The Department of Chemistry at the University of the Free State (UFS) held a successful online International Symposium on Organic Chemistry on 15 June 2021. The symposium brought together scientists from several South African and foreign universities and created a virtual platform for a long-awaited discussion stalled by the COVID-19 pandemic. About 20 participants from universities in South Africa, Belgium, and Germany presented their lectures during the symposium. In addition, this symposium was directed at the postgraduate students in the Department of Chemistry at the UFS, allowing them to present their results to an international audience and to foster their engagement in scientific research.

For more than a year, the COVID-19 pandemic has prevented the common personal communication avenues for the researchers: face-to-face (F2F) conferences, symposia, and workshops. To bridge this gap, Prof Vladimir Azov and Dr Charlene Marais from the Department of Chemistry organised the online meeting for the researchers from the UFS and several other local and foreign universities, all working in the field of organic chemistry.

Collaborative project between the UFS and VUB towards the development of gel-based drug release systems

The symposium also served as a long-awaited inception meeting for the collaborative project between the Organic Chemistry group at the UFS and the Organic Chemistry (ORGC) group at the Vrije Universiteit Brussel (VUB). This project is jointly funded by the National Research Foundation (NRF) and FWO (Research Foundation – Flanders); it is aimed at the development of new peptide-based materials with properties controllable by precisely tuned interactions of unnatural amino acids included in the peptide sequence. Such peptides can, for example, be used as smart materials for precisely controllable drug release. The South African team members, directed by Prof Vladimir Azov, will specialise in the development of the new amino acid building blocks, whereas the VUB team, headed by Prof Ulrich Hennecke, will focus on peptide preparation and studies on their properties.

This kick-off meeting was initially planned as a F2F event in June 2020 but was delayed due to the COVID-19 travelling restrictions and finally migrated to a virtual space. This provided an opportunity to present the project proposals and to discuss the initial results in a much broader circle than would have been possible within the common F2F meeting framework.

Science is diversifying the uses of traditional medicines

According to the World Health Organisation, a large majority of the African population are making use of traditional medicines for health, socio-cultural, and economic purposes. In Africa, up to 80% of the population uses traditional medicines for primary healthcare.

The Indigenous Knowledge Systems (IKS) was identified as a lead programme under the directorship of Dr Motlalepula Matsabisa. Research undertaken by the IKS Lead Programme focuses on some key priority diseases of the country and region – including malaria, HIV, cancer, and diabetes.
 
Not just a plant or tree

Malaria is a priority disease and is prevalent in rural and poor areas, resulting in many traditional health practitioners claiming to treat and cure the disease. There may well be substance to these claims, since as much as 30% of the most effective current prescription medicines are derived from plants.  For instance, chloroquine, artemisinin for malaria, Metformin for diabetes, Vincristine and Vinblastine for cancer, are plant-derived drugs.  

Dr Matsabisa’s current research is investigating a South African medicinal plant that has been shown to have in vitro antiplasmodial activity, with subsequent isolation and characterisation of novel non-symmetrical sesquiterpene lactone compounds offering antimalarial activity. These novel compounds are now patented in South Africa and worldwide. This research is part of the UFS and South Africa’s strive to contribute to the regional and continental malaria problem. The UFS are thus far the only university that has been granted a permit by the Medicines Control Council to undertake research on cannabis and its potential health benefits.

“All of these projects are aimed
at adding value through the scientific
research of medicinal plants, which
can be used for treating illnesses,
diseases, and ailments.”

Recognition well deservedThrough Dr Matsabisa’s research input and contributions to the development of the pharmacology of traditional medicines, he recently became the first recipient of the International Prof Tuhinadrin Sen Award from the International Society of Ethnopharmacology (ISE) and the Society of Ethnopharmacology in India. ISE recognises outstanding contributions by researchers, scientists, and technologists in the area of medicinal plant research and ethnopharmacology internationally.

More recently, Dr Matsabisa undertook research projects funded by the National Research Foundation, as well as the Department of Science and Technology, on cancer, gangrene, and diabetes. He is also involved in a community project to develop indigenous teas with the community. He says, “All of these projects are aimed at adding value through the scientific research of medicinal plants, which can be used for treating illnesses, diseases, and ailments”.

Dr Matsabisa has worked with many local and international scientists on a number of research endeavours. He is grateful to his colleagues from the Department of Pharmacology in the Faculty of Health Sciences, who are dedicated to science research and the research of traditional medicines. The IKS unit also received immense support from the Directorate of Research Development.
