Aqueous microwave-assisted one-pot synthesis of N-substituted rhodanines
Nitsche, Christoph,Klein, Christian D.
, p. 5197 - 5201 (2012)
Two aqueous, one-pot, microwave-assisted methods for the rapid synthesis of N-substituted rhodanines from amine substrates are described. Alkyl- and benzylamines could be converted into the corresponding rhodanines with an atom-efficient one-pot, three-step protocol based on carbon disulfide and chloroacetic acid in short reaction times and good to excellent yields. An alternative, microwave-assisted one-pot, one-step protocol using bis(carboxymethyl)trithiocarbonate in water was developed for the synthesis of N-arylrhodanines from anilines.

Herein, an efficient and sustainable one-pot, four-component access to rhodanine-oxindole derivatives is achieved by a reaction between primary amines, carbon disulfide, ethyl chloroacetate, and cyano-substituted alkenyl oxindoles. The reaction was conducted without any harsh conditions as well as exhausting workup in polyethylene glycol (PEG) as a green solvent at room temperature and delivered rhodanine-oxindole products in high yield. This publication is the first easy protocol to be reported for the rapid construction of new rhodanine-oxindole derivatives at room temperature without harsh conditions and via multicomponent reaction.

The protease of dengue virus is a promising target for antiviral drug discovery. We here report a new generation of peptide-hybrid inhibitors of dengue protease that incorporate N-substituted 5-arylidenethiazolidinone heterocycles (rhodanines and thiazolidinediones) as N-terminal capping groups of the peptide moiety. The compounds were extensively characterized with respect to inhibition of various proteases, inhibition mechanisms, membrane permeability, antiviral activity, and cytotoxicity in cell culture. A sulfur/oxygen exchange in position 2 of the capping heterocycle (thiazolidinedione-capped vs rhodanine-capped peptide hybrids) has a significant effect on these properties and activities. The most promising in vitro affinities were observed for thiazolidinedione-based peptide hybrids containing hydrophobic groups with Ki values between 1.5 and 1.8 μM and competitive inhibition mechanisms. Rhodanine-capped peptide hybrids with hydrophobic substituents have, in correlation with their membrane permeability, a more pronounced antiviral activity in cell culture than the thiazolidinediones.
Small molecule fusion inhibitors: Design, synthesis and biological evaluation of (Z)-3-(5-(3-benzyl-4-oxo-2-thioxothiazolidinylidene)methyl)-N-(3- carboxy-4-hydroxy)phenyl-2,5-dimethylpyrroles and related derivatives targeting HIV-1 gp41

By a scaffold elongation strategy, a series of (Z)-3-(5-(3-benzyl-4-oxo-2- thioxothiazolidinylidene)methyl)-N-(3-carboxy-4-hydroxy)phenyl-2, 5-dimethylpyrroles and related derivatives with a linear multi-aromatic-ring skeleton were designed, synthesized, and evaluated in HIV-1 gp41 and cellular assays. Among them, the most active compounds, 12e, 12g, and 12k with a one-carbon linker (n = 1) between the rhodanine (C) and phenyl (D) rings, exhibited very promising inhibitory potency with IC50 values of 1.8-2.6 μM and EC50 values of 0.3-1.5 μM against gp41 6-HB formation and HIV-1 replication in MT-2 cells, respectively. Additionally, they were almost equally effective against both T20-sensitive and resistant strains. The related SAR studies and molecular modeling results provided potential for further developing a new class of non-peptide small molecular fusion inhibitors targeting the HIV-1 gp41.

As a continuation of our previous work, which resulted in the identification of a new hit compound as an HIV-1 integrase inhibitor, three novel series of salicylic acid derivatives were synthesized using three versatile and practical synthetic strategies and were assayed for their capacity to inhibit the catalytic activity of HIV-1 integrase. Biological evaluations revealed that some of the synthesized compounds possess good inhibitory potency in enzymatic assays and are able to inhibit viral replication in MT-4 cells at low micromolar concentrations. Finally, docking studies were conducted to analyze the binding mode of the synthesized compounds within the DNA binding site of integrase in order to refine their structure-activity relationships. Easy as A, B, C: Three new series of salicylic acid derivatives were designed and synthesized to investigate their activity toward HIV-1 integrase. Some of these compounds were obtained with microwave-assisted procedures developed and optimized in our research group, which allowed us to rapidly generate several final compounds of high purity.

Based on the structure of HIV-1 gp41 binding site for small-molecule inhibitors, optimization of lead 2 resulted in the discovery of a new series of 2,5-dimethyl-3-(5-(N-phenylrhodaninyl)methylene)-N-(3-(1H-tetrazol-5-yl)phenyl) pyrrole compounds with improved anti-HIV-1 activity. The most active compounds 13a and 13j exhibited significant potency against gp41 6-HB formation with IC50 values of 4.4 and 4.6 μM and against HIV-1 replication in the MT-2 cells with EC50 values of 3.2 and 2.2 μM, respectively, thus providing a new starting point to develop highly potent small-molecule HIV fusion inhibitors targeting gp41.

experimental part, p. 41 - 48 (2010/10/03)
Electrogenerated magnesium-associated cyanomethyl anions/bases obtained from the electrochemical reduction of acetonitrile and the oxidation of a sacrificial magnesium rod were successfully used to promote the addition of carbon disulfide to primary benzylic amines. Alkylation with ethyl 3-bromopropionate acid ester or with ethyl 2-bromoacetate acid ester yields the corresponding ring-opened carbamodithioate compounds or cyclic rhodanine derivatives, respectively. The effect of the amount of electrogenerated base on the yield of reaction was also evaluated.
