- The exploration and exploitation of podophyllin formulations provide an example of how a plant extract with established ethnomedical use, but also causing toxicity, can provide a basis for new drug discovery and development. Applications and potential applications include the treatment of venereal warts, psoriasis, rheumatoid arthritis, malaria and Alzheimer's disease. This review addresses the history and pharmacological action of these natural products and outlines the preclinical development and clinical trials of drugs in the pipeline and with marketing approval.

Molecular Pharmacognosy : an explanatory model
- 1997

Forskningsöversikt (refereegranskat)abstract
- Increased interest in the study of natural products as potential drugs and rapidly changing research strategies are driving us to reassess the role of pharmacognosy in the wider context of pharmaceutical research. The authors propose a new definition and an explanatory model of modern pharmacognosy that can be used as a theoretical foundation for future development of this classical branch of the life sciences.

Microwave-assisted high-speed chemistry : a new technique in drug discovery
- 2001
-
Ingår i: Drug Discovery Today. - Uppsala Univ, Uppsala Biomed Ctr, Dept Organ Pharmaceut Chem, SE-75123 Uppsala, Sweden.. - 1359-6446 .- 1878-5832. ; 6:8, s. 406-416

- In both lead identification and lead optimization processes there is an acute need for new organic small molecules. Traditional methods of organic synthesis are orders of magnitude too slow to satisfy the demand for these compounds. The fields of combinatorial and automated medicinal chemistry have been developed to meet the increasing requirement of new compounds for drug discovery; within these fields, speed is of the essence. The efficiency of microwave flash-heating chemistry in dramatically reducing reaction times (reduced from days and hours to minutes and seconds) has recently been proven in several different fields of organic chemistry. We believe that the time saved by using focused microwaves is potentially important in traditional organic synthesis but could be of even greater importance in high-speed combinatorial and medicinal chemistry.

Anticancer drugs of tomorrow : apoptotic pathways as targets for drug design
- 2003

- Apoptosis or programmed cell death is a set of ordered events that enables the selective removal of cells from tissue and is essential for homeostasis and proper function of multicellular organisms. Components of this signaling network, which include ligands, such as CD95, tumor necrosis factor (TNF) and TNF-related apoptosis-inducing ligand, as well as downstream molecules, such as caspases, Bcl-2 family members, and inhibitor-of-apoptosis proteins, which trigger and regulate apoptosis, are crucial targets for conventional drug development and gene therapy of cancer and other diseases. Here, we focus on apoptotic pathways and propose new potential molecular targets that could prove effective in controlling cell death in the clinical setting.

Unconventional natural sources for future drug discovery

- ‘There are more things between heaven and earth…’ Despite the progress of science during the past four centuries, Shakespeare's words did not lose their actuality. Knowledge about the etiology of diseases is still limited, and for many life-threatening illnesses no effective treatments exist. Nature always has been a valuable source of drugs and, despite the unprecedented opportunities afforded by medicinal chemistry, continues to deliver lead compounds. Traditionally, research on natural sources was focused on terrestrial plants and microorganisms. More recently, however, organisms of marine origin are also being investigated. Here, the possibilities of unconventional and hardly explored sources are discussed.

Exploring the chemical space of orally bioavailable PROTACs
- 2024
-
Ingår i: Drug Discovery Today. - : Elsevier. - 1359-6446 .- 1878-5832. ; 29:4
-
Forskningsöversikt (refereegranskat)abstract
- A principal challenge in the discovery of proteolysis targeting chimeras (PROTACs) as oral medications is their bioavailability. To facilitate drug design, it is therefore essential to identify the chemical space where orally bioavailable PROTACs are more likely to be situated. To this aim, we extracted structure-bioavailability insights from published data using traditional 2D descriptors, thereby shedding light on their potential and limitations as drug design tools. Subsequently, we describe cuttingedge experimental, computational and hybrid design strategies based on 3D descriptors, which show promise for enhancing the probability of discovering PROTACs with high oral bioavailability.

Open for collaboration : an academic platform for drug discovery and development at SciLifeLab

- The Science for Life Laboratory Drug Discovery and Development (SciLifeLab DDD) platform reaches out to Swedish academia with an industry-standard infrastructure for academic drug discovery, supported by earmarked funds from the Swedish government. In this review, we describe the build-up and operation of the platform, and reflect on our first two years of operation, with the ambition to share learnings and best practice with academic drug discovery centers globally. We also discuss how the Swedish Teacher Exemption Law, an internationally unique aspect of the innovation system, has shaped the operation. Furthermore, we address how this investment in infrastructure and expertise can be utilized to facilitate international collaboration between academia and industry in the best interest of those ultimately benefiting the most from translational pharmaceutical research - the patients.

Telomerase activation as a possible mechanism of action for psychopharmacological interventions.
- 2015
-
Ingår i: Drug Discovery Today. - : Elsevier BV. - 1878-5832 .- 1359-6446. ; 20:11, s. 1305-1309
-
Forskningsöversikt (refereegranskat)abstract
- Originally studied in relation to aging and cancer research, telomerase is now also investigated in relation to psychiatric disorders and treatments. Based on emerging clinical and preclinical data, we hypothesise that telomerase activation could represent a novel element mediating the mechanism of action of certain psychopharmacological interventions (e.g. antidepressants, lithium and antipsychotics). The modulation of intracellular Wnt/β-catenin or PI3K/Akt signalling pathways, the interaction with BDNF and 5-HT, and the antioxidant properties could represent possible mechanisms by which the different types of psychiatric medications could modulate telomerase activity. The potential of telomerase in promoting cellular survival and/or function in the brain and in the periphery could, in turn, represent a neurobiological substrate through which the enzyme can mediate the therapeutic effect of such interventions.

Potential effects of increased openness in pharma : the original knowledge behind new drugs
- 2019
-
Ingår i: Drug Discovery Today. - : Elsevier BV. - 1359-6446 .- 1878-5832.
-
Tidskriftsartikel (refereegranskat)abstract
- This study seeks to determine potential changes in the degree of openness in pharmaceutical R&D by investigating where the knowledge behind new molecular entities (NMEs) comes from in terms of type of organization, geography and time. We find that the organizations granted NMEs increasingly rely on external knowledge sources but that these are increasingly shared among NME grantees. Universities are the most important indirect knowledge contributor and their relative importance has increased with time. NME grantees are increasingly relying on knowledge from different countries and the age of the knowledge sources confirms that recent NMEs are mostly follow-on drugs. This work provides evidence of the increasing openness of pharma to new knowledge sources as a means to improving the drug discovery and development process.
