Schiff bases of 4-Phenyl-2-Aminothiazoles as hits to new antischistosomals: Synthesis, in vitro, in vivo and in silico studies

The treatment of schistosomiasis is based on a single drug, the praziquantel (PZQ), an oral bioavailable and efficient agent which causes minimal side effects. The main concern about this approach, however, is that relying on only one drug to treat a helminthic disease is a dangerous strategy since history shows that pathogens easily evolve to resistant forms. Actually, reports about experimental strains exhibiting low sensibility to PZQ can be found in literature. The search for new antischistosomals, consequently, is urgent. Here we report the synthesis of seventeen Schiff bases of 4-(4-Substituted phenyl)-N-(4-substituted benzylidene)thiazole-2-amines which were tested in vitro and in vivo against Schistosoma mansoni adult worms. Moreover, in silico studies to propose potential macromolecular targets and to predict the oral bioavailability were also performed. The analog GPQF-108 exhibited the best in vitro performance (IC50: 29.4 muM, SI:6.1) associated with promising in vivo activity, with a significant decrease in the adult life forms and oviposition. Oral bioavailability could be impaired by the predicted low water solubility of GPQF-108, although it also exhibited good membrane permeability. The water solubility, however, could be improved by decreasing the particles size. Serine/Threonine- and Tyrosine Kinases, Carbonic Anhydrase, Tyrosine Phosphatase and Arginase were predicted as potential macromolecular targets through which the GPQF-108 could be acting against the helminth. This class of compounds exhibited an interesting initial therapeutic profile with the advantage of being chemically diverse from the PZQ and be easily synthesized from commercial reagents which could lead to low-cost drugs. These aspects make this class of compounds interesting hits to be explored against schistosomiasis.

A new supported reagent for the parallel synthesis of primary and secondary O-alkyl hydroxylamines through a base-catalyzed Mitsunobu reaction

The growing field of applications of O-alkyl hydroxylamines in medicinal chemistry and chemical biology has motivated the search for a parallel synthesis. A solid-phase approach based on the alkylation by alcohols of a new supported N-hydroxyphthalimide reagent using a Mitsunobu reaction followed by methylaminolysis has been optimized. This study points out the importance of the linker and a specific base effect for the Mitsunobu reaction. A large variety of alcohols can be used to give with moderate to high yields diverse O-alkyl hydroxylamines in high purity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 137-00-8 is helpful to your research., Application of 137-00-8

Copper-Catalyzed Chelation-Assisted ortho-Nitration of 2-Aryls Using Pharmacophoric Benzothiazoles and Benzoxazoles as Directing Groups

A copper-catalyzed chelation-assisted ortho-nitration reaction of aryl derivtives has been achieved, using benzazoles as efficient directing groups. The reaction is general and efficient for aryl derivatives with various electronic properties, and also with different pharmacophorically important directing groups, i.e., benzoxazoles, benzothiazoles, and benzimidazoles. The nitro-group-containing products have significance as fluorogenic compounds and potential nitroreductase substrates that could be used for the detection of clinically important microorganisms. The nitration reaction proceeds with an inexpensive copper catalyst and a mild, cheap, and environmentally friendly nitro source, Fe(NO3)3·9H2O. This operationally simple and functional-group-tolerant protocol for the nitration of 2-aryl benzazoles proceeds with a high regioselectivity without the exclusion of air or moisture.

Novel anthraquinone derivatives with redox-active functional groups capable of producing free radicals by metabolism: Are free radicals essential for cytotoxicity?

The mode of action of antitumour anthraquinone derivatives (i.e. mitoxantrone) is not clearly established yet. It includes, among others, intercalation and binding to DNA, bioreduction and aerobic redox cycling. A series of anthraquinone derivatives, with potentially bioreducible groups sited in the side chain, have been synthesized and biologically evaluated. Their redox and cytotoxic activities were screened. Derivatives which bear a 2-(dimethylamino)ethylamino substituent, known to confer high DNA affinity, demonstrated cytotoxicity but not redox activity (beside the anthraquinone reduction). Conversely, derivatives which showed redox activity were not cytotoxic toward the P388 cell line. The results suggest that bioreduction is not the main mode of action in the cytotoxicity of anthraquinones.
