What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Area of Science:

Medicinal Chemistry
Chemical Biology
Drug Discovery

Background:

Natural products are essential sources of chemical diversity for molecular screening libraries.
Developing fragment screening libraries from natural products can enhance drug discovery efforts.

Purpose of the Study:

To establish a foundation for generating fragment screening libraries from natural products.
To analyze the physicochemical and structural diversity of fragment-sized natural products.

Main Methods:

Physicochemical property analysis and Principal Component Analysis (PCA) were used to select and position fragments.
Structural diversity was assessed using pharmacophore fingerprints, radial fingerprints, and scaffold analysis.
Analysis focused on small pharmacophore triplets and sp3-rich scaffolds.

Main Results:

Fragment-sized natural products capture over 50% of the pharmacophore triplet diversity found in larger natural products.
2-ring fragment scaffolds offer a balance between complexity and structural diversity.
The study identified approximately 2800 natural products across 422 clusters for a fragment library.

Conclusions:

Fragment-sized natural products are valuable starting points for diverse medicinal chemistry libraries.
This approach effectively captures key molecular interaction motifs from natural products.
The generated fragment library provides a foundation for efficient drug lead generation.
