Measles virus (MV) is one of the most infectious pathogens known. Despite the existence of a vaccine, over 500 000 deaths/year result from MV or associated complications. Anti-measles compounds could conceivably reverse these statistics. Previously, we described a homology model of the MV fusion protein trimer and a putative binding site near the head-neck region. The resulting model permitted the identification of two nonpeptidic entry inhibitors. Here, we present the design, synthesis, and bioevaluation of several series of fusion inhibitors and describe their structure-activity relationships (SAR). Five simply substituted anilides show low-μM blockade of the MV, one of which (AS-48) exhibits IC50 = 0.6-3.0 μM across a panel of wild-type MV strains found in the field. Molecular field topology analysis (MFTA), a 2D QSAR approach based on local molecular properties (atomic charges, hydrogen-bonding capacity and local lipophilicity), applied to the anilide series suggests structural modifications to improve potency.

From a library of 61 compounds available from former studies, 2,5-bis-acylaminobenzophenone 1 was identified as a lead structure for a novel class of anti-malaria agents active against multi-resistant Plasmodium falciparum strain Dd2. Some structural modifications of this initial lead demonstrated the potential for further improvement of the anti-plasmodial activity of this novel class of anti-malarials. Copyright
