Currently, there are more than 65 million people at risk of contracting sleeping sickness caused by Trypanosoma brucei. Available treatments for this parasitic disease are limited and have side effects. There is a necessity to investigate novel, effective compounds that also yield low in toxicity. Quantitative Structure-Activity Relationship models (QSAR) have been used in this study for predicting anti-Trypanosoma brucei activity and potency in a group of dicationic 3,5-Diphenylisoxazoles. Linear Discriminant Analysis (LDA) correctly classified anti-Trypanosoma brucei activity in 100 % of cases (sensitivity) and inactivity in 86.7 % (specificity). Theoretical bioactivity (pIC50) of the studied compounds was predicted using Multilinear Regression Analysis (MLRA), demonstrating a high correlation between in vitro and in silico results (r2=0.82). Topologic models obtained with LDA and MLRA were applied to the screening of a group of dicationic analogs which presented a high in silico activity. These compounds when selected for in vitro analysis could reduce both time and costs in future drug research.

The HIV-1 capsid (CA) protein plays essential roles in both early and late stages of HIV-1 replication and is considered an important, clinically unexploited therapeutic target. As such, small drug-like molecules that inhibit this critical HIV-1 protein have become a priority for several groups. Therefore, in this study we explore small molecule targeting of the CA protein, and in particular a very attractive inter-protomer pocket. We report the design, parallel synthesis, and anti-HIV-1 activity evaluation of a series of novel phenylalanine derivatives as HIV-1 CA protein inhibitors synthesized via Cu(I)-catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuAAC) reaction. We demonstrate robust inhibitory activity over a range of potencies against the HIV-1 NL4-3 reference strain. In particular, compound 13m exhibited the greatest potency and lowest toxicity within this new series with an EC50 value of 4.33 muM and CC50 value of >57.74 muM (SI > 13.33). These values are very similar to the lead compound PF-74 (EC50 = 5.95 muM, CC50 > 70.50 muM, SI > 11.85) in our assay, despite significant structural difference. Furthermore, we demonstrate via surface plasmon resonance (SPR) binding assays that 13m interacts robustly with recombinant HIV-1 CA and exhibits antiviral activity in both the early and late stages of HIV-1 replication. Overall, the novel parallel synthesis and structure-activity relationships (SARs) identified within this study set the foundation for further rational optimization and discovery of CA-targeting compounds with improved potency.

1,3-Dipolar cycloaddition reaction of trimethylstannylacetylene with nitrile oxides yielded 3-substituted 5-(trimethylstannyl)isoxazoles. On the other hand, the same reaction of (trimethylstannyl)phenylacetylene, -1-hexyne, and -(trimethylsilyl)acetylene gave 3,5-disubstituted 4-(trimethylstannyl)isoxazoles almost regioselectively. The regioselectivity of the cycloaddition reaction is interpreted by application of the frontier-electron theory.

A KI-mediated multi-component cyclocondensation of hydroxylamine hydrochloride, aromatic/hetero-aromatic aldehydes, and ethyl acetoacetate or 4-chloroethyl acetoacetate to form isoxazole-5(4H)-one heterocycles is described. The reaction employs readily accessible starting reactants and provides a range of synthetically isoxazole-5(4H)-ones in good to high yields. Reactions were performed in water as a green medium at room temperature (rt) without heating, microwave irradiation or sonication. Reusability of the reaction medium is also a noteworthy characteristic of this reaction.
