Cancer is a leading cause of human mortality around the globe. In this study, mechanism-based SAR (Structure Activity Relationship) was employed to investigate the carcinogenicity of aromatic amines and nitroaromatics based on CPDB. Principal component analysis and cluster analysis were used to construct the SAR model. Principle component analysis generated three principal components from 12 mechanism-based descriptors. The extracted principal components were later used for cluster analysis, which divided the selected 55 chemicals into six clusters. The three principal components were proposed to describe the transport, reactivity and electrophilicity properties of the chemicals. Cluster analysis indicated that the relevant transport properties positively correlated with the carcinogenic potential and were contributing factors in determining the cardnogenicity of the studied chemicals. The mechanism-based SAR analysis suggested the electron donating groups, electron withdrawing groups and planarity are significant factors in determining the carcinogenic potency for studied aromatic compounds. The present study may provide insights into the relationship between the three proposed properties and the carcinogenesis of aromatic amines and nitroaromatics.

FLT3 mutation is among the most common genetic mutations in acute myeloid leukemia (AML), which is also related with poor overall survival and refractory in AML patients. Recently, FLT3 inhibitors have been approved for AML therapy. Herein, a series of new compounds with pyrazole amine scaffold was discovered, which showed potent inhibitory activity against FLT3-ITD and significant selectivity against both FLT3-ITD and AML cells expressing FLT3-ITD. Compound 46, possessing the most promising cellular activity, blocked the autophosphorylation of FLT3 pathway in MV4-11 cell line. Furthermore, the apoptosis and downregulation of P-STAT5 were also observed in tumor cells extracted from the MV411 cell xenografts model upon compound 46 treatment. Compound 46 was also metabolically stable in vitro and suppressed tumor growth significantly in MV4-11 xenografts model in vivo. Compound 46 showed no toxicity to the viscera of mice and caused no decrease in body weight of mice. In conclusion, the results of this study could provide valuable insights into discovery of new FLT3 inhibitors, and compound 46 was worthy of further development as potential drug candidate to treat AML (C) 2019 Elsevier Masson SAS.

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

Design of chemically novel, biologically potent small heterocyclic molecules with anticancer activities, which targets the enzyme heparanase has gained prominent clinical interest. We have synthesized a novel class of carboxamide derivatives by coupling various substituted aromatic acid hydrazides and triazoleamine with pyrrolidine carboxylic acid by using coupling agents. The synthesized compounds are characterized by spectroscopic techniques such as FT-IR, DIMS and NMR. These compounds arc investigated for cytotoxicity on different cancer cell lines and heparanase inhibitory activity. Most of them showed moderate heparanase inhibitory activity and good cytotoxicity.

A covalent hybrid of halloysite-poly(methyl methacrylate-co-maleic anhydride) was prepared and applied for the immobilization of Pd nanoparticles. The hybrid system, Pd@Hal-Gua-Poly, was then characterized via TEM, TGA, ICP, BET, FTIR and XRD and successfully used as a heterogeneous catalyst for promoting two main Pd-catalyzed reactions, i.e. hydrogenation of nitro-arenes and Suzuki coupling reaction under mild and eco-friendly conditions. The study of recyclability of the catalyst confirmed high recyclability and low Pd leaching of Pd@Hal-Gua-Poly. Moreover, the hot-filtration test showed the heterogeneous nature of the catalysts. Notably, the comparison of the activity of the catalyst with that of Pd@Hal and Pd@Poly confirmed the superior catalytic activity of the former, indicating that the hybridization of Hal and Poly could lead to the improvement of the catalytic activity.

N-Acylpyrrole-type amides are a class of versatile building blocks in asymmetric synthesis. We report that by employing Ni(COD)(2)/2,2 ‘-bipyridine (5 mol%) catalytic system, the direct, catalytic alcoholysis of N-acylpyrrole-type aromatic and aliphatic amides with both primary and secondary alcohols can be achieved efficiently under very mild conditions (rt, 1 h) even at gram scale. By increasing the catalyst loading to 10 mol%, prolonging reaction time (18 h), and/or elevating reaction temperature to 50 degrees C/80 degrees C, the reaction could be extended to both complex and hindered N-acylpyrroles as well as to N-acylpyrazoles, Nacylindoles, and to other (functionalized) primary and secondary alcohols. In all cases, only 1.5 equiv. of alcohol were used. The value of the method has been demonstrated by the racemization-free, catalytic alcoholysis of chiral amides yielded from other asymmetric methodologies.

We report here the stereoselective bioreduction of -nitro ketones catalyzed by ketoreductases (KREDs) with publicly known sequences. YGL039w and RasADH/SyADH were able to reduce 23 class I substrates (1-aryl-2-nitro-1-ethanone (1)) and ten class II substrates (1-aryloxy-3-nitro-2-propanone (4)) to furnish both enantiomers of the corresponding -nitro alcohols, with good-to-excellent conversions (up to >99%) and enantioselectivities (up to >99% ee) being achieved in most cases. To the best of our knowledge, KRED-mediated reduction of class II -nitro ketones (1-aryloxy-3-nitro-2-propanone (4)) is unprecedented. Select -nitro alcohols, including the synthetic intermediates of bioactive molecules (R)-tembamide, (S)-tembamide, (S)-moprolol, (S)-toliprolol and (S)-propanolol, were stereoselectively synthesized in preparative scale with 42% to 90% isolated yields, showcasing the practical potential of our developed system in organic synthesis. Finally, the advantage of using KREDs with known sequence was demonstrated by whole-cell catalysis, in which -nitro alcohol (R)-2k, the key synthetic intermediate of hypoglycemic natural product (R)-tembamide, was produced in a space-time yield of 178 g L-1 d(-1) as well as 95% ee by employing the whole cells of a recombinant E. coli strain coexpressing RasADH and glucose dehydrogenase as the biocatalyst.

Lignin is a biodegradable, abundant and renewable natural polymer on earth. In this study, deep eutectic solvents (DESs)-modified lignin heterogeneous catalysts were prepared for the first time via a facile acid-base interaction between choline chloride (ChCl) and p-aminobenzoic acid (PABA) or its derivatives, which were used to efficiently catalyze the cycloaddition of CO2 and terminal epoxides under green and mild conditions. Among them, lignin-ChCl-PABA was found to exhibit the highest catalytic activity for the cycloaddition of epoxides in the presence of 1.0 MPa of CO2 while retaining high selectivity, which far outperformed those achieved on the homogeneous EDSs catalytic system. A series of cyclic carbonates could be obtained in high yields (90-99%), and lignin-ChCl-PABA was stable and reusable for the cycloaddition reaction (84% yield after 5 recycles). The attaching DES of ChCl/PABA onto the functional lignin increased the catalytic activity and also made the catalyst easier to recycle from the reaction mixture. The -OH and -NH2 groups on the surface of lignin-ChCl-PABA played a very important role in the acceleration of the cycloaddition reaction under solvent free conditions.
