Design, synthesis, and evaluation of novel heteroaromatic analogs of curcumin as anti-cancer agents

To improve the potential of curcumin to treat advanced hormone-refractory prostate cancer, three series (A-C) of heteroaromatic analogs (thirty two compounds) with different monoketone linkers have been synthesized and evaluated for cytotoxicity against two human androgen-independent prostate cancer cell lines (PC-3 and DU-145). Among them, thirty analogs are more potent than curcumin against PC-3 cells, and twenty one analogs are more cytotoxic towards DU-145 cells relative to curcumin. The most potent compounds (44, 45, 51, and 52) also showed impressive cytotoxicity against three other metastatic cancer cell lines (MDA-MB-231, HeLa, and A549), with IC50 values ranging from 50 nM to 390 nM. All four most potent analogs exhibited no apparent cytotoxicity towards the MCF-10A normal mammary epithelial cells. Taken together, selective enhancement of cell death in prostate cancer cell lines and other aggressive cancer cell lines suggests that nitrogen-containing heteroaromatic rings are promising bioisosteres of the substituted phenyl ring in curcumin.

3 Peptide Deformylase Inhibitors

The successful development of numerous antibiotics in the 1930s-1960s [1] created the complacent feeling in the medical and scientific communities that bacterial infections had been defeated, resulting in a decrease in academic and industrial research in the antimicrobial area. Unfortunately, bacteria adapted to their hostile new environment by developing or acquiring resistance mechanisms that eventually rendered many of these antibiotics ineffective. Currently, infectious diseases are still a leading cause of death in the world [2], while the approval of new antibacterial agents has been steadily decreasing over the last 20 years [3]. Although the development of second- and third-generation antibiotics from existing classes has improved their activity and safety, bacterial resistance to these drugs continues to increase. In order to directly address this issue, antimicrobial agents with novel mechanisms of action are needed. However, of the 11 new antibiotics approved by the Food and Drug Administration (FDA) in the last 7 years, only two act through a novel mechanism: linezolid, an oxazolidinone, and daptomycin, a cyclic lipopeptide, both of which have been approved for the treatment of Gram-positive bacterial infections only. While considerable effort is underway to develop next generation oxazolidinones covering a broader spectrum of community and hospital infections [4-6], the identification of new drugs that target previously untapped bacterial pathways will play a critical role in the development of antibiotics active against resistant pathogens. This article summarises the general characteristics of a novel antibacterial target, peptide deformylase (PDF) and reviews the design, structure-activity relationships (SAR) and properties of known PDF inhibitors, including pre-clinical and clinical data for the most advanced members of this class.

Comparative study on sulfamethoxazole degradation by Fenton and Fe(II)-activated persulfate process

Pharmaceuticals and personal care products (PPCPs) are emerging contaminants, which are ubiquitous and pose the potential risk to ecosystem and human health. It is necessary to remove PPCPs from water and wastewater. In this study, sulfamethoxazole, a widely used antibiotic, was chosen as targeted pollutant. Fenton process and persulfate process were employed to remove sulfamethoxazole from aqueous solution. The results showed that Fenton process required less amount of Fe(ii) and oxidant than persulfate process to achieve 100% removal of sulfamethoxazole in the water sample prepared with de-ionized water. The maximal mineralization reached 83% when hydrogen peroxide concentration was 1 mM and Fe(ii) was 0.05 mM for Fenton process. The maximal mineralization for persulfate process was 60% with 4 mM of persulfate and 4 mM of Fe(ii). The increase of Fe(ii) concentration could increase the decomposition of hydrogen peroxide and persulfate, but did not increase the mineralization of sulfamethoxazole, indicating that the decomposition of hydrogen peroxide and persulfate was not positive correlation with the removal and mineralization of sulfamethoxazole. Five intermediate compounds were detected in Fenton process while eight intermediate compounds in persulfate process, suggesting that different degradation pathway occurred in the two processes. The wastewater components had negative effect on the degradation of sulfamethoxazole for both Fenton and persulfate processes. The removal efficiency of sulfamethoxazole was 52.5% and 52.3%, respectively, for Fenton and persulfate processes. Persulfate process could be an alternative for treating the real wastewater containing PPCPs.

The method employs cyclic hypervalent iodine as oxidant and features good functional-group tolerance. Another advantage of this reaction is that sequential C-H/C-H and C-H/N-H coupling could be achieved. This journal is

Photo-Fenton degradation of a herbicide (2,4-D) in groundwater for conditions of natural pH and presence of inorganic anions

The effects of four inorganic anions (Cl?, SO42?, HCO3?, NO3?) usually present in groundwater were investigated on the photo-Fenton degradation of 2,4-dichlorophenoxyacetic acid (2,4-D). A kinetic model derived from a reaction sequence is proposed using the ferrioxalate complex as iron source at pH close to natural conditions (pH = 5). It was demonstrated that oxalate not only maintained iron in solution for the natural groundwater system, but also increased the photochemical activation of the process. Results showed that the minimum conversion of 2,4-D for the simulated groundwater after 180 min was 63.80%. This value was only 14.1% lower than the conversion achieved without anions. However, with all anions together, the consumption of hydrogen peroxide (HP) per mole of herbicide showed an increase with respect to the test without anions. Only one kinetic parameter was estimated for each anion applying a nonlinear regression method. Subsequently, these optimized kinetic constants were used to simulate the system behaviour, considering the influence of all the studied anions together. A good agreement between kinetic model predictions and experimental data was observed, with the following errors: RMSE2,4-D = 3.98 ¡Á 10?3 mM, RMSEHP = 1.83 ¡Á 10?1 mM, RMSEOX = 1.39 ¡Á 10?2 mM, and RMSE2,4-DCP = 5.59 ¡Á 10?3 mM.
