Solid-phase extraction and validated spectrofluorimetric quantification of pamidronate in human plasma

Purpose: To design a simple and sensitive quantification procedure for pamidronate disodium (PAM) after its solid phase extraction from plasma. Methods: The procedure was based on derivatization of PAM using a suitable fluorogen, 4-chloro-7-nitro-2,1,3-benzoxazole. The product was determined spectrofluorometrically at excitation and emission wavelengths of 390 and 535 nm, respectively. The method was optimized for all factors that affect the reaction between PAM and the fluorogen. These factors include diluting solvent, pH of the reaction medium, volume of fluorogen solution, buffer pH, buffer volume, temperature and heating time. The method was fully validated according to US-FDA guidelines with respect to linearity, accuracy, precision, recovery, robustness and stability. Results: PAM was successfully extracted from human plasma with solid-phase extraction technique. A linear response was obtained in the concentration range of 10 – 100 ng/mL, with correlation coefficient of 0.998. Mean maximum plasma concentration of PAM was 9.73.2 +/- 3.2 mu mol/L, which was within the linear range of the proposed method, thereby confirming its sensitivity for the determination of plasma PAM. Conclusion: The proposed procedure is suitable for the quantification of PAM in human plasma after its solid phase extraction. The method is sensitive enough for use in PAM determination in pharmacokinetic studies. Moreover, it is likely a more cost-effective and simpler alternative method than high performance liquid chromatograph (HPLC) methods.

Synthesis and properties of benzoxazole-based liquid crystals containing ethynyl group

Series of heterocyclic compounds containing ethynyl group, 2-[4-[2-[4-(alkoxy)phenyl]ethynyl]phenyl] -benzoxazole derivatives (nPEPBx), are prepared and investigated. They display enantiotropic nematic and smectic mesophases with large mesophase ranges of 30-133 degrees C (heating) and 31-141 degrees C (cooling). Compared with reference analogues without ethynyl group, the compounds nPEPBx roughly give lower melting points and much higher nematic mesophase stability because of the introduction of triple carbon-carbon bond. Meanwhile, they show much higher birefringence (Delta n, 0.50-0.65 and 0.55-0.68 for experimental and calculated values with density functional theory (DFT), respectively) than common tolane-based liquid crystals, which indicates that the introduction of benzoxazole unit is an effective method to enhance Delta n values of the rod-like molecule. It is concluded that nPEPBx has a potential application in liquid crystal mixture as a dopant to enhance the performance of the host mixture.

New Fluorescent Nickel(II) Complexes as a Catalyst for Biodiesel Formation: Synthesis, Structure, Spectral Properties, and DFT Calculations

Two fluorescent heterocyclic ligands were obtained by reduction of imidazo[4,5-e][2,1]benzoxazole derivatives with Fe/HCl. New fluorescent nickel(II) complexes were synthesized by coordination of Ni(II) cation with the heterocyclic ligands. The structure of the complexes was established by spectral and analytical data, Job plot, and DFT calculations. Photophysical properties of Ni(II) complexes were characterized by UVVis and fluorescence spectroscopy. The optimized geometry, spectral properties, and energy difference between the HOMO and LUMO frontier orbitals of the ligands and Ni(II) complexes were obtained by DFT calculations at the B3LYP/6-311++G(d, p) level. The calculated spectral properties are in good agreement with the experimental values. The complexes were also tested as homogeneous catalysts for the transesterification of corn oil with methanol. The structure of the obtained product was confirmed by 1H NMR analysis. The catalytic results showed that the new Ni(II) complexes can be considered as potential candidates for the development of new catalytic systems for biodiesel production.

Facile Access to 1,4-Disubstituted Pyrrolo[1,2-a ]pyrazines from alpha-Aminoacetonitriles

An efficient and practical synthetic protocol for the synthesis of 1,4-disubstituted pyrrolo[1,2- a ]pyrazine derivatives is described that originates from alpha-substituted pyrroloacetonitriles which, in turn, are readily available from aryl and alkyl aldehydes. The alpha-pyrroloacetonitriles were subjected to a Friedel-Crafts acylation with methyl chlorooxoacetate followed by reduction of the nitrile group under Pd-catalyzed hydrogenation conditions and finally aromatization with DDQ leading to the desired pyrrolo[1,2- a ]pyrazine derivatives. This method was generalized and successfully applied to various aryl, heteroaryl, and alkyl substrates. The developed protocol provides direct and convenient access to 1,4-disubstituted ring systems in moderate to good overall yields (51-68%) without the need for purification of the intermediates. Further functionalization via the stepwise halogenation (bromination, iodination) and nitration was also demonstrated. In addition, the potential of the ester functionality for elaboration was demonstrated by manipulating into heterocyclic ring systems, exemplified by conversion into benzoxazole derivatives.

Liver fructose-1,6-bisphosphatase (FBPase) is a key enzyme in the gluconeogenesis pathway. Inhibiting FBPase activity represents a potential treatment for type 2 diabetes mellitus. A series of novel N-arylsulfonyl-4-arylamino-indole-2-carboxamide derivatives have been disclosed as FBPase inhibitors. Through extensive structure-activity relationship investigations, a promising candidate molecule Cpd118 [sodium (7-chloro-4-((3-methoxyphenyl)amino)-1-methyl-1H-indole-2-carbonyl] [(4-methoxyphenyl)sulfonyl)amide] has been identified with high inhibitory activity against human liver FBPase (IC50, 0.029 +/- 0.006 mu M) and high selectivity relative to the other six AMP-binding enzymes. Importantly, Cpd118 produced significant glucose-lowering effects on both type 2 diabetic KKAy mice and ZDF rats as demonstrated by substantial reductions in the fasting and postprandial blood glucose levels, as well as the HbA1c level. Furthermore, Cpd118 elicited a favorable pharmacokinetic profile with an oral bioavailability of 99.1%. Moreover, the X-ray crystal structure of the Cpd118-FBPase complex was resolved, which revealed a unique binding mode and provided a structural basis for its high potency and selectivity.

Recent endeavors on design, synthesis, fluorescence mechanisms and applications of benzazole-based molecular probes toward miscellaneous species

Owing to their much more accessible structural diversity and recognition mechanism, the fluorescent probes with small molecular scaffold are significant, and they have been broadly investigated in the cutting edge of materials and biological chemistry. Known as the facile synthesis, expedient structural modification, good molecular stability, admirable fluorescence properties, multiple binding sites and excellent environmental compatibility, the benzazole moieties are under growing attraction in fluorescent probes for efficient detection of different species, such as cations (H+, Al3+, Hg2+, Cu2+, etc.), anions (HSO3-, F-, OH-, CN- , etc.), biomolecules (thiols, amino acids, etc.) and explosives (picric acid and TNT, etc.). In this review, benzimidazole-, benzoxazole- and benzothiazole-based fluorescent probes that have been reported in the recent three years (2017-2019) are refined to elucidate the progress of benzazole-based probes by combining their design strategy, synthetic route, sensing mechanism and applications. We wish that it may afford valuable recommendation to the construction of intelligent and versatile fluorescent probes based on benzazole derivatives.
