Synthesis and anticancer evaluation of novel isoxazole/pyrazole derivatives

The key intermediate 3-amino-5-methylisoxazole (1) was allowed to react with phthalic anhydride and/or maleic anhydride under different conditions to produce different isoxazole products. Schiff bases 9a-c obtained via the reaction of 1 with different aldehydes were condensed with thioglycolic acid to afford the corresponding thiazolidin-4-one derivatives 10a, b. Furthermore, condensation of the Schiff bases 9a, c with various secondary amines produced the corresponding 5-substituted pyrazole derivatives 11a-d, respectively. The anticancer activity of some of the newly synthesized compounds was evaluated against Panc-1 and Caco-2 cell lines using doxorubicin as a standard drug. Most of the tested derivatives exhibited high cytotoxic potency against Panc-1 carcinoma cell lines, but moderate to weak activity was obtained against Caco-2 cell lines.

Design of a new multi-functional catalytic system Ni/SO3H@zeolite-Y for three-component synthesis of N-benzo-imidazo- or -thiazole-1,3-thiazolidinones

In this investigation, a nanoporous zeolite-NaY supported sulfonic acid was synthesized and Ni(ii) ions were successfully stabilized on SO3H@zeolite-Y (Ni/SO3H@zeolite-Y). This novel type of zeolitic nanocomposite was characterized using various techniques including FT-IR, FE-SEM, TGA, BET and EDX. Ni/SO3H@zeolite-Y was used as a multi-functional and highly active nanocatalyst for the three-component synthesis of 3-benzimidazolyl-1,3-thiazolidin-4-ones and new 3-benzthiazoleyl-1,3-thiazolidin-4-ones via cyclocondensation of 2-aminobenzimidazole or 2-aminobenzothiazole, aromatic aldehydes and thioglycolic acid in acetone-H2O at room temperature. This economical chemical procedure has advantages such as excellent yield in short reaction times, convenient manipulation and high purity of products, applicability to a broad range of substrates, and the use of a nontoxic and heterogeneous acid catalyst with good reusability.

Novel Thiazolidin-4-ones as Potential Non-Nucleoside Inhibitors of HIV-1 Reverse Transcriptase

Background: HIV is the causative agent of Acquired Immunodeficiency Syndrome (AIDS), an infectious disease with increasing incidence worldwide. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) play an important role in the treatment of AIDS. Although, many compounds are already being used as anti-HIV drugs, research for the development of new inhibitors continues as the virus develops resistant strains. Methods: The best features of available NNRTIs were taken into account for the design of novel inhibitors. PASS (Prediction of activity spectra for substances) prediction program and molecular docking studies for the selection of designed compounds were used for the synthesis. Compounds were synthesized using conventional and microwave irradiation methods and HIV RT inhibitory action was evaluated by colorimetric photometric immunoassay. Results: The evaluation of HIV-1 RT inhibitory activity revealed that seven compounds have significantly lower Iota C-50 values than nevirapine (0.3 mu Mu). It was observed that the activity of compounds depends not only on the nature of substituent and it position in benzothiazole ring but also on the nature and position of substituents in benzene ring. Conclusion: Twenty four of the tested compounds exhibited inhibitory action lower than 4 mu Mu. Seven of them showed better activity than nevirapine, while three of the compounds exhibited IC50 values lower than 5 nM. Two compounds 9 and 10 exhibited very good inhibitory activity with IC50 1 nM.

Synthesis and Antimicrobial Screening of Novel Azetidin-2-ones Derived from Pyromellitic Diimide via [2+2]-Cycloaddition Reaction

A series of novel 2-azetidinone derivatives have been obtained starting from pyromellitic dianhydride. Pyromellitic dianhydride was converted to pyromellitic diimide using sodium cyanate, and the diimide was alkylated with ethyl chloroacetate. The resulting diester was treated with hydrazine hydrate to obtain dihydrazide which reacted with substituted pyridine-2-carbaldehydes to give the corresponding Schiff bases, and [2+2]-cycloaddition of the latter with chloroacetyl chloride in the presence of triethylamine afforded the target azetidin-2-one derivatives. The newly synthesized compounds showed high antimicrobial activities against some bacterial and fungal strains.

Synthesis and bioactivity of thiazolidin-2-cyanamide derivatives against type III secretion system of Xanthomonas oryzae on rice

Targeting virulence factors of bacterial without affecting their growth and survival, has been an initiative strategy for the development of novel anti-microbial agents. The type III secretion system (T3SS), one of essential and highly conserved virulence factors in most Gram-negative pathogenic bacteria, has been regarded as an effective target that developed new anti-microbial drugs. Xanthomonas oryzae pv. oryzae (Xoo) is one of the most Important bacterial pathogens on rice, which causes leaf blight disease. To discover potential anti-virulence agents against the pathogens, a new series of thiazolidin-2-cyanamide derivatives containing 5-phenyl-2-furan were designed and synthesized. Their structures were characterized by H-1 NMR, C-13 NMR, MS, and elemental analysis. All the title compounds inhibited the promoter activity of a harpin gene hpa1, significantly, that were further checked for the impact on bacterial growth and on the hypersensitive response (HR) caused by Xoo on non-host tobacco plants. The results indicated that treatment of Xoo with the title compounds II-2,II-3 and II-4 resulted in significantly attenuated HR without affecting bacterial growth or survival. Moreover, quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis showed that the expression of the Xoo T3SS was suppressed by treatment with the three inhibitors. The mRNA levels of representative genes in the hrp (hypersensitive response and pathogenicity) cluster, as well as the regulatory genes hrpG and hrpX, were reduced. Finally, the in vivo test demonstrated that the compounds could reduce the disease symptoms of Xoo on the rice cultivar (Oryza sativa) IR24.
