A method for the solid-phase synthesis of disubstituted guanidines is reported. In this procedure, polymer-bound aryl or alkyl amines are converted to methyl isothioureas in three steps and treated with primary and secondary amines to form the disubstitut
Beyond Basicity: Discovery of Nonbasic DENV-2 Protease Inhibitors with Potent Activity in Cell Culture

The viral serine protease NS2B-NS3 is one of the promising targets for drug discovery against dengue virus and other flaviviruses. The molecular recognition preferences of the protease favor basic, positively charged moieties as substrates and inhibitors, which leads to pharmacokinetic liabilities and off-target interactions with host proteases such as thrombin. We here present the results of efforts that were aimed specifically at the discovery and development of noncharged, small-molecular inhibitors of the flaviviral proteases. A key factor in the discovery of these compounds was a cellular reporter gene assay for the dengue protease, the DENV2proHeLa system. Extensive structure-activity relationship explorations resulted in novel benzamide derivatives with submicromolar activities in viral replication assays (EC50 0.24 μM), selectivity against off-target proteases, and negligible cytotoxicity. This structural class has increased drug-likeness compared to most of the previously published active-site-directed flaviviral protease inhibitors and includes promising candidates for further preclinical development.
Virtues of Volatility: A Facile Transesterification Approach to Boronic Acids

Boronic acids are an increasingly important compound class for many applications, including C-C bond formation reactions, medicinal chemistry, and diagnostics. The deprotection of boronic ester intermediates is frequently a problematic and inefficient step in boronic acid syntheses. We describe an approach that highly facilitates this transformation by leveraging the volatility of methylboronic acid and its diol esters. The method is performed under mild conditions, provides high yields, and eliminates cumbersome and problematic purification steps.

In particular we have identified novel compounds which enhance the entry of L-arginine into cells. These compounds improve endothelial function, and thereby have the potential to retard the progression of vascular disease in conditions such as hypertension, heart failure and diabetes. This new class of drugs may also have other potentially, relevant pharmacological actions, including anti-hypertensive and anti-anginal actions.
