A virtual screening conducted with nearly 4 000 000 compounds from lead-like and fragment-like subsets enabled the identification of a small-molecule inhibitor (1) of the Trypanosoma cruzi cruzain enzyme, a validated drug target for Chagas disease. Subsequent comprehensive structure-based drug design and structure-activity relationship studies led to the discovery of carbamoyl imidazoles as potent, reversible, and competitive cruzain inhibitors. The most potent carbamoyl imidazole inhibitor (45) exhibited high affinity with a K-i value of 20 nM, presenting both in vitro and in vivo activity against T. cruzi. Furthermore, the most promising compounds reduced parasite burden in vivo and showed no toxicity at a dose of 100 mg/kg. These carbamoyl imidazoles are structurally attractive, nonpeptidic, and easy to prepare and synthetically modify. Finally, these results further advance our understanding of the noncovalent mode of inhibition of this pharmaceutically relevant enzyme, building strong foundations for drug discovery efforts.

Fingerprint development is one of the most useful techniques in forensic investigation. The powder method is widely used, as it consists of a non-destructive testing. However, some of the powders commonly used are toxic and dangerous to human health. In this sense, monofunctional analogues of curcumin (3a-e) are proposed as novel coloring powders for the development of latent fingerprints. Granulometric and scanning electron microscopy analysis were performed for a better understanding of the interaction between developers and substrates. The best results for the development of fingerprints were obtained with compound (1E,4E)-1,5-di-p-tolylpenta-1,4-dien-3-one (3b). Development with this compound was specific and allowed detection both from male and female donors. Also, in an in vitro experiment, compound 3b presented low cytotoxicity in a mammalian cell line. Based on that, a novel alternative for latent fingerprint developers was proposed.

DNA-encoded combinatorial chemical library (DEL) technology, an approach that combines the power of genetics and chemistry, has emerged as an invaluable tool in drug discovery. Skeletal diversity plays a fundamental importance in DEL applications, and relies heavily on novel DNA-compatible chemical reactions. We report herein a phylogenic chemical transformation strategy using DNA-conjugated benzoyl hydrazine as a common versatile precursor in azole chemical expansion of DELs. DNA-compatible reactions deriving from the common benzoyl hydrazine precursor showed excellent functional group tolerance with exceptional efficiency in the synthesis of various azoles, including oxadiazoles, thiadiazoles, and triazoles, under mild reaction conditions. The phylogenic chemical transformation strategy provides DELs a facile way to expand into various unique chemical spaces with privileged scaffolds and pharmacophores.

Development of tunable photonic devices having molecular dimensions is an active research area in nonlinear optics which continues to evolve and impact many technologies. Here, we demonstrate the tailoring of nonlinear optical properties of nitrochalcone derivatives by engineering the donor-acceptor configurations on either end of the molecules, to control the intramolecular charge transfer process. The central pi-bridge in chalcones provides delocalized electrons which lead to the nonlinear polarizability observed in these molecules. Optical nonlinearity is studied by means of second harmonic generation (SHG) and open aperture Z-scan measurements. Samples show optical limiting behaviour in the nanosecond excitation regime due to excited state absorption (ESA) and two-photon absorption (2PA) phenomena. Our study highlights the importance of structure-property correlations in molecular designs.

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one-pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23-90 degrees C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with a wide variety of useful functional groups and were successfully applied as chiral ligands for metal catalysis. Computational studies gave a first rationalization of the low activation energy for the cycloaddition based on counter-intuitive favorable dispersive interactions in the transition state.

A one-pot, Hantzsch ester-mediated Knoevenagel condensation-reduction reaction has been developed for alkylation of a wide range of substituted 2,4-quinoline diols and 2,4-pyridine diols with aldehydes. The process is operationally simple to perform, scalable, and provides highly useful C-3 alkylated quinoline and pyridine diols in yields of 58-92%. The alkylation products can be converted to 2,4-dihaloquinoline and pyridine substrates for further functionalization.

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.

Cerebral amyloid angiopathy (CAA) commonly found in the aged is pathologically characterized by beta-amyloid (A beta) deposition in the walls of arteries and capillaries of brain. In this study, four flexible multidentate benzyldiamine derivatives as potential probes for cerebrovascular A beta deposition were designed and synthesized. In in vitro inhibition assays, the ligands 18-21 displayed high affinities for A beta aggregates with K-i values of 1.45 +/- 0.53 nM, 1.68 +/- 0.35 nM, 1.16 +/- 0.23 nM and 1.72 +/- 0.19 nM, respectively. A significant improvement in the binding affinity over the monomer, compounds 9-12 or benzyldiamine derivatives, demonstrated the applicability of the multidentate approach. The underlying mechanism of these novel A beta agents was explored by molecular docking technique, which theoretically verified the high affinities of the multidentate benzyldiamine derivatives for A beta aggregates. Moreover, the molecular masses of the ligands 18-21 are more than 700 Dalton, which are believed to be hardly capable of penetrating blood brain barrier. In this regard, these ligands could be used to distinguish CAA from Alzheimer’s disease which is another A beta-related disorder disease. To convert these ligands to positron emission tomography imaging agents, we attempted to radiosynthesize [F-18]18. Though the radiolabeling was not very successful, the preliminary results suggested that these newly proposed multidentate benzyldiamine derivatives may be used as potential A beta imaging agents in cerebral amyloid angiopathy.
