The collaborative development through multidisciplinary and advocate consensus of an accessible notice of rights for people with intellectual disabilities in police custody.

Background People with intellectual disabilities are over-represented in the criminal justice system. The United Nations' Convention on the Rights of Persons with Disabilities (UNCRPD) enshrines a right to equal access to justice for persons with disabilities (Article 13, UNCRPD). Accessible information is a key aspect of exercising this right. Yet, many jurisdictions, including Ireland, are yet to develop accessible information for disabled people who may be arrested. Aims This paper describes the collaborative development through multidisciplinary and advocate consensus of an accessible (Easy -to- Read) Notice of Rights (ERNR) for people with intellectual disabilities in police custody in Ireland. Methods Guidelines developed by Ireland's representative organisation for people with intellectual disabilities and examples of international practice were used to develop a draft ERNR by the primary researcher in partnership with an expert from a representative organisation for people with intellectual disabilities. The ERNR was developed thereafter through two focus groups with a view to achieving consensus with a focus on accessibility, accuracy and layout. This included a multidisciplinary focus group with participants from a representative organisation for people with intellectual disabilities, psychology, speech and language therapy, the police force, public health, forensic psychiatry, mental health, law and, subsequently, a focus group of people with lived experience of intellectual disability. Results Progressive development of the ERNR resulted in incremental improvements in textual accuracy as well as the inclusion of more accessible language and imagery. Originality/value This is the first attempt at developing an easy-to-read document relating to the legal rights of suspects in police custody in Ireland and, accordingly, this procedural innovation promises to assist, not just persons with intellectual disabilities, but also those with limited literacy at the point of arrest. The methodology used in the preparation of the document, employing a focus group to achieve consensus with participation from both multiple disciplines and persons with an intellectual disability, is in harmony with the ethos of the UNCPRD. This methodology may usefully be employed by other member states that have ratified the Convention but have yet to develop accessible version of the legal rights and entitlements that extend to arrested persons under their domestic law.

Identification of small molecule inhibitors of proline-rich tyrosine kinase 2 (Pyk2) with osteogenic activity in osteoblast cells.

A screening campaign of a diverse collection of approximately 250,000 small molecule compounds was performed to identify inhibitors of proline-rich tyrosine kinase 2 (Pyk2) with potential osteogenic activity in osteoblast cells. Compounds were prioritized based on selectivity following a counter-screen against focal adhesion kinase (FAK), a closely related kinase. 4-Amino and 5-aryl substituted pyridinone series were identified that showed strong biochemical potency against Pyk2 and up to 3700-fold selectivity over FAK. Modeling analysis suggested that structural differences in the substrate binding cleft could explain the high selectivity of these chemical series against FAK. Representative compounds from each series showed inhibition of Pyk2 autophosphorylation in 293T cells (IC(50) approximately 0.11 microM), complete inhibition of endogenous Pyk2 in A7r5 cells and increased levels of osteogenic markers in MC3T3 osteoblast cells (EC(50)'s approximately 0.01 microM). These results revealed a new class of compounds with osteogenic-inducing activity in osteoblast cells and a starting point for the development of more potent and selective Pyk2 inhibitors.

c-Met inhibitors with novel binding mode show activity against several hereditary papillary renal cell carcinoma-related mutations.

c-Met is a receptor tyrosine kinase often deregulated in human cancers, thus making it an attractive drug target. One mechanism by which c-Met deregulation leads to cancer is through gain-of-function mutations. Therefore, small molecules capable of targeting these mutations could offer therapeutic benefits for affected patients. SU11274 was recently described and reported to inhibit the activity of the wild-type and some mutant forms of c-Met, whereas other mutants are resistant to inhibition. We identified a novel series of c-Met small molecule inhibitors that are active against multiple mutants previously identified in hereditary papillary renal cell carcinoma patients. AM7 is active against wild-type c-Met as well as several mutants, inhibits c-Met-mediated signaling in MKN-45 and U-87 MG cells, and inhibits tumor growth in these two models grown as xenografts. The crystal structures of AM7 and SU11274 bound to unphosphorylated c-Met have been determined. The AM7 structure reveals a novel binding mode compared with other published c-Met inhibitors and SU11274. The molecule binds the kinase linker and then extends into a new hydrophobic binding site. This binding site is created by a significant movement of the C-helix and so represents an inactive conformation of the c-Met kinase. Thus, our results demonstrate that it is possible to identify and design inhibitors that will likely be active against mutants found in different cancers.
