A library of acylhydrazone iron chelators was synthesized and tested for its ability to inhibit the growth of a chloroquine-resistant strain of Plasmodium falciparum. Some of these new compounds are significantly more active than desferrioxamine DFO, the

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.

Abstract Schiff base derivatives have recently been shown to possess antimicrobial activity, and these derivatives include a limited number of salicylaldehyde hydrazones. To further explore this structure-activity relationship between salicylaldehyde hydrazones and antifungal activity, we previously synthesized and analyzed a large series of salicylaldehyde and formylpyridinetrione hydrazones for their ability to inhibit fungal growth of both azole-susceptible and azole-resistant species of Candida. While many of these analogs showed excellent growth inhibition with low mammalian cell toxicity, their activity did not extend to azole-resistant species of Candida. To further dissect the structural features necessary to inhibit azole-resistant fungal species, we synthesized a new class of modified salicylaldehyde derivatives and subsequently identified a series of modified pyridine-based hydrazones that had potent fungicidal antifungal activity against multiple Candida spp. Here we would like to present our synthetic procedures as well as the results from fungal growth inhibition assays, mammalian cell toxicity assays, time-kill assays and synergy studies of these novel pyridine-based hydrazones on both azole-susceptible and azole-resistant fungal species.
