Translational impact of novel widely pharmacological characterized mofezolac-derived COX-1 inhibitors combined with bortezomib on human multiple myeloma cell lines viability

A set of novel diarylisoxazoles has been projected using mofezolac (1) as a lead compound to investigate structure-inhibitory activity relationships of new compounds and the cyclooxygenases (COXs) catalytic activity. Mofezolac was chosen because is the most potent and selective reversible COX-1 inhibitor [COX-1 IC50 = 0.0079 muM and COX-2 IC50 > 50 muM, with a selectivity index (SI) in favor of COX-1 higher than 6300]. Seventeen new compounds were synthesized in fair to good yields and evaluated for their COXs inhibitory activity and selectivity. SIs ranged between 1 and higher than 1190.3,4-Bis(4-methoxyphenyl)-5-vinylisoxazole (22) has the highest SI with COX-1 IC50 = 0.042 muM and COX-2 IC50 > 50 muM. 1 and 22 were superior to aspirin in inhibiting platelet aggregation (IC50 = 0.45, 0.63 and 1.11 muM, respectively) in human platelet rich plasma (hPRP) assay. They did not induce blood coagulation and hemolysis, and are neither genotoxic nor mutagen. 1 and 22 slightly increase bortezomib cytotoxic effect on multiple myeloma (MM) cell lines (NCI-H929 and RPMI-8226) and affects MM cell cycle and apoptosis when co-administered with the proteasome inhibitor bortezomib, a drug clinically used to treat plasma cell neoplasms including MM. In addition, structure-based binding mode of 1 and 22, through Fingerprints for Ligands and Proteins (FLAG) calculation, allowed to explain the one order of magnitude difference between COX-1 IC50 values of the two compounds. Specifically, the higher inhibitory potency seems due to the formation of a H-bond between COX-1 S530 and the carboxyl, present in 1 and absent in 22.

Ligand-free-palladium-catalyzed direct 4-arylation of isoxazoles using aryl bromides

4-rylisoxazoles can be easily prepared by a palladium-catalysed C-H bond activation/arylation of 3,5-disubstituted isoxazoles using aryl or heteroaryl bromides. Good yields were generally obtained by using 0.1-0.5 mol-% of the airstable PdCl2 complex as the catalyst. A range of functional groups such as acetyl, formyl, ester, fluoro, nitro, trifluoro-methyl or nitrile on the aryl bromide is tolerated. This reaction is environmentally attractive, as the major waste is KBr/ AcOH instead of the metallic salts arising from classical cross-coupling procedures,

Electrochemical mineralization of sulfamethoxazole by Ti/SnO 2-Sb/Ce-PbO2 anode: Kinetics, reaction pathways, and energy cost evolution

Electrochemical mineralization of sulfamethoxazole (SMX) was performed in an undivided cell equipped with a Ti/SnO2-Sb/Ce-PbO2 anode and a Ti cathode. The reactions kinetics was determined as a function of applied current density (0.5-40 mA cm-2), initial SMX concentration (10-400 mg L-1), initial pH (3-11), and electrode distance (3-20 mm). Degradation of SMX in contaminated lake water was quicker than that in deionized water. The electrochemical degradation of SMX followed pseudo-first-order kinetics. The nearly complete mineralization of SMX (>95%) was achieved in 60 min as the current density was higher than 10 mA cm -2. The major mineralization products in aqueous solution were NH4+ and SO42-. The aromatic intermediates including 3-amino-5-methylisoxazole (AMI), p-benzoquinone (BZQ), and sulfanilic acid (SFN) were analyzed and quantified. A possible electrochemical mineralization mechanism of SMX was proposed. Firstly, the sulfone group or isoxazole aromatic ring was attacked by hydroxyl radical (OH), followed by the formation of sub-structures analogues such as SFN and AMI. Subsequently, the OH attacked the different groups of the sub-structures analogues to release NH4+ and SO42-. Furthermore, successive hydroxylation of the formed aromatic intermediates including BZQ and 3, 4, 5-trihydroxy-5-methylisoxazole occurred. The mineralization of intermediates to CO2 and H2O was finally achieved. The nitrogen atom of the isoxazole molecule was converted into NO3-, which was then reduced to gas at the cathode. The economic feasibility was evaluated by determining the energy cost. The results showed that the residence time and energy cost of SMX degradation at the optimal conditions from 100 mg L-1 to 1 mg L-1 were 32.9-23.0 min and 26.3-46.3 Wh L-1, respectively. This electrochemical technique is expected to be an interesting alternative for the treatment of SMX in wastewater.

1,4-Diazabicyclo[2.2.2]octane (DABCO) as an efficient reagent for the synthesis of isoxazole derivatives from primary nitro compounds and dipolarophiles: The role of the base

The dehydration of primary nitro compounds can be performed by bases in the presence of dipolarophiles. The reactivity of several tertiary amines or azaheteroaromatic compounds containing one or two basic centres is shown to be related to the ability of the protonated base to establish H-bonded ion pairs with the adduct that is formed from the nitronate and the dipolarophile in chloroform. Among the organic bases examined, caged tertiary diamine 1,4-diazabicyclo[2.2.2]octane (DABCO) gave the best results. The reaction is applicable to activated nitro compounds and to phenylnitromethane and affords isoxazoline derivatives in higher yields compared with those of other methods. The reaction, however, is not compatible with nitroalkanes. The proposed mechanism of the reaction is based on the collapse of the H-bonded ion pair. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
