“…Several anticancer drugs usually result in the course of cell cycle arrest at a particular checkpoint, which results in the induction of the apoptotic process. [46][47][48][49] To evaluate the cell cycle profile of HT-1080 cells after treatment with the selected compounds, we performed cell cycle analysis by flow cytometry. For this study, HT-1080 cells were incubated with 10 μM of the compounds 2 b and 7 b for 24 hours (Figure 5).…”

Herein, we report the synthesis of a novel series of βhimachalene derivatives, including semicarbazones, thiosemicarbazones, and thiazoles. The structures of these compounds were elucidated by NMR, IR, and HRMS analysis methods. The in vitro antitumor activity of these compounds was evaluated by the MTT assay against four human cancer cell lines, such as fibrosarcoma (HT-1080), breast adenocarcinoma (MCF-7 and MDA-MB-231), and lung carcinoma (A-549), and the results indicated that all compounds showed moderate to significant cytotoxic activities against all cancer cell lines with IC 50 values ranging from 7.19 � 0.30 to 50 μM. The mechanism of action of the most cytotoxic compounds 2 b and 7 b suggested that they induced apoptosis through caspase-3/7 activation, and elicited G2/M-phase arrest with the loss of mitochondrial membrane potential in HT-1080 cells. The molecular docking showed that compounds 2 b and 7 b activated the caspase-3 by forming a stable protein-ligand complex.

“…Meanwhile, ligand 10 showed more affinity towards the caspase‐3 with a free energy of binding of −9.07 kcal/mol, which following the obtained experimental results. Indeed, alongside the after‐mentioned interactions for ligand 9 , substituted N‐phenyl 10 showed two additional hydrogen bonds with amino acids Cys163 and Gln161, which are essential for caspase‐3 activation [34,35,37] . The study of interactions showed that each pharmacophore of compounds 9 and 10 interacted with amino acids of caspase‐3 proteins.…”

“…To further examine the potential of the selected compounds in inducing growth inhibition of HT‐1080 cells via alternations in cell cycle arrest, we evaluated the effect of 9 and 10 on the cell cycle progression. Thus, HT‐1080 lines were incubated with 20 μM of 9 and 10 for 24h, then analyzed by the flow cytometry analysis [34] . The DNA histograms and cell cycle phase distribution are exposed in Figure 5.…”

A series of novel 2‐iminothiazolidin‐4‐one analogs have been synthesized from limonaketone, and structurally characterized by HR‐MS, 1H‐NMR and 13C‐NMR spectroscopy techniques, and the structure of compound 4 was elucidated by XRD. The newly synthesized products were biologically evaluated in vitro for their cytotoxic activity against human cancer cell lines HT‐1080, A549, and MCF‐7. Thiazolidinones 9 and 10 were the most active compounds in HT‐1080 cell lines (IC50=15.85±1.75 and 16.13±1.55 μM, respectively). The apoptosis induction of the derivatives 9 and 10 were studied using annexin V staining, caspase‐3/7 activity and cell cycle analysis. Compound 10 showed the highest ability of apoptosis induction and caspase‐3/7 activation associated with S‐phase growth arrest in HT‐1080. Meanwhile, compound 9 has a moderate apoptotic effect and G0/G1‐phase arrest in the after‐mentioned cell. The molecular docking suggested that compounds 9 and 10 formed stable ligand‐caspase‐3 complexes. Besides, the presence of phenyl moiety in ligand 10 is responsible for the enhancement of the caspase‐3 activation by the apparition of two additional hydrogen bonds with Cys163 and Gln161amino acids.

Aseries of novel 1,4-disubstituted 1,2,3-triazoles were synthesized from an (R)-carvone terminal alkyne derivative via a Cu (I)-catalyzed azide–alkyne cycloaddition reaction using CuSO4,5H2O as the copper (II) source and sodium ascorbate as a reducing agent which reduces Cu (II) into Cu (I). All the newly synthesized 1,2,3-triazoles 9a–h were fully identified on the basis of their HRMS and NMR spectral data and then evaluated for their cell growth inhibition potential by MTS assay against HT-1080 fibrosarcoma, A-549 lung carcinoma, and two breast adenocarcinoma (MCF-7 and MDA-MB-231) cell lines. Compound 9d showed notable cytotoxic effects against the HT-1080 and MCF-7 cells with IC50 values of 25.77 and 27.89 µM, respectively, while compound 9c displayed significant activity against MCF-7 cells with an IC50 value of 25.03 µM. Density functional calculations at the B3LYP/6-31G* level of theory were used to confirm the high reactivity of the terminal alkyne as a dipolarophile. Quantum calculations were also used to investigate the mechanism of both the uncatalyzed and copper (I)-catalyzed azide–alkyne cycloaddition reaction (CuAAC). The catalyzed reaction gives complete regioselectivity via a stepwise mechanism streamlining experimental observations. The calculated free-energy barriers 4.33 kcal/mol and 29.35 kcal/mol for the 1,4- and 1,5-regioisomers, respectively, explain the marked regioselectivity of the CuAAC reaction.
