Synthesis and antibacterial studies of 2-aryl-3-alkanamido-4H-thiazolidin-4-one derivatives

A series of 2-aryl-3-alkanamido-4H-thiazolidin-4-ones were synthesized from long chain fatty acid hydrazides and studied for their in vitro antibacterial activity. Long chain fatty acid hydrazides 1 on reaction with different aromatic aldehydes in the presence of catalytic amount of glacial acetic acid yielded the corresponding aryl hydrazones 2 which on further reaction with thioglycolic acid in the presence of anhydrous zinc chloride furnished the title compounds 3. These compounds were characterized by CHN analyses, IR, mass and H-1 NMR spectral data. All the compounds were evaluated for their in vitro antibacterial activity against two Gram positive strains (Bacillus subtilis and Staphylococcus aureus) and two Gram negative strains (Escherichia coli and Pseudomonas aeruginosa) and their minimum inhibitory concentration (MIC) were determined.

Antimicrobial activity of some novel 2-( 2-iodophenylimino)-5-arylidenethiazolidin-4-one derivatives

Background: Infectious diseases, especially those caused by multidrug-resistant bacteria, are becoming a serious problem worldwide because of the lack of effective therapeutic agents. Moreover, most antifungal drugs exhibit low efficacy and high toxicity because of the similarity between fungal and human cells. These issues warrant the search for potential new agents. Objectives: To synthesize potent 2-(2-iodophenylimino)-5-arylidenethiazolidin-4-one derivatives, improve the synthetic process, elucidate their structures, and determine their antimicrobial activity. Methods: 2- Iodoaniline was used as an initial reactant in a 3-step process for the synthesis of 2-(2-iodophenylimino)5-arylidenethiazolidin-4-one derivatives, including an acylation reaction, a cyclization reaction, and aldol condensation reactions. The structures of the obtained derivatives were investigated and elucidated using spectral methods. Antimicrobial activity toward 5 bacterial strains and 2 fungal strains was determined using Kirby-Bauer and agar dilution methods. Results: We successfully synthesized 12 novel compounds and elucidated their structures. The derivatives had no antifungal activities. By contrast, they showed remarkable antibacterial activities. Some of them with minimum inhibitory concentrations (MICs) <= 8 mu g/mL in both Staphylococcus aureus and methicillin-resistant S. aureus. Conclusions: A simple and flexible way to synthesize new compounds with a thiazolidin-4-one ring was determined. Some of these new compounds have outstanding effects with low MICs for bacteria. Their further investigation as therapeutic agents is warranted.

Synthesis and characterization of polymer-anchored transition metal complexes

The reaction between polystyrene 3-formylsalicylate and 2-aminophenol in DMF in the presence of ethyl acetate results in the formation of polystyrene N-(2-hydroxypheny1)-2′-hydroxybenzylideneimine-3′-carboxylate (I). Reacting with mercaptoacetic acid, a benzene suspension of I undergoes cyclization and fauns polystyrene N-(2-hydroxyphenyl)-C-(3′-carboxy-2′-hydroxyphenyl) thiazolidin-4-one, PSCH2-LH2 (II). A DMF suspension of II reacts with Zn(II), Co(II), Cu(II), Zr(OH)(2)(IV) and MoO2(VI) ions and forms the corresponding polystyrene-anchored coordination compounds, [PSCH2-LHZn(OAc)(DMF)] (III), [PSCH2-LHCo(OAc)(DMF)] (IV), [PSCH2-LHCu(OAc)(DMF)] (V), [PSCH2-LHZr(OH)(3)(DMF)(2)] (VI) and [PSCH2-LHMoO2(acac)] (VII), respectively. The polystyrene-anchored coordination compounds were characterized on the basis of elemental analyses, spectral (IR, reflectance, ESR) studies and magnetic susceptibility measurements. II acts as a monobasic bidentate OS donor ligand in all coordination compounds. The acetato groups behave as monodentate ligands in all compounds. A tetrahedral structure for III, a square-planar structure for IV and V, a pentagonal-bipyramidal structure for VI and an octahedral structure for VII are suggested.

Molecular docking, design, synthesis and biological evaluation of novel 2,3-aryl-thiazolidin-4-ones as potent NNRTIs

Nonnucleoside reverse transcriptase inhibitors (NNRTIs) remain the most promising anti-AIDS agents that target the HIV-1 reverse transcriptase enzyme (RT). However, the efficiency of approved NNRTI drugs has decreased by the appearance of drug-resistant viruses and side effects upon long-term usage. Thus, there is an urgent need for developing new, potent NNRTIs with broad spectrum against HIV-1 virus and with improved properties. In this study, a series of thiazolidinone derivatives was designed based on a butterfly mimicking scaffold consisting of a substituted benzothiazolyl moiety connected with a substituted phenyl ring via a thiazolidinone moiety. The most promising derivatives were selected using molecular docking analysis and PASS prediction program, synthesized and evaluated for HIV-1 RT inhibition. Five out of fifteen tested compounds exhibited good inhibitory action. It was observed that the presence of Cl or CN substituents at the position 6 of the benzothiazole ring in combination with two fluoro atoms at the ortho-positions or a hydrogen acceptor substituent at the 4-position of the phenyl ring are favourable for the HIV RT inhibitory activity.

Preparation of some novel thiazolidinones, imidazolinones, and azetidinone bearing pyridine and pyrimidine moieties with antimicrobial activity

By aiming to design new antimicrobial agents, we prepared new series of thiazolidin-4-ones(12a-d), imidazolin-4-ones(13a-d), and azetidin-2-ones (14a-d), having pyridine and pyrimidine moieties. Chemical structures of these derivatives were elucidated by the use of spectral and elemental analyses. All the new substituted pyridopyrimidines were subjected to in vitro antimicrobial testing by estimating the zone of inhibition toward Bacillus subtilis and Staphylococcus aureus, as examples of bacterial species, in addition to Aspergillus flavus and Candida albicans, as examples of fungal species. The results of antimicrobial testing detected that all the screened derivatives displayed antibacterial effect; especially azetidin-2-one derivative, (14c), was the most active one. Regarding the antifungal potential, only thiazolidinone derivatives, 12a and 12c, and the imidazolinone, 13c, displayed inhibitory activity toward Aspergillus flavus, while all the tested compounds, 12a-d, 13a-d, and 14a-d, except 14a, produced inhibitory potential toward Candida albicans. Docking studies of the most active antimicrobial agents, 12c, 13c, and 14c, within GLN-6-P, recorded good scores with several binding interactions with the active site.

Umpolung cyclization reaction of N-cinnamoylthioureas in the presence of DBU

A novel regioselective cyclization reaction of N-cinnamoylthioureas leading to six- or five-membered heterocyclic compounds was developed. N-Cinnamoylthioureas in the presence of trifluoroacetic acid (TFA) underwent the well-established intramolecular cycloaddition reaction to give 2-imino-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-ones in good yields. On the other hand, the reaction with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) proceeded in an unprecedented umpolung cyclization fashion to afford five-membered 2-imino-1,3-thiazolidin-4-ones and/or 2-thioxoimidazolidine-4-ones. The reaction was considered to occur via a cycloadduct of DBU with the cinnamoyl moiety followed by intramolecular attack of the thiourea group.
