A novel series of 2-(5-methyl-1,3-diphenyl-1H-pyrazole-4-yl)-5-(5-methyl-3-phenyl-isoxazole-4-yl)-[1,3,4]-oxadiazoles were synthesized from the respective 5-methyl-N’-(5-methyl-1,3-diphenyl-1H-pyrazole-4-carbonyl)-3-phenylisoxazole-4-carbohydrazides using POCl3 at 120C or by oxidative cyclization using Burgess reagent as oxidant. Newly synthesized compounds were characterized by analytical and spectral (IR,1H NMR,13C NMR and LC?MS) methods. The synthesized compounds were evaluated for their antioxidant, antimicrobial and antidiabetic activity and were compared with standard drugs.

A simple, general and straightforward synthesis of novel spiro[oxindoline-3, 4?-isoxazolo[5, 4-b]pyrazolo[4, 3-e]pyridines] by one-pot three-component reaction of isatins, 5-aminopyrazoles and 5-aminoisoxazoles in water using p-toluenesulfonic acid monohydrate (p-TSA.H2O) as the catalyst is described. The notable advantages of the protocol are good to excellent yields, short reaction time, simple purification process involving no chromatographic technique, use of water as the solvent system, application of p-TSA.H2O as cost-effective catalyst, mild reaction conditions and operational simplicity that make the protocol highly attractive.

Based on our previous results on the ascertained potent growth inhibition effect against a panel of 60 human tumors cell lines at National Cancer Institute of Bethesda (NCI), we have synthesized a novel series of thirty-one 2-[N-methyl(R-phenyl)-aminomethyl]-3-phenyl-7-trifluoromethylquinoxalines (1-31). The lead compound 1 was previously reported to be endowed with significant inhibition against hDHFR enzyme, with a Ki of 0.2 muM. Docking studies were performed on compound 1 and here reported to predict its binding conformation to human dihydrofolate reductase (hDHFR). All compounds (1-31) were assayed versus hDHFR and human thymidylate synthase (hTS). From the screening emerged that all compounds inhibited hDHFR with Ki values included between 0.2 and 11 muM, while only a few (6, 21, 24, 27, 29) showed great activity and selectivity towards hTS. Evaluation of the anticancer activity was performed by NCI, first against the three cell line panel, and only the most active compounds (17, 21, 24, 26, 27) were evaluated on a panel of 60 human tumor cell lines. Compound 21 was the most active against all cell lines with log GI50 equal to -5.49 and log LC50 equal to -4.19 and maintained significant percent of growth inhibition on seven cancer cell lines at the concentration of 1 muM. Compound 17 was the second most active and moreover showed interesting selectivity against some cell lines (Lung cancer: A549/ATCC, Melanoma: UACC-257, Ovarian Cancer: ovcar-8 and Renal cancer: RXF 393) at all concentration examined (100-0.01 muM).

4-Aminoisoxazoles can be acylated with a wide variety of activated carboxylic acids.Hydrogenation of the resulting amides gives alpha-(acylamino)enaminones, which cyclize to 4(5)-acylimidazoles upon treatment with base.This method allows for the synthesis of acylimidazoles with a wide range of substituents at C-2.Utilization of N-substituted 4-aminoisoxazoles in the same sequence of reactions yields 1-substituted 5-acylimidazoles, a substitution pattern not otherwise easily prepared.Treatment of alpha-(acylamino)enaminones, derived from N-unsubstituted isoxazoles, with primary amines leads to incorporation of the amine at the beta-position with concomitant expulsion of ammonia.This sequence efficiently yields 1-substituted and 1,2-disubstituted 4-acylimidazoles but does not give satisfactory yields of 5-substituted 4-acylimidazoles due to steric inhibition of the amine exchange.

Objective: In the present study, the bioactive components present in the ethanol stem extract of Clausena anisata was analyzed by using Gas Chromatography Mass Spectrometry analysis technique (GC-MS). Clausena anisata, a medicinal plant belonging to the family Rutaceae, is represented by 20 species available in India and used traditionally for the treatment of several ailments but there is a requirement to identify its phytoconstituents, its target, mode of action and treatment using plant products either alone or in combination with synthetic drugs. Methods: Clausena anisata stem was procured from Manamettupatti, a village of Pudukottai District, Tamil Nadu. The shade dried stem was powdered and extracted using ethanol by maceration method. One microlitre of the extract was subjected to GC-MS analysis to detect the presence of bioactive compounds present in the stem of C. anisata. Results:The results showed that the ethanol stem extract of C. anisata contained nine bioactive compounds, of which the major one is n-hexadecanoic acid (78.54%), followed by 8-octadecenoic acid, methyl ester, [E]- (6.638%). The total number of compounds obtained was compared with National Institutes of Standard and Technology (NIST) library that contains more than 62,000 known compounds based on retention time and molecular mass. Conclusion: In this study, nearly nine compounds have been identified from the ethanolic stem extract of C. anisata using GC-MS analysis which was mainly composed of fatty acids and sterols. The GC-MS analysis is used to understand the nature of active principles present in this plant revealed that the plant can be used as a potential source of new useful drugs.

In the history of helicity, DNA is probably the prototypical helical structure. Besides this natural constituent of living cells, this review surveys helical structures based on organophosphorus derivatives. The first section contains phosphahelicenes constituted by a sequence of fused aromatic rings which can adopt a nonplanar screw-shaped topology. Helical structures can also arise from propeller-shaped molecules or by a succession of spirocycles illustrated consecutively. The last section reports systems where the helical arrangement comes from supramolecular organization. In this category fall acid. or metal organic frameworks and polymers. The synthesis and different applications, mainly in catalysis, are presented.
