Biochem/physiol Actions

FRAX486 is a potent, group I-selective p21-activated kinase (PAK) inhibitor (PAK1/2/3 IC50 = 8.25/39.5/55.3 nM; group II PAK4 IC50 = 779 nM). FRAX486 effectively inhibits PAK-mediated PKD1 Ser203 phosphorylation and PAK1/2 Ser144/141 autophosphorylation upon angiotensin II (ANGII) stimulation of rat IEC-18 cells (IC50 ∼0.5 μM) and exhibits in vivo efficacy in rescuing the autism-like phenotypes among Fmr1 knockout fragile syndrome (FXS) mice (20 mg/kg s.c.) as well as in ameliorating schizophrenia-associated dendritic spine deterioration among Disc1 knockdown mice (10 μg/g or 10 mg/kg i.p.) with good pharmacokinetic properties and blood–brain barrier (BBB) permeability.

Drug discovery in psychiatry has been limited to chemical modifications of compounds originally discovered serendipitously. Therefore, more mechanism-oriented strategies of drug discovery for mental disorders are awaited. Schizophrenia is a devastating mental disorder with synaptic disconnectivity involved in its pathophysiology.

Fragile X syndrome (FXS) is the most common inherited cause of intellectual disabilities and a leading cause of autism. FXS is caused by a trinucleotide expansion in the gene FMR1 on the X chromosome. The neuroanatomical hallmark of FXS is

Mutations in GFI1B are associated with inherited bleeding disorders called GFI1B-related thrombocytopenias. We show here that mice with a megakaryocyte-specific Gfi1b deletion exhibit a macrothrombocytopenic phenotype along a megakaryocytic dysplasia reminiscent of GFI1B-related thrombocytopenia. GFI1B deficiency increases megakaryocyte proliferation and

Precise regulation of the dendritic spine actin cytoskeleton is critical for neurodevelopment and neuronal plasticity, but how neurons spatially control actin dynamics is not well defined. Here, we identify direct palmitoylation of the actin regulator LIM kinase-1 (LIMK1) as a

The discovery of inhibitors targeting novel allosteric kinase sites is very challenging. Such compounds, however, once identified could offer exquisite levels of selectivity across the kinome. Herein we report our structure-based optimization strategy of a dibenzodiazepine hit 1, discovered in
