Zusammenfassung: | Due to the important role of monocytes/macrophages in the pathogenesis of AIDS, potential drugs with anti-HIV activity in lymphocytes must also be effective in monocytes/macrophages. For testing the efficacy of antiviral substances, monocytes/macrophages from peripheral blood were infected, respectively, with highly replicating HIV1 and HIV2 strains, thereby providing an extremely sensitive system of testing. Azidothymidine was found to inhibit both HIV types at 0.04 μg/ml. The polysulphated polyxylan, Hoe/Bay-946 (MW 6,000 Daltons), which acts through a different mechanism and is being tested in clinical pilot studies in Germany, was also found to be effective against HIV1 and HIV2 in macrophages at concentrations of 10–50 μg/ml.
En raison du rôle important des monocytes/macrophages dans la pathogenèse du SIDA, les substances anti-VIH potentiellement actives en culture de lymphocytes pourraient être aussi actives dans les monocytes/macrophages. Afin d'évaluer l'efficacité antivirale, un test très sensible a été mis au point, comprenant l'infection des monocytes/macrophages de sang périphérique par des souches de VIH1 et VIH2 de pouvoir réplicatif élevé. L'azidothymidine inhibe les deux types de VIH, à la concentration de 0,04 μg/ml. Le polyxylane polysulphaté, Hoe/Bay-946 (6.000 daltons), qui agit selon un mécanisme différent et qui est utilisé dans une étude clinique pilote en RFA, est actif contre les VIH1 et 2 dans les macrophages à la concentration de 10–50 μg/ml. |
