      Zheng-Kun Kuang, Shi-Yu Feng, Ben Hu, Dong Wang, Song-Bing He and De-Xin Kong

      Version of Record online: 29 JUL 2016 | DOI: 10.1111/cbdd.12815

      We applied a novel molecular descriptor, three-dimensional biologically relevant spectrum (BRS-3D), in subtype selectivity prediction of dopamine receptor (DR) ligands. BRS-3D is calculated by superposing the objective compounds against 300 template ligands from sc-PDB; it can encode the ligand's multiple conformations into a similarity array. BRS-3D-based method provided a new strategy for the selectivity prediction of structurally diverse ligands.

    1. Biohydroxylation of 7-oxo-DHEA, a natural metabolite of DHEA, resulting in formation of new metabolites of potential pharmaceutical interest

      New oxygenated metabolites of biologically active 7-oxo-DHEA were formed by fungal stereoselective hydroxylations by Syncephalastrum racemosum. The studies demonstrated that the obtained derivatives may be simultaneously the final metabolites of DHEA. The observed reactions suggested that this micro-organism contains enzymes exhibiting similar activity to those present in human cells. The resulting compounds can be considered as potential components of the eukaryotic, including human, metabolome.

      We designed new structurally simplified trimethoxy benzamides to detect the minimal molecular requirements for P-gp modulation. The proposed ligands were provided with a high efficiency and IC50 values in the low micromolar range. By employing DFT and NMR approaches, we found a clear rationale bridging molecular flatness and P-gp modulation.

      The known inhibitors except in polycyclic aromatic hydrocarbons and selected ligands derived from docking of CYP1B1 is found to be at a optimum distance 6 Å of heme (Fe) to nearest non-hydrogen atom. The Cluster 1 was largest one containing 94 compounds using LibMCS classification. ∆Evdw component played dominant role in deciding binding energies of ligands, ∆Eele component supported in some ligands. The residues Ser131, Asp326, Asp333, and Thr510 were frequently involved in hydrogen bond formation in CYP1B1 interactions with ligands.

      The pharmacomodulation and the synthesis of 15 new (aza)isoindolinone-type compounds were described. Two of them were more effective InhA inhibitors than the hit molecule. The modes of interaction of the (aza)isoindolinones with this enzyme were predicted based on molecular docking calculations and on the structure–activity relationship analysis. The (aza)isoindolinone exhibited only a discrete inhibitory activity upon M. tuberculosis H37Rv growth. Compounds m-4a and 2a were not able to inhibit the biosynthesis of mycolic acids.

      Most of the compounds demonstrated cytotoxic activity at submicromolar concentrations. Oxidation of sulfur atom of the oxathiole-fused chalcones strongly influenced activity of the parent compounds, and depending on relative position of the sulfur atom in the molecule, the activity was either increased or diminished. It was demonstrated that the compounds interact with tubulin at the colchicine binding site.

      Self-docking is performed using GOLD ChemPLP. It is shown that rescoring ChemPLP poses with the Molecular Mechanics/Generalized Born Surface Area scoring function improves pose ranking by better discriminating against non-cognate-like poses. In this example, the best pose according to the ChemPLP scoring function has a heavy atom RMSD of 4.7 Å relative to the cognate pose (pink). The MM-GBSA scoring function assigns the best rank to the pose ranked second by GOLD ChemPLP (blue). After the minimization step, the heavy atom RMSD is 0.3 Å relative to the cognate.

      The ursane triterpenoids, asiatic acid 1 and madecassic acid 2, exhibit selective negative modulation of different subtypes of the GABAA receptor expressed in Xenopus laevis oocytes. Despite differing by only one hydroxyl group, asiatic acid 1 was shown to be a negative modulator of the GABA-induced current at α1β2γ2L (IC50 37.05 μm), followed by α5β3γ2L (IC50 64.05 μm) then α2β2γ2L (IC50 427.2 μm) GABAA receptors, while madecassic acid 2 is not.

      Mesoporous silica nanoparticles of SBA-15 have been synthesized and characterized. They were functionalized with aminopropyl, AP@SBA-15. Loading of non-steroidal anti-inflammatory drugs was performed and release profile of these drugs in the simulated gastrointestinal environment were evaluated.

      A synthetic strategy that integrates quantitative sequence-activity modeling, genetic evolution, dynamics simulation and in vitro assay is described to rationally design antimicrobial peptides containing unnatural amino acids. Four unnatural peptides are successfully identified to have high antibacterial potency, which can fold into amphipathic helical structure.

      Using the proteochemometric approach (PCM), we could find remarkable information that can be taken into consideration for designing inhibitors with the ability of selective inhibition of either cytosolic isoforms or transmembrane isoforms of carbonic anhydrase.

      Ten targeted uridine–oleanolic acid hybrids were synthesized. Most of these hybrids showed excellent proliferation inhibition against tested Hep-G2, A549, BGC-823, MCF-7, and PC-3 tumor cell lines (IC50 < 8 μm), even with some IC50 values of them under 0.1 μm.
