A series of semicarbazone and thiosemicarbazone-tailed hybrids comprising pyrazole and acetylisoxazoline were prepared from (R)-carvone and characterized by technique spectroscopies Nuclear Magnetic Resonance (NMR), IR and High-Resolution Mass Spectrometry. Density Functional Theory (DFT) determined the structural parameters. Their cytotoxic activity was evaluated against four human cancer cell lines. All the studied semi and thiosemicarbazone demonstrate a promising potential as anticancer agents. The mechanism of action of these compounds involves apoptosis in HT-1080 cells, supported by an increase in the level of caspase-3/7 activity, which also arrests the cell cycle in the G0/G1 phase. Molecular docking studies were performed to establish the potential of the most active compounds and . ADMET analysis showed appropriate pharmacokinetic properties, allowing structure prediction for anticancer activity.

In this work, a novel series of quinoline-thiosemicarbazone-1,2,3-triazole-aceamide derivatives 10a-n as new potent α-glucosidase inhibitors was designed, synthesized, and evaluated. All the synthesized derivatives 10a-n were more potent than acarbose (positive control). Representatively, (E)-2-(4-(((3-((2-Carbamothioylhydrazineylidene)methyl)quinolin-2-yl)thio)methyl)-1H-1,2,3-triazol-1-yl)-N-phenethylacetamide (10n), as the most potent entry, with IC = 48.

Tyrosinase, a key protein in the biosynthesis of melanin pigments, is crucial in determining skin pigmentation. Inhibiting tyrosinase activity is a promising approach for treating conditions related to excessive pigmentation. For the synthesis of more potent tyrosinase inhibitors, we combined two approaches, para-substitution and lipophilicity, to enhance the inhibitory properties of ()-2-(4-hydroxybenzylidene)hydrazine-1-carbotiamide, whose enzyme inhibitory properties have been previously demonstrated.

Background: The addition of IV triapine to chemoradiation appeared active in phase I and II studies but drug delivery is cumbersome. We examined PO triapine with cisplatin chemoradiation.
Methods: We implemented a 3 + 3 design for PO triapine dose escalation with expansion, starting at 100 mg, five days a week for five weeks while receiving radiation with weekly IV cisplatin for locally advanced cervical or vaginal cancer.
