The antimalarial MMV688533 provides potential for single-dose cures with a high barrier to parasite resistance.

The emergence and spread of resistance to first-line antimalarials creates an imperative to identify and develop potent preclinical candidates with distinct modes of action. Here, we report the identification of MMV688533, an acylguanidine that was developed following a whole-cell screen with compounds known to hit high-value targets in human cells. MMV688533 displays fast parasite clearance in vitro and is not cross-resistant with known antimalarials.

11q24.2q24.3 microdeletion in two families presenting features of Jacobsen syndrome, without intellectual disability: Role of FLI1, ETS1, and SENCR long noncoding RNA.

This report presents two families with interstitial 11q24.2q24.3 deletion, associated with malformations, hematologic features, and typical facial dysmorphism, observed in Jacobsen syndrome (JS), except for intellectual disability (ID).

Search for Rare Copy-Number Variants in Congenital Heart Defects Identifies Novel Candidate Genes and a Potential Role for FOXC1 in Patients With Coarctation of the Aorta.

Background: Congenital heart defects are the most frequent malformations among newborns and a frequent cause of morbidity and mortality. Although genetic variation contributes to congenital heart defects, their precise molecular bases remain unknown in the majority of patients.

Methods And Results: We analyzed, by high-resolution array comparative genomic hybridization, 316 children with sporadic, nonsyndromic congenital heart defects, including 76 coarctation of the aorta, 159 transposition of the great arteries, and 81 tetralogy of Fallot, as well as their unaffected parents.

Synthesis and multiparametric evaluation of thiadiazoles and oxadiazoles as diacylglycerol acyltransferase type 1 inhibitors.

Chemical modulation of a formerly disclosed DGAT-1 inhibitor resulted in the identification of a compound with a suitable profile for preclinical development. Optimisation of solubility is discussed and a PK/PD study is presented.

Discovery of SAR184841, a potent and long-lasting inhibitor of 11β-hydroxysteroid dehydrogenase type 1, active in a physiopathological animal model of T2D.

Starting from 11β-HSD1 inhibitors that were active ex vivo but with Cyp 3A4 liability, we obtained a new series of adamantane ureas displaying potent inhibition of both human and rodent 11β-HSD1 enzymes, devoid of Cyp 3A4 interactions, and rationally designed to provide long-lasting inhibition in target tissues. Final optimizations lead to SAR184841 with good oral pharmacokinetic properties showing in vivo activity and improvement of metabolic parameters in a physiopathological model of type 2 diabetes.

Thiadiazoles as new inhibitors of diacylglycerol acyltransferase type 1.

A novel class of DGAT1 inhibitors containing a thiadiazole core has been discovered. Chemical optimization lead to inhibitors of human DGAT1 with an appropriate ADME profile and that show in vivo activity in target tissues.

Pyrrolidine-pyrazole ureas as potent and selective inhibitors of 11β-hydroxysteroid-dehydrogenase type 1.

A High Throughput Screening campaign allowed the identification of a novel class of ureas as 11β-HSD1 inhibitors. Rational chemical optimization provided potent and selective inhibitors of both human and murine 11β-HSD1 with an appropriate ADME profile and ex vivo activity in target tissues.

Isolated left ventricular non-compaction in adults: clinical and echocardiographic features in 105 patients. Results from a French registry.

Aims: The clinical features, prognosis, and even definition of left ventricular non-compaction (LVNC) are still the subject of much debate. The aim of this registry was to describe the clinical, echocardiographic, and prognostic features of LVNC in France. The main endpoint was to assess clinical and echocardiographic predictors of adverse outcome, defined as death or heart transplantation.

An echocardiographic study of diagnostic accuracy, prediction of surgical approach, and outcome for fetuses diagnosed with discordant ventriculo-arterial connections.

Our aims were to examine the diagnostic accuracy of prenatal diagnosis of concordant atrioventricular and discordant ventriculo-arterial connections, the accuracy of predictions made concerning the postnatal surgical approach, and a description of the different subtypes related to outcome. All fetuses were evaluated at a tertiary centre for fetal cardiology between January, 1994, and December, 2003. In this period, we identified congenitally malformed hearts in 1,835 fetuses, of whom 56 (3%) met the criterions of inclusion.

Functional consequences of an LMNA mutation associated with a new cardiac and non-cardiac phenotype.

Heritable dilated cardiomyopathy is a genetically highly heterogeneous disease. To date 17 different chromosomal loci have been described for autosomal dominant forms of dilated cardiomyopathy with or without additional clinical manifestations. Among the 10 mutated genes associated with dilated cardiomyopathy, the lamin A/C (LMNA) gene has been reported in forms associated with conduction-system disease with or without skeletal muscle myopathy.
