Synthesis of Novel 2,3-Disubstituted Quinazolin-4-(3H)-ones and Their Antibacterial Activity on the Ultra-structure of Some Pathogenic Microorganisms

A SERIES of highly functionalized quinazolin-4-ones, with different substituents at position 3, have been concisely synthesized in good yields, via the reactions of 3-amino-6-bromo-2-undecyl-quinazoline-4(3H)-one with one carbon donor phenyl isothiocyante, followed by alpha-chlorinated compounds and 1,2-dichloroethanone. Moreover, reactions of 6-bromo-2-undecyl-4H-benzo-[3,1] oxazin-4-one with different hydrazides were also examined, giving new 3-substituted quinazolin-4-one derivatives. Some of the new quinazolin-4-ones were screened against gram negative and positive bacteria and showed good to moderate antibacterial activity. Structures of all new synthesized compounds in this investigation were substantiated using spectroscopic IR, H-1-NMR and MS studies.

Synthesis and Anticancer Evaluation of Thiazacridine Derivatives Reveals New Selective Molecules to Hematopoietic Neoplastic Cells

Aim and Objective: Cancer has become one of the leading causes of morbidity and mortality worldwide. Limitations associated with existing agents increase the need to develop more effective anticancer drugs to improve the therapeutic arsenal available. The aim of this study was to synthesize and evaluate the antiproliferative effects of three new thiazacridine derivatives. Material and Methods: Using a three steps synthesis reaction, three novel thiazacridine derivatives were obtained and characterized: (Z)-5-acridin-9-ylmethylene-3-(4-methyl-benzyl)-4-thioxo-thiazo-lidin-2- one (LPSF/AC-99), (Z)-5-acridin-9-ylmethylene-3-(4-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-119)and(Z)-5-acridin-9-ylmethylene-3-(3-chloro-benzyl)-4-thioxo-thiazolidin-2-one (LPSF/AC-129). Toxicity and selectivity assays were performed by colorimetric assay. Then, changes in cell cycle and cell death induction mechanisms were assessed by flow cytometry. Results: All compounds exhibited cytotoxicity to Raji ( Burkitt’s lymphoma) and Jurkat (acute T cell leukemia) cells, where LPSF/AC-119 showed best IC50 values (0.6 and 1.53 mu M, respectively). LPSF/AC-129 was the only cytotoxic compound in glioblastoma cell line NG97 (IC50 = 55.77 mu M). None of the compounds were toxic to normal human cells and induced neoplastic cell death primarily by apoptosis. Conclusion: All derivatives were more cytotoxic to hematopoietic neoplastic cells when compared to solid tumor derived cells. All three compounds are promising for in vivo and combination therapy studies against cancer.

A computational study of regioselectivity in beta-lactam iminothiazolidinone formation

Density functional theory calculations were performed to explain the different regioselectivity for the formation of p-lactam iminothiazolidinones. Computational results were in agreement with experimental observations that phenyl and cyclohexyl derivatives led to the thermodynamically more stable regioisomers formed by cyclization at the nitrogen atom directly attached to the beta-lactam ring which was in contrast to the n-hexyl derivative where the regioisomer with the beta-lactam ring attached to the imino bond is more stable instead. It was demonstrated that the different regioselectivity was the consequence of larger steric effects when bulky substituents and the leaving ethoxy group were in close contact during the cyclization step.

All the newly obtained thiazolidin-4-ones have been fully characterized by HRMS and H-1 and C-13 (1D and 2D) NMR spectroscopy. Two of them, i.e. 2 and 3, were identified by single-crystal X- ray crystallography, confirming the synthetic pathway and the spectroscopic analyses. In 3, there are two roughly identical molecules within the asymmetric unit with the same absolute configuration. These two molecules are linked through N-H center dot center dot center dot O hydrogen bonds, building an R-2(2)(8) graph-set motif.

Design, synthesis and immunomodulating activity of C-pseudonucleosides containing thiazolidin-4-one and phenyl connected by acetamide bond

Several novel C-pseudonucleosides containing thiazolidin-4-one and phenyl connected by acetamide bond were rationally designed and easily synthesized at room temperature by using the unprotected sugar aldehyde as the starting material. The effects of the compounds on Con A-induced T cell proliferation were evaluated at five concentrations of 5, 10, 25, 50, and 100 mu mol/L Interestingly, compounds 7a and 8a = 2, R = H) exhibited immunostimulating activities, while compounds 5a, 6a (n = 1, R = H) and 7b, 8b (n = 2, R = CH3) showed immunosuppressive activities. Another two compounds 5b and 6b (n = 1, R = CH3) had no immunomodulating activities. These initial biological results suggested that subtle structural changes to the phenyl and acetamide bond of C-pseudonucleosides could have a significant effect on T cell proliferation bias, although it was difficult to formulate a rigorous structure activity relationship based on the observed activities.

Synthesis of tetracyclic iminosugars fused benzo[e][1,3]thiazin-4-one and their HIV-RT inhibitory activity

Several aza-C-pseudonucleosides bearing 1,3-benzothiazin-4-one (6 and 7) were prepared by the one-pot three-component condensation from the iminosugar aldehyde 3, amino acid ethyl/methyl ester hydrochlorides 4(a-c), and 2-mercaptobenzoic acid 5. After removal of Boc and the isopropylidene groups, the target novel tetracyclic iminosugars fused benzo[e][1,3]thiazin-4-one 1(a-c) and 2(a-b) were first afforded by the intramolecular cyclo-amidation reaction. Their structures were determined by their H-1, C-13 NMR, and HRMS (ESI) spectra and X-ray. The tetracyclic iminosugars 1(a-c) and 2(a-b) were examined for their HIV reverse transcriptase (RT) inhibitory activities. The result showed that all compounds could effectively inhibit RT activity. Among them, compound 2a was the best one with the IC50 value of RT inhibitory activity of 0.82 mu M. Structure-activity relationship analysis suggested that 1’R configuration in the tetracyclic azasugars was of benefit to their anti-HIV RT activity. (C) 2016 Elsevier Ltd. All rights reserved.
