Changes in the epidemiological situation of multidrug-resistant tuberculosis in Poland in 2018-2022.

Introduction: The presented analysis was conducted against the background of the global pandemic and the Russian-Ukrainian war. The conflict on Poland's eastern border in particular raised concerns that the epidemiological situation in Poland would deteriorate due to the influx of immigrants from countries with a high incidence of MDR-TB and Beijing genotype.

Objectives: To assess the epidemiological situation of MDR-TB in Poland in 2018-2022 and to analyse the prevalence of the Beijing genotype in the Polish and immigrant populations.

Identification of Coumarin-Chalcone and Coumarin-Pyrazoline Derivatives as Novel Anti- Agents.

Introduction: Toxoplasmosis, a zoonotic infection caused by the apicomplexan parasite , affects a significant portion of the global human population. This condition, particularly dangerous for pregnant women and immunocompromised individuals, currently lacks effective treatment options.

Methods:  Eighteen coumarin-based derivatives were synthesized, comprising coumarin-chalcone hybrids (5a-i) and coumarin-pyrazoline hybrids (6a-i).

Benzenesulfonohydrazide-tethered non-fused and fused heterocycles as potential anti-mycobacterial agents targeting enoyl acyl carrier protein reductase (InhA) with antibiofilm activity.

Because resistant variants of the disease are always emerging, tuberculosis is a global issue that affects economies. New antitubercular medications should be developed, and this can be done by inhibiting druggable targets. Enoyl acyl carrier protein (ACP) reductase (InhA) is a crucial enzyme for the survival of (MTB).

Identification of 2-(-aryl-1,2,3-triazol-4-yl) quinoline derivatives as antitubercular agents endowed with InhA inhibitory activity.

The spread of drug-resistant tuberculosis strains has become a significant economic burden globally. To tackle this challenge, there is a need to develop new drugs that target specific mycobacterial enzymes. Among these enzymes, InhA, which is crucial for the survival of , is a key target for drug development.

Discovery of new quinoline derivatives bearing 1-aryl-1,2,3-triazole motif as influenza H1N1 virus neuraminidase inhibitors.

Sporadically and periodically, influenza outbreaks threaten global health and the economy. Antigen drift-induced influenza virus mutations hamper antiviral drug development. Thus, a novel antiviral agent is urgently needed to address medication inefficacy issues.
