In the present study, a series of twelve thiazolyl hydrazone derivatives of 1-indanone was synthesized and characterized by various spectroscopic techniques such as UV-Visible, NMR, IR and Mass Spectrometry. All the synthesized target compounds were subjected to MTT assay for cytotoxicity screening and evaluation of their anti-cancer activity on various cell lines of human cancer including glioblastoma (SNB-19), prostate cancer (PC-3), Lung cancer (NCI-H460), human ovarian carcinoma (SK-OV-3 and IGROV-1), human leukemia (K-562) and human colon cancer(HCT116).Three synthesized compounds showed promising anti-cancer activity against the colon cancer cell HCT 116 cells with IC50 ranging from 1.25and#177;0.02 to 5.04and#177;0.2 and#181;M. On the other hand all the compounds didn’t show cytotoxic activity against other forms of human cancer cells.
Colorectal cancer is a major health problem, and it is the third most diagnosed cancer in the United States. The current treatment for colorectal cancer includes irinotecan, a topoisomerase I inhibitor, and other targeted drugs, such as bevacizumab and regorafenib. The low response rates and incidence of high toxicity caused by these drugs instigated an evaluation of the anticancer efficacy of a series of 13 thiazolyl hydrazone derivatives of 1-indanone, and four compounds among them show favorable anticancer activity against some of the tested colorectal cancer cell lines with IC50 values ranging from 0.41 ± 0.19 to 6.85 ± 1.44 μM. It is noteworthy that one of the indanone-based thiazolyl hydrazone (ITH) derivatives, N-Indan-1-ylidene-N’-(4-Biphenyl-4-yl-thiazol-2-yl)-hydrazine (ITH-6), has a better cytotoxicity profile against p53 mutant colorectal cancer cells HT-29, COLO 205, and KM 12 than a p53 wild-type colorectal cancer cell line, such as HCT 116. Mechanistic studies show that ITH-6 arrests these three cancer cell lines in the G2/M phase and induces apoptosis. It also causes a rise in the reactive oxygen species level with a remarkable decrease in the glutathione (GSH) level. Moreover, ITH-6 inhibits the expression of NF-κB p65 and Bcl-2, which proves its cytotoxic action. In addition, ITH-6 significantly decreased tumor size, growth rate, and tumor volume in mice bearing HT-29 and KM 12 tumor xenografts. Moreover, CRISPR/Cas9 was applied to establish an NF-κB p65 gene knockout HT-29 cell line model to validate the target of ITH-6. Overall, the results suggest that ITH-6 could be a potential anticancer drug candidate for p53 mutant colorectal cancers.
