The Meerwein-Ponndorf-Verley (MPV) reaction is an attractive approach to selectively reduce carbonyl groups, and the design of advanced catalysts is the key for these kinds of interesting reactions. Herein, we fabricated a novel zirconium organoborate using 1,4-benzenediboronic acid (BDB) as the precursor for MPV reduction. The prepared Zr-BDB had excellent catalytic performance for the MPV reduction of various biomass-derived carbonyl compounds (i.e., levulinate esters, aldehydes and ketones). More importantly, the number of borate groups on the ligands significantly affected the catalytic activity of the Zr-organic ligand hybrids, owing to the activation role of borate groups on hydroxyl groups in the hydrogen source. Detailed investigations revealed that the excellent performance of Zr-BDB was contributed by the synergetic effect of Zr4+ and borate. Notably, this is the first work to enhance the activity of Zr-based catalysts in MPV reactions using borate groups.

A decarboxylative protocol has been developed toward a range of carbocycles. The key success is based on the use of a batch of newly designed cyclic carbonates as substrates that can provide carbon-carbon zwitterion intermediate under palladium catalysis. The kinetics of the reactions are controllable toward either strained seven- or thermodynamically more favored five-membered carbocycles. The release of this chemistry will shed light on the synthesis of complex and valuable cyclic structures.

A heterogeneous organic-inorganic hybrid durable nanocatalyst gamma-Al2O3@Silane-TMG was prepared by covalently functionalization of nano-gamma-Al2O3 through anchored 3-chloropropyl- trimethoxysilane with 1,1,3,3-tetramethylguanidine (TMG). The structure of the catalyst was characterized by various techniques including FT-IR, XRD, SEM, EDX and TGA analyses. The synthesized nanocatalyst was successfully used in an efficient and green four-component synthesis of pyrazolopyranopyrimidine derivatives using ethyl acetoacetate, hydrazine hydrate, arylaldehydes and barbituric acid (or thiobarbituric acid) in H2O at 40 oC. This practical method produced the desired products at reduced reaction times (10-25 min) and high to excellent yields (85-98%). The main advantages of this practical method are the use of heterogeneous basic nanocatalyst, simple work-up procedure with no need to chromatographic purification, affording highly selective conversion and recyclability of the catalyst which could be used in 5 cycles with only a small decrease in its activity.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Prenylated chalcones xanthohumol (1) and 2 ‘-hydroxy-3,4,4 ‘-trimethoxy-6 ‘-O-prenyl chalcone (2) were synthesized through the Claisen-Schmidt condensation, O-prenylation, and Claisen rearrangement and deprotection respectively, using phloroglucinol and appropriate benzaldehydes as starting materials. Based on the Mannich reaction of prenylated chalcone 1 or 2 with various secondary amines and formaldehyde in acid alcohol solvent, 10 novel prenylated chalcone Mannich base derivatives 3a-3e and 4a-4e were synthesized. Furthermore, all synthetic compounds were evaluated for antiproliferative activities in vitro against four human cancer cell lines (Aspc-1, SUN-5, HepG-2, and HCT-116) by MTT assay. The results showed that most of them exhibit moderate to good antiproliferative activities against the four human cancer cells with IC50 values of 2.52 to 47.67 mu M.

Recently, a novel negative allosteric modulator (NAM) of the D-2-like dopamine receptors 1 was identified through virtual ligand screening. This ligand comprises a thieno[2,3-d]pyrimidine scaffold that does not feature in known dopaminergic ligands. Herein, we provide pharmacological validation of an allosteric mode of action for 1, revealing that it is a NAM of dopamine efficacy and identify the structural determinants of this allostery. We find that key structural moieties are important for functional affinity and negative cooperativity, while functionalization of the thienopyrimidine at the 5- and 6-positions results in analogues with divergent cooperativity profiles. Successive compound iterations have yielded analogues exhibiting a 10-fold improvement in functional affinity, as well as enhanced negative cooperativity with dopamine affinity and efficacy. Furthermore, our study reveals a fragment-like core that maintains low mu M affinity and robust negative cooperativity with markedly improved ligand efficiency.

A novel series of 7,8-dichlorobenzofuro[3,2-c]quinoline-6,9,10(5H)-triones was obtained regioselectively in good yields. The products were formed by the reactions of the 4-hydroxy-2(1H)-quinolinones with 3,4,5,6-tetrachloro-1,2-benzoquinone in tetrahydrofuran as the solvent. Infrared, nuclear magnetic resonance (two-dimensional nuclear magnetic resonance), mass spectra and elemental analysis were used to elucidate the structures of new compounds.

Inhibition of the host RNA polyadenylating polymerases, PAPD5 and PAPD7 (PAPD5/7), with dihydroquinolizinone, a small orally available, molecule, results in a rapid and selective degradation of hepatitis B virus (HBV) RNA, and hence reduction in the amounts of viral gene products. DHQ, is a first in class investigational agent and could represent an entirely new category of HBV antivirals. PAPD5 and PAPD7 are noncanonical, cell specified, polyadenylating polymerases, also called terminal nucleotidyl transferases 4B and 4A (TENT4B/A), respectively. They are involved in the degradation of poor-quality cell transcripts, mostly noncoding RNAs and in the maturation of a sub-set of transcripts. They also appear to play a role in shielding some mRNA from degradation. The results of studies with DHQ, along with other recent findings, provide evidence that repression of the PAPD5/7 arm of the cell RNA quality control pathway, causes a profound (multifold) reduction rather than increase, in the amount of HBV pre-genomic, pre-core and HBsAg mRNA levels in tissue culture and animal models, as well. In this review we will briefly discuss the need for new HBV therapeutics and provide background about HBV transcription. We also discuss cellular degradation of host transcripts, as it relates to a new family of anti-HBV drugs that interfere with these processes. Finally, since HBV mRNA maturation appears to be selectively sensitive to PAPD5/7 inhibition in hepatocytes, we discuss the possibility of targeting host RNA quality control as an antiviral strategy.

Two new series of diethyl 2-[2-(substituted-2-oxo-1,2-dihydroquinolin-4-yl)hydrazono]-succinates 6a-g and 1-(2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazoles 7a-f have been designed and synthesized. The structures of the synthesized compounds were proved by IR, mass, NMR (2D) spectra and elemental analyses. The target compounds were evaluated for their in vitro cytotoxic activity against 60 cancer cell lines according to NCI protocol. Consequently, seven compounds were further examined against the most sensitive cell lines, leukemia CCRFCEM, and MOLT-4. 5-Amino-1-(6-bromo-2-oxo-1,2-dihydroquinolin-4-yl)-1H-pyrazole-3,4-dicarbonitrile (7f) was the most active product, with IC50= 1.35 uM and 2.42 uM against MOLT-4 and CCRF-CEM, respectively. Also, it showed a remarkable inhibitory activity compared to erlotinib on the EGFR TK with IC50 = 247.14 nM and 208.42 nM, respectively. Cell cycle analysis of MOLT-4 cells treated with 7f showed cell cycle arrest at G2/M phase (supported by Caspases, BAX and Bcl-2 studies) with a significant pro-apoptotic activity as indicated by annexin V-FITC staining. Moreover, the docking study indicated that both the pyrazole moiety and the quinolin-2-one ring showed good fitting into EGFR (PDB code: 1M17). In order to interpret SAR of the designed compounds, and provide a basis for further optimization, molecular docking of the synthesized compounds to known EGFR inhibitors was performed. The study illustrated the effect of several factors on the compounds’ activity.
