Synthesis and isomerization of acridine substituted 1,3-thiazolidin-4-ones and 4-oxo-1,3-thiazolidin-5-ylidene acetates. An experimental and computational study

Acridine thiosemicarbazones 3a-g, obtained through a two-step reaction between aromatic iso-thiocyanates and hydrazine followed by the treatment with acridin-9-carbaldehyde, in reaction with bifunctional reagents; methyl bromoacetate (MBA) and diethyl acetylenedicarboxylate (DEAD) afforded acridin-thiazolidinone derivatives 4a-g and 7a-f and not their regioisomers 6a-g and 9a-f. Derivatives 4a-g and 7a-f exhibit Z(C2N6)E(N7c8) configuration. Upon standing in DMSO-d(6) the thiazolidinones 4a-g and 7a-f spontaneously isomerized into Z(C2N6)Z(N7C8) isomers 5a-g and 8a-f to give a mixture of the both stereoisomers. All compounds were fully characterized by multinuclear NMR, mass spectrometry (MS) and X-ray crystal structure of 4b is also described. X-ray diffraction study revealed that the representative compound 4b crystallized in the monoclinic crystal system with the C2/c space group and Z = 4. Intramolecular C1′-H1′ center dot center dot center dot N-7 hydrogen bond between the acridine proton H-1′ and nitrogen N-7 of linker existed. This hydrogen bond is responsible for the E isomerism on C-8 atom which was observed in the NMR experiments. Quantum-chemical calculations and NOESY experiments confirmed Z(C2N6)Z(N7C8) configuration of the transformed stereoisomers 5a-g and 8a-f. (C) 2017 Elsevier B.V. All rights reserved.

Synthesis and antiviral activity of camphor-based 1,3-thiazolidin-4-one and thiazole derivatives as Orthopoxvirus-reproduction inhibitors

The Orthopoxvirus genus belongs to the Poxviridae family and includes variola virus (smallpox), cowpox virus, monkeypox virus and vaccinia virus (VV). Smallpox is considered one of the great epidemic disease scourges in human history. It has currently been eradicated; however, it remains a considerable threat as a biowarfare or bioterrorist weapon. The poxvirus, VV, serves as a model virus from which new antiviral therapies against Orthopoxviruses can be identified. Here, a series of nitrogen-sulphur containing heterocycles such as 1,3-thiazolidin-4-one and thiazoles containing a 1,7,7-trimethylbicyclo[2.2.1]heptan scaffold were synthesized and screened for their antiviral activity. The bioassay results showed that the 4b, 4c and 4e thiazoles, which contained a substituted benzene ring, were able to inhibit VV reproduction with IC50 values in the 2.4-3.7 micromolar range whilst exhibiting moderate cytotoxicity. Among the thiazolidin-4-one derivatives, compound 8b, which contained a 4-methylbenzylidene group, displayed good inhibitory activity (IC50 = 9.5 M) and moderate toxicity.

Transition-metal-free synthesis of thiazolidin-2-ones and 1,3-thiazinan-2-ones from arylamines, elemental sulfur and CO2

Transfering waste to treasure is highly important in green chemistry. However, it is difficult to realize it efficiently due to the low reactivity, especially the simultaneous utilization of two unreactive feedstocks in one reaction. Herein, we report the first utilization of both elemental sulfur and CO2 in a multi-component reaction to generate valuable thiazolidin-2-ones and 1,3-thiazinan-2-ones. Under transition-metal-free reaction conditions, a variety of easily available arylamines react with elemental sulfur and CO2 (1 atm) to give functional thiazolidin-2-ones and 1,3-thiazinan-2-ones in moderate to good yields via C-H bond functionalization. This strategy is highlighted by high step economy with generation of three bonds in one reaction and good functional groups tolerance.

SYNTHETIC APPROACH FOR BUILDING HETEROANNULATED FURO[3,2-g]CHROMENES USING 4,9-DIMETHOXY-5-OXO-5H-FURO[3,2-g]CHROMENE-6-CARBONITRILE AND CYCLIC CARBON NUCLEOPHILE

A novel series of polyfused heterocyclic systems containing furo[3,2-g]chromenes were efficiently synthesized. The reactivity of 4,9-dimethoxy-5-oxo-5H-furo[3,2-g]chromene-6-carbonitrile (1) was studied towards a variety of carbon nucleophilic reagents such as heterocyclic enols, heterocyclic enamines and cyclic active methylene compounds. Treatment of carbonitrile 1 with 4-hydroxycoumarin, 4-hydroxy-1-methylquinolin-2(1H)-one (3), 2-hydroxy-4H-pyrido[1,2-a]pyrimidin-4-one (4) afforded furodichromenopyridine 2, furochromenonaphthyridine 5, furochromenodipyridopyrimidine 6. Reaction of carbonitrile 1 with 4(6)-aminouracil and 5-amino-3-methyl-1H-pyrazole proceed through ring opening followed by cycloaddition into the nitrile group giving pyrido[2,3-d]pyrimidine 7 and pyrazolo[3,4-b]pyridine 8. Also, reaction of carbonitrile 1 with 5-amino-2,4-dihydro-3H-pyrazol-3-one (9), 2-(phenylimino)-1,3-thiazolidin-4-one (11), thiobarbituric acid and cyclohexane-1,3-dione produced the novel annulated furo[3,2-g]chromenes 10, 12-14, respectively. Cyclohexane-1,2-dione reacted with carbonitrile 1 in 1:2 molar ratio afforded bis-(furochromeno)[1,10]phenanthroline 15. The prepared compounds were screened in vitro for their antimicrobial activity and some of them appeared notable activity against the tested microorganisms.

Novel 2,3-disubstituted 1,3-thiazolidin-4-one derivatives as potential antitumor agents in renal cell adenocarcinoma

Cancer represents one of the main causes of mortality in developed countries. In particular, the overall survival of patients with renal cell carcinoma (RCC) remains poor and the available cytostatic agents are insufficient. Therefore, there is an urgent requirement to identify more effective and safer anticancer drugs. Recently, the evaluation of antitumor activity appeared to be promising for thiazolidinone derivatives. The present study presents the synthesis and the cytotoxicity assays of 1,3-thiazolidin-4-ones. The newly synthesized substances were screened in vitro against selected cancer human renal cell adenocarcinoma cells (769-P), human hepatoblastoma-derived cells (HepG2) and normal green monkey kidney cells (GMK) as a reference cell line. N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl]acetamide and N-[2-(4-methylphenyl)-4-oxo-1,3-thiazolidin-3-yl]benzamide displayed significant antiproliferative activity towards 769-P. To elucidate the mechanisms of the cytotoxic actions, additional studies on the cell cycle and apoptosis were performed. The aforementioned compounds were responsible for G1 cell cycle arrest and the decrease in cell distribution in the G2 phase in a dose-dependent manner, which prevents mitotic divisions of the 769-P cells. In addition, these novel 2,3-disubstituted 1,3-thiazolidin-4-ones slightly induced apoptosis in 769-P in a dose-dependent manner. It was hypothesized that the 4-methylphenyl group at position 2 of the thiazolidin-4-one scaffold may be regarded as a promising moiety for further development of this group of compounds. Therefore, benzamide moiety appeared to be crucial for triggering cells to apoptotic cell death.

Organic solar cells based on non-fullerene acceptors of nine fused-ring by modifying end groups

A series of small molecule acceptors (SMAs) based on a benzodithiophene-pyrrolobenzothiadiazole-based nine fused-ring core and different end groups of 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene) malononitrile (2FIC), 3-(dicyanomethylene)indian-1-one (IC) and 2-(3-ethyl-4-oxo-thiazolidin-2-ylidene) malononitrile (RCN) have been designed and synthesized. The SMAs X94FIC, X9IC, X9Rd and X9T4FIC were chosen as electron acceptors with blending the donor polymer PBDB-T to prepare the organic solar cells (OSCs) and investigate photoelectric performance. Surprisingly, X94FIC showed an excellent photo-response up to 1000 nm, while X9IC and X9T4FIC also possess a photo-response to 900 nm. A power conversion efficiency (PCE) of 7.08% was obtained for the active layers PBDB-T:X94FIC. This result demonstrates that small molecule acceptor containing the nine fused-ring core and the end group with di-fluorine atoms is promising candidate for the development of high performance non-fullerene OSCs.
