      Version of Record online: 29 NOV 2016 | DOI: 10.1111/cbdd.12903

      Thumbnail image of graphical abstract

      mTAAR2 and hTAAR2 homology models have been built for the first time. At present, only 3-iodothyronamine (T1AM) acts as TAAR2 ligand, being also able to bind other TAARs, making the discovery of selective compounds an urgent need to derive efficient tools for studying this family of receptors. The two models have been compared with those we previously built about the mTAAR1 and hTAAR1 receptors. New insights guiding for species specificity and selectivity between the TAAR1 and TAAR2 receptors have been derived.

      Molecular dynamics simulations were performed to illustrate the molecular mechanism for allosteric regulation of Akt1 kinase phosphorylation by binding of ATP-competitive inhibitor GDC-0068 to the ATP-binding site. We propose a potential mechanism and identify a communication pathway from GDC-0068 to pT308 in Akt1. This result yields important new insights into the molecular mechanism of allosteric regulation of Akt kinase activity.

      Fifteen flavonoids were studied for their inhibitory activity against human dipeptidyl peptidase III (hDPP III) combining an in vitro assay with an in silico molecular modeling study. All analyzed flavonoids showed inhibitory effects against hDPP III; 3D QSAR studies indicate that the presence of hydrophilic regions at a flavonoid molecule increases its inhibitory activity while molecular dynamics results clearly provide valuable information explaining the importance of flavonoid hydroxyl groups in the mechanism for the binding pattern at the active site of hDPP III.

      The in vitro trials revealed that the presence of aspirin elevated the potency of 6k against tumor cells. The in vivo trials on three H22 tumor transplant models demonstrated that the combination of 6k and aspirin markedly improved the efficacy in terms of inhibitive effect, pulmonary metastasis, and extension of the life span. More importantly, the combination of 6k and aspirin displayed the reduced side effects compared to that of amonafide.

    1. Computed insight into a peptide inhibitor preventing the induced fit mechanism of MurA enzyme from Pseudomonas aeruginosa

      Anderson H. Lima, Alberto M. dos Santos, Cláudio Nahum Alves and Jerônimo Lameira

      Version of Record online: 16 NOV 2016 | DOI: 10.1111/cbdd.12882

      In this article, theoretical simulations were used to analyze, for the first time, the interaction of the PEP 1354 peptide with MurA enzyme from Pseudomonas aeruginosa. Our modeling results suggest that the peptide binds to the same active site of the natural substrate UDP-N-acetylglucosamine. Additionally, the MurA–peptide complex reveals that the peptide seems to act preventing the closure of the loop Pro114-123 and consequently, the open–closed transition of MurA structure.

      Two silver nanoparticle aqueous solutions NanoAg1 and NanoAg2 varying in size and shape were developed by one-step chemical reduction with the involvement of tannic acid. NanoAg1 and NanoAg2 significantly ameliorated colitis in mouse models of colonic inflammation mimicking human ulcerative colitis and Crohn's disease.

      We utilized the free and open-source protein–ligand docking software idock to prospectively identify potential inhibitors of FGFR3. The fluazuron exhibited the highest anticancer effect in human bladder carcinoma cell lines, RT112 and RT4, and inhibited the FGFR3 signaling pathway in vitro. Oral treatment with fluazuron significantly inhibited tumor growth in BALB/C nude mice. These results suggested for the first time that fluazuron is a potential inhibitor of FGFR3 and a candidate anticancer drug for the treatment of bladder cancer.

      In this study, for the first time, a series of short hybrid antimicrobial peptides (SHAMPs) combined by different fragments of venom-derived α-helical antimicrobial peptides pEM-2, mastoparan-VT1 (MP-VT1), and mastoparan-B (MP-B) were designed. All peptides had membrane-disrupting activity in a time-dependent manner. Collectively, current study highlights the potential for rational design of improved SHAMPs such as PV3 that was an ideal candidate for further assessment with the ultimate purpose of development of effective antimicrobial agents.

      The human cytomegalovirus-encoded G protein-coupled receptor US28 is a constitutively active receptor for various chemokines. Despite the recent determination of its 2.9 Å crystal structure, potent and US28-specific tool compounds are still scarce. Here, we used structural information from a refined US28:VUF2274 complex for virtual screening of >12 million commercially available screening compounds. We tested 98 of the top 0.1% ranked compounds, revealing novel chemotypes with distinct pharmacological profiles – agonist and inverse agonist.

      A new library of flavone derivatives targeting two active sites of MAOs (“Aromatic Cage” and substrate cavity) were designed and synthesized using click chemistry (CuAAC reaction). The most potent flavone MAO inhibitor studied is Az2k19 (1.6 μm for MAO-A, 2.1 μm for MAO-B), while Az1k15 and Az2k15 displayed better selectivity toward MAO-B (SI > 10). Docking studies are in accordance with our hypothesis that this series inhibitors are most likely located at the substrate cavity and the “aromatic cage”.

The enzyme follows Michaelis–Menten kinetics to catalyze substrates such as trimethylamine and thiourea. Molecular docking studies revealed that isoniazid targeted NADPH-binding site of the MymA. Further, experimental validation revealed that isoniazid inhibits MymA with the IC50 value of 4.9 μm.
