Methods for the Elucidation of Protein-Small Molecule Interactions

Understanding the interactions between small molecules and proteins can be approached from different perspectives and is important for the advancement of basic science and drug development. Chemists often use bioactive small molecules, such as natural products or synthetic compounds, as probes to identify therapeutically relevant protein targets. Biochemists and biologists often begin with a specific protein and seek to identify the endogenous metabolites that bind to it. These interests have led to the development of methodology that relies heavily on synthetic and analytical chemistry to identify protein-small molecule and protein-metabolite interactions. Here, we survey these strategies, highlighting key findings, to demonstrate the value of these approaches in answering important chemical and biological questions

Developing quality indicators for the care of HIV-infected pregnant women in the Dutch Caribbean

<p>Abstract</p> <p>Background</p> <p>Effective interventions to prevent mother-to-child HIV transmission (PMTCT) exist and when properly applied reduce the risk of vertical HIV transmission. As part of optimizing PMTCT in the Dutch Caribbean we developed a set of valid and applicable indicators in order to assess the quality of care in HIV-infected (pregnant) women and their newborns.</p> <p>Methods</p> <p>A multidisciplinary expert panel of 19 experts reviewed and prioritized recommendations extracted from locally used international PMTCT guidelines according to a 3-step-modified-Delphi procedure. Subsequently, the feasibility, sample size, inter-observer reliability, sensitivity to change and case mixed stability of the potential indicators were tested for a data set of 153 HIV-infected women, 108 pregnancies of HIV-infected women and 79 newborns of HIV-infected women in Aruba, Curaçao and St Maarten from 2000 to 2010.</p> <p>Results</p> <p>The panel selected and prioritized 13 potential indicators. Applicability could not be tested for 4 indicators regarding HIV-screening in pregnant women because of lack of data. Four indicators performed satisfactorily for Curaçao ('monitoring CD4-cell count', 'monitoring HIV-RNA levels', 'intrapartum antiretroviral therapy and infant prophylaxis if antepartum antiretroviral therapy was not received', 'scheduled caesarean delivery') and 3 for St Maarten ('monitoring CD4-cell count', 'monitoring HIV-RNA levels', 'discuss and provide combined antiretroviral therapy to all HIV-infected pregnant women') whilst none for Aruba.</p> <p>Conclusions</p> <p>A systemic evidence-and consensus-based approach was used to develop quality indicators in 3 Dutch Caribbean settings. The varying results of the applicability testing accentuate the necessity of applicability testing even in, at first, comparable settings.</p
