Biased multicomponent reactions to develop novel bromodomain inhibitors

BET bromodomain inhibition has contributed new insights into gene regulation and emerged as a promising therapeutic strategy in cancer. Structural analogy of early methyl-triazolo BET inhibitors has prompted a need for structurally dissimilar ligands as probes of bromodomain function. Using fluorous-tagged multicomponent reactions, we developed a focused chemical library of bromodomain inhibitors around a 3,5-dimethylisoxazole biasing element with micromolar biochemical IC50. Iterative synthesis and biochemical assessment allowed optimization of novel BET bromodomain inhibitors based on an imidazo[1,2-a]pyrazine scaffold. Lead compound 32 (UMB-32) binds BRD4 with a Kd of 550 nM and 724 nM cellular potency in BRD4-dependent lines. Additionally, compound 32 shows potency against TAF1, a bromodomain-containing transcription factor previously unapproached by discovery chemistry. Compound 32 was cocrystallized with BRD4, yielding a 1.56 A resolution crystal structure. This research showcases new applications of fluorous and multicomponent chemical synthesis for the development of novel epigenetic inhibitors.

Effective treatment of residue of acrylic acid production using a fluid-bed/fixed-bed system with low energy consumption

In order to effectively deal with large amounts of complex organic pollutants in the harmful distillation residues with low energy consumption, a novel two-stage fluid-bed/fixed-bed system was designed to catalyze oxidation of acrylic acid production residue. The effects of fluid-bed temperature, gaseous hourly space velocity (GHSV), and oxygen excess rate on the purification of acrylic acid production residue in the two-stage fluid-bed/fixed-bed system were studied to prove the feasibility of the method. The chemical oxygen demand (COD) of the discharged liquid was <100?mg/L, and the volatile organic compounds (VOCs) of the discharged gas amounted to <10?mg/m3 with a fluid-bed temperature of 380C, emulsified residue's GHSV of 0.28?L/(kgcat¡¤hr), and O2 excessive rate of more than 4.32. The result of techno-economics indicates the feasibility of the long-term operation of process. Results further illustrate the advantages of the proposed two-stage fluid-bed/fixed-bed system, which can treat acrylic acid production residue with high efficiency (COD?Tetrahydrofuran – Wikipedia,

QUANTITATIVE RELATIONS BETWEEN STRUCTURE AND ANTIINFLAMMATORY ACTIVITY OF ARYLOXOALKANOIC ACIDS

The antiinflammatory effect of a series of aryloxoalkanoic acids II and of their biphenyl derivatives III was examined by measuring the inhibition of the development of carageenan- and adjuvant-induced edemas.The quantitative relations between the antiinflammatory effect and physicochemical and structural parameters of the compounds tested were evaluated.The equations obtained by the method of regression analysis showed a significant linear dependence of both inhibitory activities on the lipophilicity of the compounds and a considerable effect of some structural changes as expressed by indicator variables.The antiinflammatory effect is especially enhanced in both tests by the presence of a cyclic substituent at the aromatic ring.The high antiinflammatory effect of biphenylyl derivatives III is paralleled by their prolonged action.The prolongation of the effect is most likely a result of a suitable biotransformation of acid III to an efficient metabolite.The structural requirements which resulted from both the regression analysis and from the hypothesis of biotransformation of acids III were utilized in the synthesis of suitably substituted biphenylyloxoalkanoic acids.By this approach derivatives IIIe-i were obtained some of which showed a high antiinflammatory and also protracted effect. 4-(2′,4′-Difluorobiphenylyl)-4-oxo-2-methylbutanoic acid (VUFB 16066, Flobufen) was chosen for further preclinical development.

Switchable synthesis of 2,5-dimethylfuran and 2,5-dihydroxymethyltetrahydrofuran from 5-hydroxymethylfurfural over Raney Ni catalyst

Raney-type metals (Cu, Co and Ni) were employed to catalyze hydrogenation of 5-hydroxymethylfurfural. Switchable synthesis of 2,5-dimethylfuran and 2,5-dihydroxymethyltetrahydrofuran was achieved with 96% and 88.5% yield respectively over Raney Ni, demonstrating high feasibility for industrialization. The excellent yields can be explained by the fact that Raney Ni facilitates the hydrogenation reaction but has limited deoxygenation ability at low temperature, while high temperature promotes the deoxygenation step. The reaction pathway was analyzed by time course experiments and HMF hydrogenation over model catalysts was performed. The reaction mechanism related to the respective catalytic sites was discussed and proposed, which has great implications in the design of efficient and non-noble metal catalysts.
