Molecular design opportunities presented by solvent-exposed regions of target proteins

Solvent-exposed regions, or solvent-filled pockets, within or adjacent to the ligand-binding?sites of drug-target?proteins provide opportunities for substantial modifications of existing small-molecular drug molecules without serious loss of activity. In this review, we present recent selected examples of exploitation of solvent-exposed regions of proteins in drug design and development from the recent medicinal-chemistry literature.

Influences of Hydrothermal Modification on Nitrogen Thermal Conversion of Low-Rank Coals

The influence of hydrothermal modification on thermal conversion of coal-N in low-rank coals was investigated in this paper. Hydrothermal modification has been performed using three typical Chinese low-rank coals at final modification temperatures of 200, 250, and 300 C. An analytical pyro-probe coupled to a pyrolysis-gas chromatography mass spectrometry (Py-GC/MS) system was used to study the release characteristics of nitrogen-containing compounds from raw and modified coal. In addition, a tube furnace apparatus was used to study the release characteristics of nitrogen pollutants during pyrolysis and combustion of Zhaotong raw and modified coal. Results showed that hydrothermal modification affected the content and type of nitrogen-containing compounds. Some triple bonds present in the coal structure are broken to form amides. The presence of azoles decreases sharply after modification, but it increases as the hydrothermal modification temperature increases. During tube furnace pyrolysis, the HCN yield decreases after modification; similarly, with the increase of modification temperature, NH3 is released in greater quantity after modification, but the release decreases as the modification temperature increases. NH3 may be converted from HCN through secondary reactions. Hydrothermal modification is conducive to NO emission reduction in coal combustion process; however, increasing the modification temperature restrains the NO emission to some extent.

One-pot homolytic aromatic substitutions/HWE olefinations under microwave conditions for the formation of a small oxindole library

(Chemical Equation Presented) An efficient one-pot sequence comprising a homolytic aromatic substitution followed by an ionic Horner Wadsworth-Emmons olefination for the preparation of a small library of alpha,beta-unsaturated oxindoles is presented. Microwave-induced heating is used to conduct these reactions. The homolytic aromatic substitution is mediated by the persistent radical effect.

Solid-State NMR and DFT Studies on the Formation of Well-Defined Silica-Supported Tantallaaziridines: From Synthesis to Catalytic Application

Single-site, well-defined, silica-supported tantallaaziridine intermediates [?Si-O-Ta(eta2-NRCH2)(NMe2)2] [R=Me (2), Ph (3)] were prepared from silica-supported tetrakis(dimethylamido)tantalum [?Si-O-Ta(NMe2)4] (1) and fully characterized by FTIR spectroscopy, elemental analysis, and 1H,13C HETCOR and DQ TQ solid-state (SS) NMR spectroscopy. The formation mechanism, by beta-H abstraction, was investigated by SS NMR spectroscopy and supported by DFT calculations. The C-H activation of the dimethylamide ligand is favored for R=Ph. The results from catalytic testing in the hydroaminoalkylation of alkenes were consistent with the N-alkyl aryl amine substrates being more efficient than N-dialkyl amines.

Structural and biochemical study on the inhibitory activity of derivatives of 5-nitro-furan-2-carboxylic acid for RNase H function of HIV-1 reverse transcriptase

Rapid emergence of drug-resistant variants is one of the most serious problems in chemotherapy for HIV-1 infectious diseases. Inhibitors acting on a target not addressed by approved drugs are of great importance to suppress drug-resistant viruses. HIV-1 reverse transcriptase has two enzymatic functions, DNA polymerase and RNase H activities. The RNase H activity is an attractive target for a new class of antiviral drugs. On the basis of the hit chemicals found in our previous screening with 20,000 small molecular-weight compounds, we synthesized derivatives of 5-nitro-furan-2-carboxylic acid. Inhibition of RNase H enzymatic activity was measured in a biochemical assay with real-time monitoring of florescence emission from the digested RNA substrate. Several derivatives showed higher inhibitory activities that those of the hit chemicals. Modulation of the 5-nitro-furan-2-carboxylic moiety resulted in a drastic decrease in inhibitory potency. In contrast, many derivatives with modulation of other parts retained inhibitory activities to varying degrees. These findings suggest the binding mode of active derivatives, in which three oxygen atoms aligned in a straight form at the nitro-furan moiety are coordinated to two divalent metal ions located at RNase H reaction site. Hence, the nitro-furan-carboxylic moiety is one of the critical scaffolds for RNase H inhibition. Of note, the RNase H inhibitory potency of a derivative was improved by 18-fold compared with that of the original hit compound, and no significant cytotoxicity was observed for most of the derivatives showing inhibitory activity. Since there is still much room for modification of the compounds at the part opposite the nitro-furan moiety, further chemical conversion will lead to improvement of compound potency and specificity.

Discovery of N-(4-methoxyphenyl)-N,2-dimethylquinazolin-4-amine, a potent apoptosis inducer and efficacious anticancer agent with high blood brain barrier penetration

As a continuation of our structure-activity relationship (SAR) studies on 4-anilinoquinazolines as potent apoptosis inducers and to identify anticancer development candidates, we explored the replacement of the 2-Cl group in our lead compound 2-chloro-N-(4-methoxyphenyl)-N-methylquinazolin-4-amine (6b, EP128265, MPI-0441138) by other functional groups. This SAR study and lead optimization resulted in the identification of N-(4-methoxyphenyl)-N,2- dimethylquinazolin-4-amine (6h, EP128495, MPC-6827) as an anticancer clinical candidate. Compound 6h was found to be a potent apoptosis inducer with EC 50 of 2 nM in our cell-based apoptosis induction assay. It also has excellent blood brain barrier penetration, and is highly efficacious in human MX-1 breast and other mouse xenograft cancer models.
