Abstract

Insights

The mammalian target of the rapamycin (mTOR) pathway is crucial for cancer treatment. New mTOR inhibitors show potent anticancer activity and a favorable safety profile in preclinical studies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • The mammalian target of the rapamycin (mTOR) signaling pathway regulates cell growth, survival, and angiogenesis.
  • Dysregulation of the mTOR pathway is common in cancer, making it a key therapeutic target.
  • Rapalogs like temsirolimus and everolimus are approved for specific cancers, with others in clinical trials.

Purpose of the Study:

  • To review the literature on the mTOR pathway, its inhibitors, and their role in cancer treatment.
  • To overview recent data on mTOR signaling and novel mTOR inhibitors.
  • To discuss the development status of second-generation mTOR inhibitors.

Main Methods:

  • Literature review of published data on the mTOR pathway and inhibitors.
  • Analysis of preclinical and clinical data on mTOR inhibitors in various tumors.
  • Overview of signaling pathways related to mTOR.

Main Results:

  • Preclinical data suggest new mTOR inhibitors possess potent antiproliferative activity.
  • These novel inhibitors demonstrate a favorable safety profile.
  • In preclinical studies, mTOR inhibitors achieved disease stabilization or tumor regression and enhanced other anticancer treatments.

Conclusions:

  • Published data on novel mTOR inhibitors are emerging but limited.
  • Preclinical results indicate significant potential for new mTOR inhibitors in cancer therapy.
  • Further research is warranted to fully elucidate the efficacy and safety of novel mTOR inhibitors in clinical settings.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
