A comparative study of the toxicity of two unsubstituted calixarenes consisting of 4 and 6 phenolic fragments, as well as their p-sulfated derivatives, was carried out on the HT-29 colorectal adenocarcinoma cells cultured in two-dimensional (2D) and three-dimensional (3D) formats. It was shown that both unsubstituted calixarenes decrease the viability of tumor cells; calix[4]arene and calix[6]arene exhibited a cytostatic and a cytotoxic effect, respectively. Sulfated derivatives of calixarenes did not have a pronounced toxic effect on HT-29 cells. However, due to their high hydrophilicity and the ability to form adducts with various therapeutic molecules, they can be used for delivery of anticancer drugs. calixarenes, cytotoxicity, HT-29 cells, 2D cell culture, 3D cell culture The work was financially supported by the Russian Science Foundation (project no. 19-15-00397).

Dietary phytochemicals possess a variety of biological activities which can be widely discovered in fruits, vegetables and herbs. Geraniin, an ellagitannin is commonly found in fruits and herbs which possesses multitude of health benefits including anti-diabetic, hepatoprotective, anti-inflammatory and anticancer. However, the effects of geraniin on human colorectal adenocarcinoma cells have yet to be evaluated. This study aimed to investigate the apoptotic effects of geraniin against selected human cancer cell lines and elucidate its underlying mechanisms. Geraniin exhibited the strongest cytotoxic effect on HT-29 cells as determined by MTT assay. Events of apoptosis induced by geraniin in HT-29 cells was portrayed by apoptotic morphological changes, externalization of phosphatidylserine, DNA fragmentation and dissipation of mitochondrial membrane potential. Western blot analysis was then used to investigate the mechanisms underlying observed growth inhibition. Geraniin was found to initiate p53 activation further resulting in elevation of Bak/Bcl-xL ratio and caspase-3 activation. This eventually led to HT-29 cell death via apoptosis. Additionally, exposure of geraniin on HT-29 cells found to suppress the PI3K/Akt/mTOR pathway and suppression of NF-kB. Cumulative evidences in this study suggests that geraniin inhibited colorectal adenocarcinoma cell proliferation via apoptosis induction and suppression of PI3K/Akt/mTOR pathway. Thus, these findings provide novel mechanistic insight for the therapeutic potential of geraniin in the treatment of colorectal adenocarcinoma.
