Abstract A progression of novel thiadiazoline spiro quinoline derivatives were synthesized from potent thiadiazoline spiro quinoline derivatives . The synthesized compounds portrayed by different spectroscopic studies and single X-ray crystallographic studies. The compounds were assessed for in vitro anticancer properties towards MCF-7 and HeLa cells. The compounds showed superior inhibition action MCF-7 malignant growth cells. Amongst, the compound 4a showed significant inhibition activity, the cell death mechanism was evaluated by fluorescent staining, and flow cytometry, RT-PCR, and western blot analyses. The in vitro anticancer results revealed that the compound 4a induced apoptosis by inhibition of estrogen receptor alpha (ERα) and G2/M phase cell cycle arrest. The binding affinity of the compounds with ERα and pharmacokinetic properties were confirmed by molecular docking studies.

Treatment of cancer patients with anthracyclin-based chemotherapeutic drugs induces congestive heart failure by a mechanism involving p53. However, it is not known how p53 aggravates doxorubicin (Dox)-induced toxicity in the heart. On the basis of in vitro acute toxicity assay using heat shock factor-1 (HSF-1) wild-type (HSF-1+/+) and HSF-1-knockout (HSF-1−/−) mouse embryonic fibroblasts and neonatal rat cardiomyocyte-derived H9c2 cells, we demonstrate a novel mechanism whereby heat shock protein 27 (HSP27) regulates transcriptional activity of p53 in Dox-treated cells. Inhibition of p53 by pifithrin-α (PFT-α) provided different levels of protection from Dox that correlate with HSP27 levels in these cells. In HSF-1+/+ cells, PFT-α attenuated Dox-induced toxicity. However, in HSF-1−/− cells (which express a very low level of HSP27 compared with HSF-1+/+ cells), there was no such attenuation, indicating an important role of HSP27 in p53-dependent cell death. On the other hand, immunoprecipitation of p53 was found to coimmunoprecipitate HSP27 and vice versa (confirmed by Western blotting and matrix-assisted laser desorption/ionization time of flight), demonstrating HSP27 binding to p53 in Dox-treated cells. Moreover, upregulation of p21 was observed in HSF-1+/+ and H9c2 cells, indicating that HSP27 binding transactivates p53 and enhances transcription of p21 in response to Dox treatment. Further analysis with flow cytometry showed that increased expression of p21 results in G2/M phase cell cycle arrest in Dox-treated cells. Overall, HSP27 binding to p53 attenuated the cellular toxicity by upregulating p21 and prevented cell death.

Oxypeucedanin (OPD), a furocoumarin compound from Angelica dahurica (Umbelliferae), exhibits potential antiproliferative activities in human cancer cells. However, the underlying molecular mechanisms of OPD as an anticancer agent in human hepatocellular cancer cells have not been fully elucidated. Therefore, the present study investigated the antiproliferative effect of OPD in SK-Hep-1 human hepatoma cells. OPD effectively inhibited the growth of SK-Hep-1 cells. Flow cytometric analysis revealed that OPD was able to induce G2/M phase cell cycle arrest in cells. The G2/M phase cell cycle arrest by OPD was associated with the downregulation of the checkpoint proteins cyclin B1, cyclin E, cdc2, and cdc25c, and the up-regulation of p-chk1 (Ser345) expression. The growth-inhibitory activity of OPD against hepatoma cells was found to be p53-dependent. The p53-expressing cells (SK-Hep-1 and HepG2) were sensitive, but p53-null cells (Hep3B) were insensitive to the antiproliferative activity of OPD. OPD also activated the expression of p53, and thus leading to the induction of MDM2 and p21, which indicates that the antiproliferative activity of OPD is in part correlated with the modulation of p53 in cancer cells. In addition, the combination of OPD with gemcitabine showed synergistic growth-inhibitory activity in SK-Hep-1 cells. These findings suggest that the anti-proliferative activity of OPD may be highly associated with the induction of G2/M phase cell cycle arrest and upregulation of the p53/MDM2/p21 axis in SK-HEP-1 hepatoma cells.

From a root bark of Lespedeza bicolor Turch we isolated two new (7 and 8) and six previously known compounds (1–6) belonging to the group of prenylated polyphenols. Their structures were elucidated using mass spectrometry, nuclear magnetic resonance and circular dichroism spectroscopy. These natural compounds selectively inhibited human drug-resistant prostate cancer in vitro. Prenylated pterocarpans 1–3 prevented the cell cycle progression of human cancer cells in S-phase. This was accompanied by a reduced expression of mRNA corresponding to several human cyclin-dependent kinases (CDKs). In contrast, compounds 4–8 induced a G1-phase cell cycle arrest without any pronounced effect on CDKs mRNA expression. Interestingly, a non-substituted hydroxy group at C-8 of ring D of the pterocarpan skeleton of compounds 1–3 seems to be important for the CDKs inhibitory activity.
