Simultaneous determination of multi-class pesticide metabolites in fish (Siluriformes: Ariidae): protocol developed for human dietary risk in Ceara coast, Brazil

An analytical protocol for the determination of multi-class pesticide metabolites chlorpyrifos-methyl (Chlorp-M), S-metolachlor (S-Metola), malaoxon (malaox), 2-chloro-4,6-diamino-1,3,5-triazine (2-CAAT), carbofuran phenol (CarbPhenol), 3-phenoxybenzoic acid (3-PBA) and one polycyclic aromatic hydrocarbon metabolite 1-hydroxypyrene (1-OHP) in fish was developed using the analytical technique GC?MS. Besides the verification of metabolite occurrence in catfish from both metropolitan region and intensive farming region, the protocol was applied to evaluate human health risk due to the contaminated fish consumption in Brazilian tropical semiarid coast, for the first time. Following the national and international quality standards, the analytical protocol showed acceptable recoveries with good repeatability. Limit of detection (LD) and limit of quantification (LQ) values ranged from 0.15?mug L?1 to 36.0?mug L?1 and from 0.55?mug L?1 to 112.9?mug L?1, respectively, and the sensitivity was considered satisfactory since it is a complex matrix. Only tree pesticide metabolites were detected in the captured catfish. CarbPhenol and 3-PBA presence may be attributed to the application in rural and urban activities for pest control, public health campaigns and household, while malaox presence may be due to the dengue control program. Malaox contents were significantly higher than 3-PBA and CarbPhenol for the three estuaries of the Ceara coast, but the dietary risk due to the consumption of these fish, mainly for the coastal communities, based on the values established for their parental compounds, was considered low for both 3-PBA and malaox, and of probable high risk for CarbPhenol. Results represent an alert to the high possibility of risks to human health due to the overuse of pesticides in Brazil, mainly carbofuran pesticide.

Chemical inactivation of the E3 ubiquitin ligase cereblon by pomalidomidebased homo-PROTACs

The immunomodulatory drugs (IMiDs) thalidomide and its analogs, lenalidomide and pomalidomide, all FDA approved drugs for the treatment of multiple myeloma, induce ubiquitination and degradation of the lymphoid transcription factors Ikaros (IKZF1) and Aiolos (IKZF3) via the cereblon (CRBN) E3 ubiquitin ligase for proteasomal degradation. IMiDs have recently been utilized for the generation of bifunctional proteolysis targeting chimeras (PROTACs) to target other proteins for ubiquitination and proteasomal degradation by the CRBN E3 ligase. We designed and synthesized pomalidomide-based homobifunctional PROTACs and analyzed their ability to induce self-directed ubiquitination and degradation of CRBN. Here, CRBN serves as both, the E3 ubiquitin ligase and the target at the same time. The homo-PROTAC compound 8 degrades CRBN with a high potency with only minimal remaining effects on IKZF1 and IKZF3. CRBN inactivation by compound 8 had no effect on cell viability and proliferation of different multiple myeloma cell lines. This homo-PROTAC abrogates the effects of IMiDs in multiple myeloma cells. Therefore, our homodimeric pomalidomide-based compounds may help to identify CRBN?s endogenous substrates and physiological functions and investigate the molecular mechanism of IMiDs.

Low-Pressure Cobalt-Catalyzed Enantioselective Hydrovinylation of Vinylarenes

An efficient and practical protocol for the enantioselective cobalt-catalyzed hydrovinylation of vinylarenes with ethylene at low (1.2 bar) pressure has been developed. As precatalysts, stable [L2CoCl2] complexes are employed that are activated in situ with Et2AlCl. A modular chiral TADDOL-derived phosphine-phosphite ligand was identified that allows the conversion of a broad spectrum of substrates, including heterocyclic vinylarenes and vinylferrocene, to smoothly afford the branched products with up to 99 % ee and virtually complete regioselectivity. Even polar functional groups, such as OH, NH2, CN, and CO2R, are tolerated.

Synthesis of chiral 3-substituted phthalides by a sequential organocatalytic enantioselective aldol-lactonization reaction. Three-step synthesis of (S)-(-)-3-butylphthalide

(Chemical Equation Presented) The development of efficient methods for the facile construction of important molecular frameworks is an important goal in organic synthesis. Chiral 3-substituted phthalides are widely distributed in a large collection of natural products with broad, potent, and potentially path-pointing biological activities. In this investigation, we have uncovered an unprecedented organocatalytic asymmetric aldol-lactonization reaction of 2-formylbenzoic esters with ketones/aldehydes for convenient construction of the enantioenriched “privileged” scaffold. As a result of the sensitive nature of substrate structures of an organocatalytic enantioselective aldol reaction, after extensive optimization of reaction conditions, catalyst L-prolinamide alcohol IV is identified as the best promoter. Interestingly, it is found that in this reaction, addition of an acid additive PhCO2H can significantly enhance reaction efficiency with use of only as low as 2.5 mol % IV for the process. Moreover, due to the sensitivity of reaction conditions toward a sequential aldol-lactonization process without affecting enantioselectivity and racemization, it is essential to remove the catalyst for the subsequent facile lactonization reaction in the presence of K 2CO3. The aldol-lactonization processes serve as a powerful approach to the preparation of synthetically and biologically important 3-substitued phthalides with a high level of enantioselectivities. A 3-step catalytic asymmetric synthesis of the natural product of 3-butylphthalide is reported.
