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.

Synthesis, Structural, and Theoretical Studies of Quinazoline-2,4-dione Derivatives

New quinazolin-2,4-dione derivatives have been synthesized and fully characterized. The new derivatives were synthesized using 3-(2-imino-4-oxo-3H,4H,5H-thiazolidin-3-yl)-1H-quinazolin-2,4-dione by nucleophilic addition mechanism. DFT calculations using B3LYP/6-311++G(d,p) level of the theory were used to investigate the molecular structures and the relative stabilities of the anticipated isomers (E and Z). Both experimental and theoretical calculations confirmed the higher stability of the Z-isomers compared to the E-isomers. The former is stabilized by two intramolecular hydrogen bonds compared to only one in the latter isomer. The frontier orbital calculations (HOMO and LUMO), and the energy gap confirmed the stability of the molecules.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 137-40-6, in my other articles.

One-pot synthesis of 1,3-thiazolidin-4-one using ammonium persulfate as catalyst

Ammonium persulfate can be used as a homogeneous catalyst for three-component one-pot synthesis of some 1,3-thiazolidin-4-one derivatives from aldehydes, amines and mercaptoacetic acid under solvent-free conditions with good yields. The characterization of products was generally achieved by IR and NMR techniques. Inexpensive catalyst, high yields, simple product isolation and high atom economy are the noteworthy aspects of the protocols.

Dose-related antihyperglycemic and hypolipidemic effects of two novel thiazolidin-4-ones in a rodent model of metabolic syndrome

BackgroundThe replacement of the thiazolidinedione moiety with a thiazolidinone may yield antidiabetic compounds with similar pleiotropic effects. Hence, the aim of the present study was to explore the dose-related antihyperglycemic and hypolipidemic effects of two synthesized novel thiazolidin-4-one derivatives, one with a nicotinamide and the other with a p-chlorophenoxyacetamide substitution at the N3 position of the thiazolidinone ring (NAT1 and PAT1, respectively), in a rodent model of metabolic syndrome (MetS). MethodsMetabolic syndrome was induced in Wistar rats by neonatal administration of monosodium glutamate (i.p.) on 4 consecutive days followed by high-sucrose diet feeding for 6months. The effects of NAT1 (33 and 66mg/kg) and molar equivalent doses of PAT1 (40 and 80mg/kg) on relevant biochemical parameters were evaluated. Because MetS is a state of chronic low-grade inflammation, we also evaluated the effects of these compounds on proinflammatory markers, namely interleukin (IL)-6, tumor necrosis factor (TNF)-, reactive oxygen species (ROS), and nitric oxide (NO). ResultsBoth NAT1 and PAT1 attenuated hyperglycemia, hypertriglyceridemia, hypoalphalipoproteinemia, and glucose intolerance. PAT1 exhibited superior antihyperglycemic and antihypoalphalipoproteinemic effects than NAT1. However, NAT1 had a better triglyceride-lowering effect. At the lower dose tested, both compounds significantly reduced elevated malondialdehyde levels. In addition, PAT1 (80mg/kg) restored hepatic superoxide dismutase enzyme levels. There was a tendency for NAT1 and PAT1 to inhibit elevated hepatic IL-6 and TNF- levels, but the differences did not reach statistical significance. In addition, PAT1 exhibited in vitro anti-inflammatory activity by reducing proinflammatory ROS and NO levels in RAW264.7 macrophages. ConclusionsThe novel thiazolidin-4-ones NAT1 and PAT1 could be potential pleiotropic drug candidates targeting MetS.

Crystal structure of 2-[(3aS,6R)-3,3,6-trimethyl-3,3a,4,5,6,7-hexahydro-2H-indazol-2-yl]thiazol-4(5H)-one

The title compound, C13H19N3OS, is a new thiazolidin-4-one derivative prepared and isolated as the pure (3aS,6R)-diastereisomer from (R)-thiosemicarbazone pulegone. It crystallized with two independent molecules (A and B) in the asymmetric unit. The compound is composed of a hexhydroindazole ring system (viz. a five-membered dihydropyrazole ring fused to a cyclohexyl ring) with a thiazole-4-one ring system attached to one of the pyrazole N atoms (at position 2). The overall geometry of the two molecules differs slightly, with the mean planes of the pyrazole and thiazole rings being inclined to one another by 10.4 (1)degrees in molecule A and 0.9 (1)degrees in molecule B. In the crystal, the A and B molecules are linked via C-H center dot center dot center dot O hydrogen bonds, forming slabs parallel to the ab plane. There are C-H center dot center dot center dot pi interactions present within the layers, and between the layers, so forming a three-dimensional structure.

Synthesis, Biological Evaluation and Molecular Modeling Studies of New 2,3-Diheteroaryl Thiazolidin-4-Ones as NNRTIs

In a focused exploration, thiazolidin-4-ones with different C-2 and N-3 substituent groups were synthesized and evaluated as non-nucleoside reverse transcriptase inhibitors against HIV-1. This has led to new active compounds sporting heteroaryls at both C-2 and N-3 positions prompting to view them in the backdrop of nevirapine. To assign the molecular attributes for the activity, the compounds are investigated by docking them into non-nucleoside inhibitor-binding pocket of HIV-1 reverse transcriptase (RT). The most active compounds of this series (7d and 7f) shared spatial features with nevirapine with added molecular flexibility. Furthermore, in molecular dynamics simulations carried out for up to 10 ns, the compounds 7d and 7f showed consistency in their interactions with non-nucleoside inhibitor-binding pocket of HIV-1 RT and suggested Tyr319 and Val106 as potential residues for H-bond interaction with these molecules. These results open new avenues for the exploration of 2,3-diheteroaryl thiazolidin-4-ones for prevention of HIV-1.

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.
