چکیده

A series of new 3-Aryl-4-(4-methoxyphenyl)-1-phenyl-4,5-dihydro-1H-pyrazole-5-carbonitriles (1) were screened in vitro for their antibacterial and antifungal activities against four different organisms. The minimal inhibitory concentration (MIC’s) was determined against each organism. The compounds were tested for their antioxidant activity and reducing power ability. The effect of substitution on the activity, and the possible structure activity relationship mechanism of the compounds for their antioxidant activity are presented.

Synthesis of Novel Fluorene Bisamide Derivatives via Ugi Reaction and Evaluation their Biological Activity against Mycobacterium species

A series of new fluorene bisamide derivatives were synthesized through multi-component Ugi reaction and tested for their in vitro anti-mycobacterial activity. The structures of the products 5a-w were deduced from their IR, 1H NMR, and 13C NMR spectra. Elemental analyses (CHN) for novel compounds (5a, 5d, 5f, 5h, 5k, 5l, 5p, 5s, 5t, 5v, 5w) was done to. These compounds were evaluated as anti-bac...
