Over the last decade, a significant body of research has been developed around the inclusion of a metallocene moiety into known antimalarial compounds. Ferroquine is the most successful of these compounds. Herein, we describe our contribution to metallocene antimalarials. Our approach has sought to introduce diversity sites in the side chain of ferroquine(More)
To establish the role of the ferrocenyl moiety in the antiplasmodial activity of ferroquine, compounds in which this moiety is replaced by the corresponding ruthenium-based moieties were synthesized and evaluated. In both the sensitive (D10) and resistant (K1) strains of Plasmodium falciparum, ruthenoquine analogues showed comparable potency to ferroquine.(More)
It is widely accepted in the higher education literature that a student-centred approach is pedagogically superior to a teacher-centred approach. In this paper, we explore the notion of student-centredness as a threshold concept and the implications this might have for academic staff development. We argue that the term student-centred in the Rogerian sense(More)
Synthesis of the potent antiplasmodial 4-aminoquinoline, phenylequine (PQ), is reported for the first time. PQ and the two analogues show increased efficacy in moving from the chloroquine sensitive D10 to the chloroquine resistant K1 strain in vitro. The in vivo efficacy of PQ, and salts thereof, have been determined in Plasmodium berghei ANKA and(More)
Research into metal complexes of known antimalarial drugs have been known for 30 years. Initial exploration into this field was fairly slow and largely limited to the synthesis of the complexes and reporting of antiplasmodial efficacy. In the last five years this approach has shifted substantially. Increasingly papers dealing with the mechanism of action,(More)
With the emergence of resistance to artemesinin, the need for new antimalarial compounds is pressing. Several research groups have made significant contributions to the exploration of the use of 1,2,4,5-tetraoxanes and 1,2,4- trioxanes as synthetic analogues of artemesinin. This short review highlights the recent developments in this field detailing both(More)
7-Chloroquinoline-based antimalarial drugs are effective in the inhibition of hemozoin formation in the food vacuole of the Plasmodium parasite, the causative agent of malaria. We synthesized five series of ferroquine (FQ) and phenylequine (PQ) derivatives, which display good in vitro efficacy toward both the chloroquine-sensitive (CQS) NF54 (IC50 : 4.2 nm)(More)
In a previous communication we described a series of indole based NNRTIs which were potent inhibitors of HIV replication, both for the wild type and K103N strains of the virus. However, the methyl ether functionality on these compounds, which was crucial for potency, was susceptible to acid promoted indole assisted SN1 substitution. This particular problem(More)
Malaria continues to affect millions of people annually. With the rise of drug resistant strains, the need for alternative treatments has become increasingly urgent. Recently, PfUCHL3 was identified as an essential deubiquitinating enzyme. The increasing number of drug target structures being solved has increased the feasibility of utilizing a structural(More)
The synthesis and in vitro evaluation of novel triazole-linked chloroquinoline derivatives as potential antiplasmodial agents against Plasmodium falciparum is reported. The 15 synthesized target compounds were obtained by means of a copper(I)-mediated click reaction between a variety of 1,2- and 1,3-azidoamines and(More)
