Insights

Myeloid cell leukemia-1 (MCL-1) is crucial for cancer cell survival. New small molecule BH3 mimetics targeting MCL-1 protein-protein interactions show promise in cancer therapy by restoring apoptosis.

Area of Science:

  • Oncology
  • Molecular Biology
  • Drug Discovery

Background:

  • Cancer cells evade apoptosis, a programmed cell death process.
  • Myeloid cell leukemia-1 (MCL-1) is an anti-apoptotic protein in the BCL-2 family, crucial for cancer cell survival and treatment resistance.
  • The balance of pro- and anti-apoptotic protein interactions regulates cell death.

Purpose of the Study:

  • To review the current state of MCL-1 inhibitors.
  • To highlight the discovery and medicinal chemistry of MCL-1 inhibitors.
  • To emphasize structure-based drug design and biological evaluations of these inhibitors.

Main Methods:

  • Review of recent literature on MCL-1 inhibitors.
  • Focus on structure-based drug design (SBDD) strategies.
  • Analysis of biological evaluations of small molecule BH3 mimetics targeting MCL-1.

Main Results:

  • Significant progress in developing small molecule BH3 mimetics targeting MCL-1.
  • Multiple MCL-1 inhibitor candidates have entered clinical trials.
  • Structure-based drug design has been instrumental in optimizing inhibitor potency and selectivity.

Conclusions:

  • MCL-1 inhibitors represent a promising therapeutic strategy in oncology.
  • Targeting MCL-1 protein-protein interactions offers a viable approach to overcome cancer treatment resistance.
  • Continued research in medicinal chemistry and SBDD is vital for advancing MCL-1 targeted therapies.

Protein-protein Interfaces02:04

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Targeted Cancer Therapies02:57

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...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
