Exploring the impact of mitochondrial-targeting anthelmintic agents with GLUT1 inhibitor BAY-876 on breast cancer cell metabolism.

Background: Cancer cells alter their metabolic phenotypes with nutritional change. Single agent approaches targeting mitochondrial metabolism in cancer have failed due to either dose limiting off target toxicities, or lack of significant efficacy in vivo. To mitigate these clinical challenges, we investigated the potential utility of repurposing FDA approved mitochondrial targeting anthelmintic agents, niclosamide, IMD-0354 and pyrvinium pamoate, to be combined with GLUT1 inhibitor BAY-876 to enhance the inhibitory capacity of the major metabolic phenotypes exhibited by tumors.

Synthesis and Biological Evaluation of Telmisartan Alkylamine Derivatives as Potential Anticancer Agents.

Background/aim: Telmisartan is an angiotensin II receptor type 1 (AT1) antagonist with anticancer properties against solid and hematological cancer cell lines. Using telmisartan as a template, we developed alkylamine derivatives with reduced AT1 activity but increased anticancer activity.

Materials And Methods: Synthesis of candidate compounds was carried out via hexafluorophosphate benzotriazole tetramethyl uronium coupling reaction, then their inhibition of cell proliferation was determined via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and colony-formation assay was carried out on the lead candidate compound Cell death via apoptosis or necrosis by compound was determined by flow cytometry using annexin V and propidium iodide, tolerability dosing was carried out in ICR mice, and tumor-reduction properties were determined in an MDA-MB-231 xenograft model.

Synthesis and biological evaluation of benzofuran piperazine derivatives as potential anticancer agents.

This work describes about the synthesis and evaluation of substituted benzofuran piperazines as potential anticancer agents. The synthesized candidates have been evaluated for their cell proliferation inhibition properties in six murine and human cancer cell lines. In vitro evaluation of apoptosis and cell cycle analysis with the lead candidate 1.

Synthesis and biological evaluation of N, N-dialkylcarboxy coumarin-NO donor conjugates as potential anticancer agents.

A series of nitric oxide (NO) donor furoxan conjugates of N, N-dialkylcarboxy coumarins have been synthesized as potential anticancer agents. The synthesized compounds have been tested for their in vitro antiproliferative activities on various cancer and noncancerous cell lines. The candidate derivatives exhibit selectivity towards cancer cells with excellent activities in low nM to µM concentrations.

Synthesis and biological evaluation of a novel anticancer agent CBISC that induces DNA damage response and diminishes levels of mutant-p53.

A novel nitrogen mustard CBISC has been synthesized and evaluated as an anticancer agent. CBISC has been shown to exhibit enhanced cell proliferation inhibition properties against mutant p53 cell lines colorectal cancer WiDr, pancreatic cancer (MIAPaCa-2 and PANC-1), and triple negative breast cancer (MDA-MB-231 and MDA-MB-468). In vitro mechanism of action studies revealed perturbations in the p53 pathway and increased cell death as evidenced by western blotting, immunofluorescent microscopy and MTT assay.
