The aim. To assess pharmacotherapy of hospitalised patients with coronary heart disease in Ukraine, identify the types of drug-related problems, and recommend interventions to improve the management of cardiac inpatients.

Materials and methods. The objects of the study were 25 medical records of inpatients with coronary heart disease complicated by heart failure and atherosclerotic cardiosclerosis. Methods applied: systematisation, generalisation, comparison, clinical and pharmaceutical approach. The statistical analyses were performed using the SPSS Trial.

Results. A comprehensive retrospective study was conducted to assess the management of cardiovascular diseases. In total, 25 patients were prescribed 62 drugs. It was established that 53.5 % of medicines were "Agents affecting the cardiovascular system"; out of them, 26.9 % were "other cardiac drugs" (C01E) used for enhancing cardiac energy metabolism. The study identified 597 drug-related problems (DRPs) (23.9±12.6 DRPs per patient) with the drug-drug interactions prevalence (62.6 %). Other common groups of DRPs were: (1) no indications for drug administration (8.5 %), and (2) despite indications, the drug was not prescribed (8.2 %). 99 DRPs (16.6 %; 95 % CI:13.7-19.8 %) were associated with "other cardiac drugs". They included 4 types of DRPs: (1) no indications for drug administration (33.3 %); (2) insufficient duration of the treatment (31.3 %); (3) drug-drug interactions (22.3 %); and (4) insufficient dosage or frequency of use (13.1 %).

Conclusion. Our findings suggest that the treatment of cardiac inpatients is associated with numerous DRPs. Thus, we formed a list of recommendations to improve the management of cardiovascular diseases in hospitalised patients

Aim. Based of the Knoevenagel condensation reaction the synthesis of new rhodanine-indoline hybrid molecules for screening antibacterial and antifungal activities was accomplished. Methods. Organic synthesis, NMR spectroscopy, pharmacological screening. Results. The reaction between rhodanine-3-propanoic/ethanesulfonic acids and indolecarbaldehydes in the acetic acid provided series of 5-indolylmethylenerhodanine-3-carboxylic/sulfonic acid derivatives. Based on the esterification reaction with methanol in the presence of sulfuric acid, 5-indolylmethylenerhodanine-3-propanic acid was transformed into appropriate ester for further evaluation of antimicrobial activity. The antimicrobial activity screening allowed the identification of compounds with significant effect against Escherichia coli, Staphylococcus lentus and Candida albicans with MIC/MBC/MFC values in the range of 25-50 μg/mL.
Conclusions. The synthesized 5-indolylmethylenerhodanine-3-carboxylic/sulfonic acid derivatives are a convenient platform for the development of new highly active and low-toxic agents as potential drug-like molecules with antimicrobial activity.
K e y w o r d s: synthesis, 2-thioxo-4-thiazolidinone, indolecarbaldehydes, spectral data, antimicrobial activity.

Aim. The screening of antimicrobial and cytotoxic activities of thiazolo[4,5-b]pyridine derivatives was accomplished. Methods. The antibacterial and antifungal activities of synthesized thiazolopyridines were evaluated in vitro with the agar diffusion and broth microdilution methods using clinical and reference strains of Gram-positive, Gram-negative bacteria and yeasts. The structure-antibacterial/antifungal activity relationships of the screened compounds were established. The target compounds were screened for their cytotoxicity effects on HaCaT and HEK293 cells using MTT assay. Results. The highest antimicrobial activity was observed for compound V 2-oxo-7-thiophen-2-yl-2,3-dihydrothiazolo[4,5-b]pyridine-5-carboxylic acid with minimal inhibitory concentration (MIC) 12.5 μg/mL against Candida albicans. At the same time, the synthesized compounds were explored in the interaction with amoxicillin against multidrug resistant clinical isolates of ESβL+ Klebsiella pneumonie and Staphylococcus haemolyticus (MRSH). The best synergistic activity with amoxicillin was exhibited by compound VI. HaCaT human keratinocytes and HEK293 human embryonic kidney cells demonstrated resistance to the thiazolopyridine derivatives treatment and did not reach the IC50 value up to 100 µM. Conclusions. The tested thiazolopyridines constitute an interesting background for further development of new chemotherapeutic agents.
