Pruinosanones A-C, anti-inflammatory isoflavone derivatives from Caragana pruinosa

Pruinosanone A (1), a novel spirochromone, was isolated from the roots of Caragana pruinosa. Two biogenetically related isoflavone intermediates, pruinosanones B and C (2 and 3), were also isolated, together with five known analogs identified as 3-hydroxy-9-methoxypterocarpan (4), 7,2′-dihydroxy-4′-methoxyisoflavanol (5), retusin-8-methylether (6), 7,2′-dihydroxy-8,4′-dimethoxy isoflavone (7) and 7,3′-dihydroxy-8,4′-dimethoxy isoflavone (8). The structures of 1-3 were elucidated based on extensive spectroscopic methods. Notably, 1 is the first example of a spirochromone possessing an unprecedented pentacyclic skeleton containing a spiro[benzo[d][1,3] dioxole-2,3′-chroman]-4′-one motif, which was confirmed by X-ray diffraction analysis. A plausible biosynthetic pathway for 1 was also proposed. Compounds 1-8 were tested for their ability to inhibit nitric oxide (NO) production in LPS-induced RAW 264.7 macrophages, and compounds 1-3 were the most potent inhibitors of NO production, with IC50 values of 1.96, 1.93 and 1.58 mu M, respectively. A structure-activity relationship analysis revealed that the fused 2-isopropenyl-2,3-dihydrofuran moiety plays a vital role in the potency of these compounds. Moreover, 1 was found to significantly inhibit inducible nitric oxide synthase (iNOS) protein expression, which accounts for the potent inhibition of NO production by this spirochromone.

A unique rhodamine-based ‘off-on’ molecular spy for selective detection of trivalent aluminum and chromium ions: Synthesis, crystal structure and spectroscopic properties along with living cell imaging

The well known rhodamine framework offers an ideal model for the development of fluorescence enhanced chemosensors. Herein, a novel and simple molecule chemosensor, (E)-2-((benzo[d][1,3] dioxol-4-ylmethylene)amino)-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one (L), has been designed by combining a rhodamine B hydrazide and a benzo[d][1,3]dioxole-4-carbaldehyde in a single molecule to prove the selectivity and sensitivity for Al3+ and Cr3+ in a dual-channel mode (fluorescence emission and UV-Vis). The signal transduction occurred by the increase of conjugation in the ring-open form than in the ring-closed form. Furthermore, the chemosensor L could also be used as an imaging probe without cytotoxicity for uptake and detection of Al3+ ion in HeLa cells. (C) 2014 Elsevier B.V. All rights reserved.

Synthesis and cytotoxicity studies of new dimethylamino-functionalised and aryl-substituted titanocene anti-cancer agents

From the carbolithiation of 6-N,N-dimethylamino fulvene (3a) and different lithiated aryl species [p-N,N-dimethylanilinyl lithium, p-anisyl lithium and 4-lithio-benzo[1.3]dioxole (2a-c)], the corresponding lithium cyclopentadienide intermediates 4a-c were formed. These three lithiated intermediates underwent a transmetallation reaction with TiCl4 resulting in dimethylamino-functionalised and aryl-substituted titanocenes 5a-c. When these titanocenes were tested against LLC-PK cells, the IC50 values obtained were of 54, 45 and 26 mu M for titanocenes 5a, b and c, respectively. The most cytotoxic titanocene in this paper, 5c is approximately 10 times less cytotoxic than cis-platin, which showed an IC50 value of 3.3 mu M, when tested on the LLC-PK cell line, but approximately 100 times better than titanocene dichloride.

Electrochemical Behavior and Antioxidant Activity of Hibalactone

Hydrocotyle umbellata L. is a groundcover plant that has been used in the folk medicine of Argentina, Brazil, Cuba e India, mainly to reduce inflammatory processes. The lignan, hibalactone, can be isolated from the roots of the plant. In the anti-inflammatory and antioxidant activity of such natural products, it is believed that the mechanism of action involves the butyrolactone ring, which would act as free pharmacophore. In this study, electrochemical, spectrometric and computational chemistry approaches were used to evaluate the lignan antioxidant activity and electro-oxidation pathway. Electrochemical measurements were performed in a 3 mL cell, operated in a three electrode system, consisting in an Ag/AgCl reference electrode, platinum as counter electrode and glassy carbon electrode was used as working electrode. Radical scavenging assays were performed with DPPH and ABTS. In the computational chemistry approach geometry, optimization was performed with semi empirical calculations (PM3) and the orbitals/charges calculations were performed by the extended Huckel method. The voltammetry showed a very slight variation with pH alteration, which can be justified by lactone hydrolysis that occurs in acidic and basic pH. In the HOMO and total charge density distribution it was possible to observe that the higher prevalence was in the benzo[1,3]dioxole rings and in the alkenes/alkanes in proximity with the lactone ring. The hibalactone displayed a single quasi-reversible electro-oxidation. Given the HOMO and charge density distribution in the lignan, more so the single oxidation in the evaluated potential, it is reasonable to infer that the alkene bonded with the lactone ring was a probable site of oxidation.

UV-resistant amorphous fluorinated coating for anodized titanium surfaces

In this work, a high molecular weight copolymer of tetrafluoroethylene and perfluoro-4-trifluoromethoxy-1,3-dioxole (HYFLON (R) AD60) and two perfluoropolyethers (PFPEs) containing ammonium phosphate or triethoxysilane functionalities, FLUOROLINK (R) F10 and FLUOROLINK (R) S10 respectively, have been evaluated as protective coatings that can be easily applied on anodized titanium surfaces. Water and n-dodecane contact angle measurements have been recorded by using the sessile drop method for bare and coated surfaces in order to determine the hydrophobic and oleophobic properties of the coatings. The UV-stability of coatings have been studied by Fourier transform infrared spectroscopy (FT-IR) analyses and by observing the variation of water contact angles on coated substrates before and after UV irradiation at regular time intervals. The thickness of the fluorinated films has been measured by ellipsometry and by weight evaluation. Preliminary tests of the adhesion between films and substrate have been conducted.
