Acylhydrazones 1a-o, derived from isoniazid, were synthesized and evaluated for Myeloperoxidase (MPO) and Acetylcholinesterase (AChE) inhibition, as well as their antioxidant and metal chelating activities, with the purpose of investigating potential multi-target profiles for the treatment of Alzheimer's disease. Synthesized compounds were tested using the 2,2-diphenyl-2-picrylhydrazyl (DPPH) method and 1i, 1j and 1 m showed radical scavenging ability. Compounds 1b, 1 h, 1i, 1 m and 1o inhibited MPO activity (10 μM) at 96.1 ± 5.5%, 90 ± 2.1%, 100.3 ± 1.7%, 80.1 ± 9.4% and 82.2 ± 10.6%, respectively, and only compound 1 m was able to inhibit 54.2 ± 1.7% of AChE activity (100 μM). Docking studies of the most potent compound 1 m were carried out, and the computational results provided the theoretical basis of enzyme inhibition. Furthermore, compound 1 m was able to form complexes with Fe2+ and Zn2+ ions in a 2:1 ligand:metal ratio according to the Job Plot method.

Background: Despite availability of variety of antibacterial agents, re-emergance of pathogenic bacteria is still a serious medical concern. Identification of new, safer, and selective antibacterial agents is the key interest in the medicinal chemistry research. Methods: A library of synthetic arylidene nicotinic and isonicotinic hydrazones (1-63) were investigated for antimicrobial activities. Results: A number of derivatives showed significant to moderate antimicrobial activities against Gram positive and Gram negative bacterial cultures. Few compounds also showed antifungal activity against fungal cultures. Minimum Inhibitory Concentration (MIC) was calculated for the most active compounds 1, 7, 11, 19, 34, 46, 50, 51, and 55 against gram positive and gram negative cultures. Conclusion: Newly identified compounds may serve as lead for future research in order to get the more powerful antibacterial agents.

Two series of pyridine derivatives were synthesised and evaluated for their in vivo anti-malarial activity against Plasmodium berghei. The anti-malarial activity was determined in vivo by applying 4-day standard suppressive test using chloroquine (CQ)-sen
