Quinoline-based thiazolidinone heterocycles exhibited potent activity in the field of cancer therapy. Hence, ten quinoline-based thiazolidinone derivatives were evaluated for their anticancer activity through cytotoxic activity, epidermal growth factor receptor (EGFR) inhibition pathway, apoptosis investigation through flow cytometric analyses, RT-PCR gene expression, in vivo solid-Ehrlich carcinoma model, and finally in silico approach for highlighting the interaction pose. Results revealed that compound 7 exhibited cytotoxic activity against HCT-116 cells with an IC50 value of 7.43 µM compared to 5-FU (IC50  = 11.36 µM) with moderate cytotoxic activity against the FHC (IC50  = 35.27 µM), and it exhibited remarkable inhibition activity of EGFR with IC50 value of 96.43 nM compared to Erlotinib (IC50  = 78.65 nM). Moreover, it significantly stimulated apoptotic colon cancer cell death with 171.58-fold arresting cell cycle at G2 and S-phases. Additionally, it ameliorated both biochemical and histochemical structures near normal with tumor inhibition ratio of 52.92% compared to 5-FU of 57.16%, with immunohistochemical examinations of EGFR inhibition in the treated group compared to control. Finally, molecular docking study highlig...Continue Reading

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
