Abstract

Tuberculostatics are crucial drugs to for life expectancy, mainly to HIV-positive patients. Several reasons justify the need for new antimycobacterial, including high morbilitiy and mortality related to tuberculosis. The resurgence of multidrug resistant (MDR-TB) and extensively drug resistant (XDR-TB), typical morphophysiological features of Mycobacterium tuberculosis, as well as phenotypical forms (active and latent), also are challenge to discovery of tuberculostatics. Thus, efforts are necessary to discover and develop tuberculostatic with innovative structural and mechanistic patterns. The current project aims the synthesis and biological evaluation of isobavachalcone (IBC), a tri-hydroxylated and C-isoprenylated chalcone with potent and unexplored tuberculostatic activity. Three series of analogs of IBC will be synthesized. Series I, II and III will exhibit modifications on chalconic ring A, ring B and alpha, beta-unsaturated ketone, respectively. The synthetical strategy will include iodation and Suzuki coupling reactions (or Stille reaction and Heck reaction), allowing C-prenylation at carbon C-3' (ring A). The antimycobacterial potency will be determined against sensitive H37Rv and clinical isolates (MDR-TB and XDR-TB) strains., indicating Minimum Inhibitory Concentration (MIC) values. The n-octanol/water partition coefficient (log Po/w) will be performed by HPLC-DAD experiment, aiming to relate hydrophobicity and antimycobacterial activity of chalcones. The values of log Po/w and melting points of chalcones will be used in the prection of water-solubility (log S), by using of General Solubility Equation. Antimycobacterial compounds (MIC H37Rv < 10 uM) will be submitted to toxicity evaluations against eukaryotic cells, including murine macrophages (J774A.1), human pneumocytes (MRC-5) and human hepatocytes HepG2), stablishing selective index (IS - IC50 eukaryote/MIC H37Rv). Chalcones that exhibited SI (macrophage) > 10 will be selected to evaluation against intramacrophagic forms of Erdman M. tuberculosis. In addition, compound that activity against resistant clinical isolates will be submitted to inhibition assays of efflux pump of Mycobacterium smegmatis, as model with reduce biological risk. (AU)
