To identify new agents for the treatment of American cutaneous leishmaniasis, a series of eight 1,4-bis(substituted benzalhydrazino)phthalazines was evaluated against Leishmania braziliensis and Leishmania mexicana parasites. These compounds represent a disubstituted version of the 1-chloro-4-(monoaryl/heteroarylhydranizyl)phthalazine that exhibited a significant response against L. braziliensis according to our previous findings. Two disubstituted phthalazines 3b and 3f were identified as potential antileishmanial agents against L. braziliensis parasites, exhibiting a submicromolar IC50 response of 2.37 and 7.90 mu M on the promastigote form, and of 1.82 and 4.56 mu M against intracellular amastigotes, respectively. In particular, compound 3b showed interesting responses against amastigote isolates from reference, glucantime-resistant and clinical human strains, which were by far superior to the biological response found for the glucantime drug. With regard to the toxicity results, both 3b and 3f exhibited moderate LD50 values against murine macrophages (BMDM), with good selectivity indexes on promastigotes and intracellular amastigotes of L. braziliensis. A comparison of biological response was established between the monosubstituted and disubstituted versions of these benzalhydrazino-phthalazines. Easy synthetic procedure and significant response against amastigote strains including against resistant lines made compound 3b a potential candidate for further pharmacokinetic and in vivo experiments as antileishmanial agent, and as a platform for further structural optimization. Mechanism-of-action studies and molecular docking simulations discarded to inhibition of superoxide dismutase as possible mode of action.

A one-step, 3-component vinylogous Mannich reaction of trimethylsilyloxyfuran or N-protected tert-butyldimethylsilyloxypyrrole with a variety of nitrogen-containing heterocycles in the presence of diverse electrophiles is described. The reaction products were generally obtained in high yields and as a single diastereoisomer having the (R*,R*) relative configuration based on crystallographic studies of several derivatives. Several azaheterocycles were successfully used for this reaction, such as isoquinolines, quinoline, phenanthridine, quinazoline, phthalazine, and beta-carboline, and electrophiles included acetyl chloride, methyl chloroformate, methyl chloromalonate, 2-bromobutanoyl chloride, and arylsulfonyl chlorides. The products of the vinylogous Mannich reactions were subjected to further transformations, leading to highly functionalized and stereochemically defined tetracyclic derivatives that are valuable building blocks for the preparation of natural products or medicinal agents.

The surface of Fe3O4 magnetic nanoparticles (MNPs) was modified by L-cysteine through condensation of COOH groups of L-cysteine and OH groups on the surface of Fe3O4. The -SH group of prepared Fe3O4@Cys MNPs oxidized to -SO3H group and Fe3O4@Cys-SO3H as an environmentally friendly magnetic nanoparticle was prepared. The MNPs were characterized by FT-IR, XRD, SEM and TEM studies. Then, the catalytic activity of the MNPs was evaluated as an effective and reusable catalyst for one-pot synthesis of 2H-indazolo [1,2-b] phthalazine-triones derivatives. The results show that the catalytic activity of Fe3O4@Cys-SO3H was comparable to that of other reported heterogeneous and homogeneous catalysts.
