the current experimental study, we have synthesised new monocarbonyl curcumin analogues bearing propargyl ether moiety in their structure and evaluated for in vitro antifungal and radical scavenging activity. The antifungal activity was carried out against five human pathogenic fungal strains such as Candida albicans, Fusarium oxysporum, Aspergillus flavus, Aspergillusniger and Cryptococcus neoformans
displayed potent cytotoxic evaluations towards cancer cells by MTT assay in terms of half-maximal inhibitory concentration of compound required to inhibit cell viability. Most of the screened derivatives (7a-i) demonstrated moderate to promising cytotoxic activity. Some of the derivatives, predominantly like 7d, 7g and 7i are the major compounds which shown promising cytotoxic activity with lower IC50 value

Abstract A new and efficient approach for the synthesis of 2,4,5-triaryl-1H-imidazoles linked 1,4-disubstitued 1,2,3-triazoles have been developed by multicomponent condensation with Huisgen 1,3-dipolar cycloaddition. A mixture of aromatic propargylated aldehydes, different azides, benzil, and ammonium acetate were condensed in the presence of catalytic amounts of acidic ionic liquid, 1-methylimidazolium
The 1‐[(1H‐1,2,3‐Triazol‐4‐yl)methoxy]phenyl}‐1H‐pyrazolo[1,2‐b]phthalazine‐5,10‐dione derivatives 5 were synthesized by a simple and efficient method, i.e., by the four‐component, one‐pot condensation reaction of phthalohydrazide 4, a (propargyloxy)benzaldehyde 1, an active methylene compound 3 (malononitrile or ethyl cyanoacetate), and an azide 2 in the presence of Cu(OAc)2/sodium L‐ascorbate as
