[[http://www.uniprot.org/uniprot/DYR1A_HUMAN DYR1A_HUMAN]] Defects in DYRK1A are the cause of mental retardation autosomal dominant type 7 (MRD7) [MIM:[http://omim.org/entry/614104 614104]]. A disease characterized by primary microcephaly, severe mental retardation without speech, anxious autistic behavior, and dysmorphic features, including bitemporal narrowing, deep-set eyes, large simple ears, and a pointed nasal tip. Mental retardation is characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period.<ref>PMID:21294719</ref> | |||

== Publication Abstract from PubMed == | |||
Recently, our group identified that harmine is able to induce beta-cell proliferation both in vitro and in vivo, mediated via the DYRK1A-NFAT pathway. Since, harmine suffers from lack of selectivity, both against other kinases and CNS off-targets, therefore, we sought to expand structure-activity relationships for harmine's DYRK1A activity, to enhance selectivity for off-targets, while retaining human beta-cell proliferation activity. We carried out optimization of the 9-N-position of harmine to synthesize 29 harmine-based analogs. Several novel inhibitors showed excellent DYRK1A inhibition and human beta-cell proliferation capability. An optimized DYRK1A inhibitor, 2-2c, was identified as a novel, efficacious in vivo lead candidate. 2-2c also demonstrates improved selectivity for kinases and CNS off-targets, as well as in vivo efficacy for beta-cell proliferation and regeneration at lower doses than harmine. Collectively, these findings demonstrate that 2-2c is a much-improved in vivo lead candidate as compared to harmine, for the treatment of diabetes. | |||
