- Synthesis and biological evaluation of 1,2,3-triazole tethered thymol-1,3,4-oxadiazole derivatives as anticancer and antimicrobial agents
-
A library of 1,2,3-triazole-incorporated thymol-1,3,4-oxadiazole derivatives (6–18) hasbeen synthesized and tested for anticancer and antimicrobial activities. Compounds 7, 8, 9, 10, and 11 exhibited significant antiproliferative activity. Among these act

- Synthesis, α-glucosidase inhibition, and molecular docking studies of novel N-substituted hydrazide derivatives of atranorin as antidiabetic agents
-
A series of novel N-substituted hydrazide derivatives were synthesized by reacting atranorin, a compound with a natural depside structure (1), with a range of hydrazines. The natural product and 12 new analogues (2–13) were investigated for inhibition of α-glucosidase. The N-substituted hydrazide derivatives showed more potent inhibition than the original. The experimental results were confirmed by docking analysis. This study suggests that these compounds are promising molecules for diabetes therapy. Molecular dynamics simulations were carried out with compound 2 demonstrating the best docking model using Gromac during simulation up to 20 ns to explore the stability of the complex ligand-protein. Furthermore, the activity of all synthetic compounds 2–13 against a normal cell line HEK293, used for assessing their cytotoxicity, was evaluated.

- Design, synthesis, biological screenings and docking simulations of novel carvacrol and thymol derivatives containing acetohydrazone linkage
-
Abstract: Carvacrol and thymol are well-known phenolic monoterpenoids present as functional ingredients in numerous products. Keeping the diverse therapeutic activities of phenolic monoterpenes in mind, we attempted to synthesize a new series of acetohydrazone linkage containing carvacrol and thymol derivatives. All synthesized derivatives were characterized by spectroscopic techniques. Finally, all the derivatives were screened for their anti-oxidant activities by using DPPH assay, and anticancer activities by using SRB assay against pancreatic cancer with the MIAPaCa-2 cell line and colon cancer with the HCT-15 cell line. Themolecular docking studies of all the synthesized derivatives were carried out on the cyclooxygenase-2 (COX-2) protein enzyme. In the anti-oxidant test, EC50 values of all the compounds showed excellent anti-oxidant potency, and similarly the values of GI50 in the anticancer test displayed that most of the compounds possess good anticancer potency. Total docking results suggested that all the synthesized compounds exhibit good binding affinity towards receptors.

- Synthesis and antiproliferative evaluation of novel 2-(4H-1,2,4-triazole-3-ylthio)acetamide derivatives as inducers of apoptosis in cancer cells
-
In this study, a series of thiosemicarbazide derivatives 12–14, 1,2,4-triazol-3-thione derivatives 15–17 and compounds bearing 2-(4H-1,2,4-triazole-3-ylthio)acetamide structure 18–32 have been synthesized starting from phenolic compounds such as 2-naphthol, paracetamol and thymol. Structures and purity of the target compounds were confirmed by the use of their chromatographic and spectral data besides microanalysis. All of the synthesized new compounds 12–32 were evaluated for their anti-HIV activity. Among these compounds, three representatives 18, 19 and 25 were selected and evaluated by the National Cancer Institute (NCI) against the full panel of 60 human cancer cell lines derived from nine different cancer types. Antiproliferative effects of the selected compounds were demonstrated in human tumor cell lines K-562, A549 and PC-3. These compounds inhibited cell growth assessed by MTT assay. Compound 18, 19 and 25 exhibited anti-cancer activity with IC50values of 5.96?μM (PC-3?cells), 7.90?μM (A549/ATCC cells) and 7.71?μM (K-562?cells), respectively. After the cell viability assay, caspase activation and Bcl-2 activity of the selected compounds were measured and the loss of mitochondrial membrane potential (MMP) was detected. Compounds 18, 19 and 25 showed a significant increase in caspase-3 activity in a dose-dependent manner. This was not observed for caspase-8 activity with compound 18 and 25, while compound 19 was significantly elevated only at the dose of 50?μM. In addition, all three compounds significantly decreased the mitochondrial membrane potential and expression of Bcl-2.
