New Derivatives Of Antimalarial Drug Artemisinin

INTRODUCTION         The number people stirred by malaria is change order of magnitude enormously. This increasing is due to the manufacture drug resistant variants of the poriferan that causes malaria the Plasmodium. This exemption is a outcome of the massive use of the quinoline-related drugs all over the expiry decades. In this scenario, it became authorised to attack for overbold drugs, diligent against novel biochemical parasite targets. The drug known as artemisin or Qinghaosu (1), is a burden of Chinese government campaign, to search for new active drugs against malaria, in Chinese medicinal plants. In the popular mechanism accepted for the action of artemisin, the free hematin crowd, obtained during the haemoglobin digestion is proposed to catalyse the define of oxyl thoroughgoings, by oxidation of the Fe(II) to Fe(III) and the decrement of the endoperoxide bond. These oxyl radicals rearrange in to C-centred radicals that atomic number 18 cytotoxic to the parasite by alkylation of snappy parasite proteins. In the experiments directed in Liverpool, the maiden-class honours degree measuring rod was to try to synthesise novel artemisin derivatives and consequently to do a biomimetic study, with these complicateds and the crusade flavor FeCl.

In the first experiment carried, it was try to synthesise an ether (2) of the dihydroartemisin (3) and tetrazol chloride (4), apply a method create by University of Algarve Organic Chemistry group (see plot 1) organization 1 In the following experiments, and using a variant methodology, it was tried to synthesise, with artemisin benzoate (5) and p-trifluoromethoxi phenol (6) as start material, the trifluoromethoxi phenol substituted compound (7) (see scheme 2)         Scheme 2 At last, it was d sensation a biomimetic study, reacting the obtained compound with the iron salt FeCl (scheme 3), originating two different products: the whizz resulting from the composition of a autochthonic carbon centred radical (8); and from the formation of a secondary C-centered radical (9).
