Accelerated Discovery of Carbamate Cbl-b Inhibitors Using Generative AI Models and Structure-Based Drug Design.

Casitas B-lymphoma proto-oncogene-b (Cbl-b) is a RING finger E3 ligase that has an important role in effector T cell function, acting as a negative regulator of T cell, natural killer (NK) cell, and B cell activation. A discovery effort toward Cbl-b inhibitors was pursued in which a generative AI design engine, REINVENT, was combined with a medicinal chemistry structure-based design to discover novel inhibitors of Cbl-b. Key to the success of this effort was the evolution of the "Design" phase of the Design-Make-Test-Analyze cycle to involve iterative rounds of an in silico structure-based drug design, strongly guided by physics-based affinity prediction and machine learning DMPK predictive models, prior to selection for synthesis.

Discovery, Optimization, and Biological Evaluation of Arylpyridones as Cbl-b Inhibitors.

Casitas B-lymphoma proto-oncogene-b (Cbl-b), a member of the Cbl family of RING finger E3 ubiquitin ligases, has been demonstrated to play a central role in regulating effector T-cell function. Multiple studies using gene-targeting approaches have provided direct evidence that Cbl-b negatively regulates T, B, and NK cell activation via a ubiquitin-mediated protein modulation. Thus, inhibition of Cbl-b ligase activity can lead to immune activation and has therapeutic potential in immuno-oncology.

Discovery of a Novel Benzodiazepine Series of Cbl-b Inhibitors for the Enhancement of Antitumor Immunity.

Casitas B-lineage lymphoma proto-oncogene-b (Cbl-b) is a RING finger E3 ligase that is responsible for repressing T-cell, natural killer (NK) cell, and B-cell activation. The robust antitumor activity observed in Cbl-b deficient mice arising from elevated T-cell and NK-cell activity justified our discovery effort toward Cbl-b inhibitors that might show therapeutic promise in immuno-oncology, where activation of the immune system can drive the recognition and killing of cancer cells. We undertook a high-throughput screening campaign followed by structure-enabled optimization to develop a novel benzodiazepine series of potent Cbl-b inhibitors.

Managing Pregnancy and Nursing Affecting African American Women with Inflammatory Bowel Disease: Clinical Outcomes and Parenthood.

Inflammatory bowel disease (IBD) is a term for two autoimmune diseases encompassing Crohn's disease (CD) and ulcerative colitis (UC) which are lifelong diseases affecting more than 3 million adults (1.3%) in the United States. IBD is characterized by chronic inflammation of the whole digestive system which results in damage to the gastrointestinal (GI) tract.

Bioprocess decision support tool for scalable manufacture of extracellular vesicles.

Newly recognized as natural nanocarriers that deliver biological information between cells, extracellular vesicles (EVs), including exosomes and microvesicles, provide unprecedented therapeutic opportunities. Large-scale and cost-effective manufacturing is imperative for EV products to meet commercial and clinical demands; successful translation requires careful decisions that minimize financial and technological risks. Here, we develop a decision support tool (DST) that computes the most cost-effective technologies for manufacturing EVs at different scales, by examining the costs of goods associated with using published protocols.

Personally Identifiable Information in State Laws: Use, Release, and Collaboration at Health Departments.

Despite benefits to sharing data among public health programs, confidentiality laws are often presumed to obstruct collaboration or data sharing. We present an overview of the use and release of confidential, personally identifiable information as consistent with public health interests and identify opportunities to align data-sharing procedures with use and release provisions in state laws to improve program outcomes. In August 2013, Centers for Disease Control and Prevention staff and legal researchers from the National Nurse-Led Care Consortium conducted a review of state laws regulating state and local health departments in 50 states and the District of Columbia.

Healthcare employers' policies on nurse education.

The 2010 recommendation that the proportion of registered nurses with BSN (bachelor of science in nursing) degrees in the nursing workforce should increase from the current 40% to 80% by the year 2020 has shifted the focus on nurses educational progression from state legislatures-where changes in entry-level requirements were debated for decades-to the executive suites of large healthcare providers. The recommendation, contained in the report titled The Future of Nursing: Leading Change, Advancing Health, by the Robert Wood Johnson Foundation Initiative on the Future of Nursing at the Institute of Medicine, suggests that human resources policies for nurses have the potential to double the rates of college degree completions (IOM, 2010). We surveyed 447 nurse executives in hospitals, nurse-led clinics, and home and hospice companies to explore the current practices of healthcare employers with regard to this recommendation.

Are managed care organizations in the United States impeding the delivery of primary care by nurse practitioners? A 2012 update on managed care organization credentialing and reimbursement practices.

In 2014, the Affordable Care Act will create an estimated 16 million newly insured people. Coupled with an estimated shortage of over 60,000 primary care physicians, the country's public health care system will be at a challenging crossroads, as there will be more patients waiting to see fewer doctors. Nurse practitioners (NPs) can help to ease this crisis.
