A series of novel coumarin derivatives carrying 1,2,4-triazole or 1,2,4-triazolo[3,4-b][1,3,4]thiadiazole moieties were prepared and evaluated in vitro as anticancer in the human colon cancer (HCT116) cell line. The derivatives 4c and 8c exhibited marked anticancer activity with IC50 values 4.363 and 2.656 µM, respectively. The molecular docking studies suggested possible interaction with tyrosine kinases (CDK2).

The chemokine receptor CXCR4 is overexpressed and functional in colorectal cancer. To investigate the role of CXCR4 antagonism in potentiating colon cancer standard therapy, the new peptide CXCR4 antagonist Peptide R (Pep R) was employed. Human colon cancer HCT116 xenograft-bearing mice were treated with chemotherapeutic agents (CT) 5-Fluorouracil (5FU) and oxaliplatin (OX) or 5FU and radio chemotherapy (RT-CT) in the presence of Pep R. After two weeks, CT plus Pep R reduced by 4-fold the relative tumor volume (RTV) as compared to 2- and 1.6-fold reductions induced, respectively, by CT and Pep R. In vitro Pep R addition to CT/RT-CT impaired HCT116 cell growth and further reduced HCT116 and HT29 clonal capability. Thus, the hypothesis that Pep R could target the epithelial mesenchyme transition (EMT) process was evaluated. While CT decreased ECAD and increased ZEB-1 and CD90 expression, the addition of Pep R restored the pretreatment expression. In HCT116 and HT29 cells, CT/RT-CT induced a population of CD133+CXCR4+ cells, supposedly a stem-resistant cancer cell population, while Pep R reduced it. Taken together, the results showed that targeting CXCR4 ameliorates the effect of treatment in colon cancer through inhibition of cell growth and reversal of EMT treatment-induced markers, supporting further clinical studies.

A new class of 4H,5H-benzo[4,5]thiazolo[3,2-a]pyrano[2,3-d]pyrimidin-5-one and 5H,6Hpyrano[ 2,3-d]thiazolo[3,2-a]pyrimidin-5-one derivatives were synthesized via the one-pot threecomponent reaction of 2-hydroxy-4H-benzo[4,5]thiazolo[3,2-a]pyrimidin-4-one and 7-hydroxy-5Hthiazolo[ 3,2-a]pyrimidin-5-one to various aromatic aldehydes and malononitrile. This domino transformation involves the formation of pyranopyrimidine ring by the formation of three C–C bonds and one C– O bond a single synthetic operation. As the products precipitate out of the reaction, simple filtration is enough to gather the products, and thus, there is no need for work-up or column-chromatography. The synthesized thiazole/benzothiazole fused pyranopyrimidine derivatives were evaluated for their antiproliferative activity against four cancer cell lines namely DU 145 (prostate cancer), Hela (Human cervical cancer), MDA-MB-231 (breast cancer), HT-29 (Human colon cancer) and normal cell line HEK293 (human embryonic kidney cells). The results demonstrated that synthesized compounds were selective in its cytotoxicity to cancer cells compared to normal cells. Among these compounds, 2-amino-9- methoxy-5-oxo-4-(3,4,5-trimethoxyphenyl)-4H,5H-benzo[4,5]thiazolo[3,2-a]pyrano[2,3-d]pyrimidine- 3-carbonitrile 4i exhibited the most potent antiproliferative activity against the tested cell lines. Molecular docking studies revealed that these active heterocyclic molecules bind selectively in the colchicine binding site of tubulin polymer.

Objective: The objective of the study was to perform in silico molecular docking and in vitro anticancer studies of proposed 1,2,4-triazole derivatives for the determination of their anticancer activity. Methods: A series of 10 triazole compounds with different substituents were drawn in ACD Lab ChemSketch software. Molecular and biological properties were identified using Molinspiration software. The compounds that obeyed Lipinski rule of five are subjected for pharmacokinetic parameters prediction and docking analysis. SwissDock ADME software is used for the prediction of absorption, distribution, metabolism, and elimination. Then, the compounds are docked with target enzymes in Chimera software 1.14 version. The molecular docking studies revealed favorable molecular interactions and binding energies. The compounds that showed good docking results were synthesized through wet lab synthesis and further preceded for in vitro anticancer studies. Results: Three compounds are selected for wet lab synthesis due to their good docking results compared to other compounds. The synthesized compounds are subjected to different in vitro anticancer studies and found to be having potential anticancer activity. Conclusion: The pharmacokinetic and docking studies conclude that the triazole compounds have potential as anticancer agents. The in vitro anticancer studies revealed that the triazole derivatives are having high potency of anticancer activity against pancreatic cell lines.

Colchicine Derivatives

Colchicine is a well-known compound with strong antiproliferative activity that has had limited use in chemotherapy because of its toxicity. In order to create more potent anticancer agents, a series of novel colchicine derivatives have been obtained by simultaneous modification at C7 (amides and sulfonamides) and at C10 (methylamino group) positions and characterized by spectroscopic methods. All the synthesized compounds have been tested in vitro to evaluate their cytotoxicity toward A549, MCF-7, LoVo, LoVo/DX and BALB/3T3 cell lines. Additionally, the activity of the studied compounds was investigated using computational methods involving molecular docking of the colchicine derivatives to β-tubulin. The majority of the obtained derivatives exhibited higher cytotoxicity than colchicine, doxorubicin or cisplatin against tested cancer cell lines. Furthermore, molecular modeling studies of the obtained compounds revealed their possible binding modes into the colchicine binding site of tubulin.
