1. Sínteses de monômeros derivatizados com 3-aminopiridina contendo complexos polipiridínicos de Ru(II) do tipo cis-[RuCl2(α-diimina)] onde α-diimina: 2,2᾿-bipiridina e 1,10-fenantrolina e 5-Cl-1,10-fenantrolina / Synthesis of monomers derivatized with 3-aminopyridine containing complexes of ruthenium(II) of type cis-[RuCl2(α-diimine)]where α-diimine: 2,2᾿-bipyridine and 1,10-phenantroline and 5-Cl-1,10-phenantroline
Os monômeros ligantes 3amdpy2oxaNBE (1), 3imdpyoxaNBE (2) e ácido âmico (3) foram sintetizados e caracterizado por analise elementar (CHN), infravermelho e RMN 1H e 13C. A partir do monômero 1 sintetizou-se compostos partindo de complexos do tipo [RuCl2(LL)], onde foi LL=bpy 37 (complexo 4), phen (complexo 6) ou 5-Cl-phen (complexo 7), e foram realizados

2. Electron microscopy of complexes of isolated acetylcholine receptor, biotinyl-toxin, and avidin.
The principal curarimimetic toxin of Naja naja siamensis derivatized with biotinyl groups binds specifically both to acetylcholine receptor, isolated from Torpedo californica electric tissue, and to avidin. Isolated complexes of receptor monomer or dimer, biotinyl-toxin, and avidin were negatively stained and examined in the scanning transmission electron mi

3. Isolation of the galactose-binding lectin that mediates the in vitro adherence of Entamoeba histolytica.
Entamoeba histolytica adheres to human colonic mucus, colonic epithelial cells, and other target cells via a galactose (Gal) or N-acetyl-D-galactosamine (GalNAc) inhibitable surface lectin. Blockade of this adherence lectin with Gal or GalNAc in vitro prevents amebic killing of target cells. We have identified and purified the adherence lectin by two methods
