1. Bioassay Development for Identification of Cyclooxygenase-2 Inhibitors of Natural Origin
Sammanfattning : To examine cyclooxygenase-2 (COX-2) inhibitory effects of natural compounds and structurally related compounds, a radiochemical assay for measuring inhibition of COX-2 and COX-1 catalysed prostaglandin biosynthesis was optimised. That process resulted in the development of a reliable assay for finding COX-2 inhibitors in plants, and for investigating plant constituents pertaining to the inhibition of COX-2 and COX-1. LÄS MER
2. Exploring evolutionary and chemical space using chemoinformatic tools and traditional methods in pharmacognosy
Sammanfattning : The number of new drugs coming to the market is declining while interest in lead discovery from natural resources is seeing a revival. Although methods for isolation and identification of natural products have advanced tremendously, methods for selection of potential leads have fallen behind. LÄS MER
3. Sex, Molecules, and Gene control : Ecophysiological and evolutionary aspects of key sponge species from Antarctic shallow waters and the deep sea
Sammanfattning : Very little is known about the ecophysiological aspects of Porifera (sponges) from Antarctica and North Atlantic, even though they are keystone components of these habitats. Being the earliest diverging metazoan lineage, sponges also play a fundamental role in our understanding of animal evolution. LÄS MER
4. LL-37-derived cyclic antimicrobial drug leads : Design, synthesis, activity and different ways of creating them
Sammanfattning : In an era where last-line antibiotics are failing, one of the powerful approaches to develop novel therapeutic agents is to turn back to nature in order to identify possible drug candidates. Among the potential candidates, antimicrobial peptides (AMPs) have garnered much attention as an antimicrobial. LÄS MER
5. ChemGPS-NP and the Exploration of Biologically Relevant Chemical Space
Sammanfattning : Chemical space is basically infinite, and comprises all molecules that could possibly exist. Intelligent ways to efficiently navigate through chemical space and to select promising compounds in drug discovery are important tasks, and the focus of this thesis. In this work a new model for chemical space navigation, ChemGPS-NP, was developed. LÄS MER
