CHEMICAL PROFILING OF SUTHERLANDIA FRUTESCENS AND S. MICROPHYLLA

Sutherlandia frutescens and its taxonomic ally, S. microphylla are indigenous to southern Africa and both boast an impressive history as an ethnomedicinal plant. The uses are diverse, spanning from the use against infectious diseases to the use against wasting to the treatment of diabetes and inflammation. More recently S. frutescens has been used in the treatment of conditions associated with HIV. The various pharmacological properties are ascribed to the presence of amino acids, triterpenes and glycosides. Despite the extensive use, published scientific studies focusing on the phytochemical profile and variations are scarce. This is crucial in unravelling the scientific rationale for the past and present day uses and possibly provides valuable information to optimise harvesting protocols and could contribute to good manufacturing practices. The aerial parts of S. frutescens (n=125) and S. microphylla (n=20) were collected from natural and cultivated sites. Near infrared spectroscopy (NIRS) was used to determine to potential of this technique to distinguish between the two species. The amino acids and pinitol were quantified with high performance liquid chromatography (HPLC). High-pressure thin layer chromatography (HP-TLC) was used to assess the consistency in the chemical fingerprint for the various samples. NIRS shows no difference between the two species. This technique was however not sensitive enough to quantify the amino acid content through NIRS calibration. The quantitative variation of amino acids and pinitol within and between natural populations and individual plants in a cultivation site was noted and these results will be discussed

A Review on Pharmacy Practice in South Africa—A Higher Education Perspective

In April 1994, South Africa underwent the most significant change in its recent history with the disbandment of the policy of apartheid and the attendant race-based politics, which affected most aspects of the country and, of relevance to this review, the education, health delivery, and career choices that race groups could pursue. In the past 28 years, the South African government has tried to implement policies in order to advance political and socioeconomic shifts toward a more equitable society. The healthcare sector was an early target for transformation that was aimed at increasing access to services and the expansion of primary healthcare and hospital facilities to previously underserved areas. This paper seeks to discuss these changes in broad terms, but with specific reference to general health care and pharmacy practice in particular. It will look at the changes in the legislative framework and pharmacy education and factors impacting the pharmacy practices in South Africa over the past 28 years. A discussion of the critical issues that have affected the profession in the last three decades will also be delineated, and future prospects for the profession as a whole, in terms of pharmacy practice and perspectives, will be discussed. We review the current aspects of the pharmacy profession in South Africa today and how the education of those future professionals is a major contribution to the pharmaceutical climate

The Use of Medicinal Plant-Derived Metallic Nanoparticles in Theranostics

In the quest to effectively diagnose and treat the diseases that afflict mankind, the development of a tool capable of simultaneous detection and treatment would provide a significant cornerstone for the survival and control of these diseases. Theranostics denotes a portmanteau of therapeutics and diagnostics which simultaneously detect and treat ailments. Research advances have initiated the advent of theranostics in modern medicine. Overall, theranostics are drug delivery systems with molecular or targeted imaging agents integrated into their structure. The application of theranostics is rising exponentially due to the urgent need for treatments that can be utilized for diagnostic imaging as an aid in precision and personalised medicine. Subsequently, the emergence of nanobiotechnology and the green synthesis of metallic nanoparticles (MNPs) has provided one such avenue for nanoscale development and research. Of interest is the drastic rise in the use of medicinal plants in the synthesis of MNPs which have been reported to be potentially effective in the diagnosis and treatment of diseases. At present, medicinal plant-derived MNPs have been cited to have broad pharmacological applications and have been studied for their potential use in the treatment and management of cancer, malaria, microbial and cardiovascular diseases. The subject of this article regards the role of medicinal plants in the synthesis of MNPs and the potential role of MNPs in the field of theranostics

Iridoid Derivatives as Anticancer Agents: An Updated Review from 1970–2022

The rise of cancer cases has coincided with the urgent need for the development of potent chemical entities and/or modification of existing commodities to improve their efficacy. Increasing evidence suggests that cancer remains one of the leading causes of death globally, with colon cancer cases alone likely to rise exponentially by 2030. The exponential rise in cancer prevalence is largely attributable to the growing change toward a sedentary lifestyle and modern diets, which include genetically modified foods. At present, the prominent treatments for cancer are chemotherapy, surgery, and radiation. Despite slowing cancer progression, these treatments are known to have devastating side effects that may deteriorate the health of the patient, thus, have a low risk–benefit ratio. In addition, many cancer drugs have low bioavailability, thereby limiting their therapeutic effects in cancer patients. Moreover, the drastic rise in the resistance of neoplastic cells to chemotherapeutic agents is rendering the use of some drugs ineffective, thereby signaling the need for more anticancer chemical entities. As a result, the use of natural derivatives as anticancer agents is gaining considerable attention. Iridoids have the potential to form conjugates with other anticancer, antidiabetic, antileishmanial, and antimalarial drugs, which synergistically have the potential to increase their effects. Published studies have identified the role of iridoids, which, if fully explored, may result in cheaper and less toxic alternative/adjuvant cancer drugs. The subject of this article is natural and synthetic iridoid derivatives and their potential therapeutic roles as anticancer agents
