Summary
Lactulose, a sugar, shows potential as a novel scaffold for developing galectin inhibitors. This research reveals its binding affinity and structural interactions, paving the way for new cancer therapies.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Galectins are carbohydrate-binding proteins implicated in cancer progression, including metastasis and immune evasion.
- Targeting galectin-carbohydrate interactions requires specific inhibitors, but suitable scaffolds are limited.
Purpose of the Study:
- To investigate lactulose as a novel inhibitor scaffold for galectins.
- To elucidate the molecular interactions between lactulose and galectin-1/galectin-3.
- To propose lactulose derivatives as potential anti-cancer agents.
Main Methods:
- Thermodynamic evaluation to assess binding affinity.
- X-ray crystallography to determine complex structures.
- Molecular modeling to design novel derivatives.
Main Results:
- Lactulose demonstrated binding affinity for the galectin-1 and galectin-3 carbohydrate recognition domains.
- Crystal structures revealed the precise molecular basis of lactulose-galectin interactions.
- Molecular modeling identified potential lactulose derivatives as potent anti-cancer agents.
Conclusions:
- Lactulose serves as a promising scaffold for designing specific galectin inhibitors.
- Understanding these interactions is crucial for developing targeted cancer therapies.
- Novel lactulose derivatives warrant further investigation as anti-cancer drugs.

27.9K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

10.5K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

2.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
