(ASM, 2019)Mycobacterium tuberculosis, the causative agent of tuberculosis, remains a leading infectious killer globally, demanding the urgent development of faster-acting drugs with novel mechanisms of action. Riminophenazines such ... -
In vitro efficacy of synthesized artemisinin derivatives against Leishmania promastigotes
(Elsevier, 2020)Leishmaniasis is a neglected tropical disease affecting thousands worldwide, especially in developing countries where it co-exists with malaria. Only a handful of drugs are clinically available to treat the disease, but ... -
In vitro evaluation of the cytotoxic and apoptogenic properties of aloe whole leaf and gel materials
(Taylor & Francis, 2014)Aloe gel and whole-leaf materials have shown biological effects with potential therapeutic applications, and recently, their drug-absorption enhancement properties have been discovered. It is important to establish a ... -
In vitro oral drug permeation models: the importance of taking physiological and physico-chemical factors into consideration
(Taylor & Francis, 2016)Introduction: The assessment of intestinal membrane permeability properties of new chemical entities is a crucial step in the drug discovery and development process and a variety of in vitro models, methods and techniques ... -
In vitro permeation of mesembrine alkaloids from Sceletium tortuosum across porcine buccal, sublingual, and intestinal mucosa
(Thieme, 2012)Sceletium tortuosum is an indigenous South African plant that has traditionally been used for its mood-enhancing properties. Recently, products containing S. tortuosum have become increasingly popular and are commonly ... -
In vitro permeation of metals through human skin: a review and recommendations
(American Chemical Society, 2015)During the last few decades, the interest in skin permeation of, specifically, metals has increased with the in vitro method utilizing diffusion cells as the prominent method of investigating permeability. This review ... -
In vitro permeation of platinum and rhodium through Caucasian skin
(Elsevier, 2014)During platinum group metals (PGMs) refining the possibility exists for dermal exposure to PGM salts. The dermal route has been questioned as an alternative route of exposure that could contribute to employee sensitisation, ... -
In vitro permeation of platinum through African and Caucasian skin
(Elsevier, 2015)The majority of the South African workforce are Africans, therefore potential racial differences should be considered in risk and exposure assessments in the workplace. Literature suggests African skin to be a superior ... -
In vitro skin permeation of artemisone and its nano-vesicular formulations
(Elsevier, 2016)The artemisinin derivative artemisone has antitumor activity. In particular when encapsulated in solid lipid nanoparticles (SLNs) and niosomes, it is active against human melanoma A-375 cells, although such formulations ... -
In vitro skin permeation of sinigrin from its phytosome complex
(Wiley, 2016)Objectives: Sinigrin is a major glucosinolate present in plants of the Brassicaceae family. Recently sinigrin and its phytosome formulations have been investigated for its wound healing actions, by our research group. The ... -
In vitro wound healing and cytotoxic activity of the gel and whole-leaf materials from selected aloe species
(Elsevier, 2017)Ethnopharmacological relevance Aloe vera is one of the most important medicinal plants in the world with applications in the cosmetic industry and also in the tonic or health drink product market. Different parts of Aloe ... -
In vitro wound healing and cytotoxic effects of sinigrin-phytosome complex
(Elsevier, 2016)Sinigrin is a class of glucosinolates found naturally in plants of the Brassicaceae family. Lately, studies have shown that sinigrin possesses anticancer, antibacterial and anti-inflammatory activities. Since its efficacy ... -
In vivo efficacy and bioavailability of lumefantrine: evaluating the application of Pheroid technology
(Elsevier, 2015)The oral absorption of compounds with low aqueous solubility, such as lumefantrine, is typically limited by the dissolution rate in the gastro-intestinal tract, resulting in erratic absorption and highly variable ... -
In vivo evaluation of acute intravenous toxicity of a [Ga-68]Ga-PSMA-11-microemulsion
