibitors. Although the compounds were designed to be nucleophilically attacked by the catalytic cysteine of cruzain, three of them showed typical promiscuous behavior, revealing that false positives are a prevalent concern in VS programs.
