Recent Advances In Developing Novel Anti-Cancer Drugs Targeting Tumor Hypoxic and Acidic Microenvironments

Recent Patents on Anti-cancer Drug Discovery

Abstract

Solid tumors often contain hypoxic microenvironments due to abnormal vasculatures and outweighing demands of oxygen. Cancer cells rely on anaerobic respiration, leading to sequential acidic microenvironments. Hypoxic and acidic microenvironments cause genetic instability and activate signaling pathways, contributing to cancer progression and therapy resistance, and have become targets for developing novel anti-cancer agents. This article reviews recent advances in the development of novel anti-cancer drugs targeting hypoxic and acidic microenvironments. Recent patents and published literature related to anti-cancer agents targeting tumor hypoxic and acidic microenvironments were searched and reviewed. Key termed used in the searching included cancer, anti-cancer drug, neoplasm, clinical trials, tumor microenvironment, hypoxic microenvironment, acidic microenvironment, hypoxia-inducible factors, hypoxia; metabolism; Warburg effect and aerobic glycolysis. A number of Hypoxia-Inducible Factor (HIF) inhibitors have been developed or discovered, but most of them have only exhibited indirect effects on HIFs, and a limited number of drugs are able to directly interfere with mRNA and protein of HIFs, the dimerization of α and β subunit...Continue Reading

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.

Cancer Metabolic Reprogramming

Cancer metabolic reprogramming is important for the rapid growth and proliferation of cancer cells. Cancer cells have the ability to change their metabolic demands depending on their environment, regulated by the activation of oncogenes or loss of tumor suppressor genes. Here is the latest research on cancer metabolic reprogramming.

Cancer Metabolism: Therapeutic Targets

Targeting the mechanisms by which cancer cells acquire energy for metabolic needs is a therapeutic target. Discover the latest research on cancer metabolism and therapeutic targets.
