The design, synthesis, and antibacterial activity of 4-alkyliden-azetidin-2-ones as new antimicrobial agents against multidrug-resistant pathogens is reported. 4-Alkyliden-azetidin-2-ones were easily obtained using an original protocol starting from 4-acetoxy-azetidinones and diazoesters. Parent compounds were further elaborated to obtain a small library of 4-alkylidene derivatives. A molecular modeling
Carboxylicacids are converted to benzothiazoles in a one-pot reaction with thionyl chloride followed by treatment with 2-aminothiophenol under acid- and catalyst-free conditions.
Synthesis and biological evaluation of 3-functionalized 2-phenyl- and 2-alkylbenzo[b]furans as antiproliferative agents against human melanoma cell line
microtubules and mitotic spindle in cell division make them attractive targets in anticancer therapy. In the present study, functionalized in 3 position 2-phenyl- and 2-alkylbenzo[b]furans were synthesized and evaluated as antitumor agents. Among the synthesized derivatives 13a, 13b and 14 exhibited the most potent antiproliferativeactivityagainst human melanoma A375 cellline with IC50 values of 2.85 µM

activity. The enzyme kinetic studies performed on syringic acidderivatives showed a potential inhibitory effect on XO ability in a competitive manner with IC50 value ranging from 07.18μM-15.60μM and SY3 was revealed as the most active derivative. Molecular simulation revealed that new syringic acidderivatives interacted with the amino acid residues SER1080, PHE798, GLN1194, ARG912, GLN 767, ALA1078

3-benzodioxole responsible for the inhibition and its metabolic derivatives were conjugated with arsenical precursors. The fabricated arsenicals were eliminated much slower in mice and maintained an efficient concentration in the blood for a longer time than that of the arsenical precursors. They also performed better in anti-proliferation by inhibiting the thioredoxin system to induce oxidative stress
