Trypanosoma cruzi, the causative agent of Chagas’ disease, exhibits two different developmental stages in mammals, the amastigote, an intracellular form that proliferates in the cytoplasm of host cells, and the trypomastigote, an extracellular form that circulates in the bloodstream. We have already established an in vitro culture system using mammalian host cells (HeLa) infected with T. cruzi in which the time course of parasite growth is determined quant. We adopted this system for the screening of anti-T. cruzi agents that would ideally prove to be effective trypanosomes with no toxicity to the host cell. Of the purine analogs tested, allopurinol markedly inhibited the growth of amastigotes in a dose-dependent manner, with no lethal effect on trypomastigotes. 3′-Deoxyinosine and 3′-deoxyadenosine also suppressed T. cruzi growth inside the host cell, with the concentrations causing 50% growth inhibition being 10 and 5 μM, resp., in contrast to a concentration causing 50% growth inhibition of 3 μM for allopurinol. Among the pyrimidine analogs examined, 3′-azido-3′-deoxythmidine (zidovudine) significantly reduced the growth of the parasite at concentrations as low as 1 μM. The anti-human immunodeficiency virus agents 2′,3′-dideoxyinosine and 2′,3′-dideoxyadenosine caused a decrease in amastigote growth, while 2′,3′-dideoxycytidine and 2′,3′-dideoxyuridine had no inhibitory effect. When Swiss 3T3 fibroblasts were used as host cells, allopurinol, 3′-deoxyinosine, 3′-deoxyadenosine, and 3′-azido-3′-deoxythymidine also markedly inhibited T. cruzi proliferation. These results indicate that our culture system is useful as a primary screening method for candidate compounds against T. cruzi on the basis of two criteria, namely, intracellular replication by the parasite and host-cell infection rate. This study involved multiple reactions and reactants, such as 9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0Application of 13146-72-0).
9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. Oxidations have also proved to be valuable and efficient approaches to chiral tetrahydrofuran derivatives.Application of 13146-72-0
